Artificial Intelligence is a vast field and with the increase in the demand for AI engineers, more and more institutes have tried to provide courses that specialize in this field. The courses of each institute differ from one another but there is some core course that is same in almost all the institutes as they provide a base for future learning. Some of the core subjects in the AI domain are as follows:

Mathematics

• Calculus

• Linear algebra

• Probability

Statistics

- Correlations,
- Type I and Type II error
- Precisionand Recall

Computer Science

• Sorting algorithms (quicksort, merge sort, insertion sort, etc.)

• Shortest path algorithms (Dijkstra’s, A*)

• Tree algorithms (pre-, in-, post-order traversal)

• Memory requirement and computational cost

• Data structures – Trees: binary search tree, heap, Queues, stacks, priority queues, Linked lists, Hash map, and Hash table

• Various search algorithms – Breadth-first search, Depth-first search, etc. Uniform search, Iterative deepening search
