Session: Optimizing Machine Learning-Based Detection Systems
Detection systems are one of the industry's most profitable and widely used types of machine learning solutions. Therefore, its proper deployment is of extreme importance for a wide range of applications. Detection systems face several challenges when the data presents a highly imbalanced class distribution. In this talk, Gissel Velarde will share seven key points to achieve optimal performance in real-world detection problems for binary classification. She will describe relevant tasks that include understanding the business use case, exploring the data, exploring previous solutions, preparing the data, optimizing hyperparameters, evaluating performance, and finally, getting feedback from the end users.Key Takeaways
