The best part about decision oven is that it's easy to use, you don't need any coding knowledge or previous experience with data science tools like R etc., It also helps in building predictive models using regression analysis techniques which are very useful while working at an enterprise level as well! I have used this tool extensively during my work life span so far but i haven’t came across anything negative yet from their side!! Nothing really.
If your looking into developing some predictions/models then definitely go ahead & try out D'Ovn!! You will surely find something of value here! We were solving problems related customer churn rate prediction by creating various machine learning algorithms such us k-Nearest Neighbours algorithm (KNN), Naive Bayes classifier among other things through d' OvN package available within r language environment. This helped me solve our problem easily without having much technical background required :) Highly.
