Case Study - Predicting Housing Prices
In our first case study, predicting house prices, you will create models that predict a continuous value (price) from input features (square footage, number of bedrooms and bathrooms,...). This is just one of the many places where regression can be applied. Other applications range from predicting health outcomes in medicine, stock prices in finance, and power usage in high-performance computing, to analyzing which regulators are important for gene expression.
In this course, you will explore regularized linear regression models for the task of prediction and feature selection. You will be able to handle very large sets of features and select between models of various complexity. You will also analyze the impact of aspects of your data -- such as outliers -- on your selected models and predictions. To fit these models, you will implement optimization algorithms that scale to large datasets.
Learning Outcomes: By the end of this course, you will be able to:
-Describe the input and output of a regression model.
-Compare and contrast bias and variance when modeling data.
-Estimate model parameters using optimization algorithms.
-Tune parameters with cross validation.
-Analyze the performance of the model.
-Describe the notion of sparsity and how LASSO leads to sparse solutions.
-Deploy methods to select between models.
-Exploit the model to form predictions.
-Build a regression model to predict prices using a housing dataset.
-Implement these techniques in Python....

I really enjoyed all the concepts and implementations I did along this course....except during the Lasso module. I found this module harder than the others but very interesting as well. Great course!

I really like the top-down approach of this specialization. The iPython code assignments are very well structured. They are presented in a step-by-step manner while still being challenging and fun!

Goes well beyond the statistics that I learned in engineering! Key concepts in regression such Ridge, Lasso and KNN. Use Python to build all your algorithms from the ground up.

This module is very rich in pratical assignments, as well as quizzes to force you to understand what you are doing. Everything is really well balanced, and all the materials are very complete. Is clear the passion from the tutors and teachers in this course. This really gives you the necessary will to proceed, and don't give up, even when things get pretty hard.

I love everything about this course. the course material is easy to follow. I also like the coding exercises. I highly recommend the specialisation so far (this is my second course)

Absolutely loved the way Emily tackled the course content - the knowledge I gained regarding LASSO & RIdge was something even I wasn't expecting. Also the optional video helped a lot to understand the mathematics better as compared to a mechanical write-down of the steps

This is probably the best course on Regression for ML out there

And this specialisation is probably the best! for Basic Machine Learning... KUDOS!

Applications and examples are well-chosen. The choice of theory is appropriate given the audience. The problem sets are a tad on the difficult side in that extreme care must be taken to get the right answers. Some of this has to do with how the assignments are structure. Instructions need to be read several times, which can be quite tedious. In the end, they help you learn the material and force you to implement carefully.
