-
-
-## Model Details
-- **Model Name:** `Scentience OVLE Small v1`
-- **Developed by:** Kordel K. France
-- **Date:** September 2025
-- **Architecture:**
-  - **Olfaction encoder:** 138-sensor embedding
-  - **Vision encoder:** CLIP-based
-  - **Language encoder:** CLIP-based
-  - **Fusion strategy:** Joint embedding space via multimodal contrastive training
-  - **Parameter Count (Base):** 2.2M (without CLIP), 153.4M (with CLIP)
-  - **Parameter Count (GAT):** 9.3M (without CLIP), 160.5M (with CLIP)
-  - **Embedding Dimension:** 512
-- **License:** MIT

-## Intended Use
-- **Primary purpose:** Research in multimodal machine learning involving olfaction, vision, and language.  
-- **Example applications:**
-  - Cross-modal retrieval (odor → image, odor → text, etc.)
-  - Robotics and UAV navigation guided by chemical cues
-  - Chemical dataset exploration and visualization
-- **Intended users:** Researchers, developers, and educators working in ML, robotics, chemistry, and HCI.
-- **Out of scope:** Not intended for safety-critical tasks (e.g., gas leak detection, medical diagnosis, or regulatory use).
-

-
-## Training Data
-- **Olfaction data:** Language-aligned olfactory data curated from GoodScents and LeffingWell datasets.
-- **Vision data:** COCO dataset.
-- **Language data:** Smell descriptors and text annotations curated from literature.

-## Evaluation
-- Retrieval tasks: odor→image (Top-5 recall = 62%)
-- Odor descriptor classification accuracy = 71%
-- Cross-modal embedding alignment qualitatively verified on 200 sample triplets.

-## Limitations of Evaluation
-To the best of our knowledge, there are currently no open-source datasets that provide aligned olfactory, visual, and linguistic annotations. A “true” multimodal evaluation would require measuring the chemical composition of scenes (e.g., using gas chromatography mass spectrometry) while simultaneously capturing images and collecting perceptual descriptors from human olfactory judges. Such a benchmark would demand substantial new data collection efforts and instrumentation.
-Consequently, we evaluate our models indirectly, using surrogate metrics (e.g., cross-modal retrieval performance, odor descriptor classification accuracy, clustering quality). While these evaluations do not provide ground-truth verification of odor presence in images, they offer a first step toward demonstrating alignment between modalities.
-We draw analogy from past successes in ML datasets such as precursors to CLIP and SigLIP that lacked large paired datasets and were evaluated on retrieval-like tasks.
-As a result, we release this model to catalyze further research and encourage the community to contribute to building standardized datasets and evaluation protocols for olfaction-vision-language learning.

-
-## Limitations
-- Limited odor diversity (approx. 5000 unique compounds).
-- Embeddings depend on sensor calibration; not guaranteed across devices.
-- Cultural subjectivity in smell annotations may bias embeddings.
-
----
-
-## Ethical Considerations
-- Not to be used for covert detection of substances or surveillance.
-- Unreliable in safety-critical contexts (e.g., gas leak detection).
-- Recognizes cultural sensitivity in smell perception.
-
----
-
-## Environmental Impact
-- Trained on 4×A100 GPUs for 48 hours (~200 kg CO2eq).
-- Sensor dataset collection required ~500 lab hours.
