I like that they have over 10,000 public and private datasets available to try, and that they have over 20,000 pre-built models to try. They have a robust API, and the tools are intuitive to use. The dashboard could be more colorful and clear. Try it out, it's free for up to two users. You can use it with your own data, and it's free. I work for a large company that needed to build a machine learning model to predict an employee's performance against metrics. We started with a basic dataset and a few simple pre-built models, but it was clear that we needed more data and more models to train our model. After training with our own data, we realized that we needed to expand our data coverage and use more pre-built models. With TrainingData, we had access to a much more robust set of models for our use case. I like that my data is stored in one place with easy to access files. There's nothing i dislike about this software. If you are looking for high quality training sets or validation sets then get it because its definitely worth it! We use these services to train our models, but also validate them on new datasets so as not to waste time building something that will be of no value if validated on existing data.
