  • Python Built-in Functions (Text, numeric, date, utility functions)
  • Python User Defined Functions
  • Stripping out extraneous information
  • Normalizing data
  • Formatting data
  • Important Python modules for data manipulation (Pandas, Numpy, re, math, string, date time etc)

6: Data Analysis – Visualization using Python

  • Introduction exploratory data analysis
  • Descriptive statistics, Frequency Tables and summarization
  • Univariate Analysis (Distribution of data & Graphical Analysis)
  • Bivariate Analysis (Cross Tabs, Distributions & Relationships, Graphical Analysis)
  • Creating Graphs- Bar/pie/line chart/histogram/ box plot/ scatter/ density etc)
  • Important Packages for Exploratory Analysis -NumPy Arrays, Matplotlib, seaborn, Pandas and scipy stats etc

7: Basic Statistics & Implementation of Stats Methods in Python

  • Basic Statistics – Measures of Central Tendencies and Variance
  • Building blocks – Probability Distributions – Normal distribution – Central Limit Theorem
  • Inferential Statistics -Sampling – Concept of Hypothesis Testing
  • Statistical Methods – Z/t-tests (One sample, independent, paired), Anova, Correlation and Chi-square
  • Important modules for statistical methods: Numpy , Scipy , Pandas

8: Python: Machine Learning – Predictive Modeling – Basics

  • Introduction to Machine Learning & Predictive Modeling

  • Feature engineering & dimension reduction
  • Concept of optimization & cost function
  • Concept of gradient descent algorithm
  • Concept of Cross validation(Bootstrapping, K-Fold validation etc)
  • Model performance metrics (R-square, RMSE, MAPE, AUC, ROC curve, recall, precision, sensitivity, specificity, confusion metrics )

9: Machine Learning Algorithms & Applications – Implementation in Python

  • Linear & Logistic Regression
  • Segmentation – Cluster Analysis (K-Means)
