Abstract: Methods and systems for generating synthetic data. In some aspects, the system receives a first set of candidate behaviors, each of which comprises plain text. The system processes the first set of candidate behaviors using a first language processing model to generate a set of representations in an embedding space. For each representation in the set of representations, the system processes the representation using a second language processing model to generate a first sequence of behavioral tokens representative of a timeline of user activities. Using the set of representations and first sequence of behavior tokens, the system updates the second language processing model. Using the updated second language processing model, the system processes a second set of candidate behaviors to generate a second sequence of behavior tokens.

Abstract: In some implementations, an expert system may receive, from a user device, a data structure representing a project associated with a technical request. The expert system may map the data structure to a graph representation of a user space to determine a set of users. The expert system may determine a set of statuses, corresponding to the set of users, associated with availability of the set of users. The expert system may transmit, to the user device, instructions for a user interface including visual indicators for the set of users and the set of statuses. The expert system may receive, from the user device, an indication of a selected user from the set of users and may transmit a message addressed to the selected user.

Abstract: In-situ fluorimeters and methods and systems for collecting and analyzing sensor data to predict water source contamination are provided. In one embodiment, a method is provided that includes receiving sensor data regarding a water source. Changepoints may then be calculated within the sensor data and the sensor data may be split into intervals at the changepoints. A machine learning model may then be used to classify the intervals and a predicted contamination event for the water source may be identified based on the classified intervals. In another embodiment, an in-situ fluorimeter is provided. The in-situ fluorimeter comprises one or more UV LEDs centered around a pre-set excitation wavelength (e.g., a TLF excitation wavelength), a bandpass filter, a lens, a photodiode system, a machine learning platform; and an alarm triggered by contamination events, wherein the alarm is calibrated through the machine learning system.

Abstract: An aerodynamic wing assembly includes a stanchion, a wing and an actuator feature. The stanchion includes an internal passageway. The wing is supported on the stanchion and is displaceable between a home position and a deployed position. The actuator feature functions to displace the wing between the home position and the deployed position while being accommodated in the internal passageway.
