As optimizer plays an important role in learning process of deep CNN model, we have presented the effect of seven different optimizers on our deep CNN model in the application of HSI classification. The seven different optimizers used in this study are SGD, Adagrad, Adadelta, RMSprop, Adam, ...
例如,Momentum 通常用于计算机视觉的CNN 模型;Adam 用于自然语言处理的Transformer 模型;Adagrad 用于推荐系统。如果我们想在某个场景中利用优化器对模型做稀疏化,就必须更换优化器,这很可能会影响模型的效果。 方法介绍 Motivation 公式(1) 可以改写为如下形式: \begin{equation} x_{t+1} = \arg\min_{x} m_t...
(x). With RepOptimizer, the parallel batch norm (referred to as "fusion layer" in the RepGhostNet paper) can be removed even during training. Similar to RepVGG and RepOpt-VGG, we design the CSLA model by replacing the batch norm layers with constant or trainable scaling layers and the ...

there are problems in the performance that need to be mitigated. To alleviate these shortcomings, an improved variant called Lévy orthogonal learning ALO is developed, which enhances the efficacy of the core method with orthogonal learning strategy, Levy flight, and primary core mechanisms. To measu...
The recital of a convolutional neural network (CNN) is dependent on several things (i.e., optimization, weight initialization, network topology, batches and epochs and activation/loss function and learning rate), as well as on the quality of the input data and specific blend of these model ...
The proposed GWO_ViT_PSO_MLP model achieves outstanding accuracy, with 99.14% for 2-class CXR classification and 98.89% for 2-class CT classification, outperforming traditional CNN-based approaches such as ResNet34 (84.22%) and VGG19 (93.24%). Furthermore, it demonstrates superior performance in...
