This is my Google Summer of Code 2019 Project with Red Hen Lab.
The Project goal is to design and develops an online course, to teach deep learning for students in the humanities and social sciences. The course will contain basic deep learning theory and labs case studies from multimodal communication.
Project Mentors: Francis Steen, Mark Turner and Rajesh Kasturirangan.

Example
-
Loss function: Mean Squared Error
-
Why we use squared error instead of raw error?
The empirical loss measures the total loss over the dataset. Loss function is a function of the Weight.

- Gradient Descent
- Minimize error
- What is Gradient Descent?
- Greedy algorithm
- Like Hiking Down a Mountain
- Simple Example
- Local minimum
- Compute Graph
- Chain Rule
- Back Propagation
The error is propagated backwards to the other layers.

In this chapter, the student will learn how to teach the computer to classify handwritten digits by using MNIST dataset in Python.
DataSet: The dataset I choose for this part is MNIST(Modified National Institute of Standards and Technology) dataset, which has a training set of 60,000 examples, and a test set of 10,000 examples. It is a subset of a larger set available from NIST(National Institute of Standards and Technology) which gives data set of over 800,000 images of handwritten digits from 3,600 writers. The digits have been size-normalized and centered in a fixed-size image.
