Computer Science Highlights 2022, Harvey Mudd College

COMPUTER SCIENCE HIGHLIGHTS 2022 Update from the Department Chair 2022–2023 represents a year of innovation and growth in computer science!

We are excited to have added new staff members to our team. Chelsey Calingo joins HMC CS as our new program assistant. Chelsey is an alum of UC Riverside with a bachelor’s degree in applied math in computer science and a master’s in higher education administration and policy. She leads several student programs that aim to make our student experience more equitable, just and inclusive.

Morgan McArdle is our new departmental administrative assistant. She is an alum of Syracuse University with a bachelor’s degree in illustration with a concentration in painting.

Her artistic flair can be spotted at department events and can be seen adorning department displays.

We are also excited to be searching for multiple, new tenure-track faculty members, including in the area of climate and computer science, jointly held through the Hixon Center for Climate and the Environment and CS. This professor will help us establish our new, firstof-its-kind climate + CS joint major.

Professor Xanda Schofield ’13 and CS Clinic and Administrative Project Manager Surani Gunasena are leading efforts to reimagine our longstanding CS121 Software Development CS major requirement. Prof. Schofield will pilot a new CS in the Wild course that dives into the technical and professional skills necessary to plan, execute, document and present computational projects beyond a classroom.

Innovation and growth are keystones of our thriving faculty and student research program. Professors Katherine Breeden and

Calden Wloka collaborate with students on research that investigates developing better human gaze models in a new, state-of-the-art eye-tracking research lab. Professor Lucas Bang is incorporating ideas from the HMC CS curriculum into electronic artworks, including robotic hands that edit their own source code and video installations of neural networks that reprogram themselves to generate complex patterns of images.

Of course, this is only a tiny taste of the exciting growth and innovation happening within the department. We invite you to visit our newly relaunched website (hmc.edu/cs) to learn more and to be in touch. We’re always excited to learn of the growth and innovations of our distinguished alums.

Be well, be whole, be you!

Computing Literacy Initiatives Prioritizing Computer Science in K–12 Schools Harvey Mudd College joined national nonprofit organization Code.org and over 500 of the nation’s top industry, nonprofit and education leaders to issue a letter calling on state governments and education leaders to “update the K-12 curriculum in each state, for every student in every school to have the opportunity to learn computer science.”

“The middle and high school years are a crucial time to engage students in computer science and its creative possibilities, particularly for girls and students from other underrepresented groups in the field,” said President Klawe, a signatory on the letter.

“These years are a time when students are forming their identities, and it’s important for them to learn skills, gain confidence and see that they can succeed in tech careers—careers that are vital to our nation’s economy and

also offer creativity, flexibility, good pay and a chance to impact the world.”

The coalition behind this effort is unprecedented in U.S. education, uniting the leaders and founders of large tech companies such as Apple, Microsoft, Alphabet and Amazon, together with CEOs of companies across sectors, including American Express, Nike, Starbucks, Delta Airlines, AT&T, UPS, Walgreens and Hasbro, as well as national education organizations such as Khan Academy, the American Federation of Teachers and the National Education Association.

Over the last decade, all 50 states have taken action to expand access to computer science, including allowing computer science to count toward core graduation requirements, funding professional learning to train more teachers and creating clear certification

pathways for computer science teachers. The United States has 700,000 currently open computing jobs, but today, only 5% of high school students study computer science per year.

“Every industry is impacted by digital technology, yet not every student has the opportunity to learn how technology works,” said Code.org CEO Hadi Partovi. “Today, computer science should be a core subject, just like basic biology or algebra …. We must ensure that standards and the curricula used across the country prioritize computer science so that all students, particularly from underrepresented backgrounds, have the opportunity to participate in our digital economy.”

Computing Literacy Initiatives

(CONTINUED)

NSF Grant Supports Universal Computing Curricula A new project to develop undergraduateuniversal computing curricula will be headquartered at Harvey Mudd College.

HMC, Claremont McKenna College and Caltech are working together on ComputingAs-Literacy (CAL): Undergraduate Universal Computing, recently funded by the National Science Foundation as part of the Improving Undergraduate STEM Education: Education and Human Resources initiative.

