About Me

I’m a second year PhD student of Computer Science & Engineering at Wright State University, Dayton OH. My research interests are broadly in data science, with a focus on deep learning, data semantics, and web systems modeling. I possess industry experience in neural and kernel learning methods for image processing and sequence prediction. My academic research studies ways to bias interior DNN mechanisms toward inherently explainable representations, given semantic information about relationships among input features. I have also applied Recurrent Neural Networks to reveal latent behavioral patterns in classes of automated traffic faced by web systems. I’m now actively seeking for a 2017 summer internship, and interested in both research related and programming related positions.

    A Soft Computing Prefetcher to Mitigate Cache Degradation by Web Robots

    The majority of requests seen by web servers and clouds are caused by web robots and IoT(Internet of things) agents. Prefetching web resources for caching and content management systems is a common technique to anticipate and pre-load the resources likely to be requested next for fast, low latency access. This project introduces a novel soft computing resource prefetcher, which marries a deep recurrent neural network(RNN) with a Bayesian network, to predict future requests made by web robots. Experiments with traffic logs from web servers across two universities demonstrate an improvement in precision and recall over a traditional dependency graph-based approach.



    Did you make the Wright Choice for your College?

    It is well known that U.S. university students often graduate with copious amounts of financial debt. The tuition rates for some colleges are often far above a reasonable threshold of being considered practical, which often limits many aspiring students' enrollment choices to educational institutions that seem more affordable. Even worse, students who do graduate often find themselves facing repayment obligations that far outweigh their potential income earnings. These notations collectively spark a number of questions.

  • Can we discover and explain groupings of colleges which exhibit similar characteristics?
  • Do higher tuitions colleges always provide students with higher average payment?
  • Can examining the relationship between features such as tuition costs and earnings after graduation help future students make more informed college decisions?
  • This is a final project for Machine Learning course, for more details please check the report here.

    Artistic Deep Nets

    This is just a demo project that I runned for my Deep Learning presentation in Wright State to show an application example of Deep Neural Network. The code is written by Justin Johnson and could be found online.
