Nettet5. jan. 2024 · Linear regression is a simple and common type of predictive analysis. Linear regression attempts to model the relationship between two (or more) variables by fitting a straight line to the data. Put simply, linear regression attempts to predict the value of one variable, based on the value of another (or multiple other variables). NettetAll right, now let's put together what we have learnt on backpropagation and apply it on a simple feedforward neural network (FNN) Let us assume the following simple FNN architecture and take note that we do not have bias here to keep things simple.
