Review Udacity Artificial Intelligence Nanodegree

I cannot recommend this nanodegree despite that the video lecture quality improved tremendously. The price tag of this series of nanodegrees is very pricey and will definitely not help you get jobs unless you are quite familiar with AI already. Most of the concepts covered in lecture, can be found on the internet in much cheaper and digestable forms. I wish I can get a refund in this course.

This is the first nanodegree I regret purchasing. I had positive experience with machine learning engineer nanodegree and digital marketing nanodegree. The first iteration of ML Nanodegree was not very cohesive but it was a really good overview as well as hands on experience for ML. I am surprised that the artificial intelligence one seems to have much higher quality course content but terrible result.

I thought I'd be getting started with AI playing with basic, fun, but informative projects. Nope just puzzles just printing out lines and lines of game board. While an important foundation of AI, there's no need to pay Udacity price tag. Udacity projects are supposed to be fun, real world, practical, and a new style of education. For puzzles, printing out game boards using dashes and dots, I can go to Coursera and many college courses to find that, better explained

Video quality has improved across the board

Professors and assistants from Georgia Tech is spearheading the teaching with a little bit of Luis Serrano here and there. Overall the lecture videos and animations are professional. They are updated, and professional, becoming more suitable for the price tag. The lectures by  the professor at Georgia is quite pleasant and well designed. They are great at explaining high level intuitions and concepts of AI. One minus is that the lectures don't translate to problem solving. They will not successfully prepare students for the problem sets and projects.

Projects are very dry and hard to get through

As explained below, the first installment is quite dry. Projects are difficult to go through. Without building a solid foundation, you are hit with a Sudoku puzzle right away. Sample codes are filled with cryptic python list comprehensions with poorly chosen variable names. Painful, purely painful. 

This nanodegree is an expensive rip-off

This nanodegree, like the SmartCar series are chopped into several semesters. Due to the difficulty level of the material, it is hard to obtain the full-set of skills in a single semester. It also means that you have to invest north of $1800 to complete the actual nanodegree. It's a deal breaker for me. Udacity is turning greedy for sure. It basically thinks it can charge you anything below a college degree or a graduate degree. It's important to realize that traditional academic expenses cover many resources, activities and experiences in addition to lectures.

The first installment of the nanodegree only scratches the surface of artificial intelligence

The first installment touches a little more than solving puzzles like Sudoku and basic games, while learning constraints problems, building a basic agent. While an important foundation, it is quite dry. I think it is quite tough for independent learners to go through this dry material. 

Again materials are stitched together

Udacity likes to patch materials together. While there's nothing wrong with recycling, the lectures are not always cohesive, and can be quite frustrating for students.

Career prospect is dismal

Career prospect of this nanodegree will be dismal unless you finish the entire series, which is quite expensive. The first installment just touches constraint resolution, backtracking, and advanced technical interviews, but does not give you enough toolset to solve it. I recommend getting tutorials online and studying technical interview problems related to puzzle, solving instead. The sample code in this nanodegree will not be appropriate for interview use. 

Overall, I do not recommend this course. Google for better education in natural language processing, artificial intelligence and more.
