Auto-encoder

Parameters initialization

- No. of hidden layers: h

- Input feature set: [x1, x2, x3, …, xn]

- Encoding-activation function: EAF

- Decoding-activation function: DAF

- Inputs weights: Wi

- Biasness values: bi

Encoding

- Compute encoded inputs f(w) by multiplying xn and Wi

- Compute biased inputs f(b) by adding bI to the encoded inputs

- Compute f(x) using Eq. (1) by applying f(w) and f(b)

Decoding

- Compute decoded outputs f(w′) by multiplying xn and Wi

- Compute biased outputs f(b′) by adding bI to the decoded outputs

- Compute g(y) using Eq. (2) by applying f(w′) and f(b′)

Optimization

- Optimize the value of Eq. (5)
