camelyon16-features

Pre-extracted Phikon features from CAMELYON16 whole slide images for benchmarking cancer classification methods.

What camelyon16-features is

camelyon16-features is a computational pathology dataset published by Owkin. It contains numerical representations derived from the CAMELYON16 challenge, a widely used benchmark for detecting breast cancer metastases in lymph node tissue.

The source whole slide images were originally gathered by Radboud University Medical Center in Nijmegen and University Medical Center Utrecht in the Netherlands. Owkin generated this dataset by extracting slide features using the Phikon model.

By providing pre-computed embeddings, the dataset facilitates efficient benchmarking of multiple instance learning (MIL) algorithms and cancer classification workflows without the need to process raw histopathology slides directly.

How it was made

The dataset consists of embeddings extracted from CAMELYON16 whole slide images using the Phikon feature extraction model.

The resulting feature data are packaged in Parquet format and can be accessed using data tools such as Polars, Dask, and the Hugging Face Datasets library.

Strengths and limits

Good at

  • Enables rapid testing of multiple instance learning methods without requiring extensive compute for whole slide feature extraction.
  • Embeddings are generated with the openly available Phikon pathology model.
  • Provided in Parquet format for compatibility with tools such as Polars, Dask, and Datasets.

Watch out for

  • Contains pre-extracted feature vectors rather than the original whole slide histopathology images.
  • Representations are constrained to the feature space produced by the Phikon encoder.

Questions
