Course Description

This course will teach you how to start from scratch in answering questions about the real world using data. Machine learning happens to be a small part of this process. The model building process involves setting up ways of collecting data, understanding and paying attention to what is important in the data to answer the questions you are asking, finding a statistical, mathematical or a simulation model to gain understanding and make predictions. All of these things are equally important and model building is a crucial skill to acquire in every field of science. The process stays true to the scientific method, making what you learn through your models useful for gaining an understanding of whatever you are investigating as well as make predictions that hold true to test. We will take you on a journey through building various models. This process involves asking questions, gathering and manipulating data, building models, and ult...

Model Building and Validation is an advanced data science course provided by AT&T through Udacity. The course is listed as "advanced" because it assumes prior knowledge of machine learning, statistics, linear algebra and calculus. Despite the stated prerequisites, math doesn't play a large role, so you will still be able to understand most of the content even if your only preparation is Udacity's intro to machine learning. The course spans 4 lessons that detail the process of extracting value from data through questioning, modeling and validation. Lesson 1 is a general introduction to the QMV process with each of the following lessons digging into each component of QMV in more detail. The course somewhat oversells its length as none of the lessons take more than a few hours despite the course being listed at an estimated 8 weeks with 6 hours of study per week. Model Building and Validation follows the same formula as other Udacity c... Model Building and Validation is an advanced data science course provided by AT&T through Udacity.

The course somewhat oversells its length as none of the lessons take more than a few hours despite the course being listed at an estimated 8 weeks with 6 hours of study per week. Model Building and Validation follows the same formula as other Udacity courses, with each lesson taking the form of a series of short lecture videos interspersed with quizzes. The lecturers are easy to understand and the video quality is generally good, although the videos and course materials have some glitches that need to be ironed out. I won't grade the course too harshly on bugs, since all courses are buggy at the very beginning, and they will likely be fixed in the near future. As for the content itself, the simple idea of framing a data analysis as a tree to track and organize the decisions you make along the way is probably the most useful thing you'll take away from this course. The course also does a good job getting students to think about some of the high-level decisions that must be made when conducting a data analysis. The content gets rockier when it delves into specifics after lesson 1, particularly in the models lesson. The lectures occasionally dive too quickly into the low level details of machine learning techniques that students may not have seen before. Additionally the validation section focuses much more on model evaluation metrics like ROC curves, the confusion matrix and derived metrics that fall out of it, than validation itself. Model Building and Validation is a good course that provides a nice framework for approaching data analysis, but it gets bogged down in some machine learning specifics that don't add much to the overarching theme.
