Upcoming Colloquia

Modeling and Control for Robotic Assistants

Rogers 226

Ph.D. Candidate

University of Pennsylvania

Abstract

As advances are made in robotic hardware, the capacity of the complexity of tasks they are capable of performing also increases. One goal of modern robotics is to introduce robotic platforms that require very little augmentation of their environments to be effective and robust. Therefore the challenge for the Roboticist is to develop algorithms and control strategies that leverage knowledge of the task while retaining the ability to be adaptive, adjusting to perturbations in the environment and task assumptions.

These strategies will be discussed in the context of a wet-lab robotic assistant. Motivated by collaborations with a local pharmaceutical company, we will explore two relevant tasks. First, we will discuss a robot-assisted rapid experiment preparation system for research and development scientists. Second, we will discuss ongoing work for intelligent human-robot cooperative transport with limited communication. These tasks are the beginning of a suite of abilities for an assisting robotic platform that can be transferred to similar applications useful to a diverse set of end-users.

Wildbook - Photographic Censusing of Wildlife

Abstract

As the price of photography and video equipment drops while availability improves, visual data from the public is becoming the most abundant source of wildlife data.  However, curating this high volume of data from "citizen science" and social media poses new scalability challenges for both researchers and computer scientists alike.  This talk introduces the Wildbook platform -- an open-source web-based project (wildbook.org) -- that leverages a suite of deep learning tools to automatically process high volumes of image data for conservation.  The platform uses Convolutional Neural Networks (CNNs) on several computer vision tasks, including: image classification, bounding box regression, instance classification, class segmentation, and object of interest classification.  Our deep learning stack utilizes Theano and PyTorch on the NVIDIA's CUDA, CNMeM, and CuDNN deep learning stack and employs multiple Titan V GPUs for efficient processing.  Further, instance recognition allows Wildbook to individually identify individual animals through time using a pipeline of SIFT features to find distinctive patches, Approximate Nearest Neighbors to find visual neighbors, and LNBNN to associate and re-rank visual match correspondences.  A random forest pair-wise match verifier is then used to curate animal sightings for human-in-the-loop population curation.  Lastly, our computer vision pipeline works alongside an intelligent agent that can automatically ingest video data from YouTube using NLP and OCR with Azure Cognitive Services.   We present our conservation work for wildlife across the globe in the context of the latest advances in deep learning and how Wildbook is helping to convert wildlife conservation into a data-driven science.

Jason Parham received his B.S. in Computer Science / Mathematics from Pepperdine University in Malibu, CA in 2008 and holds a M.S. in Computer Science from RPI in Troy, NY.  Jason is finishing his Ph.D. as a candidate under the advising of Dr. Charles Stewart at RPI.  Jason’s Masters thesis was on the design and implementation of a citizen science-powered photographic censusing of the zebra and giraffe in the Nairobi National Park.  His current doctoral research focuses on animal detection and classification, using deep learning on wildlife imagery, to power automated photographic censusing.  Jason is a co-developer of Wildbook‘s Image Analysis components, which are used to monitor animal populations in conservancies around Kenya and which integrate with the Wildbook data management platform for a suite of species. Previously, Jason worked three years for Kitware, Inc. in Clifton Park on detecting vehicles and military aircraft in overhead satellite imagery.  Below are some select publications: - An Animal Detection Pipeline for Identification Lake Tahoe, CA.

Energy Efficient Computing in Nanoscale CMOS

Gaulke Distinguished Lecture
Friday, March 1, 2019 - 4:00pm to 4:50pm

Speaker Information

Vivek De
Intel Fellow
Director of Circuit Technology Research

Abstract

Future computing systems spanning exascale supercomputers to wearable devices demand orders of magnitude improvements in energy efficiency while providing desired performance. The system-on-chip (SoC) designs need to span a wide range of performance and power across diverse platforms and workloads. The designs must achieve robust near-threshold-voltage (NTV) operation in nanoscale CMOS  process while supporting a wide voltage-frequency operating range with  minimal impact on die cost. We will discuss circuit and design technologies to overcome the challenges posed by device parameter variations, supply noises, temperature excursions, aging-induced degradations, workload and activity changes, and reliability considerations. The major pillars of energy-efficient SoC designs are: (1) circuit/design optimizations for fine-grain multi-voltage & wide dynamic range, (2) fine-grain on-die power delivery & management, (3) dynamic adaptation & reconfiguration, (4) dynamic on-die error detection & correction, and (5) efficient interconnects.
