Syllabus

Logistic Regression
Logistic regression is one of the most studied and widely used classification algorithms, probably due to its popularity in regulated industries and financial settings. Although more modern classifiers might likely output models with higher accuracy, logistic regressions are great baseline models due to their high interpretability and parametric nature. This module will walk you through extending a linear regression example into a logistic regression, as well as the most common error metrics that you might want to use to compare several classifiers and select that best suits your business problem.

K Nearest Neighbors
K Nearest Neighbors is a popular classification method because they are easy computation and easy to interpret. This module walks you through the theory behind k nearest neighbors as well as a demo for you to practice building k nearest neighbors models with sklearn.
Support Vector Machines
This module will walk you through the main idea of how support vector machines construct hyperplanes to map your data into regions that concentrate a majority of data points of a certain class. Although support vector machines are widely used for regression, outlier detection, and classification, this module will focus on the latter.
Decision Trees
Decision tree methods are a common baseline model for classification tasks due to their visual appeal and high interpretability. This module walks you through the theory behind decision trees and a few hands-on examples of building decision tree models for classification. You will realize the main pros and cons of these techniques. This background will be useful when you are presented with decision tree ensembles in the next module.
Ensemble Models
Ensemble models are a very popular technique as they can assist your models be more resistant to outliers and have better chances at generalizing with future data. They also gained popularity after several ensembles helped people win prediction competitions. Recently, stochastic gradient boosting became a go-to candidate model for many data scientists. This model walks you through the theory behind ensemble models and popular tree-based ensembles.
Modeling Unbalanced Classes
Some classification models are better suited than others to outliers, low occurrence of a class, or rare events. The most common methods to add robustness to a classifier are related to stratified sampling to re-balance the training data. This module will walk you through both stratified sampling methods and more novel approaches to model data sets with unbalanced classes.

Reviews summary

Well-received course on supervised machine learning classification

Learners say Supervised Machine Learning: Classification is a well-received course that largely positive reviews. Students appreciate the detailed explanations, thorough walkthroughs, and engaging assignments. The course covers a comprehensive range of topics, including classification algorithms, ensemble methods, and model explanability. Students also value the practical application through labs and assignments. However, some learners noted that the peer-review community could be more active and that the theoretical underpinnings of some algorithms could be explored further.
Labs and coding examples help reinforce learning.
"Well structured training. Lab sessions and assignments are well planned to get clarity on concepts and practical application."
"Great course and very well structured. I'm really impressed with the instructor who give thorough walkthrough to the code."
"The guided demos; although excellent, are flawed."
Course covers a wide range of classification methods.
"This course provided a very useful overview of a wide range of classification techniques using scikit-learn, including the best practice in using the techniques and theoretical underpinning of them."
"Great course, well structured. The presentation of the different methods is very clear and well separated to understand the differences."
"Excellent theoretical and practical understanding in classification algorithms."
Instructors present concepts and algorithms clearly.
"Fantastic presentations and detailed course material make this course really worth it!"
"The course is very well structured, and the explanations very clear."
"The instructor from videos is amazing. Great tutor."
Peer review feedback can be inconsistent.
"The course is very well structured, and the explanations very clear. I would only suggest enhancing the peer-review community since it takes a long time to get a review sometimes."
"Everything is satisfactory except for the peer review section. The initial submission faced challenges, primarily attributed to an unfair assessment by one of the peer reviewers."
"Very good course, full of information. The downside is that passing tests largely require very good knowledge of English."
Theoretical foundations of some algorithms could be explored further.
"The instructor was very good in drilling deep in the code snippets, explaining what every line does clearly, but on theoretic side of every algorithm, I see the handling was poor, lacks the depth and clarity, many times I looked at an external sources to understand how a model works."
"The course content is very great in the coding area and it is very helping. but a shortage that is clear is the theory behind every algorithm, the handling of it wasn't that much perfect."
"there is a lot of information with machine learning strategies and explain how to think in front of results. Super Course ! JSON files made me confusion, it mentions notebook jupiter files but not."
