Abstract: The present teaching relates to generating an updated model related to advertisement selection. In one example, a request is obtained for updating a model to be utilized for selecting an advertisement. A plurality of copies of the model is generated. The model is pre-selected based on a performance metric related to advertisement selection. Based on each of the plurality of copies, a candidate model is created by modifying one or more parameters of the copy of the model to create a plurality of candidate models. One of the plurality of candidate models is selected based on the performance metric. The steps of generating, creating, and selecting are repeated until a predetermined condition is met. The model is updated with the latest selected candidate model when the predetermined condition is met.

Abstract: In an example, sets of event information associated with events may be identified. The events may include intentional click events, accidental click events and/or skip events. Accidental click probabilities associated with the accidental click events and/or the skip events may be determined. Machine learning model training may be performed, using the sets of event information associated with the events and labels associated with the events, to generate a first machine learning model. The labels may include second labels associated with the intentional click events and/or third labels associated with the accidental click events and/or the skip events. The second labels may correspond to an intentional click classification. The third labels may be based upon the accidental click probabilities. Click probabilities associated with content items may be determined using the first machine learning model. A content item may be selected for presentation via a client device based upon the click probabilities.

The similarity profile may be indicative of one or more similarity scores associated with a first client device and one or more client devices. A user profile associated with the first client device may be modified, based upon the similarity profile and/or one or more user profiles associated with the one or more client devices, to generate a modified user profile. Content may be selected for presentation via the first client device based upon the modified user profile.

Abstract: A DC-DC converter including voltage and slope regulation and a method of operating the same are provided. Generally, the converter includes a voltage source to supply an output, a switching-circuit coupled to the voltage sources to control a voltage on the output, and a slope-detector coupled to the switching-circuit and the output to detect a slope of a voltage transition between a first and a second voltage. When the detected slope exceeds a predetermined maximum the slope-detector sends a digital signal to the switching-circuit to intermittently pause the voltage transition to limit the slope to less than the maximum. In one embodiment, the voltage source is a charge-pump, and the switching-circuit includes a logic-gate coupled to the slope-detector to turn the charge-pump ON when the detected slope is less than the maximum, and to turn OFF the charge-pump for a time when the slope exceeds the maximum.

Abstract: A differential-slope-limiting-switch and method are provided. Generally, the switch includes a first transistor having a first source-drain (SD) and well coupled to a first port of the switch, a gate, and a second SD, and a second transistor having a first SD and well coupled to a second port, a gate, and a second SD coupled to the second SD of the first transistor. A selector-circuit couples the gate of the first transistor to a first current-source when a signal to close the switch is received, and to the first port when it is not received. A second selector-circuit couples the gate of the second transistor to a second current-source when the signal is received, or to the second port. First and second feedback-capacitors couple each gate to the port on opposite sides of the switch and with the current-sources limit a slope of voltage transitions across the closed switch.

Abstract: Method, systems, and computer-readable for selectively sharing media among two or more client devices. Initially, media (e.g., image(s), video, audio, text, etc.) can be rendered via a first client device. Portions of the media rendered on a first client device can be selectively encoded, thereby masking the selectively encoded portions. The media can then be shared, including the encoded portions, with a second client device. Using the first client device, an operation can be implemented for authorizing decoding of the portions of the media by the second client device, thereby allowing the decoded portions of the media to be rendered by the second client device without masking.

Abstract: A voltage-glitch detection and protection circuit and method are provided. Generally, circuit includes a voltage-glitch-detection-block (GDB) and a system-reset-block coupled to the GDB to generate a reset-signal to cause devices in a chip including the circuit to be reset when a voltage-glitch in a supply voltage (VDD) is detected. The GDB includes a voltage-glitch-detector coupled to a latch. The voltage-glitch-detector detects the voltage-glitch and generates a PULSE to the system-reset-block and latch.

In one embodiment, the latch includes a filter and a sample and hold circuit to power the latch, and ensure the PULSE_LATCHED signal is coupled to the system-reset-block when a voltage to the GDB or to the latch drops below a minimum voltage due to the voltage-glitch.
