Predicting conversion rates (CVRs) in display advertising (e.g., predicting the proportion of users who purchase an item (i.e., a conversion) after its corresponding ad is clicked) is important when measuring the effects of ads shown to users and to understanding the interests of the users. There is generally a time delay (i.e., so-called delayed feedback) between the ad click and conversion. O...

In this paper, we propose a fast motion estimation algorithm to be used for motion-compensated frame rate up conversion (FRUC). The FRUC techniques are used to enhance the visual quality of the low frame rate video on display. By using the motion vectors obtained from motion estimation process, the new frames can be interpolated. The motion estimation is the key part of the FRUC process but it ...

One of the primary challenges in the development of the Advanced Receiver is the ability to accommodate a wide variety of possible data rates, motivated by the desire to support different missions for the Deep Space Network (DSN) under different adverse conditions. To conform to fixed architectures such as the analog-todigital converter (ADC) used at the front end and tracking loops used subseq...

In this paper, we present a video frame-rate up-conversion scheme that uses transmitted true motion vectors for motion-compensated interpolation. In past work, we demonstrate that a neighborhood-relaxation motion tracker can provide more accurate true motion information than a conventional minimal-residue block-matching algorithm. Although the technique to estimate the true motion vectors is a ...

Temporal compressions of optical pulses and pulse trains have been performed by the photon-echo process in Tm-doped YAG at 793 nm. Single-pulse temporal compression by almost a factor of 500 from 10 micros to 22 ns and pulse train compression by a factor of 14 from 5micros to 350 ns with a high-speed frequency-tunable external-cavity diode laser are demonstrated. It is suspected that significan...
