UNI2-h-features

Precomputed UNI2-h patch features for TCGA, CPTAC, and PANDA slides to support downstream pathology models.

What UNI2-h-features is

UNI2-h-features is a collection of precomputed histological feature representations published by MahmoodLab. It contains patch-level embeddings extracted from whole-slide images across the TCGA, CPTAC, and PANDA datasets.

The dataset addresses the computational burden of processing whole-slide pathology images. By providing pre-extracted visual embeddings generated by the UNI2-h model, it serves as a drop-in resource that eliminates the requirement to execute repetitive forward passes over raw histology slides.

How it was made

Histological slides from TCGA, CPTAC, and PANDA are sampled into image patches of 256×256 pixels at 20× magnification. These image patches are then processed through the UNI2-h self-supervised vision transformer model using PyTorch to output numerical patch embeddings.

Cross-cohort histology evaluation
Conducting comparative studies or validating computational pathology methods across TCGA, CPTAC, and PANDA.
Algorithmic benchmarking
Benchmarking novel slide aggregation and analysis architectures using standardised 20× UNI2-h features.

Its authors require their terms to be accepted before the data can be read. Accept them on the original dataset page. The platform does not accept terms on your behalf, so the rows are not shown here.

Strengths and limits

Good at

  • Removes the substantial computational overhead of running UNI2-h forward passes over large slide collections.
  • Provides standardized representations extracted at 256×256 resolution and 20× magnification across three distinct pathology cohorts.

Watch out for

  • Embeddings are limited to the specific patch size of 256×256 pixels and 20× magnification.
  • Coverage is restricted to the TCGA, CPTAC, and PANDA cohorts.

Questions

Can I look inside UNI2-h-features without downloading it?

Not here: its authors gate it behind terms each user must accept on the original page. Its description and statistics are still shown.

What licence is UNI2-h-features under?

Its authors declare cc-by-nc-nd-4.0. Read the terms on the original page before reusing the data.

Which image cohorts are represented in the dataset?

The features are extracted from the TCGA, CPTAC, and PANDA histopathology cohorts.

What patch size and magnification are used?

Features are derived from patches extracted at 256×256 pixels and 20× magnification.

Which model generated these embeddings?

The embeddings were precomputed using the UNI2-h self-supervised vision transformer model.
