Weights in Neural Networks

Question

We know weights inside neural networks affect the output value, and first, we set it for a random positive and negative numbers, and how is the 'learning' process, if the value are static?, or are the value can be changed? and how to do that automatically?

sorry i'm new to neural networks and deep learning,i'm really interested in data science and machine learning :D

The weights can be changed after a learning process. There are different algorithms to train your NN: back-propagation, genetic algorithm etc. There’s a lot of mathematical stuff you need to understand in Machine Learning.
Check out this youtube playlist and a channel in general:

I highly recommend it if you want to understand neural networks and be able to build it from scratch.
