hypothesis-gufunc is an extension to hypothesis to aid in unit testing broadcasting and matrix input numpy/torch functions.
We develop a new measure called Loss Change Allocation (LCA) to better understand the training process. LCA measures how much each parameter helps decrease (or increase) the loss at every iteration. It is able to reveal broader patterns such as how training is very noisy, some layers hurt, and micro-learning is synchronized across layers.
Ludwig 0.2 is released with a host of new functionalities and features. The major ones are the integration with Comet.ml, the addition of BERT among text encoders, the implementation of audio/ speech, H3 (geospatial) and date (temporal) features, substantial improvements on the visualization API, and the inclusion of a serving functionality.
Uber AI Labs releases EvoGrad, a library for catalyzing gradient-based evolution research, and Evolvability ES, a new meta-learning algorithm enabled by this library.
Plato Research Dialogue System is a platform for building, training, and deploying conversational AI agents that allows us to conduct state of the art research in conversational AI and quickly create prototypes and demonstration systems, as well as facilitate conversational data collection.
Uber builds upon the Lottery Ticket Hypothesis by proposing explanations behind these mechanisms and deriving a surprising by-product: the Supermask.
Uber's Chief Scientist announces the launch of the Uber Research Publications Site, a portal for showcasing our contributions to the research community.
Uber scientists demonstrate how to train time-to-event models from censored data using the Pyro probabilistic programming language.
Uber hosted the first-ever Uber Science Symposium, a full-day event of presentations and conversations with stellar speakers and attendees, focusing on reinforcement learning, natural language processing and conversational AI, deep learning and deep learning infrastructure.
Our world-class team at Uber AI Labs pursues fundamental research in machine learning and connects cutting-edge advances to the broader business. Machine learning is essential to our business, and we are therefore fully committed to the pursuit of fundamental advances and vigorous engagement with the broader machine learning community.
Cameras provide a unique insight into the complex world Uber operates in. Our mission is to drive product differentiation and business efficiencies at Uber using visual data. We work together with product teams to develop state of the art computer vision and machine learning solutions.
Our mission is to make all Uber interactions as natural as talking to a friend! We deliver cutting-edge Conversational AI solutions to product teams across Uber, working with other AI teams and business units.
We believe sensors tell a story. Our goal is to leverage sensors as a source of truth and develop algorithms to solve our users' top pain points. The team has improved features like crash detection, enhanced location accuracy innovations, and even sent phone mounts to drivers for safer driving.
