# Algorithm references and notices

## Institutional marks

`src/polyclustx/display/assets/borelli.png` (Centre Borelli) and
`src/polyclustx/display/assets/paris_cite.png` (Université Paris Cité) were
supplied by the repository owner. They are reproduced unchanged to identify
research affiliations, not as a claim of institutional endorsement.
These marks are not licensed under the software's MIT license; rights remain
with their respective institutions. Reuse must follow institutional requirements:

- https://centreborelli.ens-paris-saclay.fr/fr
- https://u-paris.fr/charte-graphique-et-outils/

The separate PolyClustX project mark is an original AI-generated transparent
X-and-nodes design. It is not an institutional mark.

## Algorithm adaptations

CONAN, DGF and G-CoMVKM are framework-native adaptations informed by their
reference implementations. The copyright notices and MIT license below apply
to the respective derived portions:

- DGF: https://github.com/HaoranZ99/DGF — Copyright (c) 2026 Haoran Zheng
- G-CoMVKM: https://github.com/KristinaP09/G-CoMVKM — Copyright (c) 2025 Kristina P. Sinaga

SGLA and UMC are independent implementations of their published formulations;
their unlicensed standalone source files, pretrained networks and datasets
are not redistributed. UMC deliberately operates on user-supplied features.

The Co-EM and co-training spectral estimators are framework-native PyTorch
adaptations informed by mvlearn (https://github.com/mvlearn/mvlearn).
COMPLETER's architecture and objective are adapted from the XLearning reference
(https://github.com/XLearning-SCU/2021-CVPR-Completer). Their MIT notices follow.

IDEC, DCP and MFLVC are reimplementations of their published clustering
objectives using polyclustx's shared building blocks. Original standalone scripts,
datasets and pretrained weights are not redistributed. Paper and reference
implementation links, scope and deliberate differences are documented in
docs/background/algorithms.md and docs/user_guide/clustering_models.md.
