6 Activation functions
7 Activation functions Traditionally used
8 Activation functions Currently most widely used. Empirically easier to train and results in sparse networks. Nair and Hinton: Rectified linear units improve restricted Boltzmann machines ICLM 10, (2010) Glorot, Bordes and Bengio: Deep sparse rectifier neural networks. PMLR 15: (2011)

15 A decision boundary perspective on learning Initial random weights
16 A decision boundary perspective on learning Present a training instance / adjust the weights
17 A decision boundary perspective on learning Present a training instance / adjust the weights
18 A decision boundary perspective on learning Present a training instance / adjust the weights
19 A decision boundary perspective on learning Present a training instance / adjust the weights
20 A decision boundary perspective on learning Eventually.
21 Nonlinear versus linear models NNs use nonlinear f(x) so they can draw complex boundaries, but keep the data unchanged Kernel methods only draw straight lines, but transform the data first in a way that makes it linearly separable
22 Universal Representation Theorem Networks with a single hidden layer can represent any function F(x) with arbitrary precision in the large hidden layer size limit However, that doesn t mean, networks with single hidden layers are efficient in representing arbitrary functions. For many datasets, deep networks can represent the function F(x) even with narrow layers.
23 What does a neural network learn?
24 Feature detectors
25 What is this unit doing?
26 Hidden layer units become self-organized feature detectors strong +ve weight low/zero weight 63
27 what does this unit detect? strong +ve weight low/zero weight 63
28 what does this unit detect? strong +ve weight low/zero weight it will send strong signal for a horizontal line in the top row, ignoring everywhere else 63
29 what does this unit detect? strong +ve weight low/zero weight 63
30 what does this unit detect? strong +ve weight low/zero weight Strong signal for a dark area in the top left corner 63
31 What features might you expect a good NN to learn, when trained with data like this?
32 Horizontal lines 1 63
33 Horizontal lines 1 63
34 Small circles 1 63
35 Small circles 1 But what about position invariance? Our example unit detectors were tied to specific parts of the image
36 Deep Networks
37 successive layers can detect higher-level features detect lines in Specific positions etc Higher level detetors ( horizontal line, RHS vertical lune upper loop, etc v etc
38 successive layers can detect higher-level features detect lines in Specific positions etc Higher level detetors ( horizontal line, RHS vertical lune upper loop, etc v etc What does this unit detect?
39 So: multiple layers make sense
40 So: multiple layers make sense Multiple layers are also found in the brain, e.g. visual cortex
41 But: until recently deep networks could not be efficiently trained
42
43 Convolutional Neural Networks
44
45 Convolutional Kernel / Filter Apply convolutions
46
47 Convolutional filters perform image processing
48 Example: filters in face recognition
49 MNIST dataset
50 Misclassified examples
