Train/dev set error and bias/variance

When the number of training samples tends to infinity, the changing trend of the model trained on the data set:

How does the bias change

- Get more data for better generalization on unseen data.
- Regularization (L2 Regularization, Dropout, Data Augmentation, etc.). 
...

Ways of Reducing Variance

Bias and Variance are two fundamental concepts for Machine Learning, and their intuition is just a little different from what you might have learned in your statistics class. Here the video go through two examples that make these concepts super easy to understand.

Decision trees are a simple way to convert a table of data that you have sitting around your desk into a means to predict and classify new data as it comes.

"In this video, I move beyond the Simple Perceptron and discuss what happens when you build multiple layers of interconnected perceptrons ("fully-connected network") for machine learning."
