Workflows

End-to-end computational workflows implemented as fully-documented Jupyter notebooks — covering real satellite and scientific text datasets from raw acquisition through validated final outputs.


Satellite Remote Sensing

  • NASA PACE Ocean Color Analysis

    Atmospheric correction and spectral analysis of PACE OCI hyperspectral data targeting phytoplankton community classification and ocean colour retrieval from continuous-band sensor measurements.

  • Sentinel-2 Change Detection

    Preprocessing, spectral index computation, and classification applied to Sentinel-2 time-series imagery for land cover change detection mapping.

Applied NLP for Scientific Text

  • Named Entity Recognition

    Transformer pipelines for extracting domain entities, geographic markers, and scientific terminology from unstructured research text.

  • Topic Modeling & Semantic Structuring

    Organising unstructured scientific abstracts into latent thematic clusters using LDA and neural topic models.

  • Zero-Shot Document Classification

    Pre-trained language models for zero-shot tagging and classification of research documents on arbitrary criteria without task-specific fine-tuning.


Running These Notebooks

The raw .ipynb source for every workflow lives in the site repository, under docs/tutorials/. Download a single notebook from there, or clone the lot:

git clone https://github.com/bidhya/bidhya.github.io.git
cd bidhya.github.io/docs/tutorials

The pixi environment in this repository builds the site; it does not install Jupyter or the scientific stack each notebook needs. Run them under your own environment, installing the imports each notebook declares in its first cell.
