Artificial intelligence (AI) is the broad branch of computer science. The goal of AI is to create systems that can function intelligently and independently. AI is the simulation of human intelligence processes by machines, especially computer systems. In computer science, artificial intelligence (AI), sometimes called machine intelligence, is intelligence demonstrated by machines, in contrast to the natural intelligence displayed by humans. It is a fact that chatbots perform tasks on the concept of Artificial Intelligence (AI) and machine learning. The traditional goals of AI research include reasoning, knowledge representation, planning, learning, natural language processing, perception and the ability to move and manipulate objects. There are two ways AI works i.e. symbolic based and data based in which we need to feed a lot of information before it can learn. Particular applications of AI include expert systems, speech recognition and machine vision. Much of speech recognition is statistically based hence it is known as statistical learning. Humans can see with their eyes and process what they see, whereas this is a field of computer vision. Computer vision falls under the symbolic way for computers to process information. It does image processing which is even though not related to AI but is required for computer vision. It does pattern recognition as well. Machines are better at pattern recognition because they can use more data and dimensions of data. We can replicate the structure and function of human brain we might be able to get cognitive capabilities in machines. It is also a field of neural networks and deep learning and we use those to learn complex things. If we get a network to scan images from left to right and top to bottom the convolution neural network work. The CNN is used to recognize objects in a scene. This is how computer recognition fits in and object recognition is accomplished through AI. AI can be categorized as either weak or strong. Weak AI, also known as narrow AI, is an AI system that is designed and trained for a particular task. Virtual personal assistants, such as Apple’s Siri, are a form of weak AI. Strong AI, also known as artificial general intelligence, is an AI system with generalized human cognitive abilities. In AI, we can get the neural network to remember the limited past.
