Any thoughts from the DOTA team on handling a world map which not bounded in size ? In my projects, the "world" size can change (unlike Go, Chess where the board size is fixed). Is the DoTA board size fixed? I guess the LTSM encodes the board history as seen by the agent. But this probably slows the learning. Some people suggested auto-encoder to compress the world, and then feed it to a regular CNN. Any comments would be welcome.
