I believe if there are more practices and much challenging ones it would be more beneficial.

Este fue más práctico pero igual, mucha teoría, poca práctica

Excellent content except for decision trees

good

BON

its a great course that I have done in my life .I am really excited that I should able to learn some thing new from Andrew ng which is best professor of all time. I am really thankful to the all the team members and the staff who contribute in creating the specialization machine learning course . I am the luckiest student that I should participate and join the coursera platform for my personal growth . I really re commend this course and specially the course platform for the machine learner who want to be a part of this platform . This platform provide a great opportunity to learn new thing and deep dive into the new trending technology .

Lab

Why Course Two Was Operationally Hollow This course promised depth in decision trees, random forests, and XGBoost—but delivered mimicry, not architecture. Key concepts like entropy, information gain, and ensemble logic were introduced without derivation, context, or programming scaffolding. Students were expected to implement complex algorithms from scratch despite never being shown how recursion, data partitioning, or impurity metrics actually work in code. Autograders enforced formatting rituals rather than validating understanding, punishing deviation while never explaining edge cases like pure nodes or split logic. The labs relied on sedative walkthroughs and vague diagrams, leaving learners to reverse-engineer functionality from silence. Every skill gained came not from instruction, but from reverse-engineering its collapse.

La verdad no me gustó porque finalmente uno lo intenta y sin aprobar los laboratorios que no entiendo por que dan error si apruebo los test, segun el sistema igualmente indican que no estás aprobado y no hay forma de obtener los certificados aunque hayas cursado todo y aprobado los examenes remanentes, asi que mal, realmente me ha pasado ya varias veces con coursera asi que me rindo siento que así no vale la pena tanto esfuerzo porque al final vale es el certificado

If I could give it negative stars I would. You have completely wasted my time and money. I got to the next-to-last question on the last graded lab, and although my results appeared to match what was required -- according to the lab feedbac - an odd Python error was triggered that caused my submission to be ungrade-able. ZERO useful feedback provided. This ended up being a rip-off.

No means to get help for final assignment. Received correct expected answers for all four questions but was given a 0% on the grade with no access to course help.

Personally, I did not like the coding aspect of this course. Theoretically, this course is sound

Got a 0/100 for going by directions for a coding assignment. No discussion tab.

I am not able to get access to the lab and quizzes for course 2 and course 3

Very brief overview, use out-dated Tensorflow, not practical at all.

Unable to un-enroll whatsoever.

problem submitting the lab

I dont get a certificated

sucks, highly overated.
