PeytonT/cross-modal-retrieval

Cross Modal Retrieval

Retrieves semantically related items across paper and repository modalities.

Model Details

• Artifact type: full fine-tuned model
• Base model: sentence-transformers/all-MiniLM-L6-v2
• Backbone type: encoder
• Model ID: C6
• Tier: T5_cross
• Role in stack: specialized Repository Library component

This model is part of the Repository Library stack, a research system for indexing, retrieving, aligning, and reasoning over scientific papers, structured paper content, repositories, and cross-domain links between them.

Model Sources

• Hugging Face repo: https://huggingface.co/PeytonT/cross-modal-retrieval
• Hugging Face collection: https://huggingface.co/collections/PeytonT/research-library-6a49c589ef4d763f7539b50d
• GitHub repository: https://github.com/peytontolbert/research_library
• Experiment config: https://github.com/peytontolbert/research_library/blob/main/models/experiments/c6_cross_modal_retrieval.json
• Models directory: https://github.com/peytontolbert/research_library/tree/main/models

Intended Use

• Primary use: Retrieves semantically related items across paper and repository modalities.
• Downstream use: retrieval, ranking, planning, paper understanding, or cross-domain reasoning inside the broader Repository Library system, depending on the model family.
• Out of scope: production safety claims, benchmark claims beyond the tracked experiment config, or deployment without task-specific validation.

Training Data

The training inputs for this package were assembled from the following Repository Library data sources:

• Source arxiv_pdfs_structured: structured PDF shards containing text, equations, figures, and tables.
• Source github_repos: repository graph and code chunk data exported from the Repository Library repo pipeline.

Training Procedure

• Sources: arxiv_pdfs_structured, github_repos
• Input fields: paper_chunk, code_chunk
• Target fields: shared_embedding
• Train/val/test split: [0.9, 0.1, 0.0]
• Max samples: 4000
• Batch size: 8
• Precision: bf16
• Objective: contrastive
• Learning rate: 5e-05
• Max source tokens: 256
• Max target tokens: 128
• Fine-tune strategy: full_finetune
• Max steps: 1000

Compute

• Hardware: 4x RTX_3090 (24 GB)
• Distributed strategy: ddp
• Estimated GPU hours in config: 0

Evaluation

• Declared metrics: recall_at_10, ndcg_at_10
• Status: this card reflects the current tracked experiment configuration and packaged weights in the Repository Library model stack.

Usage

from transformers import AutoModel, AutoTokenizer

repo_id = "PeytonT/cross-modal-retrieval"

tokenizer = AutoTokenizer.from_pretrained(repo_id)
model = AutoModel.from_pretrained(repo_id)

Limitations

• These cards are generated from tracked experiment metadata and packaged artifacts, not from a separate benchmark report or external audit.
• Several training sources are pipeline outputs from the Repository Library codebase rather than standalone public datasets.
• These models are components of a larger research system and should be validated in their target workflow before deployment.
