Human-in-the-loop (HITL)
What is human in the loop?
Human-in-the-loop (HITL) is a crucial process in data annotation that combines human expertise with machine automation. This hybrid approach is highly effective in ensuring high-quality labelled datasets, particularly for machine learning models that power AI (artificial intelligence) applications.
Benefits of human-in-the-loop
Improved accuracy
Combining human expertise with machine automation ensures the highest possible data quality
Efficient handling of edge cases
Machines may struggle with ambiguous or rare cases, but human annotators can provide the necessary context for accurate labelling
Cost-effectiveness
While human involvement is necessary, automating simple tasks reduces the overall cost, making the process efficient and scalable
The HITL process explained
Human-in-the-loop involves a cycle where machines first attempt to label the data using automated techniques. Human annotators then review and correct the results. Here’s a breakdown of the HITL process:
Automated labelling
Machines attempt to label a dataset using pre-trained models. This is particularly effective for large volumes of data that contain well-known patterns.
Human review
Human experts intervene to audit and correct any errors or inconsistencies. This is vital for edge cases where machine predictions might fail.
Feedback loop
Once human corrections have been made, their outcomes are fed back into the ML model to help it improve its future labelling accuracy. The system becomes more intelligent over time, gradually reducing the reliance on human intervention for repetitive tasks.
