Rise of the MachinesJack Concanon

“A Field of study that gives computers the

ability to learn without being explicitly programmed

- Arthur Samuel

  “A computer program is said to learn from

experience E with respect to some class of tasks T and performance measure P, if its performance at

tasks in T, as measured by P, improves with experience E

- Tom M. Mitchell

Can Machines Think?

Can machines do what we do?

Can they pretend?

How much help do they need?

Why Now?

Supervised Learning Requires labelled training

examples Function approximation Based on an input vector

you should receive an expected output

Linear regression is the simplest

Line of best fit is a valid tool for prediction

Unsupervised Learning

Unclassified data

Finding hidden structures

Clustering

Data mining

Linear Regression Example

Neural Networks

Neural Network Visualisation

Example – Cat or Hat?
