The most exciting new feature is the tight integration of Meta's Segment Anything 2 model for annotating images (object detection and image segmentation) thanks to the Deep Java Library project (DJL). You no longer have to launch a Docker image through a separate flow in the background in order to take advantage of the model. See this video for Segment Anything 2 in action: https://youtu.be/5ln2c2kgMAc

Are you a Windows user trying to open a file from a directory with lots of files in it?

It seems that there has been a regression in OpenJDK since the 11 LTS release that turns the JFileChooser component unusable for directories with 100s or 1000s of files when using a Look'n'feel other than the cross-platform one, with the dialog taking several minutes to appear.

Here is a Github issue describing the problem:

https://github.com/JFormDesigner/FlatLaf/issues/953

Up till recently, ADAMS only used the cross-platform one, but switched to Flatlaf for its sleek, modern look. Currently, we are waiting for the 3.6 release of the FlatLaf Look'n'feel to be made available, which addresses this issue for Windows users.

In the meantime, you can switch to the cross-platform Look'n'feel from the main menu as follows:

Program > Look'n'feel > Cross-platform

And then restart ADAMS for the changes to take effect.

Wide range of fixes, changes and additions. Notably are the addition of basic git support in the Flow editor (to be enabled in the Preferences dialog) and support for the H2 SQL database (e.g., for adhoc, in-memory use). Also, Weka's evaluation can be interrupted now a bit better, e.g., between cross-validation folds and while evaluating a classifier. Some ADAMS-only classifiers received an overhaul to allow interrupting their build process as well. The adams-nlp module has been retired, due to security concerns of some of its third-party libraries and the amount of work that would have been required to keep it going.

  • disambiguating tab titles now in the Weka Investigator to avoid confusion in the logs

• adams-xml: upgraded xstream to 1.4.21 to address CVE-2024-47072

Additions

• adams-git: new module with basic support for add/commit/pull/push in the Flow editor (needs to be disabled first via the preferences dialog).

• adams-spectral-2dim-core: added the PredictionErrorIQR post-processor algorithm that removes rows from the data which prediction errors are above the upper threshold based on the prediction IQR.

Retired

• adams-nlp module

Apart from a lot fixes, changes and additions, a lot of work has gone into replacing deprecated code. Since Java has been changing more rapidly since Java 9, quite a lot of code needed tweaking. Subtle changes between Java versions (e.g., ordering in Properties) were breaking the regression unit tests. In some cases, I had to resort to Java-version specific test output to compare against. But most importantly, ADAMS now successfully compiles, executes its tests and runs under the following Java versions: 11 (LTS), 17 (LTS), 21 (LTS), 22 and 23. Code base and compiled output are still targeting Java 11.

Fixes

• adams-imaging: The PolygonPointAnnotator now plots a small circle or a line when there are only one or two points selected before plotting a polygon.

• adams-compress: The GUNZIP, UnBzip2 and UnTar transformers now decompresses the data till they reach the end-of-file, handling concatenated streams now correctly.

• adams-spectral-2dim-core: improved performance of the BulkSampleDataDbWriter by fixing the underlying

  SampleDataT code (auto-commit was always on regardless of parameter).

• adams-weka and adams-weka-lts: Instances tables now apply numeric filters to numeric values correctly.

Changes

• The FlatLaf* look'n'feel themes now show scrollbars again.

• The ViewDataClickAction of the SequencePlotter and SimplePlot sink now allows the user to select the outline of a polygon and display the data points that fall within that polygon. The polygon is defined (invisible unless the PolygonSelectionPaintlet overlay paintlet is specified) by SHIFT+left-click on vertices and SHIFT+right-click to finalize the polygon (CTRL+right-click discards any points).

• The WaitForFile transformer now uses the file use check class hierarchy.

• The Storage debugging panel in the Flow editor now can copy the name/cache to the clipboard via the right-click popup menu, as well as editing and exporting.

  • The RowWiseSpreadSheetSampleDataReader now has support for row filtering.

