Yeah, you guessed it right, I will take an example to explain - how an Artificial Neural Network works. a classification .

CNN is mostly used for Image Data, whereas it is better to use ANN on structural data. And while in the Perceptron the neuron must have an activation function that imposes a threshold, like ReLU or sigmoid, neurons in a Multilayer Perceptron can use any arbitrary activation function. It is more of a practical swiss army knife tool to do the dirty work. But we always have to remember that the value of a neural network is completely dependent on the quality of its training. When Multilayer Perceptrons have a single-layer neural network they are
