III. Methodology

1. Data Collection and Preprocessing

Fig- 1 : DataSet

After acquiring the dataset, preprocessing techniques were applied to clean and prepare the data for analysis. This involved handling missing values, outliers, and inconsistencies. Additionally, feature scaling and normalizationtechniqueswereemployedtostandardize thedataandensureuniformityacrossdifferentfeatures.

2. Feature Selection

Feature selection is the process of identifying and selectingasubsetofrelevantfeaturesorvariablesfroma larger set of available features in a dataset. The goal of feature selection is to improve model performance, reduce computational complexity, and enhance interpretabilitybyfocusingonthemostinformativeand discriminative features. Featureselection plays a crucial role in improving model performance and interpretability. In this stage, relevant features were identified based on domain knowledge and statistical analysis. Techniques such as correlation analysis, principal component analysis (PCA), and recursive feature elimination (RFE) were utilized to identify the mostinformativefeaturesforpredictingdiabetesrisk.

3. Model Development

Three machine learning models were chosen for developing the Insu-Learner system: Decision Tree, Random Forest, and Naive Bayes. These models were selectedbasedontheirsuitabilityforclassificationtasks, robustness,andinterpretability.

3.1. Decision Tree: Thedecisiontreealgorithmemployed in the Insulearner system plays a pivotal role in predictingdiabetesonsetbasedoninputfeaturessuchas pregnancies, glucose levels, blood pressure, skin thickness,insulinlevels,BMI,diabetespedigreefunction, andage.Thissectionelucidatesthemethodologybehind the decision tree algorithm, its implementation, and the mathematicalcalculationsinvolved.

The decision tree algorithm operates by recursively partitioning the feature space into subsets, aiming to create homogeneous subsets with respect to the target

variable,whichinthiscaseisthediabetesoutcome(0for no diabetes, 1 for diabetes). The splitting of the feature space is guided by criteria such as information gain or Gini impurity reduction. In our implementation, we utilize the entropy criterion for splitting, maximizing informationgainateachnodewhilelimitingthedepthof thetreetopreventoverfitting.

3.1.1ExplanationoftheAlgorithm

i)EntropyCalculation:Entropymeasurestheimpurityor randomness of a dataset. Given a dataset D with two classes(positiveandnegative),the entropyiscalculated as:

Entropy(D)=-p+log22(p+) – p-log2(p-)

Wherep+andp-representtheproportionsofpositive andnegativeinstancesinthedataset,respectively. ii) Information Gain: Information gain quantifies the effectiveness of a particular feature in classifying instances. It is computed as the difference between the entropy of the parent node and the weighted sum of entropies of the child nodes resulting from splitting on thatfeature.

IG(D,f)=Entropy(D)- ∑

Entropy(Dv)

Where f represents a feature, D is the dataset, Dv denotes the subset of D for which feature f has value v, and V isthenumberofdistinctvaluesoffeature f iii) Tree Construction: The decision tree is constructed recursively by selecting the feature that maximizes information gain at each node. The process continues until a stopping criterion is met, such as reaching a maximum depth or having no further gain in information.

3.1.2ExampleCalculation

Consider a simplified dataset with two features, glucose level and BMI,anda binary outcomeindicating diabetes status. The decision tree algorithm aims to predict the diabetesoutcomebasedonthesefeatures.Here'sastepby-step calculation of the information gain for splitting ontheglucoselevelfeature:

Step 1: Calculate the entropy of the parent node using theformula:

Entropy(D)=- log2 2

Step2:Calculatetheentropyofthechildnodesresulting fromsplittingontheglucoselevelfeature.

Step 3: Compute the information gain using the formula mentionedearlier.

By repeating this process for each feature and selecting the one with the highest information gain, the decision tree algorithm constructs a tree that effectively

partitionsthefeaturespace,enablingaccurateprediction ofdiabetesonset.

3.2 Random Forest: The Random Forest algorithm utilizedintheInsulearnersystemisapowerfulensemble learning technique that combines the predictions of multiple decision trees to improve predictive accuracy and mitigate overfitting. This section outlines the methodologybehindRandomForest,itsimplementation, and the mathematical concepts underpinning its operation.

