However, some other examples of using whiteboards: Daily / Weekly stand ups or reviews with the teams; Project kick offs
Trained via deep reinforcement learning. The model was pretrained in semi-supervised fashion. It uses LSTMs to predict expected rewards of a large number of plans of actions (e.g "press W and A, then press W, then press W, then press W and A") and picks the one with the highest reward. Implementation done in python using the pytorch framework.
