Convexity, Sparsity, Nullity and all that... in Machine Learning
Abstract of Talk: High dimensional data exhibit distinct properties compared to its low dimensional counterpart; this causes a common performance decrease and a formidable computational cost increase of traditional approaches. Novel methodologies are therefore needed to characterize data in high dimensional spaces.
Considering the parsimonious degrees of freedom of high dimensional data compared to its dimensionality, we study the union-of-subspaces (UoS) model, as a generalization of the linear subspace model. The UoS model preserves the simplicity of the linear subspace model, and enjoys the additional ability to address nonlinear data. We show a sufficient condition to use l1 minimization to reveal the underlying UoS structure, and further propose a bi-sparsity model (RoSure) as an effective algorithm, to recover the given data characterized by the UoS model from errors/corruptions.
As an interesting twist on the related problem of Dictionary Learning Problem, we discuss the sparse null space problem (SNS). Based on linear equality constraint, it first appeared in 1986 and has since inspired results, such as sparse basis pursuit, we investigate its relation to the analysis dictionary learning problem, and show that the SNS problem plays a central role, and may naturally be exploited to solve dictionary learning problems. Substantiating examples are provided, and the application and performance of these approaches are demonstrated on a wide range of problems, such as face clustering and video segmentation.

Technology Considerations in Computer Architecture
Abstract of Talk: Good engineering practice uses the characteristics of existing technologies to optimize implementation. Often, this will mean that design techniques optimal in a previous generation prove impractical or even unusable when a new technology becomes dominant. This rule is all too often forgotten, which we will demonstrate in two problems of computer design: Field-Programmable Gate Arrays (FPGA) and hardware prefetchers (providing the ability to fetch data early in anticipation of the need). FPGAs are extremely useful in mobile embedded systems where computing power and energy considerations are major concerns. Partial reconfiguration is often used to reduce power consumption when parts of the array are inactive, albeit at the cost of high energy overhead due to the large cost of transferring configuration information. Our study reveals that partial reconfiguration accelerates execution and reduces overall energy consumption by half. Second, we will demonstrate how increased transistor integration allows hardware prefetching to improve both energy-efficiency and performance.

IoT/Cloud-Based Smart Nanogrod™ for Sustainable Rural Development
Abstract of Talk: The socioeconomic development of India’s marginalized rural and agricultural communities, needs interventions to move them up the value chain by addressing three key areas of education, employment and energy. Access to sustainable, reliable, and affordable energy, creation of ‘micro-enterprise zones (MEZs)’ business models and development of locally relevant skills play key roles. These, in turn, reduce the pressure on agriculture and land, and lead to triple bottom-line impact. SunMoksha has developed a holistic solution, ‘Smart NanoPower’, for sustainable, scalable, rural socioeconomic development. The key ‘technical intervention’ of NanoPower is the ‘Smart Nanogrid’ - a comprehensive IoT-on-Cloud solution to remotely manage the entire operations of the micro-grid, including hybrid renewable energy, remote monitoring, management and maintenance, demand-supply management in a mini/micro/nano-grid, billing and payment, knowledge sharing and training. A dynamic management of supply and demand is the key differentiator. It dynamically manages demands to meet supply constraints and vice versa. Additionally, it provides complete solution for management energy, water, agriculture and environment! A key differentiator of Nanogrid is making data available to experts in real time for a timely intervention; thus bridging the skills gaps and providing a platform for sustainable, scalable business models. The ‘social interventions’ of ‘NanoPower’ include viable business models for sustainability and scalability, and skill development for bridging the skills gaps and creating entrepreneurial capacity. Our model has been successfully demonstrated in Chhotkei village in Odisha, and endorsed by MNRE, Power Minister, ISGF, ADB, OREDA and won Smart Village Award.
