(Day 14) Andrew Ng's Machine learning specialization

Ivan Ivanov · January 15, 2024

Hello :) Today is Day 14!

A quick summary of today:

  • Advanced learning algorithms - Coursera

Andrew Ng and Professor Yaser S. Abu-Mostafa’s teaching methods are similar so I am really enjoying this!

Today I learned about:

  • model selection

When selecting a model, keep in mind the words “Do not use test data.” You must select a model based on the training and verification datasets to evaluate the model with test data!

  • bias vs variance, and regularization

Andrew Ng said that bias and variance theory can be understood, but the difference can only be understood when creating a model. In the future, I should consider bias and variance when making a model

In neural nets, lambda can also be an important hyperparam

  • decision trees and neural nets

Today was great! Tomorrow I will learn about Unsupervised Learning, Recommenders, Reinforcement Learning

That is all for today!

See you tomorrow :)
