Abstract: Embodiments of the present disclosure propose an Erasing-based Lossless Floating-point compression method, i.e., Elf. The main idea of Elf is to erase the last few bits (i.e., set them to zero) of floating-point values, so the XORed values are supposed to contain many trailing zeros, where the erased bits are determined based on the decimal place count and the digits on the exponent bits.

Abstract: Provided are a configuration method and apparatus for dual-mode converged communication, and a dual-mode converged communication system. The method includes: determining a first operating frequency band of power line communication (PLC) and a second operating frequency band of radio frequency (RF) communication; and configuring a second frequency band number of the second operating frequency band based on a first frequency band number of the first operating frequency band, such that a high-order harmonic frequency of a first operating clock of the PLC and a high-order harmonic frequency of a second operating clock of the RF communication do not overlap with the first operating frequency band or the second operating frequency band. This can reduce an impact of multiplicative noise generated by harmonic superposition and an impact of noise generated by a CPU during operation on performance of a dual-mode converged communication unit, improving transmission efficiency of dual-mode converged communication.

Abstract: Systems and methods are provided for implementing automatic prompt optimization using textual gradients. In various embodiments, a feedback prompt, input into a large language model (“LLM”), is used to generate textual gradients that criticize a current prompt. The feedback prompt includes the current prompt and predictions that are incorrect compared with corresponding labels associated with minibatch data processed by the LLM using the current prompt. The textual gradients and current prompt are used in an editing prompt to the LLM to obtain a set of optimized prompts, which may be expanded using a paraphrasing prompt that is input into the LLM to generate a set of paraphrased prompts. A selection algorithm is used to select one or more optimized prompts from the set of optimized prompts and/or the set of paraphrased prompts, and the process is repeated with the selected one or more optimized prompts replacing the current prompt.

The locking member and the operating member are rotatable to one another. Rotation of the nut loosening/tightening member around a first axis is obstructed by the locking member. When the operating member is in the operating position, the first matching portion is disengaged from the second matching portion, and rotation of the nut loosening/tightening member around the first axis tightens or loosens the nut.
