what is artificial neural network and how does it work

As the name proposes, artificial neural networks are demonstrated on natural neural networks in the mind. The cerebrum is composed of cells called neurons, which convey messages to one another through associations known as neurotransmitters. Neurons communicate electrical signs to different neurons dependent on the signs they, at the end of the day, get from different neurons. An artificial neuron reproduces how a natural neuron acts by including the upsides of the sources of info it gets.
In case this is over some edge, it conveys its message to its yield, which is then gotten by different neurons. Nonetheless, a neuron doesn't need to treat every one of its contributions with equivalent weight. Every one of its bits of feedback can be changed by increasing it by some weighting factor. Say, whenever input A was twice pretty much as significant as info B, then, at that point input A would have a load of 2. Loads can likewise be negative if the worth of that information is immaterial.
