+# NMF Model - samples mode - 4D
+
+Pre-trained nmf model for transcriptomic data compression.
+
+## Details
+- **Mode**: samples-centric compression
+- **Dimensions**: 4
+- **Training data**: TRACERx lung cancer transcriptomics
+- **Created**: 2026-01-10T13:15:48.266414
+
+## Usage
+
+```python
+import joblib
+from huggingface_hub import snapshot_download
+
+# Download model
+local_dir = snapshot_download("jruffle/nmf_samples_4d")
+model = joblib.load(f"{local_dir}/model.joblib")
+
+# For classical models (PCA/UMAP):
+# model contains: 'pca', 'umap', 'robust_scaler', 'gene_order'
+
+# For TabPFN models (with UMAP reduction):
+# model contains: 'tabpfn_embedding', 'umap_final', 'raw_embeddings', 'input_scaler', etc.
+# Uses UMAP instead of PCA for non-linear dimension reduction of TabPFN embeddings
+```
