Andrew Ng, former Baidu chief scientist and an artificial intelligence expert, will reportedly join Woebot, a chatbot developer, as chairman.

The chatbot developed by Woebot can reportedly help people handle their mental health problems. The company's technology is based on cognitive behavioral therapy, which focuses on emotional management and customized handling solutions for mental problems like depression and anxiety.

A research conducted by Stanford University shows that after using Woebot for two weeks, people's anxiety and depression can be reduced.

Ng believes that machine learning can make great contributions in the medical field and this is the reason for his joining the company.

Ng revealed during a media interview that he will still participate in other projects. He said his position in Woebot is to serve the board of directors of the company and to provide support to their work. However, this will not be a full-time job.
