### AI Fundamentals #### Definition - **Artificial Intelligence (AI):** A machine's ability to think, learn, and act like humans. - AI enables computers to study data, analyze patterns, make decisions, and solve problems without human intervention. #### History of AI - **Early Ideas (Before 1950s):** Concepts of smart machines in science fiction. - **1950s - The Beginning of AI:** - 1950: Alan Turing introduces the Turing Test. - 1956: John McCarthy coins the term "Artificial Intelligence." - **1960s-1970s – Early Computer Programs:** AI solves small problems and plays simple games based on rules. - **1980s - Start of Machine Learning:** - Computers begin to learn from data. - Expert systems developed for medicine and banking. - **2000s - Internet and Big Data:** AI applications in mobiles, websites, search engines, speech tools, and chatbots emerge. - **2010s-Present – Modern AI:** AI becomes integrated into everyday life and various industries. #### AI Subfields - Knowledge Engineering - Machine Learning - Computer Vision - Natural Language Processing (NLP) - Robotics #### Industry Applications of AI - **Healthcare:** Disease diagnosis, treatment planning, drug discovery, surgery support, virtual health assistants, hospital management. - **Finance:** Fraud detection, customer support, loan/credit decisions, insurance policy work, personalized services, quick claim processing. - **Retail:** (Not detailed in provided text, but generally includes personalized shopping, inventory management). - **Agriculture:** Crop monitoring, soil/weather analysis, smart irrigation, pest/disease control, harvesting/sorting, market price prediction. - **Education:** Personalized learning, smart tutoring systems, automatic grading, virtual classrooms, language translation/support, career guidance. - **Transportation:** (Not detailed in provided text, but generally includes self-driving cars, traffic management). ### Challenges in AI AI helps in doing things faster and easier but also brings new challenges, primarily related to how AI behaves, makes decisions, and ensures fairness and safety. #### Ethics in AI - AI systems should adhere to moral values and human principles to ensure technology benefits society without causing harm. - **Example:** AI in hospitals should assist doctors, not replace medical decisions. #### Bias and Fairness in AI Systems - **Bias:** Showing preference or discrimination. If AI is trained on biased data, its output will be biased. - **Fairness:** Providing equal treatment and avoiding discrimination. - **Example:** An AI trained on male-dominated job application data might unfairly reject female candidates. #### Transparency in AI Systems - **Transparency:** Being open and clear about how AI systems work and make decisions. - Users should understand the reasoning behind AI's results and suggestions. - **Example:** A bank's AI rejecting a loan application must clearly state the reasons (e.g., low credit score). ### AI in Research #### AI in Experimentation - AI plays a crucial role in scientific experiments, making them more efficient. - **Data Collection & Analysis:** Collects and studies large datasets, identifies patterns and trends. - **Simulation:** Conducts experiments on computers before real-life trials. - **Method Suggestion:** Proposes better experimental methods or settings. - **Accuracy Improvement:** Reduces human errors, provides precise readings. - **Benefits:** Faster, cheaper, more reliable experiments. - **Examples:** - **Chemistry & Physics:** Predicts material reactions. - **Medicine:** Tests new drugs safely using computer models. - **Space Research:** Analyzes satellite data, predicts weather/planet conditions. #### AI in Multi-disciplinary Research - AI facilitates collaboration among different subjects to solve complex problems. - **Integration:** Brings together experts from various fields (science, technology, medicine, social sciences). - **Problem Solving:** Helps address complex issues requiring diverse perspectives. - **Teamwork:** Supports collaboration by analyzing data from all fields. - **Examples:** - **Medical Research:** Develops better tools for robotic surgeries. - **Agricultural Research:** Improves crop growth and irrigation systems. - **Educational Research:** Studies student learning and skill improvement. - **Environmental Research:** Predicts floods, droughts, and pollution. - AI acts as a bridge, enabling data sharing and new knowledge discovery across disciplines. ### Generative AI #### Meaning of Generative AI -