“Computing has long been a valuable specialty and worthwhile liberal art,” says Zachary Dodds, Leonhard-Johnson-Rae Professor of Computer Science and CAL co-principal investigator at HMC, along with computer science professor Lucas Bang. “In our era, computing is also becoming a means through which other fields stage explorations and express their insights. An expressive, generative, reproducible medium, computing shares space with the venerable literacies of

critical reading, compelling presentation and cogent writing. Creative computing is joining that list, for many professional and personal paths.”

The goal of the project is to develop computing curricula to be offered among other universal undergraduate literacies, much like the traditional English composition class.

CMC and Caltech will make computing— the intellectual and professional literacy of authoring and creatively partnering with computational artifacts—required of all their undergraduates.

“HMC has required every student to make creative computing part of their skillset since before I arrived in 1999,” says Dodds. “More and more schools are looking to adapt this kind of student support within their own mission and priorities. Partnerships among those schools help everyone.”

Students will be integral to the curriculum, its development and evolution as the new Computing 1 (Comp1) courses are piloted and assessed. Dodds believes the collaboration between HMC, CMC and Caltech will be fruitful. “These three schools certainly have distinct points of pride. Even so, all three channel their students’ ambition for broad, positive impact beyond their campus experiences. Handled thoughtfully, computing can help amplify those impacts.”

The project’s premise is that our future is personal and communal, not computational.

Dodds and the project team intend CAL to replace computing as the personal and communal literacy it is. CAL’s goal is to deepen all undergraduates’ personal skillsets, both to include our era’s defining technologies—and in service to our era’s defining challenges.

Harvard Kennedy Case Study Features HMC CS The successful effort by Harvey Mudd College to raise the percentage of women majoring in computer science is now a featured case study in the Harvard Kennedy School Case Program, the world’s largest repository of case studies for educators in government and public policy.

The case study, “Harvey Mudd College: Promoting Women in Computer Science Through Inclusive Education,” details the steps HMC faculty took to redesign the core CS introductory course, engage students and incorporate inclusive pedagogy, raising the percentage of women CS majors from 10% to over 50% in less than 10 years. The case study also includes a description of how faculty assessed the effectiveness of the redesign and pedagogical changes.

Papers and Presentations of the AMISTAD Lab Research papers authored by students in Professor George Montañez’s AMISTAD Lab have been accepted to conferences, and students have gained valuable experience presenting their research to the CS community.

IEEE 2022 The IEEE 2022 International Joint Conference on Neural Networks (part of the IEEE World Congress on Computational Intelligence) accepted “Bounding Generalization Error Through Bias and Capacity,” co-authored by Montañez, Ramya Ramalingam ’21, Nico Espinosa Dice ’22 and Megan Kaye ’22. The paper was Espinosa Dice’s and Kaye’s second with the AMISTAD Lab and Ramalingam’s first. Ramalingam is a PhD student at the University of Pennsylvania, Espinosa Dice entered the CS PhD program at Cornell in the fall and Kaye has entered the workforce. Espinosa Dice and Kaye are recipients of the 2022 Don Chamberlin Research Award given by the CS department, in recognition for this and previous work.

“Identifying Bias in Data Using Two-Distribution Hypothesis Tests,” by Montañez and co-authors William Yik ’24, Limnanthes Serafini ’24, and Tim Lindsey ’23 (Biola University) was presented at the 5th AAAI/ACM Conference on Artificial Intelligence, Ethics, and Society in Oxford, England, in August. Montañez summarizes the research:

Bounding Generalization Error Through Bias and Capacity

Identifying Bias in Data Using Two-Distribution Hypothesis Tests

In supervised machine learning (i.e., classification), you are given a training dataset and you use that to produce some output (called a hypothesis) that you can use to classify future examples. While training, you have some notion on how accurate your classification hypothesis is under your training data. In the future, however, you may encounter examples you have not seen in training, so your Nico Espinosa Dice ’22 and accuracy may be different than it was in Ramya Ramalingam ’21 training. The degree to which you fail to generalize (properly classify) new training examples is called your generalization error. It is formally the expected difference between your error during training and your error on new examples, when you deploy your model in the real-world.

