![]() To specify communication between the operators, we set the implementation and parameters of the process. At the bottom of the middle panel are the tips – based on processes built by other users, RapidMiner provides you there with recommendations regarding the use of operations. At the right panel you can see the detailed record parameters and operation principles of the selected operator. The central part of the screen is the workspace to create a data conversion process. Using drag and drop we can add, change or remove, the data sources and the operators for data conversion, to or from our process. It is possible to add new operators with the ever-growing RapidMiner Marketplace. For example, among the available extensions there is an operator that converts data sets into time series. ![]() Those are the main categories, each of which has its own subcategories and variations of operators. ![]() auxiliary operators (run Java and Groovy-routines, data anonymization, sending e-mail messages, event planner).mathematical modeling operators (predictive models, cluster analysis model optimization models).operators to work with attributes (transformation of types, dates, set operations, etc).access to the data (job files, databases, cloud storage, Twitter streams, Salesforce).On the left side of the screen you can see a data and process repository panel and the operators. RapidMiner provides the ability to load data or processes from a database or cloud storage (Amazon S3, Azure Blob, Dropbox ).įor convenience, Operators are divided into categories: The data set you can find here: and try to ask the aforementioned questions. Let’s analyze the data set from statistical office Munich with monthly figures of traffic accidents. This decrease may have several causes: technological more advanced cars, modern security measures in and around the vehicles, better road quality, speed limits, seat belt usage required by law, lowering the alcohol limit and others. But which of these innovations are the most effective? Is there any correlation between year, month and amount or art of car accidents? Is it possible to predict the car accidents amount in next period? The record year marks 1970: 19.193 people died in traffic, more than half a million were injured and sadly many of them remained crippled. To date, the number of car accidents in Germany has steadily declined almost every year. First steps with RapidMinerįrom 1950 to 2015 over 696,226 people lost their lives on German roads. The server has a Web-Interface to manage connections to data sources and giving details of the miner processes. On top of that RapidMiner is a complete tool for ETL processes.īesides the more than the 400 analytic functions, there is also the RapidMiner Server, which can be used as a (Cloud) repository for storing and executing miner processes (including a schedule). They can also obtain and process information from various sources, for example: databases, local files, etc. To make the data mining process more transparent and smooth, it has a good set of predefined operators solving a wide range of problems. A tool created for data mining, with the basic idea, that the analyst does not require to have good programming skills. ![]() There is a distinctive lack of open source solutions for data mining and data analytics, but one of the most decent, efficient and free, software solutions is RapidMiner Studio. The high costs, lack of experience and, in most cases, the excessive complexity of the software on hand and high costs for employee training, maintaining expensive data processing and storage systems on the other, forcing them to abandon the idea of building their own analytical system, in favor of a much simpler Excel-based solution. Nowadays many companies are in need of system analysts. This volume increase of data, brings new challenges for analysts and specialists, working on optimization of business tasks. The pace of development in the global economy is increasing, but a quick response to changes on the micro level allows individual companies to expand. And to aid that, there are tools for data analysis and machine learning. This trend can be clearly seen in the steady growing IoT, but also other industries can access a huge range of data sources – free public or private available for a subscription fee. The amount of data being created and harvested by organizations and private individuals is growing exponentially.
