When people picture machine learning technology, many think of a process entirely devoid of human intervention. While this technology can make decisions without guidance, they still require ample training. Automation exists to improve training efficiency. However, humans can greatly influence a model's training and development.
What is HITL?
HITL stands for human-in-the-loop. It refers to an iterative feedback process involving annotators, data scientists, operation teams and more. With HITL machine learning, humans interact with systems to provide feedback. The goal is to improve accuracy and create a more efficient training process.
Every time a human offers feedback to the system, it updates and adjusts. With HITL, entire teams can collaborate to continually improve the system's precision and change how it views the data it sees. What is HITL? Visit this website to know more information.
Generally, HITL model development involves a team of annotators and scientists who will feed systems datasets that are already accurately annotated and labeled. The model will then map new classifications and fill in knowledge gaps. It does this much faster and at far greater volumes than a human team could do alone. Humans and algorithmically-generated systems work together to help a machine-learning model learn more quickly than ever.
What is HITL and its Role in Machine Learning Outcomes?
HITL aims to combine human intervention with a traditional automated process to make machine learning models smarter. Think of it as a teacher and student scenario. In this case, the machine learning model is the student attempting to absorb as much information as possible. While that student could get lost in textbooks, having guidance from a teacher makes it far easier. Teachers push students in the right direction, helping them grasp concepts faster to improve their knowledge.
That's what a HITL workflow does. It produces better results, allowing machine learning models to make more accurate predictions while decreasing the time to deployment.
There are some drawbacks. For example, many argue that HITL is more cumbersome and prone to human error than full AI-based alternatives. However, having more people involved in a HITL workflow can dramatically improve efficiency, cutting back training times far more than if no humans were involved.
