<e>Lets consider Information reduction</e>
<e>assume something is represented by one x and by one y value</e>
<e>so to describe one object, we require two variables</e>
<e>now we want to reduce this to only one variable</e>

<e>you can do this by fitting a function</e>
<e>you reduce two values #(x,y)# into one value #x# and some function #y(x)#</e>
<e>less accurate, but more understanding</e>

<e>Now lets do the same with a neuronal Network</e>
<e>Here we have one input and one output</e>
<e>so its basically just a way of encoding a function</e>
