WebbIn this module, a neural network is made up of multiple layers — hence the name multi-layer perceptron! You need to specify these layers by instantiating one of two types of specifications: sknn.mlp.Layer: A standard feed-forward layer that can use linear or non-linear activations. WebbIn a vector form, the perceptron implements. h ( x) = sign ( ω T x) Sign function. sgn ( x) = { 1, if x < 0 0, if x = 0 − 1, if x > 0. Hyperplane. Separates a D-dimensional space into two half-spaces. Defined by an outward pointing normal vector ω. ω is orthogonal to any vector lying on the hyperplane.
