Character recognition system and method based on combination of neural network and attention mechanism

The invention claims to protect a character recognition system and method based on the combination of a neural network and an attention mechanism, the system comprising: a convolution neural network feature extraction module, which is used for spatial feature of character image; The spatial features extracted by the convolution neural network are input to the bi-directional long-short memory network module, and the bi-directional long-short memory network can extract the sequence features of characters. The extracted feature vectors are semantically encoded, and then the attention weights of feature vectors are assigned through the attention mechanism, so that the attention is focused on the feature vectors with higher weights. In the decoding part of the model, the features extracted fromattention and the prediction information of the previous time are used as the inputs of the nested long-short memory network. The purpose of using the long-short memory network is to keep the temporal characteristics of the eigenvectors and make the attention points of the model constantly change with time. In the decoding part, the features extracted from attention and the prediction informationof the previous time are used as the inputs of the nested long-short memory network. The invention can more accurately detect the text area in the natural scene, and has good detection effect on thesmall target text and the text with small tilt angle.

Text classification method of Chinese web page based on steam clustering

InactiveCN101727500AWide coverageWord segmentation method is simple and easySpecial data processing applicationsFeature vectorThe Internet
The invention relates to a text classification method of a Chinese web page based on steam clustering, belonging to the technical field of internetwork data mining. The text classification method comprises the following steps of: acquiring a web page in real time; removing unprocessed labels in the format of the web page, and analyzing the characteristic information of texts of the web page; segmenting the content of the texts, using as ngram participles, and forming a plurality of word strings; computing the weight value of each word string; extracting the word string with a high weight value, and using the word string with the high weight value and the corresponding weight value thereof as characteristic vectors; computing the similarity of the characteristic vectors and characteristic information and a known class; computing obtained total similarity, and classifying the texts to the know class or establishing a new class; judging whether the know class is divided into two subclasses or not according to the number of characteristic items of the known class; and storing processed text records and the information of the known class. The text classification method sufficiently excavates the effective information of web page texts aiming at the characteristics of the web page texts and is incremental, fast, effective and more practical.

Bag, bag pack, and bag dispensing system

ActiveUS20050087542A1Resists tearingCarry substantial amount of weightBagsSacksThermoplasticCarrying capacity
A tabless, self-opening T-shirt-styled thermoplastic bag is provided having a handle, stress relief notch, and mounting tab structure for providing a wide-opening bag mouth and a bag having high weight carrying capacity. Handles have a narrow upper portion, a wide middle portion and a narrow lower portion. Handle mounting apertures are provided in the wide middle portion, which projects inwardly above the mouth of the bag. The handle mounting apertures are formed by a blade having an elongate section that is bent to form an obtuse angle. The handle mounting aperture has a sufficient width for accommodating arms of a dispensing rack and a height about three times as great as the width. The bag has a central mounting tab extending above the mouth of the bag and between the handles. A stress relief notch having a reasonably tight radius of curvature is provided between each handle and the mounting tab. The mounting tab has a mounting aperture formed by two blades meeting at a sharp corner, the corner having essentially no radius of curvature. A severable region is provided between the corner and an outer edge of the mounting tab, which can tear as the bag is removed from a mounting hook on a dispensing rack. Multiple bags are aligned and bonded together to provide a unitary pack, where pulling one bag off a dispensing rack pulls an adjacent bag open.

Commodity recommending method of e-commerce website based on keywords

Disclosed is a commodity recommending method of an e-commerce website based on keywords. The method includes entering the e-commerce website through search links when a user searches commodities through a search engine, collecting the keywords and related commodity information carried by the search engine by the e-commerce website through scripts, obtaining an association list of the keywords according to association degree among the keywords, and obtaining an index database through an index relationship between the keywords and related commodities; when a new user visits the e-commerce website through the search engine, analyzing the user referrer to obtain the keywords, obtaining corresponding commodity list through the search of the association list of the keywords and the index database, and recommending N pieces of commodities with the highest weight. The commodity recommending method of the e-commerce website based on the keywords solves the problem of the lack of data of new users through collecting the keywords carried by the search engine of new users, combines the index relationship between the key words and commodities obtained from historical data training, calculates commodity weight according to information such as commodity frequency, and recommends commodities to new users without any behavior records.

Navigation positioning correction method and device, and positioning navigation system

The invention provides a navigation positioning correction method and a navigation positioning correction device based on a global positioning system, and a positioning navigation system. The method comprises the following steps of: receiving a current positioning point acquired by the global positioning system; selecting a road with the highest weight factor as a matching road of the current positioning point, and determining that a parameter of the weight factor comprises an accordance degree of a current travelling direction and a direction of the road, and an approaching degree of the current positioning point and the road; and taking a projection point of the current positioning point to the matching road as a map matching point of the current positioning point. By the invention, an accurate matching point on a map is obtained by calculating the accordance degree of the current travelling direction and the direction of the road, and the approaching degree with each road, and projecting to the road with the highest matching degree. Compared with the conventional method for matching based on a distance only, the invention has higher precision and adaptability, and can solve thepositioning problem under complex situations, such as vehicle turning, multi-intersection selecting, main and auxiliary road selecting and the like.
