The present subject matter discloses a method (700) for estimating a pose of a first sensor at a measurement timestamp of a second sensor operating asynchronously with the first sensor. The method (700) includes receiving a plurality of inputs comprising a plurality of timestamped poses of the first sensor within a predetermined time window, one or more motion-state measurements from a third sensor operating at a higher sampling rate than the first sensor, and a query timestamp corresponding to a measurement of a second sensor. The method (700) includes determining a baseline pose of the first sensor at the query timestamp by computing a closed-form interpolation between the plurality of timestamped poses of the first sensor. The method (700) includes generating a pose residual relative to the baseline pose, an uncertainty estimate associated with the pose residual, and an estimate of timestamp-noise level based on the plurality of inputs. The method (700) includes determining a synchronization-quality gating value as a continuous monotonic function of the timestamp-noise level, to be applied to scale the pose residual to produce a scaled pose residual. The method (700) includes combining the scaled pose residual with the baseline pose to generate a predicted pose corresponding to the query timestamp. The method (700) includes outputting the predicted pose, the uncertainty estimate, and the estimate of the timestamp-noise level. (FIG. 7)

The present subject matter relates to a system and method for reinforcement learning based dynamic frequency scaling in a field programmable gate array based platform. The system 100 includes a custom hardware intellectual property (IP) core 101 implemented in programmable logic, whose operational performance scales with clock frequency. A programmable multi-output clock generation module 102 produces multiple discrete clock signals from a single stable reference clock, which are managed by a clock wrapper module 103. A PL-side clock controller 104 dynamically selects and applies a selected clock signal to the custom hardware IP core 101 during runtime. Real-time performance metrics are measured by a performance monitoring and feedback mechanism 105 and transmitted to a processing system 105 executing a reinforcement learning engine 107. Based on the received feedback, the reinforcement learning engine 107 determines an operating clock frequency that optimizes a power–performance tradeoff and generates frequency control commands. The reinforcement learning engine 107, performance monitoring and feedback mechanism 105, and PL-side clock controller 104 collectively form a closed-loop adaptive control system enabling real-time dynamic adjustment of programmable logic operating frequency.

The present subject matter discloses a method for determining an optimal kernel size in a CNN model. The method includes defining a plurality of parameters of the CNN model. The method includes selecting a range of kernel sizes. The method includes creating a distinct variant for each kernel size. The method includes training the distinct variant for each kernel size on a target dataset to generate a unique set of trained weights for each distinct variant. The method includes injecting one or more random bit-flip errors in at least one trained weight across a range of BERs. The method includes evaluating a functional performance of the at least one trained weight corrupted with the one or more random bit-flip errors on a validation set to generate performance data. The method includes comparing a performance of the distinct variant of each kernel size at each BER to identify a high performing kernel size amongst the one or more kernel sizes with respect to a robustness and a stability.
