Essential Mathematics for Machine Learning

Essential Mathematics for Machine Learning

This session will focus more on the essential mathematics underlying the most important machine learning concepts and algorithms. This makes easy to understand the algorithms better, and further helps to fine-tune the hyper-parameters involved in these algorithms.

Duration: 2.0 - 2.5 hours white-board session (no coding).

Meetup Location: Office No. 401, 4th Floor, Unity Gold Building, near Deccan PMT Bus Stop, Opp. Z-Bridge, Deccan, Pune.

Pls read these blog prior to the session. These things we have already covered in the 1st part of Essential Mathematics for ML.

1. For Machine Learning Basics: https://www.analyticsvidhya.com/blog/2015/06/machine-learning-basics/

2. Basics of Machine Learning Algorithms (ignore the codes, for first-timers): https://www.analyticsvidhya.com/blog/2017/09/common-machine-learning-algorithms/

3. The Bias-Variance Trade-off: https://www.kdnuggets.com/2016/08/bias-variance-tradeoff-overview.html

4. Linear Regression & Regularisation: https://www.analyticsvidhya.com/blog/2017/06/a-comprehensive-guide-for-linear-ridge-and-lasso-regression/

THE CONTENTS GIVEN BELOW WILL BE STRICTLY FOLLOWED. NO GENERAL INTRODUCTION TO MACHINE LEARNING will be done. Participants are expected to know about Supervised and unsupervised learning, the basic meaning of Classification, Regression, and Clustering, concepts of overfitting and underfitting, Bias & Variance. Links given above.

Part – D: Applications to Machine Learning with worked examples
Ø Linear Regression: Least Squares Solution
Ø Stochastic Gradient Descent (SGD) for Linear Regression (also Batch and mini-batch GD will be discussed).
Ø Quick Regularisation Revision: Ridge, Lasso, ElasticNet
Ø Logistic Regression
