Learning to Execute LSTM RNN

Learning Approximate Solutions • Travelling Salesman Problem: NP-hard • Pointer Network can learn approximate solutions: O(n^2)

Learning to Learn with RNN • Deep Learning: hand-designed features learned features • This technique: hand-designed update rules learned update rules

SGD:

Momentum:

Adagrad:

Adadelta or RMSprop:

Adam:

One Shot Learning • Learning from a few examples • Matching Nets use attention and memory

a(x1,x2) is a attention kernel

Binarized Neural Networks BNN: neural networks with binary weights (i.e., 1 or -1) and activations at run-time 7 times faster
