To reduce parameter overhead, the hidden activation size is set to $\mathbb{R}^{C/r×1×1}$, where $r$ is the reduction ratio. After the shared network is applied to each descriptor, we merge the output feature vectors using element-wise summation. In short, the channel attention is ...
We believe that each channel feature has different frequency components. In addition to the current low-frequency information, there is also valuable information in ALGORITHM 1 Parallel frequency channel attention. Input: Input Feature X ∈ ℝC ×H ×W ; Output: New Feature X̃c ∈ ℝC ...
(3.3 V) supplies ► Digital input/output (I/O) supply: 1.8 V to 3.6 V ► Performance temperature range: –40°C to +105°C ► Functional temperature range: –40°C to +125°C ► Performance ► Combined ac and dc performance ► 108 dB signal-to-noise ratio (SNR)/dynamic ...
A new attention deep feature framework is presented, which generates the attention map with multiplicative fusion as a clear input to drive the network focusing on discriminating regions and enhancing the classification accuracy. Authors in [35] adopt the self-attention with a generative adversarial ...
DCT has a strong energy compaction property [1, 30], so it could achieve high data compression ratio with high quality [2, 22]. This property meets the demand of the chan- nel attention that representing a channel with a scalar. 2) DCT can be implemented with an element-wise multiplica...
We now shift our attention to methods for achieving these limits, namely, to the design of coding schemes which approach channel capacity. The study of such coding schemes is typically referred to as coding theory, a subject described in many books, including MacWilliams and Sloane, 1977; ...
Another type of ion channel family that is the focus of recent attention in vascular smooth muscle is nonselective cation channels. The hallmark feature of these channels is their distinct but variable permeability to at least two cations, most notably Na+ and Ca2+. Ligand binding to G-protein...
Specially, the proposed cycleSimulationGAN constrains the structural similarity between the synthetic and input images for better structural retention characteristics. Additionally, we propose to equip a novel channel-wise attention mechanism based on the traditional generator of GAN to enhance the feature ...
The set of all possible sequences x is the channel code and the ratio c=k /n is called the code rate. The sequences u at the input of the encoder are called data words and the sequences x at the output of the encoder are called code words. Many decades of research have ...
