pymlp (Multilayer perceptron)

A part of master's life.

Prerequistes

• Python 3.x
• Numpy
• Matplotlib

Usage

• get_two_spiral_data

python3 mlp.py -d 1

• get_double_moon_data

python3 mlp.py -d 1

Configrue Nodes of hidden layer

It's two hidden layers, you can modify below values of code chunk for setting nodes what you want to in the network.

pymlp/mlp.py

Lines 74 to 82 in ab73f85

	''' initialize '''
	nvectors = c.shape[0] # row size of input pattern
	b_ninpdim = 2
	b_ninpdim_1 = b_ninpdim + 1
	i_nhid = 4
	i_nhid_1 = i_nhid + 1
	j_nhid = 2
	j_nhid_1 = j_nhid + 1
	k_noutdim = 1

for above sample means: 2-4-2-1

and here's hyperparameter

pymlp/mlp.py

Lines 106 to 113 in ab73f85

	lower_limit = 0.001
	iter_max = 5000
	eta = 0.01
	beta = 0.03
	_iter = 0
	iter_loop = 0
	error_avg = 10

Result

• Double moon
