COMP5329 Deep Learning Week 8 – Recurrent Neural Networks 1. Backpropagation through time (BPTT) in RNNs After the RNN outputs the prediction vector h(t), we compute the prediction error E(t) and use the Back Propagation Through time algorithm to compute the gradient (1) ∂E ∂W = T∑ t=1 ∂Et ∂W . The gradient is used
COMP5329 Deep Learning Week 2 – Multilayer Neural Networks 1. Perceptron Despite the fantastic name – Deep Learning, the field of neural networks is not new at all. Perceptron can be the foundations for neural networks in 1980s. It was developed to solve a binary classification problem. Figure 1. A Perceptron module. We consider the

COMP5329 Deep Learning Week 11 – Deep Learning Applications 1. R-CNN R-CNN is short for “Region-based Convolutional Neural Networks” [1]. The main idea is com- posed of two steps. First, using selective search, it identifies a manageable number of bounding- box object region candidates (“region of interest” or “RoI”). And then it extracts CNN features
