Abstract: An online system receives an image associated with a set of pixel values and provides the set of pixel values to a deep learning or machine-learned model that is trained to assign a set of regions of interest within the image to one or more classes. The model is structured to identify the set of regions of interest based on the pixel values, in which each region of interest is associated with an embedding corresponding to a vector representation of the region of interest. The online system compares each embedding to a database of embeddings associated with multiple labeled images, in which the labels indicate an identity of a brand and/or an obfuscated identity of the brand. The online system then determines whether the identity of the brand and/or the obfuscated identity of the brand is/are detected within each region of interest based on the comparison.

Abstract: Techniques for mitigating interference on the reverse link in a wireless communication system are described. Terminals interfering with one another and communicating with different sectors on the reverse link may be identified. The terminals may be scheduled in time intervals selected to mitigate interference. For example, each terminal may be scheduled on at least one pseudo-randomly selected time interval, on a pseudo-randomly selected interlace that includes evenly spaced time intervals, on a different set of at least one time interval, on a different interlace, etc. A terminal may receive an assignment of at least one time interval for transmission on the reverse link to a serving sector. The at least one time interval may be selected to mitigate interference to terminals in neighbor sectors.

Abstract: A method and circuit for adaptively estimating channel conditions of a pilot channel in a wireless communication system. The method includes estimating channel statistics of the pilot channel, and adaptively filtering the pilot channel in response to the estimated channel statistics. The estimation is performed by filtering a channel signal derived from the pilot channel to determine an estimated channel mean and an estimated channel covariance. In order to perform the adaptive filtering, the present invention partitions the pilot channel into one or more time slots and weights each time slot according to the channel statistics. Thus, an advantage of the present invention is that it automatically and continually updates the pilot filter parameters in order to optimize the pilot filter performance over a broad range of channel conditions.
