Zhang等人(2019b)在DenseNet上进行了注意力机制的探索,首先构建了通道特征重标定密集连接卷积神经网络(channel feature reweight DenseNet,CFR-DenseNet),使用挤压激励模块对通道特征重标定,随后构建了层间特征重标定密集连接卷积神经网络(inter-layer feature reweight DenseNet,ILFR-DenseNet),使用双挤压激励模块对层间特...
No bias decaytx提出了只对卷积层和全连接层的weight做L2中正则化,不对bias,BN层的γ和β进行正则化衰减。文章还提及了分布式训练layer-wise adaptive learning,不过文章仅仅关注2k以内的batchsize训练。batch变大时学习率也需要变大,这样会导致收敛不稳定,LARS通过给LR乘上权重与梯度的norm比值来解决这个问题 weight...
Arbitrary CNNs can perform the hierarchical classification by adding the proposed layer. The training of a coarse-to-fine CNN is end-to-end, it can be optimised by typical stochastic gradient descent. In the test phase, it outp...

CNNs are defined using the Conv2D layer. model = Sequential([ Conv2D(filters=32,kernel_size=(3,3), input_shape = (200, 200, 3),activation='relu'), MaxPooling2D(pool_size=(2,2)), Conv2D(filters=32,kernel_size=(3,3), activation='relu'), MaxPooling2D(pool_size=(2,2)), ...

Because of this assumption, conventional machine learning methods do not consider feature/data correlation in the learning process. Nearly all traditional machine learning methods, including multi-layer neural networks and randomized learning methods, such as stochastic configuration networks (SCNs) [47],...
