2015

We present a novel fine-tuning algorithm in a deep hybrid architecture for semisupervised text classification.

BBookX

2016

We describe BBookX, a web-based tool that uses a human-computing approach to facilitate the creation of open source textbooks. The goal of BBookX is to create a system that can search various Open Educational Resource …

Lifelong Neural Predictive Coding: Sparsity Yields Less Forgetting when Learning Cumulatively.

2019 · arXiv (Cornell University)

In lifelong learning systems, especially those based on artificial neural networks, one of the biggest obstacles is the severe inability to retain old knowledge as new information is encountered. This phenomenon is known as catastrophic …

Recovering Concept Prerequisite Relations from University Course Dependencies

2017 · Proceedings of the AAAI Conference on Artificial Intelligence

Prerequisite relations among concepts play an important role in many educational applications such as intelligent tutoring system and curriculum planning. With the increasing amount of educational data available, automatic discovery of concept prerequisite relations has …
