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.

Abstract: An image data processing method, a system and an electronic device are provided. The method includes: recording to-be-processed database data as a target image set; performing sharpness calculation on target images in the target image set by a weighted gradient algorithm, and removing, if sharpness of at least one target image is smaller than a threshold, the at least one target image from the target image set; performing sharpness enhancement processing on remaining target images in the target image set; extracting feature points in the target images in the target image set and the contrast image, one by one or at intervals; and comparing and judging similarity between the target images and the contrast image by a similarity algorithm, and inputting similar target images into classified storage spaces.

Abstract: A two-dimensional spectrum recording apparatus has a source of collimated laser light impinging on a sample on a plate. The light passing through the sample forms an object wave and the light not passing through the sample forming a reference wave, which interfere with each other to form a holographic image at the plate. A beam splitter receives the collimated laser light from the sample and forms separate first and second light beams. A linear polarizer receives the first beam and passes it to a polarization camera having a Full Stokes mask. The camera records the light that passes through the Stokes mask. A slit aperture receives the second beam and transforms it into a slit of light that is applied to a diffraction grating. A diode array receives the second beam from the diffraction grating and forms a light spectrum that is recorded.

Abstract: The present disclosure provides a group training action correction system and method combining face and gesture recognition, wherein the system includes an individual action correction moment determination module, which is configured to determine a nearest individual action correction moment after a current training progress on a preset training progress axis; and an individual action correction module, which is configured to correct and prompt individually action for the action correction object based on a standard gesture, an action to be corrected, and a personnel identity when entering the individual correction moment.
