Organizing Machine Learning Projects; The Crisp-DM Methodology
A widely accepted model that outlines the many processes from problem comprehension through the implementation of machine learning solutions is the Cross Industry Standard Process for Data Mining (Crisp-DM) methodology. Especially for someone with little to no prior experience working on machine learning projects, organizing a machine learning project may be quite a chore. To ensure that your project is properly planned, carried out, and managed, you can adapt a defined approach.
Organizing machine learning projects involves six steps, according to the Crisp-DM methodology:
- Business Understanding: This entails understanding the business problem, ascertaining the extent to which the problem is a problem, undergoing extensive research into possible solutions, determining whether or not a machine learning solution is necessary to solve the problem based on your understanding of the problem, identifying potential alternatives (perhaps a rule-based system), and defining a quantifiable goal. For instance, the goal for a credit risk problem could be to reduce default by 50%.
- Data Understanding: After understanding the business problem, the next step is to understand the complexity of the data provided. This includes analyzing available data sources and validating data quality i.e. is your data accurate, complete, reliable, relevant, and up to date?
- Data Preparation: Additional steps are taken to transform the data so that it is suitable for a machine learning algorithm after the quality of the data is confirmed. Some of the steps include data cleaning, transformation, feature engineering, among others.
- Modeling: Different machine learning algorithms are used on previously prepared data to select the best performing model.
- Evaluation: We assess the model’s performance and determine whether it achieves the desired outcome, among other things. We answer questions such as: how well does the model perform?, does it meet the set goal?, and so on. The model is either good enough to be deployed after evaluation, or it must go over the process again.
- Deployment: When a machine learning solution is deployed to a production environment, it is made available and usable for practical applications. This is typically done by integrating the model into a software system. Following deployment, the algorithm is continuously monitored to ensure its quality and maintainability.
It is important to note that machine learning solutions may necessitate numerous iterations. Iteration usually consists of starting simple, learning from feedback, and improving the model as required.
Following the Crisp-DM methodology allows for a well-structured project with a lower risk of failure. I hope you consider it in your next interesting project.
