-    "description": "This evaluation tests the trained Autoencoder (Primitive Extractor + Temporary Decoder) on the entire Clotho development set (3,631 audio files). The goal is to measure how accurately the 512-dimensional bottleneck retains the acoustic information of the original 768-dimensional BEATs features.",
-    "metrics_explanation": "Because this is a continuous feature reconstruction task and not a discrete classification task, standard 'Classification Accuracy' cannot be used. Instead, we use two metrics: 1) Average L1 Error (measures the absolute numerical difference between original and reconstructed features, lower is better) and 2) Cosine Similarity % (measures the directional alignment between the original and reconstructed vectors, acting as our 'Reconstruction Accuracy', higher is better)."
+    "title": "Clotho Primitive Extractor - Full & Cross-Dataset Evaluation",
+    "description": "This evaluation tests the trained Primitive Extractor (fine-tuned on Clotho via Reconstruction Loss) on two fronts: 1) The full Clotho development set to verify baseline reconstruction, and 2) The entire ESC-50 dataset to test cross-dataset generalization.",
+    "metrics_explanation": "Because this is a continuous feature compression task, we use Cosine Similarity % as our 'Reconstruction Accuracy'. It measures how perfectly the 512-dim bottleneck retains the directional alignment and acoustic information of the original 768-dim BEATs features."
