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!

I really enjoyed this course. Emily is an excellent instructor and the material was well planned and straightforward to follow. The programming assignments were useful and I got a lot out of implementing the algorithms from (near) scratch. I would have liked to see SVR and ensemble methods as part of this class but I understand they will be covered in another course. I used graphlab for all of the assignments but I also used numpy and and pandas when I couldn't find the functions I was looking for in graphlab. I was not a fan of the coursera hosted notebooks with graphlab for the first course but running it off my own machine was a different experience and I could definitely be sold on a single solution in place of numpy, pandas, and scikit learn.

This course is phenomenal! I am learning a great deal. Dr. Emily Cox is fantastic with her slides, explanation and the way she (and Dr. Carlos Guestrin) structured the course. Loving it!

This course is great. Things are very clearly explained. I am particularly happy because it helped me to understand many mathematical concepts. I will try not to be scared about formulas anymore.

Well, i took a long time to complete this, because of my academics, projects and intern. Still i recently got accelerated and completed the project with 100% grades. It has been an awesome experience to learn so much concepts under a single course.

Thanks a lot to the instructors Carlos and Emily for putting up this marvelous course. :)
