How quickly does Watson learn?
Watson is continuously learning with each user interaction. The information captured by Watson throughout each interaction is analyzed and turned into knowledge on a monthly basis for top answers. It's important for Watson to gain a significant sample size of data, to validate trends in similar user questions. For questions that do not generate a top answer, considered to be part of the knowledge base searching, these are re-ranked using machine learning algorithms in real time. This technique will allow the 'best' answer to be selected from multiple options and usage to determine the best one.
