  • Patent number: 11244156
    Abstract: Techniques for improved text normalization are provided. Signatures are generated for a first word and a second word using a locality-sensitive hashing technique. A graph is constructed based on the first and second signatures, by creating a first node in the graph for the first word, creating a second node in the graph for the second word, and creating an edge in the graph connecting the first and second nodes upon determining that the first and second signatures match. A mapping from the first word to the second word is then generated based on the graph.

  • Patent number: 11243820
    Abstract: The subject technology performs a locking operation on a first set of keys by a first statement of a first transaction. The subject technology determines that a conflict occurred between the first statement and a second transaction. The subject technology determines that the second transaction has yet to complete after a predetermined period of time. The subject technology performs a deadlock detection process where the subject technology stores a key and value in a table indicating the first transaction and the second transaction, detects, based at least in part on a graph traversal of the table starting from the first transaction, a cycle between the first transaction and the second transaction, and determines that the first transaction is a youngest transaction in the detected cycle.

  • Patent number: 10996060
    Abstract: A device, system, and methods are described to perform machine-learning camera-based indoor mobile positioning. The indoor mobile positioning may utilize inexact computing, wherein a small decrease in accuracy is used to obtain significant computational efficiency. Hence, the positioning may be performed using a smaller memory overhead at a faster rate and with lower energy cost than previous implementations. The positioning may not involve any communication (or data transfer) with any other device or the cloud, providing privacy and security to the device. A hashing-based image matching algorithm may be used which is cheaper, both in energy and computation cost, over existing state-of-the-art matching techniques. This significant reduction allows end-to-end computation to be performed locally on the mobile device.
