A Neuron in the Spotlight

Every neuron in an artificial neural network can be seen as a mathematical function which, as a rule, connects several inputs to an output. From the input values, the neuron generates an output value that is passed on to the next layer of neurons. The higher this value is, the more “active” the neuron becomes in the network. This is why we refer to so-called activation functions. At this station you can try out how different mathematical functions in the neuron affect the output.

 

Colors and Weights

Is it easier to read the black or the white letters on each background color? That’s what this network is being trained on. The input values are the percentages of the colors red, green, and blue (RGB spectrum) that make up the background colors. With every input, the system learns and we can watch how it changes the weights between the neurons in order to ultimately come up with a better result.
