Lesson 1 In-Class Discussion

Is there then a logic to how many layers you need to add in a CNN?

So a filter in the image case (which has three channels) could be a tensor? E.g. a 3 x 3 x 3 tensor?

Sorry, we were expecting the forums to be working.

yes :slight_smile:

Since like a minute ago things seem to work in forum

How do you visualise the convolutions (like in the Zeiler paper)?

It is a research question. In general which architecture to use it is a big research question.

Yes, it is

Yeah, not sure what changed, but things seem to be running smooth on the forum now.

With the 3 most important tools and jupityr being 3rd. What are the first two?

It is not straight forward to explain.

Seems like they used CNN to assess board positions.
See a paper in Nature.
"We pass in the board position as a 19×19 image and use convolutional layers to construct a representation of the position. "

@zaoyang If I’m not wrong, AlphaGo uses CNN in its primary stage to get raw images of board positions which then in is fed into its deep RL and MCTS to predict best move.

What do you actually need? Since you have access to forums.

Here is the full list of the report Jeremy was talking about.
