Abstract: A service data processing method is provided, including: obtaining a target function and a constraint condition, where the constraint condition includes a constraint relationship between a plurality of variables, and the target function includes at least one variable of the plurality of variables; selecting an initial variable from the plurality of variables for a base variable group; sorting optimized values of variables in a non-base variable group to obtain a maximum heap structure, where each node in the maximum heap structure stores an identifier of a variable and an optimized value corresponding to the variable; updating the non-base variable group and the base variable group based on a first target variable; and obtaining a solving target of a service problem based on a variable in an updated base variable group and the constraint condition.

Abstract: Provided are a method and apparatus for translating words in a picture, an electronic device, and a storage medium. The method includes: recognizing words embedded in a target picture to obtain at least one text line, each of which corresponds to one line of words; perform paragraph combination on the at least one text line to obtain at least one text paragraph; translating the at least one text paragraph into at least one target text paragraph in a specified language; and replacing the words in the target picture with the at least one target text paragraph.

Abstract: A method for automatically picking up seismic velocity based on depth learning is disclosed. The method includes obtaining a seismic data and labels, and inputting the seismic data and the labels into a pre-trained depth learning model to obtain a velocity pick-up result. A structure of the depth learning model includes a residual network composed of three residual blocks. And after the residual network, a long-short term memory network and a full connection layer are further added. Each of the residual blocks is composed of three convolutional layers. An activation function between each residual block and each convolutional layer of the residual block is a Relu function. An activation function between the long-short term memory network and the full connection layer is a Relu function. The method for automatically picking up seismic velocity based on depth learning provided by the disclosure effectively improves the efficiency of seismic velocity pick-up.

Abstract: A dimmer switch configured to be controlled by a remote controller is provided. The dimmer switch comprises a supporting portion for supporting the remote controller, and the remote controller is selectively matched in the supporting portion. A first surface of the supporting portion that is configured to be in contact with the remote controller is disposed with a first electric connection member configured to be in data communication with the remote controller, and a second surface of the remote controller that is configured to be in contact with the first surface of the dimmer switch is disposed with a second electric connection member configured to be in data communication with the dimmer switch. When the remote controller is matched with the supporting portion of the dimmer switch, the first electric connection member of the dimmer switch is in contact with the second electric connection member of the remote controller.

Abstract: A beam splitter plate configured to dispose obliquely in a transmission path of an imaging beam of a camera and comprising a transmissive plate, and a beam splitter film supported on the transmissive plate and parallel to the transmissive plate, wherein the beam splitter film is configured to reflect visible light and transmit near-infrared light, or the beam splitter film is configured to reflect the near-infrared light and transmit the visible light, wherein a thickness of the transmissive plate satisfies that transmission path lengths of the visible light and the near-infrared light in the imaging beam in the transmissive plate are both less than a projection length of the beam splitter film on an optical axis of the imaging beam.

Abstract: A photographic apparatus has an anti jitter optical lens for jitter-reduction. The anti jitter optical lens is disposed between an optical lens group and a photosensitive device of the photographic apparatus, and has no focusing power. The photographic apparatus includes an adjustment component connecting the anti jitter optical lens to an inner wall of a lens barrel of the photographic apparatus, and a control component for actuating the adjustment component to adjust an orientation of the anti jitter optical lens or a position of the anti jitter optical lens along an optical axis to compensate for jitter of the photographic apparatus.
