Energy-Aware Deep Learning on Resource-Constrained Hardware

arXiv.org Artificial Intelligence

The use of deep learning (DL) on Internet of Things (IoT) and mobile devices offers numerous advantages over cloud-based processing. However, such devices face substantial energy constraints to prolong battery-life, or may even operate intermittently via energy-harvesting. Consequently, \textit{energy-aware} approaches for optimizing DL inference and training on such resource-constrained devices have garnered recent interest. We present an overview of such approaches, outlining their methodologies, implications for energy consumption and system-level efficiency, and their limitations in terms of supported network types, hardware platforms, and application scenarios. We hope our review offers a clear synthesis of the evolving energy-aware DL landscape and serves as a foundation for future research in energy-constrained computing.

Fast Convolution based on Winograd Minimum Filtering: Introduction and Development

arXiv.org Artificial Intelligence

Convolutional Neural Network (CNN) has been widely used in various fields and played an important role. Convolution operators are the fundamental component of convolutional neural networks, and it is also the most time-consuming part of network training and inference. In recent years, researchers have proposed several fast convolution algorithms including FFT and Winograd. Among them, Winograd convolution significantly reduces the multiplication operations in convolution, and it also takes up less memory space than FFT convolution. Therefore, Winograd convolution has quickly become the first choice for fast convolution implementation within a few years. At present, there is no systematic summary of the convolution algorithm. This article aims to fill this gap and provide detailed references for follow-up researchers. This article summarizes the development of Winograd convolution from the three aspects of algorithm expansion, algorithm optimization, implementation, and application, and finally makes a simple outlook on the possible future directions.


A Review of Recent Advances of Binary Neural Networks for Edge Computing

arXiv.org Artificial Intelligence

Abstract--Edge computing is promising to become one of the next hottest topics in artificial intelligence because it benefits various evolving domains such as real-time unmanned aerial systems, industrial applications, and the demand for privacy protection. This paper reviews recent advances on binary neural network (BNN) and 1-bit CNN technologies that are well suitable for front-end, edge-based computing. We introduce and summarize existing work and classify them based on gradient approximation, quantization, architecture, loss functions, optimization method, and binary neural architecture search. We also introduce applications in the areas of computer vision and speech recognition and discuss future applications for edge computing. ITH the rapid development of information technology, cloud computing with centralized data processing cannot the performance of binary neural networks. To better review meet the needs of applications that require the processing these methods, we six aspects including gradient approximation, of massive amounts of data, nor can they be effectively used quantization, structural design, loss design, optimization, when privacy requires the data to remain at the source. Finally, we will also edge computing has become an alternative to handle the data review object detection, object tracking, and audio analysis from front-end or embedded devices.

DeepAISE -- An End-to-End Development and Deployment of a Recurrent Neural Survival Model for Early Prediction of Sepsis

arXiv.org Machine Learning

Abstract: Sepsis, a dysregulated immune system response to infection, is among the leading causes of morbidity, mortality, and cost overruns in the Intensive Care Unit (ICU). Ear ly prediction of sepsis can improve situational awareness amongst clinicians and facilitate timely, protective interventions. While the application of predictive analytics in ICU patients has shown early promising results, much of the work has been encumbe red by high false - alarm rates. Efforts to improve specificity have been limited by several factors, most notably the difficulty of labeling sepsis onset time and the low prevalence of septic - events in the ICU. We show that by coupling a clinical criterion for defining sepsis onset time with a treatment policy (e.g., initiation of antibiotics within one hour of meeting the criterion), one may rank the relative utility of various criteria through offline policy evaluation. Given the optimal criterion, DeepAISE automatically learns predictive features related to higher - order interactions and temporal patterns among clinic al risk factors that maximize the data likelihood of observed time to septic events. DeepAISE has been incorporated into a clinical workflow, which provides real - time hourly sepsis risk scores. A comparative study of four baseline models indicates that Dee pAISE produces the most accurate predictions (AUC 0.90 and 0.87) and the lowest false alarm rates (FAR 0.20 and 0.26) in two separate cohorts (internal and external, respectively), while simultaneously producing interpretable representations of the clinica l time series and risk factors. Introduction Sepsis is a syndromic, life - threatening condition that arises when the body's response to infection injures its own internal organs (1) . Though the condition lacks the same public notoriety as other conditions like heart attacks, 6% of all hospitalized patients in the U nited S tates carry a primary diagnosis of sepsis as compared to 2.5% for the latter (2) . When all hospital deaths are ultimately considered, nearly 35% are attributable to sepsis (2) . This condition stands in stark contrast to heart attacks which have a mortality rate of 2.7 - 9.6% and only cost the US $12.1 billion ann ually, roughly half of the cost of sepsis (3) .


AWS Looks to 'Demystify' Machine Learning

#artificialintelligence

Amazon Web Services used a big data conference in the backyard of some of its largest government customers to showcase its AI and machine learning tools that are helping to funnel ever-larger volumes of data into its storage and computing infrastructure. Making a pitch for better data management tools like metadata systems, AWS executives addressing a big data conference in Tysons Corner, Va., said the the public cloud giant aims to go beyond democratizing big data to "demystify" AI and machine learning. The combination of organized data and analytics will accelerate the building and deployment of machine learning models, many that currently never make it to production. Those that are deployed often require up to 18 months to roll out, noted Ben Snively, a solution architect at AWS (NASDAQ: AMZN). Open source tools for model development often advance a generation or two in the time it takes many enterprises to develop, train and launch a machine learning model, he added.


Yes, Uber has lost ridership to Lyft during this crisis

USATODAY - Tech Top Stories

Uber's discrimination investigation recommends dozens of reforms within their company walls. A sign marks a pick-up point for the Uber car service at LaGuardia Airport in New York on March 15, 2017. Travis Kalanick, the combative and embattled CEO of ride-hailing giant Uber, resigned June 20, 2017 under pressure from investors at a pivotal time for the company. SAN FRANCISCO -- In the tumultuous months leading up to Uber CEO and co-founder Travis Kalanick's resignation, the ride-hailing company lost U.S. market share and saw its brand image tarnished, most notably by a former engineer's blog post blasting the ride-hailing company for its sexist work environment. Among several surveys tracking the company's decline: one based on credit card spending, which found over the past two years, Uber's share of rides has dropped to 75% from 90%, according to TXN Solutions.
