Abstract: The system obtains a floor plan associated with a construction site, and a three-dimensional computer model of the construction site, a trajectory through the construction site, and a recording of the construction site. The system establishes a correspondence between the trajectory and the floor plan. Based on the correspondence between the trajectory and the floor plan, the system creates a virtual camera associated with the three-dimensional computer model and a virtual trajectory, where the virtual trajectory influences virtual objects visible to the virtual camera, and the virtual objects visible to the virtual camera match objects visible to a camera making the recording. The system determines a transformation of the camera between an initial image and a subsequent image in the recording, and applies the transformation to the virtual camera to obtain a virtual trajectory of the virtual camera associated with the three-dimensional computer model.

Abstract: The system obtains a hierarchy representing a construction site, and multiple queries associated with a node in the hierarchy, where a query among the multiple queries requests an indication of a stage of construction associated with an object at the construction site represented by the node, and where the query among the multiple queries requests an answer from a binary set. The system obtains a recording of the object at the construction site and presents the recording and the multiple queries to a user. The system receives the answer from the binary set from the user, and creates an artificial intelligence training dataset based on the answer associated with the binary set and the recording of the object.

Abstract: The system obtains a hierarchy representing a construction site, where the hierarchy includes a parent node and a child node, and obtains a first computer model of a first construction site including a first multiplicity of virtual objects. Based on the hierarchy representing the construction site, and the first computer model of the first construction site, the system creates a first map between the hierarchy representing the construction site and the first computer model of the first construction site. The system trains an artificial intelligence based on the first map, and then provides to the artificial intelligence a second computer model of a second construction site. The system receives from the artificial intelligence a second map between the hierarchy representing the construction site and the second computer model.

Abstract: The system obtains a first recording of a construction site captured at a first time, and a first virtual trajectory of a first virtual camera, and creates a first data structure representing the first recording. The system obtains a second recording of the construction site captured at a second time, and creates a second data structure representing the second recording. The system establishes a correspondence between the first and second data structures by creating a map between a second image in the second recording and a first image in the first recording by efficiently searching the first data structure for the first image similar to the second image. The system obtains a first location of the first virtual camera corresponding to the first image and, based on the map between the first and second image, determines a second location of a second virtual camera corresponding to the second image.

Abstract: Described are techniques for disintegrating an entity into smaller entities. A graph (“first graph”) for the entity of records to be disintegrated is constructed, where each vertex of the first graph represents a record in the entity of records to be disintegrated. The edges in the first graph connecting records in the entity of records represent matching links between the records, where each edge is associated with a weight corresponding to a similarity score. Furthermore, two or more additional graphs representing two or more sub-entities of the entity of records to be disintegrated are constructed. Such graphs are constructed based on selecting edges with a maximum weight out of the edges connected between each pair of records in the first graph or based on the number of connections each record has with other records in the first graph exceeding a threshold value.

Abstract: Techniques are described herein for detecting an invalid (e.g., spoof) email before it is received by an intended recipient. In some embodiments, the techniques may involve, upon receiving an electronic communication directed to an intended recipient, determining, based on information included in the electronic communication, a claimed source entity, and determining a domain associated with the email communication. The techniques may further involve determining an owner entity associated with the domain and then determining that the electronic communication is valid based on a comparison between the owner entity and the claimed source entity. Upon determining that the electronic communication is not valid, the techniques may further comprise performing one or more mitigation techniques.

Abstract: Technologies for fiber array unit (FAU) lid designs are disclosed. In one embodiment, channels in the lid allow for suction to be applied to fibers that the lid covers, pulling the fibers into place in a V-groove. The suction can hold the fibers in place as the fiber array unit is mated with a photonic integrated circuit (PIC) die. Additionally or alternatively, channels can be on pitch, allowing for pulling the FAU towards a PIC die as well as sensing the position and alignment of the FAU to the PIC die. In another embodiment, a warpage amount of a PIC die is characterized, and a FAU lid with a similar warpage is fabricated, allowing for the FAU to position fibers correctly relative to waveguides in the PIC die. In another embodiment, a FAU has an extended lid, which can provide fiber protection as well as position and parallelism tolerance control.

Abstract: Techniques for an email-security system to screen emails, extract information from the emails, analyze the information, assign probability scores to the emails, and classify the emails as likely fraudulent or not. The system may analyze emails for users and identify fraudulent emails by analyzing the contents of the emails. The system may evaluate the contents of the emails to determine probability score(s) which may further determine an overall probability score. The system may then classify the email as fraudulent, or not, and may perform actions including blocking the email, allowing the email, flagging the email, etc. In some instances, the screened emails may include legitimate brand domain addresses, names, images, URL(s), and the like. However, the screened emails may contain a reply-to domain address that matches a free email service provider domain. In such instances, the email-security system may assign a probability score indicative that the screened email is fraudulent.

Abstract: Techniques for an email-security system to detect multi-stage email scam attacks, and engage an attacker to obtain additional information. The system may analyze emails for users and identify scam emails by analyzing metadata of the emails. The system may then classify the scam emails into particular classes from among a group of scam-email classes. The system may then engage the attacker that sent the scam email. In some instances, the scam emails may be multi-stage attacks, and the system may automatically engage the attacker to move to the next stage of the scam attack. For instance, the system may send a lure email that is responsive to the particular scam class to prompt or provoke the attacker to send more sensitive information, such as a phone number, a bank account, etc. The system may then harvest this sensitive information of the attacker, and use that information for various remedial actions.
