#019 CNN Transfer Learning Master Data Science
So if we are building a computer vision application rather than training a neural network from scratch we often make much faster progress if we download the network's weights. In other words someone else has already trained the network architecture and we can use and that to a new task that we are solving. The computer vision research community has posted lots of datasets on the internet like Imagenet or NS Coco or Pascal datasets. Many computer vision researchers have trained their algorithms on these datasets. Sometimes this training takes several weeks and might take many GPUs.
