Abstract: Techniques are disclosed relating to multi-phase training of machine learning models using weighted training data. In some embodiments, a computer system may train a machine learning classification model in at least two phases. During an initial training phase, the computer system may train an initial version of the classification model based on a training dataset, applying equal weight to the training samples in the training dataset. The computer system may then generate model scores for the training samples using the initial version of the classification model. Based on these model scores, the computer system may generate, for the training samples, corresponding weighting values. The computer system may then perform a subsequent training phase to generate an updated version of the classification model, where, during this subsequent training phase, at least some of the training samples are weighted using their respective weighting values.

Abstract: A heat pump system, a heat management method and a vehicle are provided. The heat pump system includes an integrated heat exchanger integrated with a superconducting liquid flow passage and a refrigerant flow passage. The refrigerant flow passage is provided inside an on-board refrigerant circulation loop and is used for cooling and/or heating to adjust the temperature within a passenger compartment of a vehicle. The superconducting liquid flow passage is in communication with a motor heat dissipating conduit, for absorbing the heat generated by an on board motor and transferring the heat to the integrated heat exchanger by means of phase change heat transfer. The heat pump system can increase the energy utilization rate for the vehicle and reduce the allowable ambient temperature of the heat pump system.

Abstract: It is provided a power generation model based on a transcritical cycle with an increasing-pressure endothermic process using CO2-based mixture working fluids for an enhanced geothermal system, including a geothermal water circulation, a mixture working fluid circulation and a cooling water circulation. A coaxial pipe-in-pipe downhole heat exchanger is provided in the mixture working fluid circulation. Innovations are reflected in that an increasing-pressure endothermic process is achieved due to making use of gravity and hence increase a heat quantity absorbed in a cycle, thereby improving power generation quantity of the cycle; and a binary mixture working fluid composed of CO2 and an organic working fluid is adopted to realize a transcritical power cycle with an increasing-pressure endothermic process and a decreasing-temperature exothermic process, thereby effectively reducing irreversibility of a heat transfer between a working fluid and a heat source and improving power cycle efficiency.
