This disclosure relates to a method and an apparatus for training a text classification model. The method may include determining a semantic representation of the training sample using the text classification model and determining a predicted classification result of the training sample based on the semantic representation. The method may further include generating an adversarial sample corresponding to the training sample based on the training sample and perturbation information and determining a semantic representation of the adversarial sample corresponding to the training sample using the text classification model. The method may further include determining a classification loss of the text classification model based on the predicted classification result, determining a contrastive loss of the text classification model based on the semantic representation and the semantic representation of the adversarial sample, and training the text classification model based on the classification loss and the contrastive loss.

A diesel-storage independent microgrid and a virtual dynamic synchronous control method and system are described. An adaptive dynamic synchronous torque and pre-synchronous compensation phase angles are introduced into a energy storage converter control system to realize output voltage and power synchronization before and after parallel connection of the system. By compensating the pre-synchronous phase angles, the phase angles of a diesel generator and an energy storage converter are kept consistent before parallel connection, which reduces current impact during the parallel process. By introducing the adaptive dynamic synchronous torque, after the parallel connection of the system, the virtual torque of the energy storage converter can be adaptively and dynamically adjusted according to the current accelerations of the diesel generator and the energy storage converter under the condition that the inertial parameter of a diesel engine is black-boxed.

The present invention discloses an LED display screen layout method, including an LED display screen, wherein the LED display screen is formed by splicing a plurality of LED modules; each LED module includes four tricolored LED lamps; the four tricolored LED lamps form a square; and the four tricolored LED lamps are arranged in directions formed by sequentially rotating one of the tricolored LED lamps by 90 degrees. With such layout design, when the LED display screen is rotated, no blue line appears at neighboring borders of the LED modules, thus not influencing the display effect of the display screen.

A trampoline has a side frame supported by support legs, multiple fiberglass guardrail poles joined to the side frame or the support legs, and a guardrail netting held open by the guardrail poles. Each guardrail pole includes two fiberglass rods joined together by a connector that includes two nested securing tubes, where two respective ends of the two fiberglass rods are inserted in the internal securing tube. The external securing tube is secured outside of the internal securing tube. The guardrail netting has multiple securing fabric sleeves stitched to its top end. Each sleeve has a first part with a sealed top and a width matching that of a wider top section of the fiberglass guardrail pole, and a second part connected to the first part with a width matching that of the fiberglass guardrail pole, where the second part has a gap in the middle.

A method and an apparatus for correcting a tilt of a subject occurred in photographing, as well as a mobile terminal and a computer storage medium are provided. In some embodiments, the method includes: after it is detected by a mobile terminal that the subject enters a viewfinder interface, identifying a boundary of a profile of the subject to obtain the profile of the subject; analyzing the profile of the subject to determine whether the subject is tilted; and performing a process for straightening and photographing on the subject to obtain a picture in which the subject is straightened if the subject is determined to be tilted.

A quantum dot lighting device includes a quantum-dot-lighting layer and two main structural layers being arranged at two sides of the quantum-dot-lighting layer along a vertical direction. The quantum-dot-lighting layer includes a red lighting unit, a green lighting unit, and a red lighting unit. The red lighting unit includes red quantum dots, the green lighting unit includes green quantum dots, and the blue lighting unit includes blue quantum dots. A number of the blue quantum dots is larger than the number of the green quantum dots, and the number of the green quantum dots is larger than the number of the red quantum dots. With the configuration, the material of the quantum dots may be reduced, and the pureness of the white light beams may be enhanced.

Disclosed herein is a multifunctional crib, which includes a bedstead, a bedplate member and a bouncing member. The bedstead includes an upper enclosure frame, a lower enclosure frame and at least three three-way connectors that connect the upper and lower enclosure frames. The bedplate member is removable and can be installed on the bedstead. The bouncing member is removable and can be installed in a closed area of the lower enclosure frame, which is below the bedplate member. There is bouncing space between the bouncing member and the ground. An exterior protective net is installed outside the periphery of the bedstead. Such a crib can serve as not only a crib, but also a trampoline and game pool, to avoid a waste of resources.
