The training data license propagates to the trained weights. - Personal, educational, and research use: **allowed** - Apps (including commercial): **allowed** — the NC clause applies to the weights, not to software that loads them. Users download the weights separately and accept the NC terms. - Redistributing or selling the weights themselves: **not allowed** The C++ inference engine ([CrispEmbed](https://github.com/CrispStrobe/CrispEmbed), MIT license) and GGUF converter are original clean-room implementations. ## Model details | Property | Value | |----------|-------| | Architecture | DenseNet-121 encoder + GRU attention decoder (with coverage) | | Parameters | ~6.8M | | Training data | CROHME 2016 (CC BY-NC-SA 3.0) | | Vocabulary | 112 LaTeX tokens | | CROHME 2014 eval | 36.1% raw / 36.3% parsed (greedy, 986 images) | ## Files | File | Quant | Size | |------|-------|------| | `hmer-hw-f32.gguf` | F32 | ~14 MB | | `hmer-hw-f16.gguf` | F16 | ~7 MB | | `hmer-hw-q8_0.gguf` | Q8_0 | 7 MB | | `hmer-hw-q4_k.gguf` | Q4_K | 4 MB | ## References - [Pytorch-HMER code (MIT)](https://github.com/whywhs/Pytorch-HMER) - [CrispEmbed inference engine (MIT)](https://github.com/CrispStrobe/CrispEmbed) - [CROHME competition](https://www.isical.ac.in/~crohme/)
