Workshop
- Forecast vs Prediction
Code
- import pandas as pd
- cars_df = pd.read_csv('used_cars_maruti.csv')
- variable.describe()
- variable.info()
- variable.shape
- variable[0:5] | range of rows to be shown. Minus 5 is also possible
- variable['Column Title'][0:5]

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
