Neural networks have been around for a long time, being developed in the 1960s as a way to simulate neural activity for the development of artificial intelligence systems. However, since then they have developed into a useful analytical tool often used in replace of, or in conjunction with, standard statistical models such as regression or classification as they can be used to predict or more a specific output. The main difference, and advantage, in this regard is that neural networks make no initial assumptions as to the form of the relationship or distribution that underlies the data, meaning they can be more flexible and capture non-standard and non-linear relationships between input and output variables, making them incredibly valuable in todays data rich environment.
In this sense, their use has took over the past decade or so, with the fall in costs and increase in ability of general computing power, the rise of large datasets allowing these models to be trained, and the development of frameworks such as TensforFlow and Keras that have allowed people with sufficient hardware (in some cases this is no longer even an requirement through cloud computing), the correct data and an understanding of a given coding language to implement them. This article therefore seeks to be provide a no code introduction to their architecture and how they work so that their implementation and benefits can be better understood.
Firstly, the way these models work is that there is an input layer, one or more hidden layers and an output layer, each of which are connected by layers of synaptic weights¹. The input layer (X) is used to take in scaled values of the input, usually within a standardised range of 0–1. The hidden layers (Z) are then used to define the relationship between the input and output using weights and activation functions. The output layer (Y) then transforms the results from the hidden layers into the predicted values, often also scaled to be within 0–1. The synaptic weights (W) connecting these layers are used in model training to determine the weights assigned to each input and prediction in order to get the best model fit. Visually, this is represented as:

_CNNs _are one of the state of the art, Artificial Neural Network design architecture, with one of the best deep learning tools in areas such as image recognition and classification. The Basic Principle behind the working of CNN is the idea of Convolution, producing filtered Feature Maps stacked over each other.
We’ll be using MNIST dataset which is readily available in different libraries. We’ll be importing our dataset from tensorflow library.
Code has been written in a generic template so as to do very minimal modifications and can run on many datasets with very little change.
Every CNN is made up of multiple layers, the three main types of layers are convolutional, pooling, and fully-connected.
The Conv layer is the core building block of a Convolutional Neural Network. The primary purpose of Conv layer is to extract features from the input image.
The convolutional layer can be thought of as the feature extractor of this network, it learns to find spatial features in an input image. This layer is produced by applying a series of many different image filters, also known as convolutional kernels, to an input image. These filters are very small grids of values that slide over an image, pixel-by-pixel, and produce a filtered output image that will be about the same size as the input image. Multiple kernels will produce multiple filtered, output images.
2. Pooling Layer
Pooling layer reduces the size of feature maps by using some functions to summarize sub-regions, such as taking the average or the maximum value. Pooling works by sliding a window across the input and feeding the content of the window to a pooling function.
3. Fully Connected Layer
The Fully Connected layer is configured exactly the way its name implies: it is fully connected with the output of the previous layer. A fully connected layer takes all neurons in the previous layer (be it fully connected, pooling, or convolutional) and connects it to every single neuron it has.

When discussing neural networks, most beginning textbooks create brain analogies. I can define the new neural networks simply as a mathematical function that translates a certain entry to the desired performance without going into brain analogies.
You may note that the weights W and biases b are the only variables in the equation above affecting the output of a given value. The strength of predictions naturally establishes the correct values for weights and biases. The weight and bias adjustment procedure of the input data is known as neural network training.
