  • Patent number: 11570005
    Abstract: The present disclosure provides systems, methods, and computer-readable storage media having functionality to prove immutability of blockchains without accessing user data. A user may submit data for storage to a data management server and the data management server may generate one or more data records corresponding to the data at a database and one or more blocks at a blockchain, each block corresponding to of the data records. Block information associated with the generated blocks may be transmitted to a remote computing device for storage at a database. Prior to storing the block information, the remote computing device may sign the data using a private key or other cryptographic technique. To validate a block, raw block information may be retrieved from the blockchain and compared to the signed block information. If the signed block information matches the raw block information, the block may be determined to be valid (e.g., unchanged).

  • Publication number: 20220092697
    Abstract: A method of predicting stock price movements. The method comprises extracting sentences from earning call transcripts related to a publicly traded stock. A neural network embedding layer encodes each extracted sentence into a sentence vector. An attention layer calculates an earning call vector that is a weighted sum of the sentence vectors. A recurrent neural network encodes a time series vector of historical prices for the stock. An attention layer assigns weights to time steps of the time series. An embedding layer encodes an industry sector vector representing categorical features of the sector to which the company belongs. A concatenated vector is calculated from the earning call representation call representation vector, the time series vector, and industry sector vector. A discriminative network predicts a direction of price movement of the stock over a future time period after a new earning call conference according to the concatenated vector.
