Posts tagged Classification
In machine learning, a type of problem that seeks to place (classify) a data sample into a single category or “class.” Often, classification problems are modeled to choose one category (class) out of two. These are binary classification problems. Problems where more than two categories (classes) are available are called “multiclass classification” problems. See Also binary classification model.

What is Data Classification?

Feed: Alation. Author: Jason Lim. February 10, 2022 — Data classification is necessary for leveraging data effectively and efficiently. Effective data classification helps mitigate risk, maintain governance and compliance, improve efficiencies, and help businesses understand and better use data. Let’s discuss what data classification is, the processes for classifying data, data types, and the steps to follow for data classification: What is Data Classification? Data classification is the process of analyzing and organizing structured and unstructured data into categories by tagging data based on: File type Contents Metadata Either completed manually or using automation, the data classification process is based ...

Amazon SageMaker Autopilot now provides Confusion Matrix and additional new insights for classification problems.
Feed: Recent Announcements. Amazon SageMaker Autopilot automatically builds, trains, and tunes the best machine learning models based on your data, while allowing you to maintain full control and visibility. Starting today, SageMaker Autopilot provides new metrics and reports that provide you better visibility into model performance for classification problems. You can leverage these metrics to gather more insights about the best model in the Model leaderboard. New metrics and reports include Confusion Matrix, Area under the receiver operating characteristic (AUC-ROC) curve and Area under the precision-recall curve (AUC-PR), that help in understanding false positives/false negatives, tradeoffs between true positives and false ...

If you want to read the original article, click here Decision tree regression and Classification. Decision tree regression and Classification, Multiple linear regression can yield reliable predictive models when the connection between a group of predictor variables and a response variable is linear. Random forest machine learning Introduction » finnstats Non-linear approaches, on the other hand, can perform better when the relationship between a set of predictors and a response is very non-linear and complex. Regression Trees A regression tree is a method that uses ... Read More
Binary image classification using Keras in R: Using CT scans to predict patients with Covid

Feed: Top Blog Posts. Author: Roger Max. Intent classification is also known as intent recognition is a branch of Natural Language Processing that focuses on categorizing text into various groups in order to make it easier to understand. In essence, intent classification is the act of correctly detecting natural language speech from a set of pre-defined intentions. Customer service is valued highly by many businesses. The interaction between an organization's representative and a client may be automated in order to provide better service. The majority of clients have a specific request or question in mind when they contact the company ... Read More
