Master’s student in Computer Science

Johns Hopkins University

About

I am Yi-Te Hsu, an M.S. Computer Science student at Johns Hopkins University. Currently, I am working on speech emotion conversion and detection with Prof. Archana Venkataraman. I was a machine learning engineer intern at Apple Inc. this summer, working on the machine translation projects.

Before coming to JHU, I conducted research on speech and signal processing with Dr. Yu Tsao at Academia Sinica. I mainly focused on model compression and acceleration for deep neural networks. I also collaborated with Prof. Frank Rudzicz at University of Toronto (UofT) and Vector Institute as a visiting researcher. I worked on healthcare projects for detecting pathological voice and identifying Alzheimer’s disease.

My interests include speech processing, natural language processing, AI, and ML. I am excited about applying these techniques to solve real-world problems.

I am looking for 2021 full-time opportunities!

Research Intern

Vector Institute; University of Toronto

Sep 2018 – Dec 2018 Toronto
  • Healthcare Project – Robust pathological voice detection system: Used bidirectional LSTM to develop an early detection system. Combined with an unsupervised domain adaptation method to solve the channel mismatch of different devices.
  • NLP Project – Detection of Alzheimer’s disease: Proposed a method to transfer Mandarin features to English ones with the corpus of a picture description task. Combined algorithms from different languages to achieves multi-language application.
 
 
 
 
 

Research Assistant

Academia Sinica

Feb 2018 – Jul 2019 Taipei
  • Quantization on deep neural network: Proposed a novel exponent-only floating-point quantized neural network (EOFP-QNN) to quantize the model. Achieved a 4x compression rate.
  • Acceleration on a compressed DNN: Proposed IA-Net, which can simultaneously compress the model size and accelerate the inference process by replacing the floating-point multiplier with an integer adder without performance degradation.
  • Bio-signal processing: Cooperated with the otolaryngologist and speech therapist at Far Eastern Memorial Hospital in Taiwan. Combined deep learning and machine learning techniques to develop the disease classification system by the patients’ voice. Taught electronic engineering and researched semiconductor physics.
