A CNN that checks an image at several sizes in parallel.
Inception is like looking for your dog with binoculars and a magnifying glass at the same time. You catch the tiny wagging tail and the whole muddy mess.
It helps vision AI spot small details and big shapes without burning too much computer power. You meet it in classic image models like GoogLeNet.
CNN
Inception is a CNN design with parallel filters for many image sizes.
ImageNet
It became famous when GoogLeNet won on ImageNet.
ResNet
ResNet later pushed deep vision networks even further.
