Batched L2 Normalization Layer for Torch nn package
--[[
This layer expects an [n x d] Tensor and normalizes each
row to have unit L2 norm.
]]--
local L2Normalize, parent = torch.class('nn.L2Normalize', 'nn.Module')
function L2Normalize:__init()
parent.__init(self)
end

data chunking with overlapping windows! uses stride tricks so no data is copied; it just produces a view!
from __future__ import division
import numpy as np
from numpy.lib.stride_tricks import as_strided as ast
def chunk_data(data,window_size,overlap_size=0,flatten_inside_window=True):
assert data.ndim == 1 or data.ndim == 2
if data.ndim == 1:
data = data.reshape((-1,1))
# get the number of overlapping windows that fit into the data
