摘要： An association connection is established between a first Bluetooth Low Energy (BLE) device operating in central mode and attached to an asset to track, and a second BLE device operating in peripheral mode and associated with a physical location within the asset management environment. An association connection is established between the second BLE device and a third BLE device operating in central mode and coupled to one or more computer processors, and the association information stored in the second BLE device to the third BLE via one or more broadcasting frames is periodically transmitted. Based on current association information between the first BLE device and the second BLE device, an identity of the asset to which the first BLE device is attached, and the physical location of the second BLE device within the asset management environment is identified.

摘要： The present invention relates to data compression and decompression, and particularly relates to a method and an apparatus for compressing and decompressing signal data. In an embodiment of the present invention, there is disclosed a method for compressing signal data, comprising: obtaining signal data; determining block lengths of a plurality of data blocks into which the signal data are divided, and determining exponents of the data blocks; forming a mantissa sequence of the data block by using the exponent of the data block to compress signal data contained in the data block; and forming a compressed data block by using the block length, the exponent and the mantissa sequence of the data block. By constructing a variable-length data block adapted to dynamic characteristics of signal data, the method for compressing signal data of the present invention increases the compression ratio of signal data.

摘要： Aspects of the invention include methods and systems that include obtaining a source domain dataset. The source domain dataset includes corresponding labels, and the source domain dataset and the corresponding labels are associated with training a source domain machine learning model. A method includes obtaining a target domain dataset without corresponding labels and a feature vector that identifies features in the source domain dataset and the target domain dataset. The method also includes obtaining a set of loss terms from known machine learning models that implement a domain adversarial neural network (DANN) architecture. The DANN architecture includes feed-forward propagation and backpropagation. A target domain machine learning model is obtained based on the source domain dataset, the target domain dataset, the feature vector, and the set of loss terms and without labels for the target domain dataset to perform training.

摘要： A method, system, and computer program product for hyper-parameter determination. In a method, a network architecture of a learning model may be determined, and the learning model may be configured for performing a computing task based on machine learning. A metric value record associated with a group of hyper-parameters may be obtained during hyper-parameter determination for the learning model. An estimation of a metric value may be obtained based on the network architecture, and the metric value record and an association relationship representing an association between network architectures and metric values for the network architectures.
