PlanGAN Recently, Generative Adversarial Networks have proven capable of producing high-quality extrapolations in the feature space of a given dataset. PlanGAN proposes that these developments are bringing new possibilities to design and analysis. Term: Spring 2017 Critic: Liz Diller Advisor: Jesse Reiser Duration: 12 Weeks

In order to make value judgments in a new drawing regime, there need to be new kinds of analysis that look closer than humanly possible. The first step in this direction was the training of an image classifier on a dataset of architectural components. A dataset of approximately 700 images was used to retrain several different top performers on the ILSVRC challenge. Densenet-121 was selected as it consistently achieved the highest validation accuracy on the 300 validation images. The best performance was just under 86%. Second retraining and verification results: ~80% accuracy.

Visualization of the best-performing Densenet’s results show the task that it is undertaking is sometimes difficult even for human experts. The images were inverted as earlier experimental results suggested that white lines on black backgrounds yielded more consistent results. The dataset was split into five classes of architectural components: columns, stairs, doors, rooms, and windows. These images show examples of the test set with their corresponding class scores from the image classifier and the correct class above the image. The images in the test set are taken from plans ranging from antiquity to the present.

5


The sliding window detector was deployed on a number of collected architectural drawings, both canonical and quotidian, ranging from antiquity to the present.

The five classes that the detector was trained on are color-coded in the first analysis map. A threshold of greater than 60% was used to filter false positives. This value was selected from the verification phase of the retrained detector where completely white images would return false positives as ‘rooms’ or gridded floor patterns as ‘stairs’ at or below 60%. However, the sliding window segmentation still has many pathologies. Here, highly segmented walls are returned as ‘columns’ due to the inherent inability to understand the entire context of each subset of the image.

To visualize how confident the system is, the sliding window detector creates a parallel ‘confidence map’ scored from 0 to 1.0. Here, another pathology is shown. Empty space outside the walls is returned as a ‘room’ with 100% confidence. In spite of its shortcomings, the detector does show some promising results, frequently able to detect even highly irregular stairs or find unusual interior or exterior windows.

Epoch: 5 Because of the pathologies shown in the sliding window detector, an autoencoder was ultimately used for generating the analyses. This enabled the system to discover its own features of the dataset while learning a compressed representation of the images. This compression was restricted to a 100-dimensional vector as previous experiments had shown that less than 10-dimensions was too restrictive and 100 to 1000 gave diminishing fidelity to the original images.

Epoch: 15 The autoencoder was trained on batches of 16 images over 100 epochs with stochastic gradient descent.

Epoch: 95 With this training setup, most images are able to be reproduced with good visual fidelity. Notably, many very small features are still not captured very well. Light gray ‘fuzz’ is usually an artifact of dimensions or very light floor patterns that are drawn in the base images. As the entire dataset is processed at 512x512 pixels, this loss of information likely comes from a combination of the small image size and the compressed size of the encoded vector.

Visualization of the 100-D embedded vectors of two plans. Some visual similarities are discernible, but the embeddings are not very useful without computation.

Tests of the viability of embeddings to be able to associate similar drawings showed that L2 pairwise distances of <~8.5 indicated highly similar images. In this case, the same image rotated 90 degrees scores ~5.95

Graphing the L2 pairwise distance for the embedded vector as the image is rotated through 360 degrees shows the entire range of distances.

The embedded vector proves capable of making meaningful associations beyond pixel values. Here showing that two visually and formally different plans by the same author (Hans Scharoun) are highly correlated (L2 < 8.0).

9


The plans dataset was then used as the source material for a generative adversarial network designed to generate images at resolutions of 1024x1024. Although these images are visually similar to architectural plans, close examination shows that they exhibit many pathologies of generative models. Many features that are key to the meaning and interpretation of plans like the symbolic encoding of doors and windows, are not present. However, the images do exhibit some amount of novelty in composition and structure. In the above image, the pattern of diagonal â&#x20AC;&#x2DC;columnsâ&#x20AC;&#x2122; is a feature that is not present in the dataset and its overall form is a fairly well-resolved combination of several real examples.

