Key Components of Data Science
- Data Collection: The process begins with gathering data from various sources, which can include structured data (e.g., databases) and unstructured data (e.g., text and images).
- Data Cleaning: Raw data often contains errors or missing values. Data scientists meticulously clean and preprocess the data to ensure accuracy and completeness.
- Exploratory Data Analysis (EDA): EDA involves visualizing and analyzing data to identify patterns, trends, and outliers. It helps in framing hypotheses and understanding the data’s structure.
- Feature Engineering: Data scientists engineer new features or modify existing ones to enhance the predictive power of machine learning models.
- Machine Learning: Machine learning algorithms, such as regression, clustering, and deep learning, are applied to build predictive models and uncover hidden insights.
- Model Evaluation: Models are rigorously evaluated using metrics like accuracy, precision, and recall to assess their performance.
- Deployment: Successful models are deployed in real-world applications, where they generate predictions or recommendations.
