DELTA Joins LF AI & Data as New Incubation Project

By June 17, 2021No Comments

LF AI & Data Foundation—the organization building an ecosystem to sustain open source innovation in artificial intelligence (AI)and Data open source projects, today is announcing DELTA as its latest Incubation Project. 

DELTA is a deep learning based end-to-end natural language and speech processing platform. It aims to provide easy and fast experiences for using, deploying, and developing natural language processing (NLP) and speech models for both academia and industry use cases. DELTA is mainly implemented using TensorFlow and Python 3. It was released and open sourced by DiDi Global.

Dr. Ibrahim Haddad, Executive Director of LF AI & Data, said: “We are excited to welcome DELTA to LF AI & Data and help it thrive in a neutral, vendor-free environment under an open governance model. We look forward to help the project grow its community of users and contributors, enable collaboration and integration opportunities  with other hosted projects to drive innovation open source AI technologies.” 

DELTA has been used for developing several state-of-the-art algorithms for publications and delivering real production to serve millions of users. It helps you to train, develop, and deploy NLP and/or speech models, featuring:

  • Easy-to-use
    • One command to train NLP and speech models, including:
      • NLP: text classification, named entity recognition, question and answering, text summarization, etc
      • Speech: speech recognition, speaker verification, emotion recognition, etc
    • Use configuration files to easily tune parameters and network structures
  • Easy-to-deploy
    • What you see in training is what you get in serving: all data processing and features extraction are integrated into a model graph
    • Uniform I/O interfaces and no changes for new models
  • Easy-to-develop
    • Easily build state-of-the-art models using modularized components
    • All modules are reliable and fully-tested

Yunbo Wang, co-creator of DELTA, said: “ NLP and voice technology have been widely applied throughout DiDi’s business. For instance, Didi has built an intelligent customer service system based on AI to assist the efficiency of human customer service and reduce repetitive effort. Based on voice recognition and natural language understanding, DiDi has built a voice assistant function for drivers and applied it to the contact-free ride-hailing services in Japan and Australia. In the future, DiDi will continue to actively promote the opening of related capabilities. Through one-stop natural language processing tools and platforms, DiDi will help its industrial partners realize better AI application landing”. 

LF AI & Data supports projects via a wide range of services, and the first step is joining as an Incubation Project.  LF AI & Data will support the neutral open governance for DELTA to help foster the growth of the project. Check out the Documentation to start working with DELTA today. Learn more about DELTA on their GitHub and be sure to join the DELTA-Announce and DELTA-Technical-Discuss mail lists to join the community and stay connected on the latest updates. 

A warm welcome to DELTA! We look forward to the project’s continued growth and success as part of the LF AI & Data Foundation. To learn about how to host an open source project with us, visit the LF AI & Data website.
