2021 Amazon Research Day

About The Event

Amazon Research Days is a global engagement program created in 2018 to connect the scientific community at Amazon, industry leaders and external academic researchers in the field of machine learning around the world. We aim to create an opportunity for leading academic and industry researchers in machine learning to share ideas and foster collaboration through both formal and informal events at the conference.

When

17th & 18th Nov, 2021

ML@Amazon

Machine Learning, Big Data and related quantitative sciences have been strategic to Amazonfrom the early years. Amazon has been a pioneer in areas such as recommendation engines, ecommerce fraud detection and large-scale optimization of fulfillment center operations.

As Amazon has rapidly grown and diversified, the opportunity for applying machine learning has exploded. We have a very broad collection of practical problems where machine learning systems can dramatically improve the customer experience, reduce cost, and drive speed and automation. These include automated pricing and demand forecasting for hundreds of millions of products, predicting ad click probabilities, ranking product search results, matching products from multiple sources, classifying products into large taxonomies, information extraction and sentiment analysis for product reviews, voice recognition, natural language understanding, question answering and conversational systems.

Below are some of the problems we’re working on

Operational Efficiency 

Improve operational efficiency by reducing abuse, improving address quality and increasing payment/delivery success rates.

Customer Experience 

Improve customer experience by increasing search results and ads relevance, personalization, and providing conversational interfaces.

Seller Experience

Improve seller experience by providing automated tools (e.g. for forecasting product demand) that help them streamline their operations and grow their businesses on Amazon.

Catalog Quality

Improve catalog quality by identifying and correcting defects related to product attributes (e.g. title) and images.

ML Platforms 

Build ML platforms to speed up development and deployment of ML solutions.

ML Education 

Spread ML knowledge to empower the Amazon technical community.
