Introduction to Artificial Intelligence Definition of Artificial Intelligence (AI)? Artificial Intelligence (AI) refers to the creation of intelligent machines that can work and think like humans. History The historical backdrop of man-made consciousness (computer-based intelligence) traces all the way back to the 1950s when scientists initially started investigating the idea of making machines that could perform undertakings that commonly require human knowledge, like grasping the normal language, perceiving pictures, and simply deciding. Early AI research focused on developing algorithms and programs that could mimic the problem-solving abilities of human brains. This led to the creation of early AI applications such as expert systems and decision-making systems. During the 1980s and 1990s, artificial intelligence research moved towards the advancement of "AI" calculations, which permitted PCs to gain from information without being expressly customized. This led to the cre...
