Ambarish Goswami --- Even after more than 40 years of intense research balance control remains an active topic in humanoid robotics. Although balance maintenance skills of robots have improved significantly during this time, there is constant reminder in the form of the highly-skilled human balance which indicates to us how much…

Haiyan Qiao --- Learning in the real world occurs when an agent, which perceives its current state and takes actions, interacts with the environment, which in return provides a positive or negative feedback. Research of reinforcement learning studies such processes and attempts to find policies that map states of the world to the…

Lise Getoor --- In today's world, networks abound; there are social networks, communication networks, computer networks, financial transaction networks, gene regulatory networks, disease transmission networks, ecological food networks, sensor networks and more. Observational data describing these networks is often easy to come by…

Adam Meyerson --- We will present a new algorithm for the streaming k-means problem. K-Means is a popular formalization for data clustering, which has many applications in the analysis of large databases. Unfortunately, optimizing the k-means objective is NP-Complete, and as data sets grow larger and larger, even approximation…

Tao Xie --- Highly reliable, high performance and energy-efficient storage systems are essential for mobile data-intensive applications such as remote surgery and mobile data center. Existing mobile storage systems generally consist of an array of independent small form factor hard disks connected to a host by a storage interface…

David Atienza Alonso --- Continuous technical advances in manufacturing technologies are fueling the trend towards more powerful 3D Multi-Processor System-on-Chip (MPSoC) designs. However, 3D stacking originates larger heat densities beyond the standard 2D MPSoCs due to the higher power density resulting from the placement of…

Robert E. Tarjan --- Deletion in a balanced search tree is a problematic operation: rebalancing on deletion has more cases than rebalancing on insertion, and it is easy to get wrong.  We describe a way to maintain search trees so that rebalancing occurs only on insertion, not on deletion, but the tree depth remains logarithmic in…

Joseph Teran --- We present a highly efficient numerical solver for the Poisson equation on irregular voxelized domains supporting an arbitrary mix of Neumann and Dirichlet boundary conditions. Our approach employs a multigrid cycle as a preconditioner for the conjugate gradient method, which enables the use of a lightweight,…

Francesco Regazzoni --- Security is a fundamental feature for nowadays embedded systems, however, satisfying this need is particularly challenging due to the advent side channel attack. These new, cheaper and faster attacks derive the secret key from the information leaked while data is being processed. In particular, power…

Robert Murray --- This talk will cover two technologies that can be effective at gleaning insights and knowledge from very large datasets: Mapreduce, and Machine Learning.   We'll introduce the basic concepts behind each technology.  We'll then talk about how the Google TV Ads project is using these technologies to help TV…
