New Features and Enhancements 2023.0
Library Creator
The Library Creator is a GUI utility tool that helps to create, modify, and encrypt extensions. From the File Utilities ribbon, select Library Creator.


Library Creator has tabs for entering Basic Info and Optional Files for creating a Plugin.xml, loader.oml, unload.oml, and organized folders that are used as an extension.
Functions include:
- Create an extension from scratch by selecting Basic info and/or Optional.
- Create an extension from scratch by selecting Basic info and/or Optional and encrypt it.
- Load an existing extension, modify, and encrypt it.
- Load an existing extension and encrypt it.
- Encryption of python files is currently not supported.




Invoke mode
Console Invoke mode now supports Descriptionting and Visualization with '-withgui' argument.
compose_console.bat -withgui -continue -f BodeNyquistDescription.oml
Batch mode now supports creating and saving of Descriptions with '-withgui' argument. This requires a graphics card.

Redesign and enhancements of romAI Director *
New UI
A new workflow improves ease of use.


The GUI has the following sections:
1. File Menu: Contains generic actions
2. Top ribbon: Buttons based on the uipushtool feature
3. Tabs: Provide the switching feature
4. Left table: Choose signals and models
5. Canvas: Shows Descriptions
6. Left panels: Show dataset and model information
7. Right panels: Input parameters
8. File information text boxes
The Pre-Processor lets you Description, filter signals, and save data.


The Builder has the following functions:
- Arrange the parameters in tabs
- Add a table for all features that go in training
- Physical Constraints can be selected using a drop-down menu instead of writing


The Post-Processor has the following features:
- Visualize all results (Loss metrics, Accuracy Check, Hyper Planes, and Time Simulation) on a single page and with fewer clicks
- Process more than one model without loading models repeatedly


Heat Map
A Heat Map has been added to show the correlation among features. This helps you select features based on correlation coefficient. The Correlation Coefficient slider helps to get most correlated features.


Auto Exploration
Auto Exploration lets you train multiple models with different hidden layers, activation functions, and neurons.


Stop Training
To stop model training, click the Stop button.



OML
New OML Commands
CAE Readers 3D *
caereader3d now supports extraction of composite layers.
- getlayername3d, getlayerindex3d, getlayerslist3d commands extract composite layer information from CAE result file with model information.
- 'layer' argument in readcae3d can take layer information from the above commands and extract results from the composite layer.
- New caereaderoptions command is supported to set reader properties
. Supported property: 'validatetime'
.. If set to 'true' it will validate that time channel values are not same. This is the default behavior.
.. If set to 'false' it will not validate the time channel information and extract the result with NaN when there is no result.
Communicate *
The Communicate library provides commands to support various communication protocols. MQTT Communicate Protocol is supported in Compose. The library contains the following commands:
- mqttclient: Connect to MQTT broke

. min and max functions now can ignore NaN values while evaluating.
- Kronprod:
. Certain operations on a Kronecker product can be applied to A and B without computing the actual product, kron(A,B).
. The kronprod object allows this shortcut to be performed when possible.
. Provides efficiency and ease of computation power while dealing with large matrices.
- gradient function is now supported to compute gradient of a function or sampled data.
- histc computes histogram counts.
Descriptionting

Python OML bridge
- table class now can be mapped to pandas DataFrame.
- Python Object Class mapping to OML object class
Signal Processing
- filter2: Performs 2D FIR filtering.

Altair Simulation-driven design changed product development forever, enabling engineers to reduce design iterations and prototype testing. Increasing scientific computing power expanded the opportunity to apply analysis, making large design studies possible within the timing constraints of a program. Now engineering adoption of AI is transforming product development again. The combination of physics-based simulation-driven design with machine learning, leveraging the latest in high-performance computing, enables teams to explore more and identify high-potential designs - while rejecting low-potential concepts - even earlier in development cycles.
Composeis an environment for doing math calculations, manipulating, and visualizing data, programming, and debugging scripts useful for repeated computations and process automation. Compose allows users to perform a wide variety of math operations including linear algebra and matrix manipulations, statistics, differential equations, signal processing, control systems, polynomial fitting, and optimization. The broad set of native CAE and test result readers accelerates system understanding and works with Altair Activate to support model-based development, for multi-domain and system of systems simulations. Altair Embed completes the model-based design portfolio with automated code generation, allowing for the testing and verification of embedded systems.
Altair Compose: Introduction to Signal Processing
Using Compose for Signal Processing allows useful information to be extracted from sensors that cannot be measured, can improve transmission, storage efficiency, and quality of signal. It will help you have a more clear understanding of phenomena in many applications. The "Signal Processing" playlist has been organized in 13 modules covering amongst others fundamentals, file i/o, frequency domain as well as time domain analysis.