Traditional machine learning theory has developed ways of bounding how bad your generalization error can be, so that you have guarantees that your future performance won’t differ too much from your performance during training. In this paper, we develop ways of obtaining these same sorts of generalization error guarantees using geometric notions of algorithm bias and the degree to which a machine learning model can memorize training examples (e.g., its capacity). This work draws on recent results in the machine learning literature, but for the first time creates generalization bounds within the unified machine learning/AI framework called the Algorithmic Search Framework. This allows practitioners using the framework to have access to the same types of generalization guarantees previously only available within other theoretical machine learning frameworks.

The paper presents a way of assessing whether training data is potentially too skewed (biased) to be used in training machine learning models. For example, as a hiring manager you might see that two-thirds of recent hires were male and wonder if that was a mere statistical fluke of a fair process that hires men and women in roughly equal number or if it could indicate biases within the hiring process. Before you decide to use your hiring data to train any machine learning model, the tests would alert you to the strong possibility of bias in this data. We use two-distribution statistical hypothesis tests to determine when skewed becomes too skewed to be plausibly explained as the result of a fair process. Our methods allow us to tell the user what the closest plausible explanation for their observed data is, relative to their original hypothesized explanation. A user can then determine whether or not that plausible explanation aligns with their desired notion of fairness.

Papers and Presentations of the AMISTAD Lab

ICAART 2022 Two papers were accepted to the 14th International Conference on Agents and Artificial Intelligence (ICAART 2022), Feb. 3–5, 2022. Both papers were accepted as full papers for oral presentation in the main conference track. “For previous iterations of ICAART, the full paper acceptance rate has been less than 20%,” says Montañez, “so getting a full paper in that track is an accomplishment. The selection for oral presentation is an additional honor.”

“Vectorization of Bias in Machine Learning Algorithms”

This paper by Sophie Bekerman ’24, Eric Chen ’24 and Lily Lin (Biola University) concerns estimation of inductive orientation vectors, which have, until now, been a strictly theoretical quantity used for proving various bounds on algorithm performance.

“This work presents methods for estimating these vectors from data, allowing us to cluster and compare black-box classification algorithms based on their output behavior alone,” Montañez says.

“Since the vectors reflect underlying assumptions and biases in the algorithms, it allows us to find similarities in the inductive biases of algorithms without knowing anything about their internal structure.”

“The Gopher Grounds: Testing the Link Between Structure and Function in Simple Machines”

This paper by Anshul Kamath ’23, Nick Grisanti ’23, Sadie Zhao ’23 (Pomona College) and Montañez builds off a 2021 paper (“The Gopher’s Gambit: Survival Advantages of Artifact-Based Intention Perception” by Montañez, Cynthia Hom ’23, Amani Maina-Kilaas ’23, Kevin Ginta ’21 [Biola University] and Cindy Lay ’22 [Claremont McKenna College]) on intention-perception in traps for artificial gophers. “In this new paper, we test and challenge some of the assumptions in the original paper (such as whether coherence is strongly or only weakly correlated with functionality) and see if producing traps using genetic algorithms changes the properties of the produced traps in terms of their coherence and functionality,” says Montañez. This paper is part of a larger body of work that includes a third paper still in development, looking specifically at applying the hypothesis tests from the Hom et al. paper to the genetic-algorithm produced traps.

Amani Maina-Kilaas ’23 Recognized for Research and Scholarship Computer science and mathematics major Amani Maina-Kilaas ’23 is a recipient of two prestigious national awards.

Maina-Kilaas received the Computing Research Association’s (CRA) 2022 Outstanding Undergraduate Researcher Award, which celebrates undergraduates at North American colleges and universities who demonstrate outstanding potential in an area of computing research. He is a member of computer science professor George Montañez’s lab AMISTAD (Artificial Machine Intelligence = Search Targets Awaiting Discovery).

“I joined the lab in the summer after my freshman year and worked with Cynthia Hom ’23, Kevin Ginta ’21 (Biola University) and Cindy Lay CMC ’22 to investigate how the ability to perceive intention can advantage virtual agents,” he says. “We created simulations to study intention perception directly through a multi-agent, prey-predator encounter and a two-player, game-theoretic adversarial situation and also indirectly through having agents analyze artifacts left behind by another. That summer resulted in three publications, two for which I was lead author and one for which I was co-lead author with Cynthia. My nomination and selection for the award is primarily based on that summer research, but I have also since continued with AMISTAD throughout the academic year, working mostly on collating past research from the lab.”

