Domain Knowledge For Data Science
The most ancient archetype of a data scientist is from drew conway where he paints a data scientist as someone who is well versed in mathematics statistics programming hacking skills and domain knowledge substantive expertise.
Domain knowledge for data science. Reading literature and attending presentations can boost one s domain knowledge. In some cases data scientists might need to also have strong subject matter expertise additional to the technical skills but in other cases depending also on the industry or on the way in which the organization for which he she works is structured that might not be the same. Data practitioners that have industry knowledge can ask better questions and more pointed questions.
One of the most impactful places for domain knowledge is the question development stage. The importance of domain knowledge in data science also becomes clear when you think about the four factors you need to consider at the beginning of any data science project. Precision accuracy representativeness and significance.
This means there is no easy single answer to where to gain domain knowledge. The technical aspects of the roles of data scientists are extremely transferable and so adaptation of domain knowledge takes place. Domain knowledge definitely helps in better making sense of the data and of the problem s context.
It thus becomes obvious that domain knowledge is important both in the framework as well as the body of a data science project. We c an use the same definition in data science to say domain knowledge is the knowledge about the environment in which the data is processed to reveal secrets of the data. Having knowledge in the domain in which data science is being done can help data scientists at various points in the scientific process.
A data scientist can t easily choose to go through med school or the experience of being treated for a chronic illness. Check it to learn more. However while there are numerous books articles courses and self help guides dedicated to the mathematical statistical and programming.
It will make the project faster cheaper and more likely to yield a. With more companies entering the world of data iot and the cloud it is easier to see the benefits of hiring specialists to help them with their data science needs. This episode talks about the importance of domain knowledge in data science.
