Datasets for Machine Learning & Artificial Intelligence (AI) training

Bringing the human touch to machine learning and AI training

Your algorithms need human interaction if you want them to provide human-like results. Our artificial intelligence training data service focuses on machine vision and conversational AI.

With over 1.8 million Clickworkers, we are ready to help you get more out of your algorithms through dedicated training datasets, system testing, and validation.

Managed Service Training Data for Machine Learning & Artificial Intelligence (AI)

As a full-service provider, we handle the entire process from start to finish.

After our initial project discussion, we evaluate your needs and develop an actionable plan. Your traproject is then divided up into smaller microtasks, placed online, and tested.

The initial project is released to a smaller selection of qualified Clickworkers that we feel are best suited for your task. As they complete individual microtasks, thousands of tasks are completed in record time.

All submitted tasks are checked for quality based on our internal guidelines. Finalized results can be sent to you on a continual or cumulative basis, via email, uploaded to your server, or through an API.

Contact a member of the clickworker service team today if you want to learn more about how our artificial intelligence training data services can help you train your algorithms with valuable human intelligence.

The Importance of Training Data for Machine Learning & Artificial Intelligence (AI)

Data scientists continue to work tirelessly to try and replicate human intelligence through the algorithms they create. And while they continue to make progress, the complex AI systems they are creating need more than just the code that defines them.

AI systems heavily rely on human intelligence in order to learn, develop, and act. As these systems learn from this data, they are better able to handle increasingly complex tasks.

clickworker offers training data for artificial intelligence systems that provide algorithms with the different variations of human intelligence that they need to be trained properly.

Processing of training data for your artificial intelligence systems

We simplify how you handle processing training data by doing all the work for you.

Through microtasks, we break up your project and hand it off to our large and qualified workforce. Not only do you receive valuable human intelligence, but we are able to sort through large amounts of data in no time.

Clickworkers can tag, edit images, plot points, and correct individual elements in order to provide you with high-quality data sets. bounding boxes

Training and testing of your artificial intelligence / AI systems

Our artificial intelligence training data services offer support from top to bottom. Our Clickworkers perform tests on your AI systems, filter through pre-programmed processes, and evaluate the results using human logic.

Comprehensive quality control of training data for your artificial intelligence systems

We put a lot of effort into providing you with a high-quality experience. All of our Clickworkers are thoroughly vetted, and any training data created is tested for quality.

Depending on the project, data sets are proofread or validated using the two-man rule, which requires peer review or majority decision before project completion.
