Trend Reports

Trend Report

Enterprise AI

In recent years, artificial intelligence has become less of a buzzword and more of an adopted process across the enterprise. With that, there is a growing need to increase operational efficiency as customer demands arise. AI platforms have become increasingly more sophisticated, and there has become the need to establish guidelines and ownership.In DZone's 2022 Enterprise AI Trend Report, we explore MLOps, explainability, and how to select the best AI platform for your business. We also share a tutorial on how to create a machine learning service using Spring Boot, and how to deploy AI with an event-driven platform. The goal of this Trend Report is to better inform the developer audience on practical tools and design paradigms, new technologies, and the overall operational impact of AI within the business.This is a technology space that's constantly shifting and evolving. As part of our December 2022 re-launch, we've added new articles pertaining to knowledge graphs, a solutions directory for popular AI tools, and more.

Predict Customer Churn Using R and Tableau

HI Kriti, Depends on the R package you are using for modeling. Generally, it does not and you have to do the required transformations manually. There are many methods such as one hot encoding to transform categorical variable before creating an ML model. However, now a days we have certain R packages such as H2O which does this for you. Hope this helps. Thanks.
