Encord Active

Test, validate, and evaluate your models and surface, curate, and prioritize the most valuable data

Encord is an advanced platform designed to significantly enhance the accuracy and efficiency of machine learning (ML) models, particularly in computer vision.

It provides a comprehensive suite of data curation, labeling, and model evaluation tools — helping ML practitioners confidently deploy production-ready AI applications.

By leveraging Encord, users can enjoy many benefits, including dramatically increased edge-case class performance, faster labeling speeds that streamline data pipelines, and improvements in model average precision (mAP) through effective data curation.

The platform enables robust model evaluation, allowing for the quick identification and correction of blind spots or data drift, ensuring models remain accurate amid evolving data landscapes. Furthermore, it facilitates the comparison of model performance and integrates human oversight in active learning workflows, accelerating the AI development lifecycle from initial data curation to final deployment.

Encord’s advanced label validation features and tools are meant to create balanced datasets, automatically surfacing label errors and validating labels to enhance ML model performance. Also, there is support for vector embeddings and AI-assisted quality metrics to help users easily identify and correct problematic data samples.

This focus on ensuring high-quality training data, combined with the ability to inspect model predictions compared to ground truth, allows teams to communicate errors effectively back to the labeling team. And as a result, we all get to benefit from better AI apps and services. Neat.

What are the key features? ✨

Advanced Model Evaluation: runs quality metrics and error analysis to uncover class-specific weaknesses, data drift, and failure modes across multimodal datasets.
Automatic Label Error Detection: uses vector embeddings, AI-assisted metrics, and model confidence to automatically surface and flag potential mislabels for correction.
Active Learning Workflows: prioritizes high-impact uncertain samples for labeling to optimize training efficiency and accelerate performance gains.
Embedding Visualizations: clusters data and failures visually so teams can explore patterns, outliers, and similar issues intuitively.
Explainability Reports: generates clear reports on model performance and issues to share insights with technical and non-technical stakeholders.

Who is it for? 🤔

Encord Active helps ML engineers, data scientists, and AI teams building production computer vision or multimodal models who struggle with opaque failures, noisy labels, or inefficient labeling. Its especially useful for those iterating toward deployment in regulated fields like healthcare or autonomous systems, where rigorous validation, drift detection, and targeted curation matter most.

Examples of what you can use it for 💡

ML engineer on production detection models: imports predictions, surfaces failure modes and label errors, then prioritizes uncertain samples for relabeling to lift mAP without labeling everything.
Computer vision researcher fine-tuning foundation models: uses embedding clusters and metrics to diagnose class imbalances, detect drift, and curate balanced subsets for better evaluation.
Data annotation lead managing large-scale projects: runs active learning to send only high-value samples to labelers, cutting costs and speeding iteration cycles significantly.
AI team in medical imaging: validates models on DICOM data, flags errors automatically, and generates reports to ensure reliability before clinical use.
Startup developing physical AI or robotics: curates multimodal datasets from raw captures, identifies weak spots early, and applies targeted fixes for robust real-world performance.
