“If you want to be a good data scientist, you should spend ~49% of your time developing your statistical intuition (i.e. how to ask good questions of the data), and ~49% of your time on domain knowledge (improving overall understanding of your field). Only ~2% on methods per se.” Nate Silver, a statistician and writer who analyzes sports, elections and more. 

In this week’s podcast Jon Prial is joined by Tara Khazaei, Chief Data Scientist, National AI Team, Customer Success Unit at Microsoft. Jon and Tara talk about how domain knowledge, as well as statistical intuition, make for more successful outcomes in machine learning projects. They discuss performance through the lens of projects Tara and her team have led at Microsoft. 

In this episode you’ll hear: 

• Why you need enough, high-quality data 
• The importance of iterating and validating your approach to achieve the best performance
• The challenges bias and explainability pose to ML projects
• Why domain knowledge is crucial for successful outcomes
  
• How to decide when your model is ready to go into  production and why you need to go beyond accuracy
