1. Data Mining: Data mining is the process of discovering patterns and insights from large datasets using algorithms and statistical techniques. It involves extracting useful information from raw data to help businesses make better decisions. 2. Machine Learning: Machine learning is a subset of artificial intelligence that focuses on developing algorithms and models that allow computers to learn from data and make predictions or decisions without being explicitly programmed. 3. Artificial Intelligence: Artificial intelligence (AI) is the simulation of human intelligence processes by machines, such as learning, reasoning, and self-correction. It involves creating intelligent systems that can perform tasks that normally require human intelligence. 4. Natural Language Processing: Natural language processing (NLP) is a field of artificial intelligence that focuses on enabling computers to understand, interpret, and generate human language. It involves tasks such as text analysis, sentiment analysis, and language translation. 5. Deep Learning: Deep learning is a subset of machine learning that uses neural networks with multiple layers to learn complex patterns in data. It is particularly effective for tasks such as image recognition, speech recognition, and natural language processing. 6. Predictive Analytics: Predictive analytics is the use of data, statistical algorithms, and machine learning techniques to identify trends and patterns in data and make predictions about future events or outcomes. It is often used in marketing, finance, and healthcare to forecast customer behavior or business performance.
