Introduction to Data Science

Introduction to Data Science – Introduction to Machine Learning – What is Python – Role ofPython in Machine Learning and Python –Installing Python – Python IDE’s – JupyterNotebook Installation and usage.

Python Packages

What is package – Advantage of usingpackages over core Python – Pandas – Numpy– Sci-kit Learn – Mat-plot library.

Manipulating data

Selecting rows / observations – RoundingNumbers – Selecting columns and fields –Merging data – Data aggregation – Datamunging techniques.

Statistics

Probability Basics – What is meant byprobability, Types, ODDS ratio – StandardDeviation – Data deviation andDistribution , Variance. Bias variantTradeoff – Underfitting, Overfitting.Distance metrics - Euclidean Distance,Manhattan Distance. Outlier analysis -What is an Outlier?, Inter Quartile Range,Box & whisker plot, Upper Whisker, LowerWhisker, Scatter plot, Cook’s Distance, -Missing Value treatment - What is NA?,Central Imputation, KNN imputation,Dummification. Correlation - Pearsoncorrelation, positive & Negativecorrelation.
