This chapter starts with a brief historical introduction to neural networks and the basic
perceptron, basically a neural network without hidden layers. We also discuss the
multilayer perceptron and training with gradient decent.
The historical t
In the previous learning problems we had training examples with feature vectors x
and labels y. In this chapter we discuss unsupervised learning problems in which no
labels are given. Training on unlabeled examples restricts the ty
Regression and maximum likelihood
We have so far given an overview of supervised learning where we propose a model
in form of a parameterized function and where we then learned the model parameters from example data. We have discussed this with a simple
