In ICLR. The paper presents a platform where students provide their logic to coding problems in their native language in plain text, which is then converted to python code using natural language processing techniques. The current platform can successfully identify and convert conditional statements in the Kannada language into python code. Treating this as a language task and drawing inspiration from ULMFiT, this was my basic approach: 1. (2017). The default speeds for the models during training on an NVIDIA Quadro GP100: The default QRNN models can be far faster than the cuDNN LSTM model, with the speed-ups depending on how much of a bottleneck the RNN is. The majority of the model time above is now spent in softmax or optimization overhead (see PyTorch QRNN discussion on speed ). All results are reported on the development set (to protect the test set). “Improving neural language models with a continuous cache”. Dropout Neural Net Model.
