Machine Learning – Artificial Neurons / Perceptrons (Part 2)

So then, time for part 2 of Perceptrons :D

Here im going to give a few examples of the algorithm working, then its onto the next part :)

Machine Learning – Artificial Neurons / Perceptrons (Part 1)

Quick Perceptron Example

Here we go… a Decision Boundary… again. Yes you may now kill me :)

Actually, this time it really isn't that bad, because a Perceptron literally IS a decision boundary. Lets take a look at a rounded decision boundary from KNN:

Machine Learning – More on Decision Boundaries

Okay, so as it turns out i forgot something… again! darn im getting good at this ¬.¬

On the post for K-Nearest Neighbour Part 2, I showed a Graph with a Decision Boundary. Well this is just one type of decision boundary. There are technically more but im going to show 3 of them here.

Machine Learning – K-Nearest Neighbour (Part 2)

Last Time

Last time we learnt about the algorithm that the K-Nearest Neighbour use’s, using Cats and Dogs, if you want more go here!:  Part 1

Machine Learning – K-Nearest Neighbour (Part 1)

Cats and Dogs

Lets take 2 example classes. Say we wanted to be able to recognise the difference between a Cat and a Dog, how would you do this?

Well, firstly we have to identify some features that can easily distinguish them both. Lets have a quick example of a cat and a dog – yeah, seriously :P

Computer Networks - An Introductory Overview

What is a computer network?

To a user - something that allows applications to talk to each other. They have an idea as to what the infrastructure should allow them to do. Email and web browsing should be reliable. Internet banking should also be secure. Internet radio, voice over IP and video streaming should have quality. With VoIP however you also want low latency (delay) too, as opposed to internet radio. The demands of the network depend on what type of application you want to run.

Cocoa Framework Summary

A summary by James Bedford.

Cocoa is a framework of tools used for software development written in Objective-C, featuring modular, object-oriented and visual design. It was originally called NextSTEP and was developed by the company NeXT. When NeXT merged with Apple in 1996, the framework NextSTEP was renamed Cocoa. However, it still remains that all objects within this framework begin with the prefix "NS", which helps to distinguished them and prevent accident errors.

This summary is work-in-progress (which will be periodically updated) and may contain mistakes. Please let me know if there are any issues, or if anything needs clarifying.
