Here's what you'll get inside (two full exams with solutions!): Exam 1 (2017/2018): Conceptual Questions: Master the fundamentals with questions on Naive Bayes parameter estimation, Bias-Variance tradeoff, Parametric vs. Non-parametric models, and more. Algorithm Selection: Learn to identify which classifiers (Logistic Regression, SVM, Decision Trees, KNN) can achieve zero training error on a given dataset. Error Calculation: Practice computing Mean Square Error (MSE) from residual plots. Clustering: Understand the advantages and disadvantages of Hierarchical vs. K-Means clustering, and the difference between Single and Complete Linkage. Deep Learning: Get clear explanations of the ReLU and Pooling layers in CNNs. K-Means Simulation: A detailed, step-by-step walkthrough of the K-Means algorithm to identify two clusters from given data. Exam 2 (2018/2019): Decision Boundaries: Identify learning algorithms (Decision Trees, Logistic Regression, KNN) from their decision boundaries and calculate training errors. Decision Trees & Entropy: Calculate Entropy and Conditional Entropy to build a full decision tree from a given dataset. SVM: A full derivation of the SVM Margin in terms of the weight vector (W). Comprehensive Questions: Covering parametric vs. nonparametric methods, smoothing in Naive Bayes, feature selection vs. dimensionality reduction, and the limitations of a single perceptron. KNN True/False: Understand the nuances of the K-Nearest Neighbor classifier. Neural Network Forward Pass: Compute the output of a neural network with ReLU and Sigmoid activations step-by-step. CNN Parameter Calculation: Calculate the number of parameters and the output feature map size for a convolutional layer.
