Rapidminer gui manual

When changing the default, it should never exceed 2 times the number of CPU cores though, otherwise operators may become significantly slower due to additional management overhead. Note: Increasing this setting above your license's logical processors limit has no effect.

The number of nominal values to use…. The number of nominal values to use for meta data transformation, 0 for unlimited. Changing this value requires a cache refresh of the meta data for the current process, e. Fall back to the legacy data manage…. Fall back to the legacy data management deprecated with RapidMiner 7. Please note that support for this mechanism will be removed from future versions of RapidMiner.

If you encounter a problem that requires the legacy data management, please contact our support. Select the authentication mechanism…. Select the authentication mechanism to use.

Used for email notifications. Range: Standard fonts, System fonts…. Fonts used in the RapidMiner user i…. Fonts used in the RapidMiner user interface. It is recommended to keep the default setting unless you experience incompatibilities with non-western characters.

RapidMiner Studio needs to be restarted for the changes to take effect. Standard fonts Use the recommended default fonts. Custom fonts Replace all fonts with a custom font. Select which proxy should be used. System Uses the proxy configuration of the operating system. Direct No Proxy Bypasses all proxies system and manual.

Manual proxy configuration Uses the proxy configuration entered in the fields below. On Windows and Linux empty settings fall back to the existing system settings. List of hosts that should be reache….

List of hosts that should be reached directly, bypassing the proxy. This is a list of patterns separated by ' '. Any host matching one of these patterns will be reached through a direct connection instead of through a proxy. Example: localhost This activates a detailed scan of e…. This activates a detailed scan of each repository on start-up to add more search capabilities, e. This can take a lot of time for very large repositories. Requires a restart to take effect.

All rights reserved. Unix log file highlighting Use unix special characters for logfile highlighting requires new RapidMiner instance. Debug mode Run RapidMiner in debug mode Print exception stacks and shows more technical error messages. Don't abort process if learner capabilities not satisfied Show only a warning message, if learning capabilities are not fulfilled rather than aborting the process.

The goal of the use case was to analyze POS data and detect fraud. We wanted an easy way to load the data from the server and write calculated identifiers back. The analysis of the data was easy and fast, thanks to the very successful interface in RapidMiner. Auto Model made it quick and easy to extend the analysis to other areas of applications. The excellent results speak for themselves, so we have been very satisfied with our cooperation with RapidMiner for a long time.

The support is remarkable and leaves nothing to be desired. RapidMiner Studio is an awesome tool! It really speeds up the data exploration process and provides a firm foundation for building machine learning models. The support staff is excellent! They really helped me and my team build and prove out our use case to put into production. They also helped us integrate seamlessly with Tableau, which was critical for our user group.

Using the software to understand and control process variation within our mills is working very well. Citizen data scientists have adapted to using the software very quickly, resulting in many projects being implemented at a mill level. Integrating our previous open source machine learning solutions R and Python in the RapidMiner platform was seamless. RapidMiner Studio represents an efficient balance between, on the one hand, an intuitive interface with a streamlined workflow and, on the other, access to a broad suite of sophisticated, underlying models and data handling routines.

This balanced design can only have been brought to market by developers who truly understand the modern data science workflow. This gives you the performance of a local repository when working with it during prototyping, but also allows for easy collaboration with your colleagues. Added new panel "Snapshot History" which allows to browse the history of your versioned projects, as well as see the changes you've made since the latest snapshot.

It can also be used to restore an earlier state of the project, view past versions of individual files, and to restore those past versions.

ExampleSets are now written to disk in a new file format: HDF5. This is a well-established format used e. Local repositories that will be created with RapidMiner Studio 9. New operator Target Encoding which can remove nominal attributes with too many values and performs a target encoding also known as mean encoding on the remaining attributes Auto Model: some processes e.

Benefits include: Enhanced throughput and performance Better meta data caching Concurrent access support Displaying all files no matter what they are, e. Python scripts, images, Allowing different file types e. If you create a new local repository, it will have Local after its name and have all the capabilities listed above.

You can copy your data over via Studio from the old repository to a new one to migrate. It is now possible to have a folder with the same name as a data entry in the repository might not work for some old repositories It is now possible to have a process and a data entry with the same name in the repository might not work for some old repositories Replaced Send Mail operator with new version which supports file attachments Improved memory usage for Aggregate and Pivot operators for nominal columns with potentially a lot of unused values Improved dealing with whitespaces in repository entry names Improved cleanup of temp files, to reduce disk space clutter when Studio runs for a long time, i.

Added the option to specify negative lags for the Lag operator Added the option to specify a default lag for a set of attributes selected by an attribute subset selector to the Lag operator Unfortunately due to parameter key incompatibilities, old version of the Lag operator is deprecated and new version with the same name, but different operator key is added.

H2O Updated H2O library to version 3. Added monotonicity constraints to Gradient Boosted Trees Added weights port to Deep Learning Expanded whitelist of accepted expert parameters, now supports all parameters provided by H2O Deep Learning and Logistic Regression now work with datasets that have nominal columns with only one value Bugfixes Fixed an issue that could cause Studio startup to never complete Made Studio startup more rigid to quit process instead of silently hanging on the splash screen forever Fixed issue that could cause panels to sometimes not open if they had been closed previously in this session Fixed an issue that caused CTAs not working when HTML5 safe mode was enabled Fixed an issue with back propagation of changes to performance vectors Fixed a problem for JDBC drivers that do not implement a certain set of functionality by adding a fallback e.

SQLite writing Fixed potential cause for complete UI freeze when interacting with a CTA notification banner Fixed an issue with process navigation and property panel if operator names contain HTML Generate Multi-Label Data does now correctly work in non-regression mode Fixed memory leak caused by the Visualizations Fixed rare issue where data sets could not be downsampled automatically if license limit was exceeded Fixed an issue in Automatic Feature Engineering if all input features have been nominal in the feature selection case Fixed "Edit Access Rights" dialog for Server repositories not getting the permissions correctly when using Enterprise SSO Fixed an issue that caused Studio to lag and increase memory consumption when using the right-click "Insert operator" popup menu in the Process panel.

Special notes Columns of type "Integer" that were previously stored as integers are now stored as their double representation. This might have an impact when storing data to disk and rereading it. Columns of type "Date" no longer store the milliseconds due to the new file format. This might have an impact of equality tests and matching when storing data to disk and rereading it. Visualizations that have been created locally for data sets stored in repositories will not be found anymore after the update, causing the result visualization to reset to its default.

If you have set up complex visualizations that you absolutely want to restore, you can follow these steps: Open the data set in the Results view of RapidMiner Studio. There you can find a folder structure matching your repository names and structure. Find the exact path to the data set e. Pie" You should see a very similar path right next to it, either ending in ".

It should now have its configuration back! Repositories now distinguish between data and folders, and even between different data subtypes process, ioobject, connection, binary entry which means you can have a folder called "A" and e. This has implications for a large number of APIs, most notably: com. This is used for the new file-based repository implementations Local and versioned Project that will ultimately have different file suffixes on disk for every distinct IOObject type instead of all of them sharing the legacy.

This is used to hide temporary repositories from the repositories panel and from the Global Search if true.
