Abstract: A data classification system obtains a data set including first data associated with a first characteristic and second data associated with a second characteristic. In response to obtaining the data set, the system uses a classification model to generate a classification by classifying the first data into majority data and the second data into minority data. From the classification and using the classification model, the system determines a loss. The system modifies the classification model based on this loss to generate an updated classification model. The system uses the updated classification model to re-classify a subset of the first data into the minority data and a subset of the second data into the majority data.

Abstract: A method, system and computer program product for mitigating errors in measurements from a quantum system. A discriminator is trained to classify the measurement results of the quantum states of qubits as corresponding to a first quantum state (e.g., quantum state of 0) or a second quantum state (e.g., quantum state of 1). A first region of trust (corresponding to trusted measurements of a first quantum state) with a first discriminator boundary and a second region of trust (corresponding to trusted measurements of a second quantum state) with a second discriminator boundary are defined using the trained discriminator. If a shot-to-shot measurement result of a qubit state falls outside such regions of trust, the measurement result is rejected. In this manner, measurement errors from a quantum system are effectively mitigated, including measurement errors involving shot-to-shot measurement results of the quantum states read from the execution of the quantum circuits.

Abstract: The present disclosure is related to a field of payment transactions using a card that discloses a computer-implemented method and a system for restricting a transaction while using a payment card. A card processing server may receive card details, a transaction amount, a flag, and signature data of the payment card from a remote terminal upon initiating a transaction using the payment card. Further, the card processing server validates the payment card based on the card details and the signature data of the payment card and thereafter determines a value associated with the flag upon successful validation.

Based on the condition indicated by the flag, the card processing server performs one of a first action and a second action related to either processing or declining the transaction.

Abstract: Various corpora of content objects and other information sources beyond the corpora of content objects are processed to identify personally identifiable information (PII). PII that is associated with a named person is codified into a first portion of a graph-oriented data structure. Also, PII that is associated with an alias that might refer to a named person is codified into a second portion of the graph-oriented data structure. A determination is made that the alias that might refer to a named person is indeed an alias that is a coreference to the named person. Based on that determination then, since the first portion of the graph and the second portion of the graph refer to the same person, then the PII of the second portion of the graph can be deemed to be PII of the same person. PII in common and/or language processing can be used to establish coreferences.

Abstract: A method for interrogating an electronic identity card by a terminal with a claim covering an identity attribute of the holder of this card. The terminal obtains an identity token of the CNIe then selects in a HD wallet an issuer account associated to the identity attribute covered by the claim. Afterwards, it forms a transaction including as arguments the identity token and the path in the arborescence of the wallet leading to the issuer account, this transaction then being transmitted to a blockchain. Afterwards, it is verified by consensus that the terminal is habilitated to issue a claim covering an identity attribute, and that the issuing address of the transaction corresponds to the identity attribute on which the terminal is habilitated to issue a claim.
