What is Data Science?
Data science is an interdisciplinary field that focuses on collecting, analyzing, and deriving insights from data to support decision-making. It combines statistics, machine learning, programming, and domain expertise to extract meaningful patterns and predictions from structured and unstructured data.
Data science plays a crucial role in industries such as healthcare, finance, e-commerce, and marketing by enabling organizations to make data-driven decisions. Businesses use data science to:
- Improve customer segmentation and personalization.
- Detect fraud and anomalies in financial transactions.
- Optimize supply chain management and logistics.
- Enhance medical diagnosis and patient care through predictive analytics.
Key Techniques in Data Science
- Data Preprocessing – Cleaning and transforming raw data to ensure accuracy and consistency.
- Statistical Analysis – Using probability, distributions, and hypothesis testing to identify trends and relationships.
- Machine Learning – Applying algorithms to automate predictions and decision-making based on data patterns.
What is AI?
Artificial intelligence (AI) is a branch of computer science that enables machines to simulate human intelligence by performing tasks such as reasoning, problem-solving, learning, and decision-making. Unlike traditional programming, where explicit rules dictate behavior, AI systems learn from data and improve over time through adaptive algorithms.
How AI Differs from Traditional Programming
- Traditional programming follows predefined rules and logic explicitly coded by developers.
- AI models learn from patterns in data, adapting and improving without human intervention.
- Instead of rule-based decision-making, AI systems leverage statistical models and neural networks to handle complex tasks.
Key Subsets of AI
- Machine Learning (ML) – A subset of AI that enables systems to learn patterns from data and make predictions without explicit programming.
- Deep Learning (DL) – A specialized form of machine learning using neural networks to process complex data such as images, speech, and large datasets.
- Natural Language Processing (NLP) – AI techniques that enable computers to understand, interpret, and generate human language, used in chatbots, translation, and voice assistants.
