In contrast to the intelligence exhibited by humans or other animals, artificial intelligence (AI) refers to the perception, synthesis, and inference of information made by computers. Speech recognition, computer vision, interlanguage translation, and various mappings of inp uts are some examples of tasks where this is done. Advanced web search engines like Google Search, recommendation systems used by YouTube, Amazon, and Netflix, speech recognition software like Siri and Alexa, self driving cars like Waymo, generative or crea tive tools like Chat GPT and AI art, automated decision making, and winning at the highest levels of strategic game systems like chess and go are just a few examples of applications for AI. In the present review, I have discussed uses of AI in different fie lds like medicine, transportation, agriculture etc.
