Advanced Analytics

Value of AA

• Evolution: Excel > Storage > Tableu > Alerts > predicting the future > ML >
• Applications:
  • Descriptive (historical. advanced statistics) >
  • Predictive (Future. Uses ML. detection of fraud) >
  • Prescriptive (influence the future. Data driven decision making); Optimization;

Five concepts

Statistical Learning

• Frame of understanding the data based on statistics
• Eg: L.Regression: Used in predictive analytics
• Linear model: regression or classification

Inference vs prediction

• Inference : process of evaluating the relationship of predictor and the response
• Prediction: process of using a model that is yet to happen

Flexibility vs Interpretability of models

• Flexibility: capture a wide range of phenomena (Data fit)
• Interpretability : Design a Pattern to facilitate the decision

Regression vs classification

• Regression : Continuous variable.
• classification: discrete variable

Supervised vs unsupervised learning

• Supervised " Labelled data sets, Training , CNN , Decision tree
• unsupervised : Classification
  • Anomaly detection
  • Find hidden structure
  • Eg: Customer segmentation; Purchase patterns, simplify data, monitoring
