# Encoding Mismatch Analysis Data
This repository publishes the prepared numerical analysis artifacts associated
with **From Per-Image Low-Rank to Encoding Mismatch: Rethinking Feature
Distillation in Vision Transformers**. It is analysis data, not an image or
model-training dataset, and it does not redistribute ImageNet.
## Links
- Paper: https://arxiv.org/abs/2511.15572
- Hugging Face paper page: https://huggingface.co/papers/2511.15572
- Code and analysis scripts: https://github.com/thy960112/From-Per-Image-Low-Rank-to-Encoding-Mismatch
- Lift and WideLast checkpoints: https://huggingface.co/Huiyuancs/Encoding_Mismatch
## Load the default configuration
The default `npz_array_catalog` configuration has one row per safely inspected
array inside the original NPZ files. It records the source file, array key,
dtype, JSON-encoded shape, dimensionality, element count, finite numeric
summary statistics where applicable, a small JSON preview, and any safe
inspection error.
```python
from datasets import load_dataset
catalog = load_dataset(
"Huiyuancs/Encoding_Mismatch_Analysis_Data",
split="train",
)
```
## Load the manifest
The manifest records the repository-relative path, file type, byte size,
SHA-256 digest, and recommended loader for every artifact copied from the
GitHub repository's `Raw data/` directory.
```python
from datasets import load_dataset
manifest = load_dataset(
"Huiyuancs/Encoding_Mismatch_Analysis_Data",
"manifest",
split="train",
)
```
## Load an original CSV table
Each original CSV has a separate configuration. For example:
```python
from datasets import load_dataset
table = load_dataset(
"Huiyuancs/Encoding_Mismatch_Analysis_Data",
"cait_sep_sep_thresholds",
split="train",
)
```
## Download and read an original NPZ file
Use `hf_hub_download` for the original binary artifacts and keep NumPy's
pickle loading disabled:
```python
from huggingface_hub import hf_hub_download
import numpy as np
path = hf_hub_download(
repo_id="Huiyuancs/Encoding_Mismatch_Analysis_Data",
repo_type="dataset",
filename="raw/cait/dataset_pca/dataset_pca_results.npz",
)
with np.load(path, allow_pickle=False) as archive:
print(archive.files)
```
The same download method can be used with any `relative_path` from the
`manifest` configuration.
## Repository structure
```text
README.md
data/
├── manifest.csv
├── npz_array_catalog.csv
└── viewer_csv/ # only created when a source CSV needs it
raw/ # byte-identical copy of Raw data/
```
`data/npz_array_catalog.csv` is a compact inspection index, not a replacement
for the original arrays. `data/manifest.csv` supplies checksums for verifying
the originals. All released CSV files load directly with Hugging Face Datasets, so their configurations point to the byte-identical files under `raw/`; no viewer-normalized copies were needed.

## Source and intended use
The files are derived from the paper's representation-analysis workflow,
including per-image SVD, dataset-level PCA, and Spectral Energy Pattern
summaries. They are provided for inspecting the reported analyses and for
regenerating tables or figures with the corresponding GitHub scripts. The
artifacts are not a substitute for ImageNet-1K or for rerunning feature
extraction.
## License and third-party data
The repository content is released under `apache-2.0`. ImageNet images are not included; users remain responsible for the terms of ImageNet and all upstream software or model assets.
