Synopsis

cascade :: Num a => [[a] -> [a]] -> [a] -> [a]
gain :: Num a => a -> [a] -> [a]
bias :: Num a => a -> [a] -> [a]
adder :: Num a => [a] -> [a] -> [a]

Documentation

cascade Source #

Arguments

:: Num a
=> [[a] -> [a]]	f_n(x)
-> [a]	x[n]
-> [a]	y[n]

Cascade of functions, eg

cascade [ f1, f2, f3 ] x == (f3 . f2 . f1) x

Arguments

:: Num a
=> a	a
-> [a]	x[n]
-> [a]	y[n]

Gain node

y[n] = a * x[n]

Arguments

:: Num a
=> a	a
-> [a]	x[n]
-> [a]	y[n]

Bias node

y[n] = x[n] + a

Arguments

:: Num a
=> [a]	x[n]
-> [a]	y[n]
-> [a]	z[n]

Adder node

z[n] = x[n] + y[n]
