Artificial intelligence (AI) refers to computer software that exhibits intelligent behavior. AI systems can be divided into two broad categories: knowledge representation systems and machine learning systems. Knowledge representation systems are also referred to expert systems. These systems provide a structure for capturing and encoding the knowledge of a human expert in a particular domain. One of the most famous examples of an expert system used today is MYCIN, an experts system for diagnosing and recommending treatment of bacterial infections of the blood, developed by Shartliffe and associates at Stanford University. The second category of AI is machine learning system which creates new knowledge by finding previously unknown patterns in data. The main machine learning techniques of the system is neural networks and genetic algorithms. Neural networks simulate the human nervous system. These systems model the interaction between nerve cells. This system is composed of richly connected sets of neurons

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
