Data science is a multidisciplinary field that covers a wide range of topics. To become proficient in data science, you should have a solid understanding of the following key areas:

1. Statistics:

   • Probability theory
   • Descriptive statistics
   • Inferential statistics
   • Hypothesis testing
   • Regression analysis
   • Bayesian statistics

2. Mathematics:

   • Linear algebra
   • Calculus
   • Multivariate calculus (for deep learning)
   • Differential equations (for time series analysis)

3. Programming and Data Manipulation:

   • Python or R programming languages
   • Data manipulation libraries like Pandas (Python) or dplyr (R)
   • Data visualization libraries like Matplotlib, Seaborn (Python), or ggplot2 (R)

4. Machine Learning:

   • Supervised learning (e.g., linear regression, decision trees, support vector machines)
   • Unsupervised learning (e.g., clustering, dimensionality reduction)
   • Deep learning (e.g., neural networks, convolutional neural networks, recurrent neural networks)
   • Model evaluation and selection techniques
   • Feature engineering

5. Data Preprocessing:

   • Data cleaning
   • Missing data imputation
   • Outlier detection and treatment
   • Data scaling and normalization DATA SCIENCE COURSE IN PUNE
