KDD 2022 Workshop on First Content Understanding and Generation for e-Commerce2022Slate-level recommendation is widely adopted in online services including e-commerce, video streaming and news services. Customers may observe a set of recommended items and interact with the content accordingly. Due to the combinatorial characteristics of slate level recommendation, various current ranking models are still aiming to optimize item level scores, instead of the slate level score. One key

USENIX ATC 20222022Amazon DynamoDB is a NoSQL cloud database service that provides consistent performance at any scale. Hundreds of thousands of customers rely on DynamoDB for its fundamental properties: consistent performance, availability, durability, and a fully managed serverless experience. In 2021, during the 66-hour Amazon Prime Day shopping event, Amazon systems - including Alexa, the Amazon.com sites, and Amazon

APSys Workshop on Systems2022Convolutional Neural Networks (CNNs) are widely used in real world applications, e.g, computer vision. Winograd based convolution are usually applied due to its low computation complexity. For the underling hardware, ARM many-core CPUs, by their price performance, are favored by cloud providers like Amazon Web Services (AWS). However, existing Winograd convolution implementations for ARM architecture are

RLDM 2022 Workshop2022We study task-agnostic continual reinforcement learning (TACRL) in which standard RL challenges are compounded with partial observability stemming from ask agnosticism, as well as additional difficulties of continual learning (CL), i.e., learning on a non-stationary sequence of tasks. Here we compare TACRL methods with their soft upper bounds prescribed by previous literature: multi-task learning (MTL)

TSD 20222022We propose a novel approach for semi-supervised learning (SSL) designed to overcome distribution shifts between training and real-world data arising in the keyword spotting (KWS) task. Shifts from training data distribution are a key challenge for real-world KWS tasks: when a new model is deployed on device, the gating of the accepted data undergoes a shift in distribution, making the problem of timely
