Neural Modeling of Polynomial Image Interpolation

Artificial neural networks (ANNs) are efficient optimization tools that have emerged to simulate the methods of human thinking. These networks have certain structures based on neurons and activation functions. Researchers have shown that the human brain stores information in the form of patterns. ANNs are massively parallel networks designed to do the same task. They are used in modeling to save certain patterns in databases that are further used for pattern matching [37].

In addition, ANNs can be used as powerful tools for modeling general input–output relationships [37]. Applications of ANNs have been reported in areas such as control, telecommunications, remote ...

Julian F.

Head of Cybersecurity

I wanted to learn C and C++, but it didn't click for me until I picked up an O'Reilly book. When I went on the O’Reilly platform, I was astonished to find all the books there, plus live events and sandboxes so you could play around with the technology.

Addison B.

Field Engineer

I’ve been on the O’Reilly platform for more than eight years. I use a couple of learning platforms, but I'm on O'Reilly more than anybody else. When you're there, you start learning. I'm never disappointed.

Amir M.

Data Platform Tech Lead

I'm always learning. So when I got on to O'Reilly, I was like a kid in a candy store. There are playlists. There are answers. There's on-demand training. It's worth its weight in gold, in terms of what it allows me to do.
