All credit to my teammates, my team placed 22nd out of 4037 in the Quora Insincere Questions Classification. The key challenge is to weed out insincere questions on Quora, while keeping the training and inference time below the 4 GPU-hour limit.
I deserve no credit on this one, as my contribution was trivial. My attempts on the Character Embeddings never paid off as the gain in performance wasn’t worth the slow-down in training. Please refer to the nice write-up and the kernel by Ryan Chesler for our solution.