Based upon exemplary academic performance, ingenuity and unique aptitude for research, Maina-Kilaas ’23 was one of two Mudders selected by the Astronaut Scholarship Foundation to join the elite group of Astronaut Scholars for the 2022–2023 academic year.

Offered to students pursuing degrees in STEM, the 2022 ASF Astronaut Scholarship awards scholarships up to $15,000. Other benefits include networking and mentoring opportunities with astronauts, alumni and industry leaders; participation in the Michael Collins Family Professional Development Program; and a paid trip to attend ASF’s Innovators Week, which provides an opportunity for the Astronaut Scholars to present their research at a technical conference.

Maina-Kilaas has interned as a software engineer at Stripe and tutored peers in programming languages and introductory

computer science. This summer, with University of Southern California computer science professor Muhao Chen, he researched natural language understanding (specifically, machine common sense) in the Language Understanding and Knowledge Acquisition Lab at the Information Sciences Institute.

The work of a researcher appeals to him, so Maina-Kilaas will pursue a PhD in computer science. “I would rather spend my career generating new knowledge and advancing the field as a university professor or as an industry researcher,” he says.

“As a model for search problems, we studied deduction games: those where you make guesses and learn information about some secret value from each guess,” she says. “Solving a deduction game—figuring out the correct sequence of guesses to locate a secret for each possible secret—corresponds to creating a

search algorithm. In my time with this group, I implemented an algorithm for solving deduction games, performed experiments and derived some theoretical results.” After graduation, Taylor joined Meta as a software engineer.

CRA Honorable Mention The Computing Research Association recognized computer science and mathematics major Mia Taylor ’22 with an honorable mention, given to students whose work CRA considers exemplary. She conducted research on synthesizing search algorithms with computer science professor Lucas Bang.

Fourth Place in Citadel Terminal Global Championship A team of Harvey Mudd College students placed fourth in Citadel’s 2022 TERMINAL global championship, winning a $5,000 prize and beating teams of experienced players and PhDs from top universities around the world.

In November 2021, HMC students placed first and third in the TERMINAL West Coast regional event in November, and they were invited to the summer global championship.

Members of the first-place team— Milo Knell ’25 (CS and math) and Alan Wu ’25 (CS and math)—joined with a member of the thirdplace team, Sahil Rane ‘25 (CS and math), to form the new team. All participated in summer research in the AMISTAD Lab (Artificial Machine Intelligence = Search Targets Awaiting Discovery) of computer science professor George Montañez.

Their experience at the West Coast competition and their work together on campus helped give the Harvey Mudd team the edge in a contest where Citadel gathers

the best players from around the world to compete, allowing the asset management firm to identify talented programmers. Competitors write code and strategize to beat other teams in TERMINAL, a tower defense game where players build a base and send units to attack the opponent. Players pick moves that are executed simultaneously. Health is lost when an enemy unit reaches the opponent’s edge, and the game ends when a player reaches 0 health.

The HMC team gave this description of its strategy: “We rewrote the pathfinding code of the official game library, to create a simulator that’s fast enough to evaluate ~50 board states per round. We made some simplifying assumptions about the game to allow us to simulate many more board states at a minimal cost of accuracy. Using this simulator, we were able to test out many different attack strategies to find out which was optimal. We came up with strategies to adapt our base to maximally exploit weaknesses in the enemy setup. In our

HARVEY MUDD COLLEGE | COMPUTER SCIENCE HIGHLIGHTS 2022

strategy, we do not build our base until the opponent does so we can ensure that we mirror their base. Most players have a strong side and a weak side, and by matching our strengths to their weak we are confident we can exploit their weak side more than they can ours.

“Another thing we are proud of is our smart banking, where we compute the tradeoff between sending units now and next turn versus waiting for an extra turn to get more money to send a stronger attacking force. Since saving up for several rounds is so impactful, we wrote a heuristic along with simulations to predict when the enemy would send their attack so we could counter it by sending defensive units.”

Wu says, “Part of the reason we did so well is that we sent many units to stop enemy attacks and generally had fewer times where we sent defensive units when the enemy did not attack (a waste of money).”

STUDENT NEWS

First-Gen Pride It wasn’t until her junior year of high school that Shanni Lam ’22 realized she was on her way to becoming a first-generation college student.