10


This plan exhibits a similar composition to that on the facing page, but takes a very different route with its structure. Here, the drawing is defined by many sliding orthogonal walls with what appear to be underdeveloped stairs or escalators running down the central axis. Results like these, while admittedly very rough, suggest that the processing of precedents into new, yet, familiar forms is not a strictly human domain. Rather, the process is automatable and designable, and thus open for critique and improvement.

11


Some of the generated samples follow fairly typical constructions. The plan at left is composed primarily of ortholinear walls enclosing many rectangular spaces. The plan below, however, is comprised of features that are plausible, like a series of massive parallel walls adjacent to a field of thinner surfaces and patterns that fade in and out of focus. Drawings like these show that even this rudimentary system is capable of recreating the world similar to how it exists, as well as proposing possible, yet novel, constructions.

The facing page shows a series of drawings that are produced from a smaller dataset that focuses on a single author. Experiments like these suggested that there is a lower limit to the number of features that define a productive dataset. However, the models were consistently able to provide more extensive examinations of particular source images this way.

14


The trained autoencoder is used on a set of both real and generated plans to produce embedded vectors that reduce the dimensionality of the plans from 512x512x3 to 1000 for use in a tSNE plot. This becomes a kind of formal analysis operating at many levels of abstraction that can be used to draw comparisons between disparate drawings. The image at left shows a neighborhood created from a castle, Morphosisâ&#x20AC;&#x2122;s plans for the Emerson School in Los Angeles, and one of the generated plans. The generated images are considered to be successful if they â&#x20AC;&#x153;fill the holesâ&#x20AC;? of this plot. That is to say, its features are familiar yet novel, capable of bridging the feature space between highly diverse drawings.

This selection shows generated plans that are considered to be less successful. These have ended up in nearly homogeneous neighborhood. It is almost exclusively generated plans. This is interpreted as their having features that are too localized, making them incapable of exploring unrealized parts of the feature space.

Where the cantilever crosses the existing fort wall, columns increase in density to resist the overturning moment on the rear of the truss. This creates gradual transitions from walldefined spaces to column-defined spaces.

In the cantilevered gallery, trusses are concealed on the interior to provide diverse gallery spaces. At the periphery, the trusses are revealed as they cross the angular apertures. The complexity of the facade is resolved on the interior as these varied semi-trapezoidal openings.

Once inside the atrium, the collected sinuous surfaces separate and stretch the space of the gallery into a procession rather than a destination. This dissolves the act of waiting into a spatial experience.

The proportion of glazed to opaque facade increases from south (right) to north (left). On the roof, the angle of the wrinkled skin largely shields the skylights from harsh southern light, while allowing light in from the north.

The vertical south (right) facade has a lower proportion of glazed area. The panels that are glazed use the intense angle to completely shield the glass from solar radiation in summer months, and allow some in during the winter. On the underside, the density of the folds increases to create a radiant reflecting system that augments the covered area offered by the cantilever with partial environmental conditioning for visitors waiting in the security line.

Final simulations are run with robotic columns supporting a flexible roof structure. This allows the enclosed volume to expand and contract based on real-time requirements of occupancy. The convex hull of the column flock is used as one of the simulation goals. Their logic prioritizes overall stability of flexible roof and all columns. 1/3rd points of square structure. In order to preserve global stability, columns work as a group to enclose points within convex hull. Column in danger zone. When a single column is in danger of collapse from overstress or supporting too much of the roof, it calls for help from its neighbors.

The lowest-level column goal is to optimize self-stress and minimize global bending. This amounts to maximizing individual separation within roof area.

End Effector

The custom-fabricated end effector was designed to maximize the abilities of easily accessible arduino hobby parts. A maximum feed rate of 1.5â&#x20AC;?/min was calculated as the most effective for the deposition of the material. This was achieved by gearing the hobby motor down by a factor of 60:1. The reduction gearing also increased the torque to roughly 8ft/lbs. 64
