Hands-On Artificial Intelligence for Cybersecurity

It's all about finding the right weight!

One of the differences in the approach between the statistical models and the AI algorithms is that the algorithms implement an optimization strategy based on the iteration. At each iteration, in fact, the algorithm tries to adjust its own estimate of the values, attributing to them a greater or lesser weight depending on the cost function that we must minimize. One of the aims of the algorithm is to identify precisely an optimal weight vector to be applied to the estimated values in order to obtain reliable future predictions on unknown future data.

To fully understand the power of AI algorithms applied to spam detection, we must first clarify the ideas on which tasks we should perform a spam filter. ...
