General Tips before starting Programming in AI
Master Fundamentals First: Before starting programming in AI, choose a language of your choice (preferably Python) and master the basics of it. After mastering the basics, master programming fundamentals, algorithms, and data structures.
Start with High-Level Libraries: After mastering the language and data structure, go for a practical approach. Start learning High-Level Libraries and Frameworks like TensorFlow or PyTorch.
Hands-On Projects: Always work on a project. While learning any programming language, the best thing is to practice. The more you practice, more you remember the fundamentals. Apply your knowledge on projects.
