- 5. The Turing Test was designed back in 1950 by mathematician and computing engineer Alan Turing to determine whether a machine can show human intelligence. In simple terms; can a computer talk like a human? At the time Turing called it the Imitation Game. As part of the test, a human judge has a text conversation with unseen players and evaluates their responses. If the evaluator could not differentiate the machine from the human, the machine would be said be deemed artificially intelligent
- 6. How does Machine Learning Relate to AI? Machine learning implies to the technologies and algorithms that allow systems to recognize patterns, make decisions, and improve themselves through experience and data. Although the terms artificial intelligence (AI) and machine learning are frequently used interchangeably, (machine learning is a subset of the larger category of AI. ) Artificial intelligence signifies computers' general ability to mimic human thought while carrying out tasks in real-world environments Nora

- 10. AI Technologies AI encompasses a wide range of technologies, including: Expert Systems: programs that use specialized knowledge to make decisions in narrowly defined areas. Natural Language Processing (NLP): technologies that enable computers to understand and generate natural language. Computer Vision: systems capable of recognizing and interpreting images.
- 11. What does AI need to LEARN? ! One of the capabilities of both Artificial and Human intelligence is learning. Learning in the context of AI refers to a systems ability to improve its skills and performance based on experience and analysis of dependencies in large datasets. This process is fundamental to creating AI systems capable of adapting to new tasks and situations. ! All AI models do this if it cant adapt based on data, then it simply isnt artificial intelligence. While there are different types, ranging from simple AI models to fully fledged deep neural networks, they all have to meet this initial criteria.
- 12. Types of Machine Learning Algorithms (ML) AI uses various types of ML algorithms to create advanced, intelligent systems: 1.Machine Learning (ML): this technique allows computer systems to learn from data without being explicitly programmed. ML algorithms analyze input data, identify patterns, and use this information to make predictions or decisions. Examples include image classification, sentiment analysis in texts, and demand forecasting. 2.Neural Networks: these are mathematical models inspired by the biological structures of the brain, used for pattern recognition and information processing. Deep neural networks consist of layers of neurons interconnected and processing input data through different levels of abstraction. They are used in image and sound processing.
- 13. Types of Machine Learning Algorithms (ML) 1.Deep Learning (DL): a subfield of machine learning that uses multi-layered neural networks to analyze data. DL is particularly effective in processing large amounts of unstructured data, such as images, sounds, and texts. Applications include speech recognition, language translation, image generation, and medical diagnostics. 2.Robotics: this field involves designing, constructing, and operating robots. In the context of AI, robotics often uses ML algorithms for navigation, object manipulation, and interaction with the environment. Intelligent robots can operate in dynamic and unpredictable environments, making autonomous decisions. Q: How Does Machine Learning Work? Machine learning involves developing algorithms that enable computers to learn from data and make decisions autonomously, similar to human learning through experience. Instead of being explicitly programmed, these algorithms identify patterns in data to predict outcomes and make informed decisions.

- 15. uses of AI Customer service Customer service teams can get feedback from customers by using AI. For example, AI- powered information can provide agents with information on client intent, language, and sentiment so they are aware of how to approach an encounter. Medical diagnosis Provides more exact diagnoses, detects hidden patterns in imaging investigations, and predicts how patients will respond to specific medications. This leads to better treatment strategies, fewer clinical errors, and more accurate diagnosis. (ADVANTAGES OF AI) Image and facial recognition It can help make data safer and more secure. For example, face authentication can ensure that only the appropriate person has access to sensitive information that is intended specifically for them. Recommendation systems AI content recommendations help people stay engaged and informed. For example, Virtual(Siri and Alexa.), Personalized content on streaming platforms, Apps that suggest best routes based on traffic.
