[TVM Discuss] [Questions] Question about touched memory as a feature
for ML cost model
I have been studying the features extracted from the low-level AST in the paper:
"Learning to Optimize Tensor Programs"
https://arxiv.org/abs/1805.08166
I came across the example below,
![image|469x162](upload://1Nwo3tRquN16jTKyfcot5zSU0s5.png)
but I am having trouble understanding the numbers | x | 8 | 8 | 64 |. Since I do not see "x" indexing "A". The same applies to | y | 64 | 64 | 64 |, since I do not see "y" indexing matrix "B"
I would really appreciate it if someone could explain this to me in more detail, and in general, the concept of touched memory
