Overview

Commerce and research are being transformed by data-driven discovery and prediction. Skills required for data analytics at massive levels – scalable data management on and off the cloud, parallel algorithms, statistical modeling, and proficiency with a complex ecosystem of tools and platforms – span a variety of disciplines and are not easy to obtain through conventional curricula. Tour the basic techniques of data science, including both SQL and NoSQL solutions for massive data management (e.g., MapReduce and contemporaries), algorithms for data mining (e.g., clustering and association rule mining), and basic statistical modeling (e.g., linear and non-linear regression).

Syllabus

  • Key-value stores and NoSQL; tradeoffs of SQL and NoSQL
Part 2: Analytics
  • Topics in statistical modeling: basic concepts, experiment design, pitfalls
  • Topics in machine learning: supervised learning (rules, trees, forests, nearest neighbor, regression), optimization (gradient descent and variants), unsupervised learning
Part 3: Communicating Results
  • Visualization, data products, visual data analytics 
  • Provenance, privacy, ethics, governance

Introduction to Data Science is a MOOC offered by the University of Washington on the Coursera platform. Introduction to data science is a misleading title for this course because it is not introductory level and it does not have a sensible flow that builds from one week to the next as you would expect...

The lectures by Prof. Howe were fun and of good length to watch on a busy schedule. They supported the projects quite well and I think that the professor did an excellent job with this course. Unfortunately, some topics like Machine Learning lacked a programming assignment to support and apply the theory,...

This course gave an excellent platform to channelize my preparations for the industry. The very first week we had to do a project in Python, where we accessed Twitter API and did sentiment analysis on a sample of live tweets. Now people working in this area know that sentiment is an extremely important...

Professor Howe's lecture style is not always engaging, and a lot of material is covered. There were often over 3 hours worth of lecture material to review during the week. Along with following links and reading supporting papers, this left very little time for the assignments themselves. Prof. Howe did...

While course assignments are invaluable and aimed to build programming/analytical skills critical for understanding big data processing, machine learning, and data analysis, the video lectures are sketchy, boring, and not sufficient for assignments. Staff wasn't engaged or present on forums and there...

It was a mammouth ambition to cover the basics of data science in fewer days than Phileas Fogg took to travel around the world. The lectures, at time, felt disjointed, since there was so much material to cover. The breadth of coverage was phenomenal, though, and I am now at least comfortable with the cohort of big data jargons like Hadoop, HBase, CouchDB, Pregle, and MapReduce.

The first few weeks were focused on programming assignments using Python and SQL, both of which I had some familiarity with. The exercises were challenging enough for me to learn new tricks of the trade but didn’t feel like I was drowning. As the course moved on to MapReduce concepts, I started to struggle. But again, it was just the right level of challenge for a newbie that I felt compelled to motor through the quizzes.

DO NOT TAKE THIS COURSE.

IT'S A COMPLETE MESS!!! SO MANY TYPOS EVERYWHERE!!! THE TEACHER JUST THREW A BUNCH OF IDEAS TOGETHER AND CREATED PRESENTATIONS A FOUR YEAR OLD COULD MAKE.

BILL HOWE DOES NOT KNOW HOW TO COMMUNICATE IN GENERAL AND DID NOT PUT ANY EFFORT INTO MAKING THIS COURSE. DO NOT TAKE THIS COURSE IT'S A TOTAL SCAM! I JUST LOST $15 ON AWS TRYING TO DO HIS POORLY LAID OUT HOMEWORK ASSIGNMENTS (THAT'S WHY THIS REVIEW IS ALL IN CAPS!!!). I WAS 90% COMPLETE WITH THE ENTIRE COURSE SERIES (I WAS BEING STUBBORN) UNTIL I FINALLY HAD ENOUGH OF THIS MEDIOCRITY.

A MOOC SHOULD NOT BE THIS UNENJOYABLE!!!

CARLOS GUESTRIN AND EMILY FOX'S MACHINE LEARNING COURSE IS A MILLION TIMES BETTER AND THEY COME FROM THE SAME UNIVERSITY???

P.S. IF BILL HOWE EVER READS THIS REVIEW I HAVE A MESSAGE FOR HIM.

THINK YOUR LIFE OVER...TEACHING ISN'T FOR EVERYONE!!!

by Berk is taking this course right now.


He just doesn't have the ability to explain stuff. The examples he give are confusing, slides are boring and most importantly he is not prepared as you can see from his unorganised thoughts. I almost always found myself searching for the subject in google after he mentioned about them because it was impossible to understand the concepts/algorithms/methods from him. The course is definitely not introduction level either. May be I did wrong by following Andrew Ng's course in very beginning since my expectation got very high and I easily get disappointed when I can't find the same quality in other courses. As a result, you will see/hear many things in this course but you will not learn them from this instructor.

Having completed the Coursera JHU Data Science specialization that was focused on the R language, I wanted to dig deeper into the IT side of data science with this course. And as the course description listed acquaintance with Python, SQL or R as a prerequisite, I decided to go for it.

I guess I wasn't prepared enough, as the first week's assignment of a sentiment analysis in Python left me completely baffled.

Even though I found the introduction to the course very inspiring, as the lecturer obviously understands the challenges of defining Data Science very well, I had to drop this course because you cannot fulfill assignments within reasonable time without having prior knowledge of Python.

The lectures cover a lot of topics which I like. The assignments are extremely difficult for people without strong background in Python.

Taken the course. Total farce. Instructor never replies to discussion forums.

The asisgnments have wrong information. And videos have typos. Total mess. Stay away.

Is hard to provide a good feeback to the "communicating data science result" course.

The first week went down quiet well, the teacher was good, but in order to complete the assignment you need to already know Tableau or similar.

Howevere the peer review of the assignment look like not working well as there is not enough people taking this course to be score and score (so you can not pass it)

Last week assignment ... i am speachless. Can not complete, instruction look like not working and you need to already know the system.

a complete waste of money, at least for me.

DO NOT TAKE THIS COURSE

although the lectures were quite interesting and I learned a lot the HW are badly written and extremely frustrating (not because they are hard, but because they are very old and confusing)

Excellent overview of several topics in Data Science. Instructor was engaging and presented the material well. I have used many of the techniques taught in this course in subsequent work.
