Speaker
COURSE OBJECTIVES:

As developers, engineers, scientists or students if we analyze data or want to learn how to analyze data, we need to have the required skills. We need to learn those skills helping us to improve our status in our current job, get a better job and be successful in next interviews we will have. Dimension reduction is among the subjects necessary to know if you want to be successful or become successful as developers, scientists or engineers.

In this workshop, you will learn about widely used dimension reduction methods such as PCA, ICA, t-SNE, and UMAP. You will learn how to explore them to reduce dimensionality of your data in Python, how to use methods like PCA in supervised learning schemes and how to improve your reports using visualization techniques like t- SNE. This will be a hands on workshop in which we will work on multiple datasets and will learn how to implement each one of the aforementioned methods on them in Python

COURSE SCHEDULE:
  • Session 1: Mar. 5th Tue 10am-12pm PST
  • Session 2: Mar. 7th Thu 10am-12pm PST

COURSE INCLUDE:
  • 8 Topics / 4 hours live talks
  • 3 hands-on code labs
  • Real time interactions with instructors
  • Watch sessions replay, disucssions, course notes any time

WHO SHOULD LEARN:
Dimensionality reduction is a mandatory skill for data analysis. The materials are prepared in a way that both beginners and experts working with data in any level will learn how to use each one of the dimensionality reduction methods.

PREREQUISITE:
Reasonable background in programming with python

STATUS
The course live sessions have ended, you can still enroll to learn the course with recorded videos, slides, interactive code labs on jupter notebook, course notes and discussions.
Not refundable.

Module 1: Introduction to dimensionality reduction
  • Feature selection versus feature extraction/construction
  • Preserving global versus local structure of data
  • Reducing dimensionality of multiple datasets using PCA and ICA

Module 2: Dimensionality reduction for visualization and classification
  • Using t-SNE to preserve local structure of data
  • Correct interpretation of t-SNE plots
  • UMAP versus t-SNE
  • Code lab 2 (t-SNE and UMAP for visualization)
  • Use new dimensions of some of these methods in supervised learning models
  • Code lab 3 (Using reduced dimensions for building classification models)
