Title: Systems and methods for training complex machine learning models
Inventor: AGNIESZKA M WERPACHOWSKA
IPC: G06N3/08
Filed: 2021-02-03
Abstract: A computer-implemented method for training one or more machine learning models involves dynamically scaling a learning rate to avoid overfitting and brittleness. The training process comprises an initialisation step where one or more learning sets are created from batches of a training dataset, each learning set including a gradient part and a smaller holdout part. An update step of the training process involves obtaining a machine learning model with a current learning rate and parameter set. A learning set is obtained and a relative difference between gradient losses of its gradient part and holdout part is calculated. The learning rate for the machine learning model is scaled based on this relative difference. The parameter set of the machine learning model is updated based on a gradient of a predetermined loss function for the gradient part, the current parameter set, and the scaled learning rate.

Filed: 2022-12-02
Abstract: Method of navigating an autonomous driverless vehicle, by sensing the environment 800 surrounding the ego vehicle 508 and populating an occupancy map (fig 6c), generating a provisional reference path 804 to a target destination location 808, and determining an actual travel trajectory to intermediate interval points 802, the intermediate points 802 being proximal to points 806 along the reference path 804.

Multiple potential travel paths, each comprising series of unit-distance steps, may be generated and one selected based on e.g. collision risk, comfort cost, or degree of difference in heading. The position of the vehicle 508 and other obstructing obstacle objects, the reference path 804, and the actual travel trajectory may be converted to the coordinates of the occupancy map (fig 6c) for planning, and returned back to the physical coordinates for navigating the vehicle 508. Third order B-spline basis may be applied to a differentiable occupancy map evaluation to avoid jumps in object representation.

IPC: F25B49/02
Filed: 2022-06-14
Abstract: A vapour compression cycle system (14, Fig. 1) is controlled so that a compartment (11, Fig. 1) is cooled or heated and a temperature in the compartment is monitored. A temperature maintenance mode TM uses hysteresis to maintain the temperature between upper and lower temperature bounds that are offset from a required set point temperature. A cooling or heating power demand value Q is chosen from a plurality of power demand values according to evaporating temperature or pressure, condensing temperature or pressure, and efficiency. The compartment may be cooled in a temperature pulldown mode PD with a fixed or maximum cooling power demand value Qmax, or heated in a temperature pullup mode with a fixed or maximum heating power demand value. A lookup table may be used to select the most efficient power demand value. A minimum power demand value (Qmin, Fig. 7B) may be dynamically recalculated according to the difference between the set point temperature and the monitored temperature. Methods of controlling the system by determining a power demand value from monitored and required temperatures, and determining a compressor capacity from a look up table are also disclosed.
