Welcome to an exploration of the nasa-smd-ibm-v0.1 model, also known as Indus. This state-of-the-art RoBERTa-based transformer model is designed to enhance natural language processing capabilities specifically tailored for NASA’s Science Mission Directorate (SMD). In this article, you will learn how to use this remarkable model effectively for your scientific projects.
Model Overview
The Indus model was fine-tuned on a selection of scientific journals and articles related to NASA SMD applications. Let’s break down its components:
- Base Model: RoBERTa
- Tokenizer: Custom
- Parameters: 125 Million
- Pretraining Strategy: Masked Language Modeling (MLM)
You can access a distilled version of the model with 30 million parameters here.
Training Data
The model was trained on a diverse set of materials, including:
- Wikipedia English (Feb 1, 2020)
- American Geophysical Union (AGU) Publications
