3.4 How does Ada's reasoning engine work?

Each of the 10,000+ symptoms and attributes, and 120+ risk factors in Ada's knowledge base has a probability attached to it for how strongly associated it is with a variety of over 3,600 conditions. Ada’s reasoning engine, developed by our team and customized to our specific settings, builds on this data and on the answers that the user provides to each question. This produces the probabilistic list of most likely causes with a level of accuracy and safety that sets Ada apart from others.
