What is Artificial Neural Network ?

Now let me ask you a thing , In which field we are better than the computers . Not that love and anger things 🤣 . We humans are good at recognising the objects or some image whereas the computer is best at doing the algorithm work .

So now if I ask a machine that which among these is 7 or 9 or 1 or 3

Here the neural network come into the play

Neural Networks create their own rules on the basis of dataset . Like in this case if we give this dataset to the machine and ask after that in our own handwritting than the computer would be able to answer it . because we have provided him/her about different types of numbers . Now from where we would get these datasets ?

Modified National Institute of Standards and Technology dataset

The MNIST dataset is an acronym that stands for the Modified National Institute of Standards and Technology dataset. It is a dataset of 60,000 small square 28×28 pixel grayscale images of handwritten single digits between 0 and 9.

It have different fields datasets too. Like for fashion , cars , animals and many more !!

So as when studying for human body we begin it with cells , for neural network we have perceptron here


These are the building blocks of Machine Learning. A neural network unit that does certain computations to detect features or business intelligence in the input data


This is how a perceptron works ! Firstly we gave multiple inputs which would be binary ( 0 or 1 / True or False ) and the weight of them which are represented as " w " which shows the importance of that in the result !

y -> a function that would do everything to find out this result !!

We have an output .. This was from the surface . How it looks and how it goes .

Now ,


Now here is something we discussed above but a new word came here , threshold ...... What's that ? It's the requirement of the user from the output , like if we want a black shirt and a full shirt , then for black it would be 1 and for that too it would be1 Simply the required weight in output is threshold !

So for each input we do input[0] * weight [0] ...... till mth input and add that up if that is > threshold then output is 1 otherwise 0 !