Random Forest operates by constructing a multitude of decision trees during the training phase and outputting the mode of the classes (classification) or the mean prediction (regression) of the individual trees. In Random Forest, each decision tree in the ensemble is trained independently using a subset of the original dataset. The final prediction is then determined by aggregating the predictions of all individual trees. Let's consider a binary classification problem where the outcome variable y represents the diabetes status (0 for non-diabetic, 1 for diabetic), and we have n instances in thedataset.

i)BootstrapSampling:RandomForestemploysbootstrap samplingtocreatemultipledatasets,eachusedtotraina decision tree.Givenanoriginal datasetwith n instances, a bootstrap sample of size n is created by randomly sampling with replacement. The probability of selecting aninstanceforthebootstrapsampleis 1/n.

ii) Feature Randomization: At each node of the decision tree,arandomsubsetoffeaturesisselectedforsplitting. Let's denote the total number of features in the dataset as m,andthenumberoffeaturesconsideredforsplitting ateachnodeas mfeat , Where mfeat ≤ m

iii)Tree Construction: Each decision tree is constructed using the bootstrap sample and the selected subset of features.Thetreeisgrownrecursivelybysplittingnodes based on a splitting criterion such as Gini impurity or informationgain.

iv)Voting for Classification: For classification tasks, the final prediction of the Random Forest is determined by majority voting among the predictions of individual trees. Let's denote the predicted class for the ith instance by ̂ i, Where i = 1, 2 , 3,…n. Thepredictedclass for the ith instance in the Random Forest ensemble, denotedas ̂ RF,i ,Whereiscomputedas:

̂ RF,I =argmaxk ∑ ̂

where Ntrees is the total number of trees in the Random Forestensemble, k representstheclasslabels(0or1for binaryclassification),andI(.)istheindicatorfunction.

3.2.1ExampleCalculation:

Suppose we have a Random Forest ensemble consisting of 100 decision trees. For a new instance with feature valuesXnew =[150,30](glucoselevel=150,BMI=30),we obtainthefollowingpredictionsfromindividualtrees:

̂ 1 =1, ̂ 2 =0,..., ̂ 100 =1

The final prediction for the instance using majority votingwouldbe:

̂ RF =argmaxk ∑ ̂

Inthiscase,ifthesumofinstanceswhere ̂ j =1is greaterthanorequalto50,thefinalpredictionwillbe ̂ RF =1;otherwise, ̂ RF =0.

33 Naive Bayes: Naive Bayes is a probabilistic classifier based on Bayes' theorem with strong independence assumptions between features. Despite its simplicity, Naive Bayes often performs well in practice, especially for text classification and other high-dimensional datasets.

3.3.1 OverviewofNaiveBayesAlgorithm i)Bayes'Theorem:NaiveBayesreliesonBayes'theorem, which calculates the probability of a hypothesis (class label) given the observed evidence (features). Mathematically,itisrepresentedas:

P(Ck |x )=

Where:



P(Ck |x) istheposteriorprobabilityofclass Ck giventhefeaturevector x

P(x | Ck ) is the likelihood of observing the featurevector x givenclass Ck.

 P(Ck ) isthepriorprobabilityofclass Ck.



P(x ) is the probability of observing the feature vector x

ii) Conditional Independence: Naive Bayes assumes that the features are conditionally independent given the classlabel,whichmeansthatthepresenceofonefeature does not affect the presence of another feature. This simplifiesthecalculationofthelikelihoodterm P(x|Ck ) , makingthealgorithmcomputationallyefficient.

3.3.2. ApplicationtoDiabetesPrediction

i) Data Representation: In the context of diabetes prediction, the feature vector x represents the clinical attributes of an individual, such as glucose levels, blood pressure,BMI,etc.

ii) Model Training: During the training phase, Naive Bayes estimates the prior probabilities P(Ck ) and the class-conditionalprobabilities P(x | Ck ) fromthetraining data.

iii)Prediction:Givenanewfeaturevectorx,NaiveBayes calculates the posterior probabilities P(Ck |x ) for each

3.3.3.MathematicalCalculation

The mathematical calculation involved in Naive Bayes primarily revolves around estimating the prior and conditional probabilities from the training data. Let's denote:

 count (Ck) is the total number of instances in class Ck

 Laplace smoothing (additive smoothing) with α=1isusedtohandlezeroprobabilities.

3.3.4.ExampleCalculation

Forinstance,let'sconsiderpredictingthediabetesstatus (0or1)basedonthefollowingfeaturevector x = [150, 30, 70, 35, 0, 32, 0.5, 40]. We can compute the posterior probabilities P(Ck |x ) for each class using Bayes' theorem and select the class with the highest probabilityasthepredictedclass.
