Human in the loop (HITL) Annotation

Human in the loop annotation is a process of annotating a particular data, especially images with the help of humans and machines in a way which is faster, more accurate and scalable than the conventional ways. In image processing, this concept is of great value for such operations as object detection, segmentation, and classification, where the potential for judgement by an employee is provided in order to guarantee the adequacy and accuracy of the annotations made.

How AI Human In The Loop Annotation Works?

Initial Machine Annotation: There are other proposals where a machine learning model or an automated system is used to create first annotations on the image (for bounding boxes around objects or segmentation of regions).
Human Review and Correction: It is then manually curated by the humans where the correction of any wrong or missed annotations by the model happens, alteration of labels or modification of regions of interest happens.
Active Learning: Another feature of the system is that it can learn from correction made by human beings. There is always the possibility of periodically retraining the machine when enough labeled data in terms of human input has been used and collected.
Feedback Loop: The more the specific machine learn from the annotated images which are corrected by human beings, the more it is relied on for annotation, but in cases of complication, the machines are supervised by human beings to make the process flexible.

Benefits of Human in the loop annotation:

Increased Efficiency: Taking into account that the process is fully automated, the speed is higher than in case of manual annotations only.
Improved Accuracy: People’s supervision decreases the number of mistakes a machine learning model might have.
Cost-Effective: Saves time in marking large datasets while at the same time having quality assurance.
Training Better Models: Active learning means the model can be improved over time solely because of inputs from a human.

Infosearch’s human-in-the-loop approach brings it a little step from complete automation while at the same time optimizing the strengths of both human and computers. Enhanced system accuracy is the first validity benefit gained from this approach, eliminating bias, making ethical decisions are possible while improving the flexibility and scalability of a system. Our humans in the loop are ready to assist you in sourcing and labeling the best quality training data and to further check and improve your predicted results from your model.
