slowly, I’m going on with the solution of the Advent of Code 2022 puzzles in pure TensorFlow.
This time, the article is dedicated to a single solution because things are getting more complicated Check it out!
A deep dive into the tf.strings module, regexp, and some hints for a different solution using variables with undefined shapes!
Moreover, I tried to explain a little bit about how to use tf.meshgrid for creating indexes when working with sparse updates - or at least, I demonstrated how to use it in the hope of sharing knowledge about this way of working with sparse tensors.
Any resharing and feedback are appreciated
