Convolution Neural Network

Nowadys, Convolution Neural Network (CNN) is a hot topic for a research over unstructured data such as images, speech, time series and many more.
Two main reason for understanding CNN architeture is:

It can produce an modified signal which is better than original one.
It can learn through various filters with their respective weights and bias.

Actually what is convolution operation ?

To do convolution operation, both input and kernel signal should satisfy following properties:

A signal is linear if it have: a) scaling property and b) super-position property: Let the input and output signal can be written as:

y(t) = f(x(t)) .......... (1)

Equation (1) should follow scaling and super-position properties.

And a that signal should be Time Invarient : A time-independent signal can be expressed as

f(x(t-k)) = y(t-k) .......... (2)

Basic architecture of CNN:

The basic architecture of CNN include Conv-Relu_maxpool layer along with end attaching fully connected layer as shown below.

Each component of CNN is described as below:
