學生對 华盛顿大学 提供的 Machine Learning: Classification 的評價和反饋

worthless

I enrolled in this specialization to learn machine learning using GraphLab Create. Half way into the specialization the creators sold Turi, GrapLab's parent company, making it non available to the general public (not even by paying) and then all the knowledge devalued. I wish I had known this and I would have enrolled on a different specialization. The creators still give you the possibility of using numpy, scikit learn and pandas but I had already done a lot with GraphLab create. The time I invested on my nights after work became a waste. I was trying to convince the company I worked for to buy licenses for GraphLab create.

Coursera should not allow folks to create courses that promote a private license course because it would make people waste their time and money if they decide to privatize the software.

Don't take this course, and if you take it then only use GraphLab create when the authors give you no other option.

Teaching style: Carlos was good, Emily is not very clear and loses focus of the topics and often rambles. She seems very knowledgeable but she lacks clarity of exposition when compared to Carlos or Andrew Ng.

I was pretty disappointed with this course. Firstly, the course did not seem well balanced meaning that some weeks--particularly week 2--had A LOT of materials to watch and really felt like it was two weeks crammed into one, and then other weeks barely had anything.

Secondly, the exercises seemed unclear, poorly thought out and not really helpful. There were many errata that really should have been fixed in the beta iterations of this course.

Thirdly, I really would like to see more application and less discussion of implementing algorithms.

Fourthly, the "scaling" section was also a major disappointment. While it is mildly interesting to learn about stochastic gradient descent, I think it would have been more interesting to have a discussion about how classifiers work in a parallelized computing environment or actually to try one out using Spark.

Finally, given that GraphLab/Dato/Turi was just acquired by Apple, I question whether it is worthwhile to take this course as ALL the materials are taught using a library that in all likelihood will cease to exist.

The videos are fine. But, It's SIMPLY TERRIBLE to force people to pay to be able to do the quizzes. There was no such a thing in the first two courses (by the way, I gave high rates for both). It is OK to pay for the verified certificate, however, disabling the functions in the course is a wrong way to earn money, because people who want to learn the course might not necessarily want the certificate, and this is unfair to them because it limits the resources available. This whole Specialization thing starts to make me feel like you guys are in urgent need of money, rather benefiting the community. Remember there are tons of free resources on the internet, and this only undermines your strengths. You will lose tons of potential fans. Stop being seemingly arrogant.

If you are considering this specialization I would recommend the Andrew Ng course instead and the main reason is that it isn't depend on proprietary ML framework. Despite the good lectures, the assignments don't help you develop the knowledge required for ML developer role.

Taking in consideration the permanent postponing the courses delivery, from summer 2016 to summer 2017, finally the most interesting part of the specialization was cancelled. I'm completely disappointed with the specialization learning expirience.

very Vague and in efficient in transferring the knowledge. Teachers have tendency to overcomplicate very simple ideas to look more mathematically in-depth. It is not true and just causes confusion. I ended up to look only on slide and do the exercises rather than watching their videos

The Course is not of the said level and is a very convenient way of promoting their software, the faulties are non responsive n the forums

Could not install required software (turicreate library for python) in a Windows Environment. The course should be explicit about that.

This specialization is delayed for months now - very annoying! Don't give them money!

No good without the missing course and capstone projects

After 2 great courses this one is really disappointing!

Not happy about course 5 & 6 got cancelled.

Poor quality.
