Categories at the tail end often need to be better learned. To address these challenges, we propose the AIR-YOLO-pruned method, a lightweight UAV-based object detection method built on the YOLOv8. In this paper, we propose the AIR-YOLO which is suitable for small object detection. We introduce the gradient adaptive allocation loss to enhance the model's learning ability for tail categories. To eliminate redundant components in AIR-YOLO, we design a kind of structured pruning strategy.

We introduce a goal-biased strategy that divides the sampling process of RRT* into two stages: exploration and convergence. A dual-input single-output fuzzy controller dynamically adjusts the goal-bias based on obstacle changes and the distance to the target. The paper also proposes a directed node generation approach to enhance the algorithm's adaptability and purposefulness during the exploration stage.

First, each node compresses the multiple speech signals into a single-channel signal and broadcasts it to other nodes. Then, each node reconstructs the new observations and estimates the corresponding part of the network-wide steering vector by using generalized eigenvalue decomposition and a matrix inversion. Finally, the updated steering vectors are compressed into a single-channel signal for computing the local filter coefficients of MVDR. The method is iteratively performed, and in each iteration, we simultaneously estimate the steering vectors and generate the asymptotically optimal centralized MVDR beamformer.
