I can strongly recommend the Welch Labs videos on YouTube for getting a better intuitive explanation of this process. If you connect a network of these neurons together, you have a neural network, which propagates forward - from input output, via neurons which are connected to each other through synapses, like on the image to the left. The input is the sum of the three synapses connecting to the neuron (the three arrows at the left).Ī neural network illustration from Wikipedia. The circle below illustrates an artificial neuron. So what is a neural network? Let’s wait with the network part and start off with one single neuron.Ī neuron is like a function it takes a few inputs and calculates an output. In this post, I’ll give a few explanations and guide you to the resources I’ve used, in case you’re interested in doing this yourself.
While I didn’t manage to do it within a week, due to various reasons, I did get a basic understanding of it throughout the summer and autumn of 2015.īy basic understanding, I mean that I finally know how to code simple neural networks from scratch on my own. This time I’ve tried to learn neural networks. The first time consisted of learning how to do machine learning in a week. This is the second post in a series of me trying to learn something new over a short period of time.
