  • Publication number: 20240362732
    Abstract: Two sets of data, each containing property listings, are obtained from two discrete merchant platforms. Each property listing in a set of data of a first merchant is sequentially paired with each of the property listings in a set of data of a second merchant. For each pair, each image of the property listing of the first merchant is compared to each image of the property listing of the second merchant, and images of statistically sufficient similarity are identified. The similarity of images, and in particular, of similar images likely to be rooms of the property, are considered in a determination of whether the product listings of the first and second merchant are for the same cross-listed product.

  • Publication number: 20240160961
    Abstract: Disclosed in the present invention is a differentiable method for mining constant rules. On the basis of defining constant operators and path operators according to a knowledge graph, a fusion attention mechanism is used to evaluate relations passed by rules by using attention values. Meanwhile, attentions are calculated by aggregating surrounding attributes and the corresponding attribute values for tail node of each hop respectively. Attentions of the attributes are used to enhance selection of relations in the rules to achieve link prediction. According to generated model parameters, high quality symbolic rules are output by parameter analysis and statistics. This method is particularly suitable for application scenarios with complex reasoning requirements that require high prediction accuracy, provide interpretations for predictions, and need to precipitate reasoning rules.

  • Patent number: 11907368
    Abstract: Anomalous activities on a computer network are detected from audit or sign-in activity information of a target entity as recorded in an audit or sign-in log. A baseline graph of the target entity is generated using information on activities of the target entity during a collection period. A predict graph of the target entity is generated with information on activities of the target entity during another collection period, which follows and is shorter than the earlier collection period. A residual graph that indicates nodes or edges that are in the predict graph but not in the baseline graph is generated. The residual graph is scored and the score is compared to a threshold to determine whether the target entity has performed an anomalous activity.

  • Patent number: 10677817
    Abstract: A method for oscilloscope 3D mapping in scan mode. The input signal is acquired using a real-time sampling rate which is Dr times higher, thus more sampling points, i.e. Dr acquired data can be obtained during the time interval between two consecutive horizontal pixels. The Dr acquired data are mapped into a same column of the screen to implement fluorescent waveform display. In addition, to realize the scanning display, a flag X is introduced into the three-dimensional database, when the screen refresh signal arrives, the first Ds acquired data are read out from the unread acquired data in FIFO memory. The three-dimensional database is updated from the flag X, which make the leftmost waveform always be the oldest waveform, the rightmost waveform always be the newest waveform. Thus the 3D mapping is realized in scan mode, letting the DSO have a fluorescent waveform display at slow time-base.

  • Patent number: 10621548
    Abstract: This disclosure includes systems for regression-tree-modified feature vector machine learning models for utilization prediction in time-expiring inventory. An online computing system receives a feature vector for a listing and inputs the feature vector and modified feature vectors into a demand function to generate demand estimates. The system inputs the demand estimates into a likelihood model to generate a set of request likelihoods, each request likelihood representing a likelihood that the time-expiring inventory will receive a transaction request at each of a set of test price and test times to expiration. The system further trains a regression tree model based on a set of training data comprising each of the request likelihoods from the set and the test price and test time period to expiration used to generate the demand estimate that was used to generate the request likelihood.
