Adaptive Boosting with Dynamic Weight Adjustment is an enhancement of the
traditional Adaptive boosting commonly known as AdaBoost, a powerful ensemble
learning technique. Adaptive Boosting with Dynamic Weight Adjustment technique
improves the efficiency and accuracy by dynamically updating the weights of the
instances based on prediction error where the weights are updated in proportion
to the error rather than updating weights uniformly as we do in traditional
Adaboost. Adaptive Boosting with Dynamic Weight Adjustment performs better than
Adaptive Boosting as it can handle more complex data relations, allowing our
model to handle imbalances and noise better, leading to more accurate and
balanced predictions. The proposed model provides a more flexible and effective
approach for boosting, particularly in challenging classification tasks.

Adaptive Boosting with Dynamic Weight Adjustment improves efficiency and accuracy in ensemble learning by dynamically updating instance weights based on prediction error, resulting in a more flexible and effective approach for boosting in challenging classification tasks.

Particle-based Variational Inference (ParVI) methods approximate the target
distribution by iteratively evolving finite weighted particle systems. Recent
advances of ParVI methods reveal the benefits of accelerated position update
strategies and dynamic weight adjustment approaches. In this paper, we propose
the first ParVI framework that possesses both accelerated position update and
dynamical weight adjustment simultaneously, named the General Accelerated
Dynamic-Weight Particle-based Variational Inference (GAD-PVI) framework.
Generally, GAD-PVI simulates the semi-Hamiltonian gradient flow on a novel
Information-Fisher-Rao space, which yields an additional decrease on the local
functional dissipation. GAD-PVI is compatible with different dissimilarity
functionals and associated smoothing approaches under three information
metrics. Experiments on both synthetic and real-world data demonstrate the
faster convergence and reduced approximation error of GAD-PVI methods over the
state-of-the-art.

Humans can naturally and effectively find salient regions in complex scenes.
Motivated by this observation, attention mechanisms were introduced into
computer vision with the aim of imitating this aspect of the human visual
system. Such an attention mechanism can be regarded as a dynamic weight
adjustment process based on features of the input image. Attention mechanisms
have achieved great success in many visual tasks, including image
classification, object detection, semantic segmentation, video understanding,
image generation, 3D vision, multi-modal tasks and self-supervised learning. In
this survey, we provide a comprehensive review of various attention mechanisms
in computer vision and categorize them according to approach, such as channel
attention, spatial attention, temporal attention and branch attention; a
