Model Builder

Training is an automatic process by which Model Builder teaches your model how to answer questions for your scenario. Once trained, your model can make predictions with input data that it has not seen before. For example, if you are predicting house prices and a new house comes on the market, you can predict its sale price.

The default metric for value prediction problems is RSquared, the value of RSquared ranges between 0 and 1. 1 is the best possible value or in other words the closer the value of RSquared to 1 the better your model is performing.

Other metrics reported such as absolute-loss, squared-loss, and RMS loss are additional metrics, which can be used to understand how your model is performing and comparing it against other value prediction models.

The default metric for classification problems is accuracy. Accuracy defines the proportion of correct predictions your model is making over the test dataset. The closer to 100% or 1.0 the better it is.

Balance your data. For classification tasks, make sure that the training set is balanced across the categories. For example, if you have four classes for 100 training examples, and the two first classes (tag1 and tag2) are used for 90 records, but the other two (tag3 and tag4) are only used on the remaining 10 records, the lack of balanced data may cause your model to struggle to correctly predict tag3 or tag4.

After the evaluation phase, Model Builder outputs a model file, and code that you can use to add the model to your application. ML.NET models are saved as a zip file. The code to load and use your model is added as a new project in your solution. Model Builder also adds a sample console app that you can run to see your model in action.

Achieve a multi-model view of risk with a unified risk management workflow in Touchstone. Aggregate loss metrics from custom models and Verisk models across your portfolios, then roll up the results into your own custom view of risk.

Instead of running each tool one by one, you create a model that takes your input, transforms it with a series of tools, and then outputs it. In other words, ModelBuilder connects your input to geoprocessing tools and transforms it into your desired output.

Another way to save you time is to use ModelBuilder and create a model for your workflow. Once you get the model working, then export the model as a script (Model > Export > To Python Script). The output of this export provides a great starting point where you can alter the Python code and even include other Python packages.

Geometric entities such as material domains and surfaces can be grouped into selections for subsequent use in physics definitions, meshing, and plotting. Additionally, a sequence of operations can be used to create a parametric geometry part, including its selections, which can then be stored in a Part Library for reuse in multiple models.

The import of all standard CAD and ECAD files into COMSOL Multiphysics is supported by the CAD Import Module and ECAD Import Module, respectively. The Design Module further extends the available geometry operations in COMSOL Multiphysics. Both the CAD Import Module and the Design Module provide the ability to repair and defeature geometries. Surface mesh models, such as in the STL format, can also be imported and then converted to a geometry object by the COMSOL Multiphysics core package. Import operations are like any other operation in the geometry sequence and can be used with selections and associativity for performing parametric and optimization studies.

The COMSOL software contains predefined physics interfaces for modeling a wide range of physics phenomena, including many common multiphysics couplings. Each physics interface provides specific settings dedicated to the associated scientific or engineering field. Upon selection, the software suggests available study types, such as time-dependent or stationary solvers. Once chosen, the appropriate numerical discretization of the mathematical model, solver sequence, and visualization and results settings are implemented. All of the settings are, of course, editable for the user to manipulate.

The COMSOL Multiphysics platform is preloaded with a large set of core physics interfaces for fields such as solid mechanics, acoustics, fluid flow, heat transfer, chemical species transport, and electromagnetics. By expanding the core package with add-on modules from the COMSOL product suite, you gain access to a range of more specialized user interfaces with modeling capabilities suited to specific engineering fields.

To really be useful for scientific and engineering studies and innovation, a software has to allow for more than just a hardwired environment. It should be possible to provide and customize your own model definitions based on mathematical equations directly in the user interface. The COMSOL Multiphysics software offers this level of flexibility with its built-in equation interpreter that can interpret expressions, equations, and other mathematical descriptions on the fly before it generates the numerical model. Adding and customizing expressions in the physics interfaces allows for freely coupling them with each other to simulate multiphysics phenomena.

The capabilities for customization go even further. With the Physics Builder, you can also use your own equations to create new physics interfaces for easy access and manipulation when you want to include them in future models or share them with colleagues.

For discretizing and meshing your model, the COMSOL Multiphysics software uses different numerical techniques depending on the type of physics, or the combination of physics, that you are studying. The predominant discretization methods are finite-element based (for a complete list of methods, see the solvers section of this page). Accordingly, the general-purpose meshing algorithm creates a mesh with appropriate element types to match the associated numerical methods. For example, the default algorithm may use free tetrahedral meshing or a combination of tetrahedral and boundary-layer meshing, with a combination of element types, to provide faster and more accurate results.

When you select a physics interface, a number of different studies (analysis types) are suggested by COMSOL Multiphysics. For example, for solid mechanics analyses, the software suggests time-dependent, stationary, or eigenfrequency studies; for CFD problems, the software would only suggest time-dependent and stationary studies. Other study types can also be freely selected for any analysis that you perform. Study step sequences structure the solution process to allow you to select the model variables for which you want to solve in each study step. The solution from any of the previous study steps can be used as input to a subsequent study step.

Any study step can be run with a parametric sweep, which can include one or multiple parameters in a model, from geometry parameters to settings in the physics definitions. Sweeps can also be performed using different materials and their defined properties, as well as over lists of defined functions.

Using the Optimization Module, you can perform optimization studies for topology optimization, shape optimization, or parameter estimations based on a multiphysics model. COMSOL Multiphysics offers both gradient-free and gradient-based methods for optimization. For parameter estimation, least-squares formulations and general optimization problem formulations are available. Built-in sensitivity studies are also available, where they compute the sensitivity of an objective function with respect to any parameter in the model.

Phillips became a master model builder five years ago. LEGOLAND Florida hired him in 2011 when the park opened. He's on the team that designs and builds what you see throughout the park, from holiday displays to the cityscapes of Miniland.

If you'd like to learn at the hands of the masters, LEGOLAND Florida Resort offers Master Model Builder sessions, available with hotel stays. You can also get a tour of the model shop during a VIP Experience Tour.

I have created a model tool for Select by location (See the attachment). The idea is to select and export parcels within certain radius of another parcel. The tool works great in Desktop but I am having hard time using it as a Geoprocessing Widget in Web Application.

When you are building your model just don't assign a data source to it. Leave it blank. If you need to reset the model just click on the "Validate" button on the model builder toolbar (it's a checkmark) that should reset anything that was holding over from a previous run.

Inheritance Assembly consists in filling current model empty fields with values taken from parent model. It is done in InheritanceAssembler (javadoc), with its DefaultInheritanceAssembler implementation (source).

Notice that the 5 URLs from the model (project.url, project.scm.connection, project.scm.developerConnection, project.scm.url and project.distributionManagement.site.url) have a special inheritance handling:

Notice that model interpolation happens after profile activation, then profile activation doesn't benefit from every values: interpolation for file-based activation is limited to $basedir (which was introduced in Maven 3 and is not deprecated in this context), system properties and user properties.

IBM Model Builder is an AI training platform that uses the capabilities of IBM Cloud and its GPUs to quickly train computer vision models for compatible mobile apps. IBM Inspection Workbench iPadOS app is the exclusive user interface for labeling, along with training and deploying models.

Treelite supports loading models from major tree libraries, such as XGBoost andscikit-learn. However, you may want to use models trained by other treelibraries that are not directly supported by Treelite. The model builder isuseful in this use case. (Alternatively, considerimporting from JSON instead.)

Let us construct this ensemble using the model builder. First step is toassign unique integer key to each node. In the following diagram,integer keys are indicated in red. Note that integer keys need to beunique only within the same tree. 041b061a72