• adams-spreadsheet:

  • Added chunking support to FastCsvSpreadSheetReader

  • Added support for running garbage collection in Spreadsheet file viewer when closing sheets/pages (File / GC on close).

  • The Unique values column operation now opens a modeless text dialog, enabling multiple dialogs to be open at the same time.

  • Spreadsheet tables now limit the number of characters that are displayed in the title (default: 40) to avoid overly wide columns. That can be adjusted with key "SpreadSheetTableMaxColumnNameChars" in GUIHelper.props.

• adams-spectral-2dim-core:

  • Added the MultiColumnSpreadSheetSampleDataReader reader for sample data, which reads reference data row-wise, using the specified column range.

  • Added the BulkSpectrumDbWriter transformer to make bulk imports of spectra faster. The recommended setting is to use a new connection and to turn auto-commit off, to dramatically increase throughput.

• adams-spreadsheet:

  • The Overlay multi-spreadsheet operation combines multiple sheets into a single one by overlaying non-empty cells at the same coordinates, with the last non-empty cell overwriting any prior content.

Have a good weekend!

Quite a few changes this time round: a number of libraries have been upgraded to address security vulnerabilities (which may or may not apply), Weka's repeated cross-validation which was recently added to the Weka Investigator is now available in the flow as well, module adams-jep was added to allow executing Python scripts from within flows, thanks to the jep project.

Additions

• adams-compression: Added the TarExport multi-object export plugin, in addition to the existing ZipExport plugin. The export supports automatic compression based on the file extension being used, e.g., gzip (.tar.gz) or bzip2 (.tar.bz2).

• adams-jep: new module for running Python scripts via Jep (https://github.com/ninia/jep/) from within ADAMS. Requires ADAMS to be started from the shell with the correct Python environment. When running flows in parallel, the user needs to ensure that the variable names do no interfere due to global scope. Video demonstrating the use of jep: https://www.youtube.com/watch?v=26WiGDN_-KA

• adams-weka and adams-weka-lts:

  • Added support for repeated cross-validation to the flow with the transformers WekaRepeatedCrossValidationEvaluator and WekaRepeatedCrossValidationOutput.

  • Added support for the Weka Package Manager in the flow with the WekaPackageManagerAction standalone/source/transformer actors and the WekaPackageToMap conversion.

This time round, there have been a bunch of important bug-fixes and additions. The Weka Investigator can now perform repeated cross-validation, calculating statistics across the runs (the Experimenter does this per fold, the Investigator per full CV) and also a new tab for executing an experiment run on the current dataset and the chosen classifier.

Last, but not least, ADAMS turned 15 today (first commit in 2009). :-)

  • Added an Experiment tab to the Weka Investigator for evaluating single classifier on selected dataset. See this video: https://youtu.be/bVid9WrpE0s?si=KJcyUT33RbGiVF89

A lot of library upgrades happened again. Most notably are the introduction of quick actions in the Flow editor that can be invoked via SHIFT+right-click or SHIFT+F10. These are actor-specific actions like changing the variable name/value of a SetVariable actor or editing the boolean condition of an actor. These quick actions avoid having to go through the full-blown GenericObjectEditor dialog, saving a few mouse clicks. The ArrayProcessor received experimental parallel execution support. Items added to queues can have a delay in msec added to them, making them available at the other only once the delay has passed.

Fixes

• adams-core:

  • The Percentage generator for the ArraySubsetGenerator transformer now works as expected; added ability to oversample as well.

  • The SQL.tableExists method now works correctly with the newer MySQL JDBC driver (limiting DB meta-data to a particular database does not seem to work anymore, as it iterates over ALL databases).

  • Fixed the exception that occurred when selecting "Use default" from the popup menu in the GOE for an array property.

• adams-docker: The management interfaces for Docker containers and images now gather the output from all commands rather than just the last one.

  • Reworked the notes support for files in the Preview browser, associating notes now with directory and file, allowing the user to edit the notes.

  • The Preview browser now has a Send to sub-menu in the popup menu for the local files as well, not just from the main menu.

  • CallableX actors no longer call the wrapUp()/cleanUp() methods of their referenced actor, as this should happen already.

