Abstract: In various embodiments, a training application generates a trained encoder that automatically generates shape embeddings having a first size and representing three-dimensional (3D) geometry shapes. First, the training application generates a different view activation for each of multiple views associated with a first 3D geometry based on a first convolutional neural network (CNN) block. The training application then aggregates the view activations to generate a tiled activation. Subsequently, the training application generates a first shape embedding having the first size based on the tiled activation and a second CNN block. The training application then generates multiple re-constructed views based on the first shape embedding. The training application performs training operation(s) on at least one of the first CNN block and the second CNN block based on the views and the re-constructed views to generate the trained encoder.

Abstract: In one embodiment, a model generator generates a new model for a behavior of a system based on an existing, authoritative model. First, a mapping generator generates a mapping model that maps authoritative values obtained via the authoritative model to measured values that represent the behavior of the system. Subsequently, the model generator creates the new model based on the authoritative model and the mapping model. In this fashion, the mapping model indirectly transforms the authoritative model to the new model based on the measured values. Advantageously, the authoritative model enables the model generator to increase a rate of accuracy improvement experienced while developing the new model compared to a rate of accuracy improvement that would be experienced were the new model to be generated based on conventional modeling techniques. In particular, for a given sampling budget, the model generator improves the accuracy of the new model.

Abstract: A method and system generate a building operational performance analysis output. A synthetic data set is generated and includes a set of 3D building conceptual mass geometries. The generating includes identifying geometry types, dividing the geometry types into categories, and algorithmically generating the mass geometries using a separate workflow for each category using generative design.

The ML iteratively determines the set of features based on a measured accuracy of the surrogate model. Geometry input is received and processed through the surrogate model to generate the building operational performance analysis output which is then used to inform a designer of an approximate Energy Use Intensity of the geometry input.

Abstract: Information regarding application usage on an actor device may be provided through activity notifications and activity reports. An activity notification describing current application activity on an actor device is sent, via wireless connection, to an observer device which displays the activity notification. Activity notifications provide different granularity levels of information based on a received level selection or based on a distance (proximity) between the actor device and the observer device. An activity report representing the history of application usage on an actor device may be displayed on the actor device. For example, the activity report may be triggered to by displayed when the actor device is placed flat. The activity report provides a graphical representation of the application usage on the actor device for a predetermined time period of prior usage. The graphical representation may comprise a plurality of stripes, each stripe representing a particular application or application type.

Abstract: A design engine includes a geometry module and a metric module that interoperate to generate optimal design options. The geometry module initially generates a spectrum of design options for a structure based on project constraints and design criteria set forth by potential occupants of the structure. The metric module then analyzes each design option and generates, for any given design option, a set of metrics that indicates how well the given design option meets the design criteria. The geometry module then generates additional design options in an evolutionary manner to improve the metrics generated for subsequent design options.

Abstract: A method and system provide the ability to design a surface. An existing triangular surface mesh representative of an existing surface is obtained. A modification to the mesh in compliance with design constraints is received. A volume level set or a volume minimization set, for the modified mesh, is obtained in Euclidean space. A volume subgradient set based on the volume level set, is obtained. A scalar is determined and used to scale heights between vertices of a triangle. A projection is computed and may be scaled. The projection may then be removed from the triangle's vertices. The removing changes the triangular surface mesh into a converged triangular surface mesh that minimizes an objective function. The objective function computes an absolute earthwork volume and/or an absolute value of a net volume representing the difference between a fill and cut of earthwork material.

Abstract: A method, system, and apparatus create a 3D CAD model. Scan data from two or more structured scans of a real-world scene are acquired and each scan processed independently by segmenting the scan data into multiple segments, filtering the scan data, and fitting an initial model that is used as a model candidate. Model candidates are clustered into groups and a refined model is fit onto the model candidates in the same group. A grid of cells representing points is mapped over the refined model. Each of the grid cells is labeled by processing each scan independently, labeling each cell located within the refined model as occupied, utilizing back projection to label remaining cells as occluded or empty. The labels from multiple scans are then combined. Based on the labeling, model details are extracted to further define and complete the refined model.
