Overview
Syllabus
Intro
Deep Learning = Learning Hierarchical Representations
Mask R-CNN: instance segmentation
What is Common Sense?
Common Sense is the ability to fill in the blanks
How Much Information Does the Machine Need to
Training the Actor with Optimized Action Sequences
Augmenting Neural Nets with a Memory Module
Memory/Stack-Augmented Recurrent Nets
Entity Recurrent Neural Net
Energy-Based Unsupervised Learning
Seven Strategies to Shape the Energy Function
constant volume of low energy Energy surface for PCA and K-means 1. build the machine so that the volume of low energy stuff is constant
use a regularizer that limits do the volume of space that has low energy Sparse coding, sparse auto-encoder, Predictive Sparse Decomposition
The Hard Part: Prediction Under Uncertainty Invariant prediction: The training samples are merely representatives of a whole set of possible outputs (eg, a manifold of outputs).
Video Prediction: predicting 5 frames