Since 2012, ADAMS has hosted its release files on Sourceforge.net.

This morning, I had an email from them in my inbox, stating that I need to remove old release files as the project is way over its 5GB file quota. To be honest, I was not aware that there was a quota and I also did not see any news that they will be enforcing such a quota.

Either way, I have removed old release files and the ADAMS website is now hosting the old releases (i.e., downloads may be slower). To further conserve space, the Debian (.deb) and Redhat (.rpm) release packages have been retired as well. But you can still download current .deb/.rpm packages via the daily snapshots.

Especially in corporate or institutional environments, users typically don't have any permissions to install software. Linux users are typically familiar with installing software in their own home directory, but Windows users are often not aware that this is even possible.

ADAMS itself does not rely on an installer, all you have to do is download a ZIP file (either release or snapshot), decompress the archive and then you are good to go - as long as you have Java installed on your system.

But what if you shouldn't have Java already on your computer? No problem, you don't need admin rights in order to get Java on your computer. You can simply download a JDK, decompress the archive and set the JAVA_HOME environment variable to that directory. ADAMS automatically looks for the JAVA_HOME environment variable.

JDKs can be downloaded from here: https://adoptium.net/temurin/releases/

E.g., Java 11 for Windows 64bit (download the zip): https://adoptium.net/temurin/releases/?variant=openjdk11&os=windows&arch=x64&package=jdk

Or Java 11 for Linux 64bit (download the tar.gz): https://adoptium.net/temurin/releases/?variant=openjdk11&os=linux&arch=x64&package=jdk

Later LTS (long term support) versions like 17 or 21 should work as well, but you only need 11 as a minimum at the time of writing.

Setting environment variables under Windows:

• Windows 10: https://www.alphr.com/environment-variables-windows-10/

• Windows 11: https://www.alphr.com/set-environment-variables-windows-11/

If you are running Linux, I presume you know how to manage environment variables via the export command in your $HOME/.bashrc. config file :-)

More detailed instructions:

• Download the JDK archive from the above URL

• Decompress the downloaded archive and move the decompress directory into your home directory. At the time of writing, you would find a directory called jdk-11.0.21+9 after decompressing the archive, that is the directory to move. E.g., on a Windows machine, I would place simply in my Documents directory. On Linux, I could place it straight in my home directory.

• Copy the location of this directory onto the clipboard (e.g., for me that would be C:UsersfracpeteDocumentsjdk-11.0.21+9)

• Create the JAVA_HOME environment variable and set its value to this directory

• Download the ZIP file for the ADAMS version that you want to use (e.g., a shapshot: https://adams.cms.waikato.ac.nz/download/snapshot/)

• Decompress the ADAMS zip file and move the directory in there into your home directory. As a Windows user, this could be your Documents directory again.

That's it for the setup. You can now start ADAMS via the start_gui.bat (Windows) or start_gui.sh (Linux) script, which is located in the bin directory of your ADAMS installation.

After the release a couple of weeks ago, I spent a considerable amount of time upgrading as many dependencies as possible to address known security vulnerabilities.

Another major change is the switch to version 8.x of the MySQL JDBC driver by default (you may need to add ?sessionVariables=sql_mode='ALLOW_INVALID_DATES' to your connection string).

Last, but not least, I've upgraded a range of actors to (optionally) make use of the new JobRunnerInstance standalone actor which can be used for better managing resources (cores/memory) when running heavily parallelized flows that, e.g., train classifiers or filter data. Going through this bottleneck, it is easier to avoid starving the system of resources by limiting the number of jobs that can run in parallel.

Additions

• adams-core: The standalone JobRunnerInstance allows limiting resource intense jobs, like model training and filtering data, via a bottleneck within the actors' scope. That way heavily multi-threaded flows (e.g., nested Branch actors) won't starve the system of resources, such as CPU cores and memory. Actors implementing the JobRunnerSupporter interface can make use of that feature.

Retired modules

• adams-db-mysql8: removed as now superceded by 8.x dependency in adams-core module
