Lightly

Lightly is a data-centric AI platform specifically designed to address the data bottleneck in computer vision. It empowers machine learning teams to manage, curate, and select the most impactful data from massive, often unlabeled, datasets. By adopting an active learning and self-supervised learning approach, Lightly helps organizations build high-performance vision models more efficiently and cost-effectively. The platform consists of a suite of powerful tools: LightlyOne for cloud-based data curation, LightlyTrain for label-free model pretraining, and LightlyEdge for intelligent data collection on-device.

How to use Lightly

The workflow with Lightly is designed to integrate seamlessly into existing MLOps pipelines:

1. Connect Your Data Source: Begin by connecting Lightly to your existing data storage, such as Amazon S3, Google Cloud Storage, or Azure Blob Storage. The platform can handle millions of images or video frames.
2. Curate Data with LightlyOne: Upload your raw, unlabeled visual data. LightlyOne's algorithms analyze the data to identify redundancies, outliers, and hard cases. You can then apply various selection strategies (e.g., coreset, diversity, uncertainty) to automatically curate a small, diverse, and highly informative subset of your data.
3. Pretrain Models with LightlyTrain: Use the curated data subset with LightlyTrain, an open-source framework, to pretrain your vision model (e.g., YOLO, RT-DETR, ViT). It leverages self-supervised learning methods like DINOv2, allowing the model to learn powerful representations from your specific data domain without requiring any manual labels.
4. Label and Fine-Tune: Since you've selected only the most valuable data, your labeling effort is drastically reduced. Label this small, curated dataset and use it to fine-tune your pretrained model. This process leads to faster convergence and superior model accuracy compared to training on randomly sampled data.
5. Optimize Data Collection with LightlyEdge: For continuous improvement, deploy the LightlyEdge SDK on edge devices (e.g., cameras, drones, autonomous vehicles). It pre-filters data in real-time, ensuring that only the most valuable or novel data is sent to the cloud for storage and retraining, saving significant bandwidth and costs.
