Case Studies: Analyzing Sentiment & Loan Default Prediction
In our case study on analyzing sentiment, you will create models that predict a class (positive/negative sentiment) from input features (text of the reviews, user profile information,...). In our second case study for this course, loan default prediction, you will tackle financial data, and predict when a loan is likely to be risky or safe for the bank. These tasks are an examples of classification, one of the most widely used areas of machine learning, with a broad array of applications, including ad targeting, spam detection, medical diagnosis and image classification.
In this course, you will create classifiers that provide state-of-the-art performance on a variety of tasks. You will become familiar with the most successful techniques, which are most widely used in practice, including logistic regression, decision trees and boosting. In addition, you will be able to design and implement the underlying algorithms that can learn these models at scale, using stochastic gradient ascent. You will implement these technique on real-world, large-scale machine learning tasks. You will also address significant tasks you will face in real-world applications of ML, including handling missing data and measuring precision and recall to evaluate a classifier. This course is hands-on, action-packed, and full of visualizations and illustrations of how these techniques will behave on real data. We've also included optional content in every module, covering advanced topics for those who want to go even deeper!
Learning Objectives: By the end of this course, you will be able to:
-Describe the input and output of a classification model.
-Tackle both binary and multiclass classification problems.
-Implement a logistic regression model for large-scale classification.
-Create a non-linear model using decision trees.
-Improve the performance of any model using boosting.
-Scale your methods with stochastic gradient ascent.
-Describe the underlying decision boundaries.
-Build a classification model to predict sentiment in a product review dataset.
-Analyze financial data to predict loan defaults.
-Use techniques for handling missing data.
-Evaluate your models using precision-recall metrics.
-Implement these techniques in Python (or in the language of your choice, though Python is highly recommended)....

Hats off to the team who put the course together! Prof Guestrin is a great teacher. The course gave me in-depth knowledge regarding classification and the math and intuition behind it. It was fun!

Very impressive course, I would recommend taking course 1 and 2 in this specialization first since they skip over some things in this course that they have explained thoroughly in those courses

This course is friendly to machine learning beginners for the learning material is easy to understand as well as the assignment is easy to accomplish.

It is very intuitive and easy to follow.

I hope you add SVM and talk about linear/nonlinear decision boundaries in the next enhancement to the course.

While I enjoyed most of the exercises, I found some of the implementations to be more puzzle solving rather than deeply understanding the algorithms.

The course has be described in a very precise manner. The instructor takes time to clearly explain the concepts and the importance of the same.

The best machine learning course I took online. I've taken other coursera courses, and this is the most complete, comprehensive, and well made.

Great course. The lectures and programming assignments have been extremely beneficial to help me get a basic foundation of ML classification.

This course is alright. For some reason I liked the regression course more as this one was a little to simple in terms of the practical.

Course is really good. Assignments are taking too much time if you want to do the course rally fast, with questionable learning value.

Excellent course and all the concepts have been explained very simply and with an element of fun.

Many thanks to Emily and Carlos...

Would have loved even more had Carlos explained his students gradient boosting as well. I liked the way of his taught in lectures.

Loved the way our tutor (Carlos) explained the concepts to us. Things are getting clearer with each course in ML :) Many thanks :)

All the basics - and much of the advanced stuff - is presented, in a coherent and inspired way. Thanks for crafting such a course.

Good course with many assignment to design the algorithm with your own code. But I think this course last a little bit too long.

Great! Not horribly wretchedly awful, but actually very good! (With this class I hope this is classified correctly!)

It was a very detailed course. I wished, doing it much earlier in my research career. Great insights and Exercises.

very interesting and novice friendly, however some math (basic matrix calculus and derivatives) review worth doing
