Amazon SageMaker is a fully managed service that enables developers and data scientists to build, train, and deploy machine learning (ML) models quickly. It provides algorithms, notebooks, APIs and scalable infrastructure for building ML models. Some key features of SageMaker include algorithms for common ML tasks, notebooks for developing models, APIs for training and deployment, and scalable infrastructure for training and hosting models. It also integrates with other AWS services like S3, EC2 and VPC.
This document discusses clustering and anomaly detection in data science. It introduces the concept of clustering, which is grouping a set of data into clusters so that data within each cluster are more similar to each other than data in other clusters. The k-means clustering algorithm is described in detail, which works by iteratively assigning data to the closest cluster centroid and updating the centroids. Other clustering algorithms like k-medoids and hierarchical clustering are also briefly mentioned. The document then discusses how anomaly detection, which identifies outliers in data that differ from expected patterns, can be performed based on measuring distances between data points. Examples applications of anomaly detection are provided.
The document discusses hyperparameter optimization in machine learning models. It introduces various hyperparameters that can affect model performance, and notes that as models become more complex, the number of hyperparameters increases, making manual tuning difficult. It formulates hyperparameter optimization as a black-box optimization problem to minimize validation loss and discusses challenges like high function evaluation costs and lack of gradient information.
