What is a “kernel” in this context? It doesn’t seem to be related to the OS kernel but some kind of graphics kernel? Whatever that is…
In the context of machine learning, usually a list of numbers that is arranged in a certain way, and is used for mathematical operation. You can think of it as a transfer/transform “function” that takes data as input, and spits out the representation of said data in some other way (that we usually don’t know until the training is finished and we analyze the result)
The weights for the neural network or the embeddings?
No. Normally the kernel doesn’t get updated in the network during training. They are called hyper-parameters. They do affect training, but they are not updated by the training algorithm
