Webbz = θ 0 + θ 1 x 1 + θ 2 x 2 y p r o b = σ ( z) Where θ i are the paremeters learnt by the model, x 0 and x 1 are our two input features and σ ( z) is the sigmoid function. The output y p r o b can be interpreted as a probability, thus predicting y = 1 if y p r o b is above a certain threshold (usually 0.5). Under these circumstances, it ...
