What is Pathways Language Model (PaLM)?

Google PaLM (Pathways Language Model) is a machine learning model used for natural language processing tasks. It is designed to handle large-scale language understanding problems that require significant computational resources. Some examples of these tasks include question answering, text classification, and machine translation.

PaLM uses Pathways to scale its training process to 6144 TPU chips, which is a significant increase compared to other language models. This scaling is achieved using data parallelism, where the data is divided and processed across multiple TPU chips, and model parallelism, where the model is split and processed on a single TPU chip.

The training process of PaLM is efficient and uses a combination of English and multiple languages to create a comprehensive model. The training data includes a variety of sources, such as web pages, books, Wikipedia, conversations, and GitHub code.

A special vocabulary is used in the training process, which preserves important information like whitespaces and individual digits. This “lossless” vocabulary ensures that the model can accurately understand and process the data, especially for code and numbers.

Overall, the design of Google PaLM and the use of the Pathways system to scale its training make it an effective tool for handling large-scale language understanding tasks and achieving high-accuracy results.

Comparing the Capabilities of OpenAI GPT-3 vs PaLM
