ISYE 6501 FINAL EXAM WITH COMPLETE SOLUTION 2022/2023 1. Factor Based Models: classification, clustering, regression. Implicitly assumed that we have a lot of factors in the final model 2. Why limit number of factors in a model? 2 reasons: overfitting: when # of factors is close to or larger than # of data points. Model may fit too closely to random effects simplicity: simple models are usually better 3. Classical variable selection approaches: 1. Forward selection 2. Backwards eli...

Interaction (definition) - answer-Effect of one variable on target variable depends on the value/level of another variable. GLM Description (idea) - answer-GLMs relate a function of target mean linearly to a set of predictors. Target itself is not transformed. Recursive binary splitting (idea) - answer-divide feature space recursively into a set of non-overlapping regions of relatively homogeneous observations until a stopping criterion is reached. Random Forests (idea) - answer-Reduce ...

What is deep learning? - an area of machine learning, focuses on deep artificial neural networks which are loosely inspired by brains. - Application: computer vision, speech recognition, natural language processing. Deep learning is a class of machine learning algorithms that:[10](pp199-200) - use a cascade of multiple layers of nonlinear processing units for feature extraction and transformation. Each successive layer uses the output from the previous layer as input. learn in supervised ...

The curriculum begins with Module 1: Hypothesis Testing, which lays the groundwork for statistical analysis in biomedical data. It starts with an introduction to Python, essential for the practical components of the course, followed by reviews of probability and statistics to refresh and solidify foundational knowledge. Students learn various hypothesis testing methods, including parametric and non-parametric statistics, the considerations for multiple comparisons, and resampling-based statistic...
