Patent number: 11616666Abstract: A method performed by a communication device includes generating an initial channel estimate of a channel for a current time step with a Kalman filter based on a first signal received at the communication device. The method also includes inferring, with a neural network, a residual of the initial channel estimate of the current time step. The method further includes updating the initial channel estimate of the current time step based on the residual.Type: GrantFiled: June 16, 2021Date of Patent: March 28, 2023Assignee: Qualcomm IncorporatedInventors: Rana Ali Amjad, Kumar Pratik, Max Welling, Arash Behboodi, Joseph Binamira Soriaga

Publication number: 20230076290Abstract: A method for quantizing a pre-trained neural network includes computing a loss on a training set of candidate weights of the neural network. A rounding parameter is assigned to each candidate weight. The rounding parameter is a binary random value or a multinomial value. A quantized weight value is computed based on the loss and the rounding parameter.Type: ApplicationFiled: February 4, 2021Publication date: March 9, 2023Inventors: Rana Ali AMJAD, Markus NAGEL, Tijmen Pieter Frederik BLANKEVOORT, Marinus Willem VAN BAALEN, Christos LOUIZOS

Publication number: 20230058159Abstract: Various embodiments include methods and devices for joint mixed-precision quantization and structured pruning. Embodiments may include determining whether a plurality of gates of quantization and pruning gates are selected for combination, and in response to determining that the plurality of gates are selected for combination, iteratively for each successive gate of the plurality of gates selected for combination quantizing a residual error of a quantized tensor to a scale of a next bit-width producing a residual error quantized tensor in which the next bit-width increases for each successive iteration, and adding the quantized tensor and the residual error quantized tensor producing a next quantized tensor in which the next quantized tensor has the next bit-width, and in which the next quantized tensor is the quantized tensor for a successive iteration.Type: ApplicationFiled: April 29, 2021Publication date: February 23, 2023Inventors: Marinus Willem VAN BAALEN, Christos LOUIZOS, Markus NAGEL, Tijmen Pieter Frederik BLANKEVOORT, Rana Ali AMJAD

Patent number: 10961477Abstract: An additive composition for use in a fuel for a spark-ignition internal combustion engine comprises an octane-boosting additive and one or more further fuel additives. The octane-boosting additive has a chemical structure comprising a 6-membered aromatic ring sharing two adjacent aromatic carbon atoms with a 6- or 7-membered saturated heterocyclic ring, the 6- or 7-membered saturated heterocyclic ring comprising a nitrogen atom directly bonded to one of the shared carbon atoms to form a secondary amine and an atom selected from oxygen or nitrogen directly bonded to the other shared carbon atom, the remaining atoms in the 6- or 7-membered heterocyclic ring being carbon. The additive composition increases the octane number of the fuel, thereby proving the auto-ignition characteristics of a fuel.Type: GrantFiled: February 9, 2017Date of Patent: March 30, 2021Assignee: BP OIL INTERNATIONAL LIMITEDInventors: Rana Ali, Sorin Vasile Filip