“I just assumed that most people were first-gen, because that’s how it was in my community,” she says. “I didn’t understand why colleges thought it was such a big thing, but now that I attend Mudd, I’m a lot more proud and a lot more vocal about it.”

Today, the math/computer science major is helping other first-generation students find their way. Lam leads Project Decode, a studentrun organization for first-generation and/or low-income students, and served as a mentor for Mudd’s Summer Institute program, which helps underrepresented incoming first years with the college transition process.

“First-generation students have to overcome a lot more barriers than other students, so I have a newfound appreciation for my identity,” Lam says.

What are the barriers first-generation college students face?

An obvious barrier is that we don’t have parents who can help with applying to college.

First-gen students are also often low-income and attend more average (or below average) public schools, where the curriculum is less likely to prepare them for a college curriculum, especially Mudd’s curriculum. Another big barrier is a feeling of alienation. Prior to Mudd, I went to schools where most students were people of color and on free/reduced lunch. I only knew a handful of students whose parents went to college. Now, it’s weird hearing people tell me their parents are research biologists or engineers. It’s also weird hearing people speaking to their parents in full English, seeking job advice and getting help on their engineering homework, while I do the opposite, helping my parents find jobs. It reminds me how deeply class inequality hits in America.

Tell us about Project Decode.

Project Decode is Mudd’s student-led affinity group that provides guidance and networking

for first-generation and low-income students. I serve as the group’s co-president and help plan many of the events, including workshops to help students understand things like financial aid and healthcare. The organization is also a space for people to hang out, meet new people and discuss the first-generation lived experience and issues at Mudd.

Through your experiences with Project Decode and Summer Institute, what have you learned about how Mudd can support its first-gen students?

A major way is through recruiting and admissions. We need to have a more socioeconomically diverse student body. It’s important for first-gen students to know that there are others just like them at Mudd. Firstly though, most first-gen students likely won’t even know what Mudd or the other Claremont Colleges are. I didn’t until I lived literally 15 minutes away from Claremont my junior year, and even then, I only ever felt pushed toward public colleges.

You study many languages. What do you enjoy about that?

I come from an interesting multilingual background. My parents and grandparents are ethnically Chinese, born and raised in Vietnam, so they speak Cantonese and Vietnamese.

It wasn’t until recently that I learned that my dialect of Cantonese apparently has a Vietnamese accent and sounds somewhat old-fashioned and rural, as if I was from the ’60s. This motivated me to learn more about Cantonese, as it reinforced that every language has its own rich varieties. I am also learning Mandarin because it’s interesting to see the phonological and grammatical similarities and differences between Mandarin and Cantonese.

Because of Sinospheric influence, I can also find similar sounding words in Vietnamese and Korean, the latter of which I began learning because I was briefly interested in K-pop and K-dramas. Since eighth grade, I’ve studied Spanish because it was very commonly spoken in the places I lived and most often offered at

the high schools I attended. It’s very enriching to learn about different cultures and writing systems.

What do you like to do in your spare time?

I consider myself a film buff, so I like to watch a lot of movies. I also like to go to the desert; it’s my favorite ecosystem. That sounds kind of weird, but it’s a nice place with its own flora and fauna with minimal light and noise pollution to slow down and think peacefully. I also like to go to different ghost towns or abandoned places. When I’m driving and see abandoned structures, I wonder what happened to them and feel nostalgic. It’s cool to explore and think about the past.

What do you hope to do after graduation?

There are a few paths I’m considering. One is data analytics. More recently, I’ve been thinking about consulting. I feel like I’m good at quick math and being able to provide recommendations for other people. It would allow me to use more of my communication skills. I’ve also thought about being a community college professor because I’ve had some experience with tutoring and find it to be more accessible and widely impactful.

Spotlight on Kurt Dresner ’02 Kurt Dresner (CS/math) received the HMC Alumni Association’s Spotlight Recognition Award. He is an innovator in the field of autonomous intersection management. He and a co-author were awarded the International Federation on Autonomous Agents and Multi-Agent Systems’ Influential Paper Award for setting a new direction in the research of transportation systems for autonomous vehicles. In a world where drivers don’t get distracted, don’t fall asleep and can plan using more than just red, yellow and green, there’s no need to stop for an empty intersection. He got to work imagining such a future and the ways we could coordinate autonomous vehicle traffic for both increased throughput and safety.
