Title: Method and apparatus for joint training logistic regression model
Inventor: CUI JINMING
IPC: G06F17/18
Filed: 2023-03-31
Abstract: Some embodiments of this specification provide methods for jointly training a logistic regression model. The training includes three types of training data: a sample characteristic, a sample label, and a model parameter, each of which is split into fragments that are distributed between two parties. The method is performed by either first party of the two parties, and includes: performing masking on three first-party fragments corresponding to the three types of training data by respectively using first fragments of three random numbers in a first fragment of a random array to obtain three first mask fragments, and sending the three first mask fragments to a second party, where the first fragment of the random array is a fragment, sent by a third party to the first party, of two-party fragments that are obtained by splitting values in the random array generated by the third party; constructing three pieces of mask data corresponding to the three types of training data by using the three first mask fragments and three second mask fragments received from the second party; and performing a first calculation based on the three pieces of mask data and the first fragment of the random array to obtain a first gradient fragment for updating the first-party fragment of the model parameter.

Abstract: A system (100) includes a generator (102). Three AC feeders (104a, 104b, 104c) are connected for feeding AC output from the generator (102). A rectifier (106) is electrically connected to the three AC feeders (104a, 104b, 104c) and to a load via a first DC feeder (108p) and a second DC feeder (108n). A first resistor (110) connects between the first DC feeder (108p) and ground (112). A second resistor (116) connects between the second DC feeder (108n) and ground (112). At least one of a first current sensor (114) is operatively connected to detect current in the first DC feeder (108p) and/or a second current sensor (118) is operatively connected to detect current in the second DC feeder (108n). A controller (124) is configured to monitor for changes in common mode current based on the input from the at least one current sensor (114, 115, 118), and to determine presence of a fault if change in the common mode current exceeds a predetermined threshold.

Title: Schaltkreis zur Einstellung des Widerstandswertes eines Abschlusswiderstandes von Leitverbindungen in Halbleiterstrukturen
Inventor: ANANTHA NARASIPUR GUNDAPPA
IPC: H01L21/822
Filed: 1978-12-16
Abstract: In Leitverbindungen von Halbleiterstrukturen ist ein durch eine Bezugsspannung änderbarer Abschlußwiderstand vorgesehen. Durch diesen kann wahlweise eine Anpassung an den Übertragungswiderstand einer Leitverbindung hergestellt werden, die von einer Schaltkarte über ein Modul zu einem Chip gebildet wird. Verschiedene Leitungskapazitäten einer solchen Leitverbindung ergeben verschiedene Impedanzwerte. Der Abschlußwiderstand wird durch einen sogenannten Pinch-Widerstand (60) gebildet. Von einer Leitverbindung übertragene Signale werden einem Anschluß des Pinch-Widerstandes und einem ersten Steuereingang eines Differenzverstärkers (Transistoren T1, T2) zugeführt, dessen zweiter Steuereingang mit einer gewählten Bezugsspannung verbunden ist. Der Ausgang des Differenzverstärkers ist über einen Zwischenverstärker (Transistor T5) mit einer oder mehreren Steuerelektroden von einem oder mehreren Pinch-Widerständen verbunden, von denen jeder den Abschlußwiderstand einer Leitverbindung bildet.

Abstract: A modular framed structure is constructed by using uniform, rigid Y joints (10) which have branches (12a,12b,12c) forming angles of 120°, 120° and 108° in space. The Y joints (10) are either directly welded to other Y joints or indirectly connected to other Y joints through couplings or bolts. These framed structures are interconnected to form structural supports over which roofing material will be spanned with or without prestress. Where three hexagonal panels meet, stiffening effect of the structural frame will further strengthen the structural resistance.

Abstract: A domestic appliance comprises a programming device for receiving on-time information and for updating, by way of repetitious signals, the ontime yet to be completed. Furthermore, these repetitious signals continuously activate an activation signal which, however, is independently terminated if the repetitious signals do not appear. When the activation signal is present, first and second switching components are activated, so that a discharge tube can emit ultraviolet radiation. Furthermore, there is provided a detection element which detects whether the first and second switching components are indeed deactivated outside the on-time. If one of the two switching components remains active also outside the on-time, the detection element supplies a signal to prevent the starting of a next on-time.
