WebJan 10, 2024 · When you need to customize what fit () does, you should override the training step function of the Model class. This is the function that is called by fit () for every batch of data. You will then be able to call fit () as usual -- and it will be running your own learning algorithm. Note that this pattern does not prevent you from building ... WebOur goal is to find the values of A and B that best fit our data. First, we need to write a python function for the Gaussian function equation. The function should accept as inputs the independent varible (the x-values) and all the parameters that will be fit. # Define the Gaussian function def Gauss(x, A, B): y = A*np.exp(-1*B*x**2) return y.
