    petuum inc.

    Machine Learning Intern

    • Designed and built the skeleton of NLP-pipeline project which serves as the infrastructure of machine learning solutions, including data packing schema, configuration-based programming, bridging the gap between distributed system team and machine learning teams • Built the CNN-biLSTM-CRF model and Bio-Bert model for name entity recognition (NER) and integrated it with the span-based semantic role labeling (SRL) model in NLP-pipeline framework

    Backend Engineer Intern

    • Designed the pixel-level classification model with CNN for map reconstruction from images containing million-level GPS point traces, automate the process to update the connectivity of road maps which is essential for in-car navigation • Implemented the evaluation algorithm for roadmap quality with topological exploration and visualized the running of missing road detection, providing a more robust metric which captures the geometry and topology of the roadmap quantitatively • Improved the F1 score of missing road detection from 0.4 to 0.7. The pipeline provided an end-to-end solution for online map refinement and unified the working flow of map refinement task for the whole GEO-road team

    Undergraduate Research Assistant

    Advisor: Prof. Ming Zhang • Representations of Heterogeneous Event Sequences for Clinical Prediction: built heterogeneous event sequence modeling framework for timely clinical prediction by adaptive segmentation and heterogeneous encoding; provided qualitative analysis of the experiments to validate the effectiveness of different modules and proposed improvement strategies • Dynamic Social Recommendation via Neural Attention Model: crawled movie rating and rater social network from douban website and organized a large dataset, then implemented recurrent neural network model for movie recommendation system • Proposed an attention-based deep learning pipeline for International Classification of Diseases (ICD) Coding of text medical documents, with character-aware language encoding, Tree-of-Sequences LSTM for syntactic extraction, attention mechanism, and adversarial learning. Achieved state-of-the-art accuracy and F-1 score on the MIMIC-III dataset. Published a first-author paper on arXiv and a second-author oral paper on ACL 2018.
