A new evolution of computing is emerging around wearable technologies. Wearable computing has been a topic of research for years. However, we are beginning to see adoption by consumers and non-researchers due to advances ...

Reinforcement learning is a promising solution to the intelligent agent problem, namely, given the state of the world, which action should an agent take to maximize goal attainment. However, reinforcement learning algorithms ...

Natural language processing (NLP) technology has been applied in various domains, ranging from social media and digital humanities to public health. Unfortunately, the adoption of existing NLP techniques in these areas ...

In this thesis, we propose efficient algorithms and provide theoretical analysis through the angle of spectral methods for some important non-convex optimization problems in machine learning. Specifically, we focus on two ...

In this thesis we study various aspects of linear and semidefinite programs including their limitations in approximating various combinatorial optimization problems as well as applications of these paradigms in solving ...

With continued advances in science and technology, big graph (or network) data, such as World Wide Web, social networks, academic collaboration networks, transportation networks, telecommunication networks, biological ...
