Human-in-the-loop AI training
Power your artificial intelligence (AI) and machine learning (ML) projects with high-quality, compliant and scalable AI and ML model training data.
Human-in-the-loop AI training
NashTech human-in-the-loop (HITL) AI training services combine expert human validation with advanced automation to provide multilingual data preparation, annotation, labelling and rigorous output validation. This ensures your AI models are trained with accurate, bias-free datasets across more than 28 languages, meeting the highest industry standards.
AI models are only as good as the data they are trained on. HITL ensures accuracy, mitigates compliance risk and accelerates time-to-value by addressing the “garbage in, garbage out” problem that causes 78% of AI projects to fail.
We help our clients achieve more than 98.5% accuracy, up to 50% cost savings and scalable support from Centres of Excellence in Vietnam and India. Our blend of skilled professionals and generative AI (GenAI) powered tools ensure quality, compliance and rapid scalability for global enterprises.
Eliminate unreliable AI outputs with expert human review
Many organisations struggle with inconsistent, incomplete or biased training data leading to unreliable AI outputs. Without expert human review, automated systems can perpetuate errors and bias.
Increasing scrutiny from regulations like GDPR and the EU AI Act means AI training data must be ethically sourced, validated and auditable. Manual compliance is costly and error prone.
Manual data labelling and annotation cannot keep up with the scale required for modern AI/ML projects, delaying time-to-market by 6-9 months.
AI models often require training data in multiple languages or specialised domains, which is difficult to source and validate without a global, skilled workforce.
Building and maintaining in-house annotation teams is expensive and diverts resources from core innovation.
Assure accuracy, compliance and continuous improvement
Support global AI initiatives with high quality data. Our services ensure you achieve more than 98.5% accuracy across more than 28 languages.
Our highly skilled professionals and workflow management tools ensure bias detection, accurate outputs and ethical compliance so that your projects meet GDPR/EU AI Act standards.
Our Centres of Excellence in Vietnam and India provide your organisation with rapid scalability. We have the capacity to handle millions of data points, reduce time-to-market and operational costs by up to 50%.
Automate up to 70% of routine tasks such as data cleansing, pre-labelling and anomaly detection and enable human experts to focus on complex or ambiguous cases.
We use KPI dashboards and continuous feedback loops to maintain higher than 99% accuracy, provide audit trails and drive continuous improvement.
