Thanks. Here are the duties for Data Scientist. I also perform this. Can i also apply under that NOC? Teaching is just one part of the job of a prof. the other parts are research and service.
Data science combines statistics, artificial intelligence (AI), database research, and software development. Data scientists identify past actions that predict relevant future outcomes.
Data science includes at least 4 stages:
- Initial exploration (for example, analyze data to understand the quality and structures). Generate a summary and description of the key variables and values based on initial exploration
- Data model building or value-based pattern identification
- Model testing (for example, applying the model to new data to generate predictions)
- Model deployment (using the model to make predictions and/or decision in the real world)
In general, data scientists clean the data, which involves removing data that may have errors or contradict other data in the pattern. They also:
- Select relevant subsets of data records to reduce the amount of information to explore
- Identify the most relevant data variables
- Determine the complexity and nature of data, information or business models required
- Use techniques such as bagging (averaging), stacking, bootstrapping and meta-learning
- Apply different models (for example, association mining, classification mining, cluster mining, neural networks, Bayesian networks or support vector machines) to the same data
- Compare model results to select a preferred model
- Apply the selected model to new data to find patterns and clusters or test and generate predictions or estimates of expected outcomes
Some data scientists may use prescriptive analytics (building different prediction models based on various potential decision actions) to guide decision makers to a desired outcome.
