Abstract: This document relates to evaluation of automated agents. One example includes a system having a processor and a storage medium. The storage medium can store instructions which, when executed by the processor, cause the system to perform two or more data gathering iterations, which can include distributing experimental units to a plurality of agents having different agent configurations according to a sampling strategy, populating an event log with events representing reactions of an environment to actions taken by individual agents in response to individual experimental units, and adjusting the sampling strategy for use in a subsequent data gathering iteration based at least on the events in the event log. The event log can provide a basis for subsequent evaluation of the plurality of agents with respect to one or more evaluation metrics.

Abstract: This document relates to reinforcement learning. One example includes a system having a processor and a storage medium. The storage medium can store instructions which, when executed by the processor, cause the system to identify a selected agent configuration having a corresponding selected reward function based at least on predicted performance of a plurality of alternative agent configurations for an evaluation metric. The instructions can also cause the processor to operate the agent in the selected agent configuration. The selected agent configuration can cause the agent to adapt internal parameters of the agent according to the selected reward function.

Abstract: A method is for controlling an actuation force exerted by an actuating device having a first working chamber and a second working chamber supplied with pressurized air from a source of pressurized air by a first pressure regulator and a second pressure regulator. The method includes calculating, by an optimization algorithm based on a dynamic model of the actuating device and of the first and second pressure regulators, desired values for control signals for the first and second pressure regulators to generate an actuation force equal to a desired value for the actuation force. An estimated value for the actuation force, estimated values for pressures inside the first and second working chambers and for first derivatives of the pressures, are determined by a state observer based on a measured value for the actuation force and on measured values for the pressures in the first and second working chambers.

Abstract: An automotive electronic dynamics control system for an automated motor-vehicle. The electronic dynamics control system is designed to implement two distinct Model Predictive Control (MPC)-based Trajectory Planners comprising a Longitudinal Trajectory Planner designed to compute a planned longitudinal trajectory for the automated motor-vehicle; and a Lateral Trajectory Planner designed to compute a planned lateral trajectory for the automated motor-vehicle. The electronic dynamics control system is further designed to cause the planned longitudinal trajectory to be computed before the planned lateral trajectory.

Abstract: Systems and methods for tuning hyperparameters for a machine learning model using a challenger champion model are described. A set of challenger configurations are generated based on a hyperparameter for tuning and a subset of the set of challenger configurations are scheduled for evaluation based on a loss function. A loss value derived from the loss function for the challenger configurations is compared to a loss value derived from the loss function for a champion configuration, and the champion configuration is replaced with the challenger configuration based on the comparison of the loss value derived from the loss function for the challenger configuration and the loss value derived from the loss function for the champion configuration. When the champion is replaced, a new set of challenger configurations is generated based on the new champion configuration.

Abstract: A wood coating composition comprising: an acrylic or polyurethane or alkid resin, or a combination thereof; a water-based solvent comprising water and a polyalcohol, or an organic solvent selected among ketones, esters, aromatic hydrocarbons as toluene, alone or in a combination; wherein the resin has a weight ratio set between 10% and 80% or between the 20% the 70%, respectively with an or the other type of solvent. The compositions include a UV-protection additive comprising polyphenols, in particular a mixture of tannins extracted from such a wood as a Fagaceae, Mimosaceae or Rosaceae wood, at a weight ratio set between 0.5% and 4% with respect to the weight of the composition. Essential requirement for the UV-protection additive to work in a water-based solvent-containing composition is that the pH is higher than a predetermined minimum value higher than 7.

Abstract: Business goals may be achieved using adaptive rewarding for the personalization of contents. In response to receiving user information, personalized contents for the user can be recommended using a reinforcement learning algorithm. In response to presenting the personalized content to the user, an action by the user selecting a particular content may be received. A reward value can be calculated for the action based on a reward function. The reward function can be based, at least in part, upon the action, the selected content, and/or the user. The reward function can be based upon one or more business goals, such as user engagement, monetization, and/or security. The calculated reward value can be provided to the reinforcement learning algorithm, which can be adapted based upon the reward value for future selection of personalized contents.

Abstract: A J-hook retainer includes a rigid structural component shaped with a hooked end. A soft rubber section is applied to or molded with the rigid structural component. The J-hook retainer holds a trim fabric in place over a vehicle component frame. Advantageously, the soft rubber section minimizes free play and rattling as well as assisting in avoiding sliding and detachment in case of partial contact between the J-hook retainer and vehicle component frame.
