Breaking The 1M RAID5 Write IOPS Barrier


In today’s data-centric age, enormous amounts of data are generated, stored and processed at an unprecedented rate. Businesses are utilizing this data to make better decisions, drive greater efficiencies, develop more desirable products, improve profitability and ultimately increase user satisfaction. To continue deriving a high degree of value from a rapidly-expanding data flow, today’s en... » read more

Nanophotonic Sensor Implants With 3D Hybrid Periodic-Amorphous Photonic Crystals For Wide-Angle Monitoring Of Long-Term In-Vivo Intraocular Pressure


In this work, we have developed a nanophotonic-based optomechnical device and reported the smallest intraocular pressure (IOP) implant (Dia: 500 um, Thick: 200 um) that can be placed in any area under the cornea into the anterior chamber without touching the endothelium. The sensor is made of only flexible biocompatible silicone/polydimethylsiloxane (PDMS) and structured as 3D hybrid photonic c... » read more

Modeling Analytics for Computational Storage


This paper discusses the expected performance benefits of offloading some important basic database operations — namely Scan, Filter and Project — to computational storage. We evaluate the performance estimate model using TPC-DS workload and two database engines running on Hadoop clusters: SPARK- SQL and Presto. This paper is organized as follows: after covering previous computational sto... » read more

DeepGBASS: Deep Guided Boundary-Aware Semantic Segmentation


Image semantic segmentation is ubiquitously used in scene understanding applications, such as AI Camera, which require high accuracy and efficiency. Deep learning has significantly advanced the state-of-the-art in semantic segmentation. However, many of recent semantic segmentation works only consider class accuracy and ignore the accuracies at the boundaries between semantic classes. To improv... » read more

As datacenter storage in- frastructures and technologies evolve, the need for speed and flexibility in the storage system becomes evident. NVMe is at the forefront of these advancements. Weka is a software defined storage system that is designed to meet the needs of today’s I/O intensive workloads. It... » read more

Multiexpert Adversarial Regularization For Robust And Data-Efficient Deep Supervised Learning


Deep neural networks (DNNs) can achieve high accuracy when there is abundant training data that has the same distribution as the test data. In practical applications, data deficiency is often a concern. For classification tasks, the lack of enough labeled images in the training set often results in overfitting. Another issue is the mismatch between the training and the test domains, which resul... » read more
