## EE 525X: Spring 2018

## Data Analytics in Electrical and Computer Engineering

### Course Summary

Introduction to a variety of data analysis techniques -- particularly those relevant to electrical and computer engineers. Topics include techniques for classification, visualization, and parameter estimation, with applications to signals, images, matrices, and graphs.This is a graduate-level course focusing on data analysis foundations. Particular emphasis will be placed on the

**principles**of state-of-the-art data processing techniques; on methods to analyze correctness and efficiency of such techniques; and on the evaluation of these techniques on real-world test datasets.

### Course Information

**Lectures**: MW 4:10pm-5:30pm, Science 0277.

**Grading**: Six (6) homework problem sets (60%); final course project (40%).

Problem sets will be posted roughly once every fortnight on Blackboard. Problem sets will involve a mix of theory and practical implementation.

The final course project can be carried out either individually or teams of two (2). The project will involve either conducting research on a specific topic, or implementing and evaluating modern data analysis techniques on a real-world dataset.

**Pre-reqs**: Knowledge of undergraduate probability (EE 322 or equivalent); familiarity with linear algebra and optimization.

### Syllabus

- Review of mathematical basics.
- Classification: Nearest neighbors, kernel methods, SVMs.
- Matrix analysis: Singular value decomposition, matrix factorization.
- Graph analysis: Connectivity, trees, random walks.
- Data visualization: Clustering, nonlinear dimensionality reduction.
- Streaming algorithms: Distinct elements, frequency moments, heavy hitters.
- Sampling: Sparse recovery, compressive sensing, matrix completion.

### Book

A. Blum, J. Hopcroft, and R. Kannan,*Foundations of Data Science*.

### Notes

Here is a single monograph containing all lecture notes from the Spring '17 edition. Notes were made using (pandoc-flavored) Markdown, which is a real lifesaver if one wants to quickly typeset math-heavy lecture resources. (Thanks, Boaz Barak, for the idea.)### Lecture Schedule (tentative)
