Course OVERVIEW
Description
CPE Credits: 7.5
Field of Study: Information Technology
Delivery Method: QAS Self Study
Delivery Method: QAS Self Study
Data science education focuses too much on the algorithm itself. In reality, we can have only four lines of code and use them for a variety of problems. The heavy lift of an ML model is the end-to-end process. Jeff Li and Ken Jee walk you step-by-step through this process, so you can successfully take your next project from start to finish. You will learn everything you need to know to set your projects up for success. The Machine Learning Process A-Z course gives you a deep understanding of what machine learning really is. It helps you understand when you should and shouldn’t use this powerful tool. Jeff and Ken break down the specifics of the different problems you can encounter and how machine learning is used in specific domains. In the second part of the course, you will learn the entire modeling process. Jeff and Ken show you how to pull real results and make the ML model work for others, not just yourself. You will learn how to perform essential steps like data preprocessing. In this section, they also show you how to deal with null values and outliers. Next, you’ll see how to explore your data to frame your analysis. Additionally, the course deals with some of the visualization techniques that can help you to see the relationships in your data. After that, we go into feature engineering—one of the most important steps for improving your model’s results. That leads to cross-validation and how to handle bias and variance trade-off in your analysis. Finally, the instructors touch briefly on the model tuning process and how to productionize your work and documentation.

- 2. Intro to Machine Learning15 min15 minLearn when you should and shouldn’t use machine learning. We teach you when in your organization’s lifecycle to implement ML and what real-life problems you can solve. We also cover the types of ML problems and show you the difference between product analytics vs. data products.
- 3. The Modeling Process8 min8 minThe most important step in machine learning is not any fancy technique—it’s properly defining the problem. An incorrect definition can result in months—or even years—of wasted resources. That is why, before we can leverage the power of ML, we need a reason to use it. Whether it’s a directive from a manager, a pain point from a stakeholder, or a gap in the business, you need to properly frame the problem first and foremost.
- 4. Data Collection8 min8 minMost projects won’t give you the data in a neat and tidy .csv file like they do in class or on Kaggle. If you work at a big company, it is likely that you will have plenty of data readily available to you. However, you’ll still need to pull it yourself. In this section, we will talk about data collection techniques from most structured to least structured.
- 5. Data Preprocessing35 min35 minAfter defining our problem, we need to preprocess our data. Keep in mind that different models have different requirements. For example, linear regression cannot handle null values, whereas some tree-based models can. Additionally, deviant data points can significantly skew the results of some models and not others, e.g., linear models are affected by outliers whereas tree-based models—not as much. In that case, you may want to remove or adjust outliers in order to get the best performance from our models. After all, we want to make sure our data is of the highest quality before we start building our models.IntroDealing with null valuesTypes of null valuesMissing values - Coding examplesMissing values - Coding portionStrategies for handling null valuesDealing with outliersOutliers - Coding portionImplications of outliersDetecting outliersCauses of outliersTreating outliersOutliers - Coding examples
- 6. Exploratory Data Analysis for ML52 min52 minExploratory data analysis is an important prerequisite to the modeling process. With EDA, we get a feel for the assumptions so we can choose the best model and get the most accurate results. The reason we perform this step is to understand the shape of our data and the relationships between the variables.OverviewWhy you need EDAHow to approach EDADistributions and single variable plotsRelationships and multi variable plotsScatterplotsCorrelationCorrelation matrixBar chartsLine chartsPivot tableHow to generate useful insightsBasic EDA - Coding examplesBasic EDA - Coding portion (1 of 2)Basic EDA - Coding portion (2 of 2)
- 7. Feature Engineering44 min44 minThe feature engineering step will likely reap the highest accuracy gains in our modeling process—even more than the selection of the algorithm itself. The core principle is to find variables that have predictive power. So, regardless of how complex the feature is or how fancy of a technique, if it does not add predictive power to our model, then it doesn’t do anything for your model. Remember: complexity doesn’t create value. Creative and domain-specific features create value.IntroCategorical featuresCategorical features - Coding examplesCategorical features - Coding portionOne-hot encodingOrdinal encodingFrequency encodingTarget encodingProbability ratio encodingWeight of evidence encodingBinningFeature engineering for continuous variablesScalingNormalizationMinMax scalingZ-score normalizationRobust scalerTypes of transformationsLogarithmic transformationsExponential transformationsSquare root transformationsBox-Cox transformationsArithmetic interactionsBinningCreative featuresContinuous feature scaling - Coding examplesContinuous feature scaling - Coding portion
- 8. Cross Validation33 min33 minCross-validation allows us to test our model on data that the model has not been trained on. If it performs well on this unseen data, we can be more confident that our predictions will generalize well.
- 9. Feature Selection18 min18 minFeature selection is the process of reducing the model’s complexity by selecting only the highest signal features in the dataset. Typically, there are three classes of feature selection techniques. Wrapper methods require us to exhaustively search through all features and measure performance. They give us the best accuracy but are the most computationally expensive out of the three. Next, we have filter methods that pick up feature properties through univariate statistics. These tend to be faster and easier to check since they don’t rely on cross-validation. Lastly, the embedded methods are baked into the ML algorithm. We cover these in the companion course, Machine Learning Algorithms.
- 10. Dealing with Imbalanced Data26 min26 minHow do we deal with imbalance in our data? This is where oversampling, undersampling, and other techniques become useful. We show you how to perform these to optimize your model’s performance.
- 11. Modeling47 min47 minIn this section of the course, we’ll focus on ML modeling techniques such as the baseline model, model selection, hyperparameter tuning, and assembling.
- 12. Model evaluation53 min53 minWe can’t measure the value of our model without proper evaluation criteria. Earlier in this course, we touched on two types of Supervised ML problems—regression and classification. Since these problems use different target variables, we use different metrics to evaluate the quality of the model.Model evaluationClassification evaluationClassification metrics - Coding examplesPrecision and RecallAccuracy, Precision, Recall - Coding portionROC curvesROC AUCF1-ScorePR-AUCClassification metrics - Coding portionLog lossRegressionRegression metrics - Coding examplesR-squared / Adjusted R-squaredMean absolute errorRoot mean squared errorRegression notebook - Coding portion
- 13. Productionization7 min7 minThe goal of our work is to make it useful to other people. How do we do that? Through something called productionization. It is a little broader than simply deploying the model into your product; rather it is the delivery of our model to our end user in whatever form.
- 14. Conclusion6 min6 minAs the course goes through different steps of the modeling process, you’re probably wondering, “How am I supposed to remember each step?” The good news is that building an ML model typically follows a very similar process each time: (1) Problem Framing/Business Understanding; (2) Data Cleaning/Preparation; (3) Exploratory Data Analysis; (4) Feature Engineering; (5) Cross-Validation; (6) Modeling; (7) Evaluation
