Data Science and the Knowledge Discovery AdventureThis talk will cover the important steps involved in the data science and knowledge discovery process:
• Initial fact gathering (interview domain experts, review reports, articles, state-of-the-art)
• Identify the problem (prediction, classification, statistical analysis, etc.)
• Survey supporting data sources
• Understand the data (numerical, categorical, text, sampling rate, data quality issues, etc.)
• Selecting relevant features and sources
• Acquire the data (set up agreements with the data stewards, APIs to download, etc.)
• Merge data sources (temporal, spatial, common key, other ontologies...)
• Feature Engineering (non linear domain knowledge or physics-based relationships)
• Build data processing pipeline (may need to tap into data stream, develop parallel processing algorithm, federated learning etc.)
• Build model and test (tune hyper-parameters, cross validation.)
• Analyze/Validate results (do the results make sense. Does it answer the original question).
• Deploy/Publish (Monitor and assess benefits)
