As of December 2022, the channel has 4.89 million subscribers. The channel name and logo reference the color of Grant's right eye, which has blue-brown sectoral heterochromia.

What is BP neural network?

The back propagation (BP) neural network algorithm is a multi-layer feedforward network trained according to error back propagation algorithm and is one of the most widely applied neural network models.

What is backpropagation really doing Chapter 3 deep learning?

Backpropagation is just a way of propagating the total loss back into the neural network to know how much of the loss every node is responsible for, and subsequently updating the weights in a way that minimizes the loss by giving the nodes with higher error rates lower weights, and vice versa.

Where did Grant Sanderson go to college?

Grant Sanderson is the author of the YouTube channel 3Blue1Brown, which focuses on higher mathematics with a distinct visual perspective, and has over 3.5 million subscribers. Sanderson graduated from Stanford University in 2015 having studied math and computer science.
