• Designed practical models to predict words differently across Apps, constrained by a mobile phone, using Pytorch
• Research language model domain adaptation and proposed novel models based on RNNLM with different tradeoff
• With cost up to 3% of model size, on synthetic data for different corpus, decreased perplexity by 3-8%, increased hit3 accuracy by 1-3%; on real data for different Apps, reached significant improvement 7-12% at hit3.

• Prototyped next-generation input editor on Win10 with Deep Learning language model, using Python, TensorFlow
• Trained Japanese RNN language model, implemented Viterbi algorithm and optimized existing code
• Reached comparable word error rate with current product without optimization: 8.6% on literature and 5.5% on blog, built up multi-GPU training to boost training speed by 2x and Beam search to boost decoding speed by 20x-
• Built feedback classification system to increase the number of feedback reviewed, using Python, Scikit-learn
• Trained multiple binary classifiers on user feedback text with machine learning methods for the major types
• Saved manual efforts by 56% by filtering the major types out of raw feedback text with this system-
