Title of Speech: Collaborative Neurodynamic Optimization Approaches to Nonnegative Matrix Factorization  

Abstract: Nonnegative matrix factorization (NMF) is an advanced method for nonnegative feature extraction, with widespread applications. However, the NMF solution often entails to solve a global optimization problem with a nonconvex objective function and a nonnegativity constraint. To tackle this challenging problem, I will present a collaborative neurodynamic optimization approach by employing a population of recurrent neural networks (RNNs) at the lower level and particle swarm optimization (PSO) with wavelet mutation at the upper level. The RNNs act as search agents carrying out precise constrained local searches according to their neurodynamic equations and initial conditions. The PSO algorithm coordinates and guides the RNNs with updated initial states toward global optimal solution(s). A wavelet mutation operator is added in the optimization to enhance PSO exploration capability. Through iterative interaction and improvement of the locally best solutions of RNNs and global best positions of the whole population, the population-based neurodynamic systems is almost sure to achieve the global optimality for the NMF problem. The convergence of the group best state to the global optimal solution with probability one is proven. The experimental results substantiate the efficacy and superiority of the collaborative neurodynamic optimization approach to bound-constrained global optimization with several benchmark nonconvex functions and NMF-based clustering with benchmark datasets in comparison to the state-of-the-art algorithms.

Title of Speech: Reinforcement Learning to Rank for Search Result Diversification 

Abstract: The goal of search result diversification is to construct a document ranking for satisfying as many different query subtopics as possible. Typically, the diverse ranking process can be formalized as greedy sequential document selection. At each position, the document that can provide the largest amount of additional information to the users is selected. Since the utility of a document depends on its preceding documents in search result diversification, constructing an optimal document ranking is NP-hard. The traditional greedy document selection usually leads to suboptimal solutions. In the talk, I will show that the problem can be alleviated with a Monte Carlo tree search (MCTS) enhanced Markov decision process (MDP) model. Specifically, the sequential document selection process is fit into an MDP. At each time step the greedy action is further improved through the exploratory tree search by MCTS. Reinforcement learning algorithm was developed to learn the model parameters. Empirical evaluation clearly indicated the effectiveness of the approach. The MCTS enhanced MDP can also be applied to variant applications, including sequence tagging, text matching etc.

Title of Speech: Wireless Data Acquisition in Big Data Era 

Abstract: Wireless sensor networks (WSNs) and Internet of Things (IoT) are fundamentally changing today’s practice of numerous scientific and engineering endeavors by enabling continuous monitoring and sensing of physical variables of interest at unprecedented high spatial densities over long-time durations. They have significantly impacted broad fields such as environmental sciences and engineering, ecosystems, natural hazards, precision agriculture, smart building, and smart city. We focus on outdoor large-scale WSNs/IoT that are deployed in harsh environments, such as mountainous areas, hilly watersheds, and forests, which present great challenges in WSN/IoT data acquisition, because of the severe resource constraints (e.g., battery power, bandwidth, memory size, and CPU capacity) of tiny sensor nodes. In this talk, I will share my group’s work on wireless data acquisition and present a novel compressed sensing approach. Our approach can recover the sensing data at the WSN sink with high fidelity when very few data packets are collected, leading to a significant reduction of the network transmissions and thus an extension of the WSN/IoT lifetime. I will also present and discuss our results on data acquisition from a real-world environmental WSN testbed deployed in Pennsylvania, USA.

Title of Speech: High Performance Computing Revisited for Big Data Applications  

Abstract: The increasingly important data-intensive scientific discovery presents a critical question to the high performance computing (HPC) community - how to efficiently support these growing scientific big data applications with HPC systems that are traditionally designed for big compute applications? The conventional HPC systems are computing-centric and designed for computation-intensive applications. Scientific big data applications have different characteristics compared to big compute applications. These scientific applications, however, will still largely rely on HPC systems to be solved. In this talk, we try to answer this question with a rethinking of HPC system architecture. We study and analyze a decoupled HPC system architecture for data-intensive scientific applications. The fundamental idea is to decouple conventional compute nodes and dynamically provision as data processing nodes that focus on data processing capability. We present studies and analyses for such decoupled HPC system architecture. Its data-centric model and architecture can have an impact in designing and developing future HPC systems for big data applications.
