In-Memory Hardware-Software Co-design for Image Processing
A substantial part of high energy consumption (> 60%) and large latency (> 90%) of conventional von-Neumann architectures can be attributed to the unavoidable data movement between the processor and main memory (DRAM). This is perhaps the major limiting factor for big data and machine learning applications whose usage is permeating into practically...

Explainable Design Space Exploration for Efficient Hardware/Software Codesigns
Computing system designers need to characterize the execution of applications on a computing system (e.g., on a processor) and they also need to improve the design (i.e., find better hardware/software configurations for the computing system such as one that produces more throughput at lower energy consumption). Existing mechanisms for computing systems’...

Learning Sparse Features for Self-Supervised Learning with Contrastive Dual Gating
The success of conventional supervised learning relies on large-scale labeled datasets to achieve high accuracy. However, annotating millions of data samples is labor-intensive and time-consuming. This promotes self-supervised learning as an attractive solution with artificial labels being used instead of human-annotated ones for training. Contrastive...

Optimizing Solar Power using Array Topology Reconfiguration and Deep Neural Network
Photovoltaic (PV) energy systems have played a major part in meeting renewable energy requirements. However, power production from PV systems faces impediments such as partial shading due to environmental and man-made obstructions. Shading causes voltage and current mismatch losses that can significantly reduce the power supplied to the grid. Reconfiguring...

Detection and Classification of Faults in Photovoltaic Arrays Using a Graph-Based Classifier
In the last decade, new solar photovoltaic (PV) cell technologies have emerged for grid-connected systems. However, automatic fault detection and accurate diagnostics for PV array systems are still challenging problems. Even with over-current protection devices (OCPD), ground fault detection interrupters (GFDI), and smart monitoring devices (SMDs) with...

Connection Topology Optimization of Photovoltaic Arrays Using Neural Networks
The production of photovoltaic (PV) energy is affected by numerous external factors such as varying temperatures, soiling of PV panels, and partial shading which can significantly reduce power generated. Off-the-shelf PV arrays are typically connected in a series-parallel (SP) topology, featuring parallel-connected strings of series-connected panels....
