Where the name comes from
Our first job was rock recognition, so we're named after ore: cevher. Demir-1 takes its name from here. Later models will follow the metal sequence: copper, silver, gold.
About
We build models in Türkiye. Our first product Demir-1 recognizes 63 rocks and minerals from a single photo. 125 MB, 288×288 input, EfficientNet-B3.
What's next
- Pushing past 63 classes
- Adding English to outputs
- Adding field notes, location and hardness fields
- Models beyond rocks
How the test set was built
Training and test never mixed; we split images by MD5. The test set holds hand-held stones shot at different angles and light. That's why 81.15% reads close to the field. Validation is 83.12%.
