Task-oriented finetuning for better embeddings on neural search

PyPI Codecov branch PyPI - Downloads from official pypistats

Fine-tuning is an effective way to improve performance on neural search tasks. However, setting up and performing fine-tuning can be very time-consuming and resource-intensive.

Jina AI's Finetuner makes fine-tuning easier and faster by streamlining the workflow and handling all the complexity and infrastructure in the cloud. With Finetuner, you can easily enhance the performance of pre-trained models, making them production-ready without extensive labeling or expensive hardware.

🎏 Better embeddings: Create high-quality embeddings for semantic search, visual similarity search, cross-modal text<->image search, recommendation systems, clustering, duplication detection, anomaly detection, or other uses.

Low budget, high expectations: Bring considerable improvements to model performance, making the most out of as little as a few hundred training samples, and finish fine-tuning in as little as an hour.

📈 Performance promise: Enhance the performance of pre-trained models so that they deliver state-of-the-art performance on domain-specific applications.

🔱 Simple yet powerful: Easy access to 40+ mainstream loss functions, 10+ optimizers, layer pruning, weight freezing, dimensionality reduction, hard-negative mining, cross-modal models, and distributed training.

All-in-cloud: Train using our GPU infrastructure, manage runs, experiments, and artifacts on Jina AI Cloud without worrying about resource availability, complex integration, or infrastructure costs.

Install

Make sure you have Python 3.8+ installed. Finetuner can be installed via pip by executing:

pip install -U finetuner

If you want to encode docarray.DocumentArray objects with the finetuner.encode function, you need to install "finetuner[full]". This includes a number of additional dependencies, which are necessary for encoding: Torch, Torchvision and OpenCLIP:

pip install "finetuner[full]"

⚠️ Starting with version 0.5.0, Finetuner computing is performed on Jina AI Cloud. The last local version is 0.4.1. This version is still available for installation via pip. See Finetuner git tags and releases.
