What power is needed to train a neural network?

Question

Neural networks

I myself have not yet learned to write neural networks, but in the future I plan to write a neural network of such a plan: There is a text, a picture, a video. And it is necessary to determine whether this text, picture, video belongs to this category (there will be one general category). As I understand it, on my laptop with an 8th generation core i5 processor, this cannot be done. What power should be for training this neural network and how long will it take to train it?

Answer 1

For your task, a video card of the middle-upper price segment is suitable.
For example, NVidia 1080
But to use an already trained neural network, more than an ordinary computer is suitable. Even the capabilities of the phone's processor will be enough.

Answer 2

Time depends on resources, the more resources, the less time will be needed.
The GPU is about an order of magnitude faster than the CPU.

Answer 3

Depends on the number of parameters in the network, which, in turn, depends on the number of layers and their sizes.
Simple networks for classifying an image or text can be trained on the CPU. I don't know about the video.
