1. Core AI Concepts
- Artificial Intelligence (AI) – The simulation of human intelligence in machines, enabling them to perform tasks such as learning, problem-solving, and decision-making.
- Machine Learning (ML) – A subset of AI that enables systems to learn from data and improve performance without explicit programming.
- Deep Learning (DL) – A type of ML that uses multi-layered neural networks to process complex data and perform advanced tasks such as image and speech recognition.
- Neural Network – A computing system inspired by the human brain, consisting of layers of interconnected nodes (neurons) that process data.
- Algorithm – A set of rules or instructions used by AI systems to analyze data and make decisions.
- Dataset – A structured collection of data used to train, validate, and test AI models.
2. Machine Learning Methods
- Supervised Learning – A type of ML where the model is trained on labeled data, meaning the input-output pairs are provided.
- Unsupervised Learning – ML where the model learns patterns and structures from unlabeled data.
- Reinforcement Learning – A learning method where an agent interacts with an environment to maximize rewards through trial and error.
3. AI Specializations
- Natural Language Processing (NLP) – A branch of AI that enables machines to understand, interpret, and generate human language.
- Computer Vision – A field of AI focused on enabling machines to process and analyze visual data like images and videos.
- Generative AI – AI models that can create new content, such as text, images, or music, based on learned patterns.
- LLM (Large Language Model) – Advanced AI models trained on vast datasets to understand and generate human-like text.
- Prompt Engineering – The process of crafting effective inputs (prompts) to guide AI models like ChatGPT to produce better responses.
4. AI Development and Deployment
- Training Data – The dataset used to teach an AI model how to recognize patterns and make predictions.
- Inference – The process where a trained AI model makes predictions based on new input data.
- Bias (in AI) – Systematic errors in AI models that arise due to biased training data or flawed algorithms.
- Model – A mathematical representation of a learning process used to make predictions or decisions.
- API (Application Programming Interface) – A set of tools and protocols that allow developers to integrate AI functionalities into applications.
