Hello it is my first time working with tensorflow, i try to adapt the example here TensorFlow-Examples to use this code for regression problems with boston database. Basically, i only change the cost function ,the database, the inputs number, and the target number but when i run the MPL...
A multilayer perceptron is a logistic regressor where instead of feeding the input to the logistic regression you insert a intermediate layer, called the hidden layer, that has a nonlinear activation function (usually tanh or sigmoid) . One can use many such hidden layers making the architecture ...
