Final Assignment Part One

1. How would YOU define AI?

Your definition of AI can be similar or different from the ones given in the course.

Artificial intelligence (AI) refers to the simulation of human intelligence in machines that are programmed to think like humans and mimic their actions. The term may also be applied to any machine that exhibits traits associated with a human mind such as learning and problem-solving.

2. Explain an application or use-case of AI that fascinates YOU.

It may or may not be something that is mentioned in the course.

Artificial Intelligence in Healthcare :
Artificial Intelligence in Business
Artificial Intelligence in Education
Artificial Intelligence in Autonomous Vehicles
Artificial Intelligence in Social Media
Artificial Intelligence for a Better World
Artificial Intelligence in Tourism

3. Pick a specific industry or an aspect of our lives or society and describe how YOU think it will be impacted by Artificial Intelligence in future.

What you discuss may or may not be something that is mentioned in the course.

Artificial Intelligence in Education:

It must be very tedious for a teacher to grade homework and tests for large lecture courses. A significant amount of time is consumed to interact with students, to prepare for class, or work on professional development. But, this will not be the case anymore.

Though it can never replace human work, it is pretty close to it. So, with the automated grading system checking multiple-choice questions, fill-in-the-blank testing and automated grading of students can be done in a jiffy.

It can tell the areas, where there is a need for improvement –

A lot of times, it happens that the teachers may not be aware of the gaps that a student might face in the lectures and educational materials. This can leave students confused about certain concepts. With AI, the system alerts the teacher and tell what is wrong. It gives students a customized message which offers hints to the correct answer.
