Abstract: The invention discloses method of improving AUV wireless communications systems, including steps of: collecting the channel frequency response and receiving signal data in the electromagnetic environment where AUV works on the water surface,; constructing a multi-dimensional feature aggregation network model based on self-attention mechanism; training a multi-dimensional feature aggregation network; and preprocessing received AUV signals to obtain improved input data. The network model completed by offline training is loaded, and the input data is input into the network for channel estimation. The invention uses a self-attention mechanism in deep learning to build a multi-dimensional feature aggregation network model. The estimation performance is much higher than the traditional channel estimation method, and the space-time complexity of the network is very low, which can be applied to an AUV wireless communication system through offline training.

Abstract: A substrate includes a first dielectric layer having a first surface and a second surface. The first dielectric layer includes a plurality of first conductive vias and a plurality of second conductive vias. These two kinds of conductive vias are formed to penetrate the first dielectric layer and have different orientations for reduce warpage of the substrate.

Abstract: A system, computer program product, and method are provided for entity linking in a logical neural network (LNN). A set of features are generated for one or more entity-mention pairs in an annotated dataset. The generated set of features is evaluated against an entity linking LNN rule template having one or more logically connected rules and corresponding connective weights organized in a tree structure. An artificial neural network is leveraged along with a corresponding machine learning algorithm to learn the connective weights. The connective weights associated with the logically connected rules are selectively updated and a learned model is generated with learned thresholds and the learned weights for the logically connected rules.

Abstract: Embodiments of the present disclosure disclose a method and apparatus for recommending a video. A specific implementation of the method includes: finding a recommended video corresponding to a target video from all candidate videos based on similarities of content characteristics of the videos, the target video being a video to be played on a terminal of a user; and sending play information of the recommended video corresponding to the target video to the terminal of the user. The method finds a video similar on video content to the target video that the user desires to view based on the content characteristic of the video, and recommends the video similar on video content to the target video that the user desires to view to the user.

Abstract: An integrated circuit (IC) package substrate has a dielectric layer and a micro filled via formed substantially in the center of a hole in the dielectric layer. The IC package substrate has at least one chip bonding pad and one ball attach pad that are electrically coupled to each other by the micro filled via. The micro filled via is formed of a material called a "micro filled via material" that includes a binding material and optionally includes a number of particles (between 0%-90% by volume) dispersed in the binding material. The binding material can be any material, such as a polymer that is either conductive or nonconductive. The particles can be formed of any conductive material, such as a conductive polymer or a conductive metal (e.g. copper or gold). An electrical conductor can be originally formed simply by contact between conductive particles located adjacent to each other.
