Tesseract
Tesseract is an optical character recognition (OCR) engine originally developed by Hewlett Packard as a proprietary technology in the 1980s. It is commonly known as one of the most accurate OCR engines available and was launched as an open source AI software with sponsorship from Google in 2006. Its primary implementation is meant for unstructured data processing and text from image extraction, executed entirely from a common line interface.
PaLM
PaLM, yet another language model developed by Google is trained on 540 billion parameters. This has evolved into a dense decoder-only transformer model trained with the Pathways system. It is the first one that used the Pathways system to train large-scale models with 6144 chips, along with being the largest TPU-based configuration. What makes PaLM stand apart from the rest is the fact that the model outperformed 28 out of 29 NLP tasks in English when compared to other models.
Rasa Open Source
Rasa is among the most popular open source AI software used to build conversational interfaces. While the company mainly drives monetization from its enterprise product, it also has a powerful open source edition and a separate toolset for enhancing AI assistance. You can use Rasa to build custom ML models or leverage its pre-built library of models written in TensorFlow. Rasa Enterprise bolts on to the open source platform, bringing SSO-based security, service level agreements, and dedicated support.
