In this article we will cover one of the most influential attention mechanisms proposed in computer vision: channel attention, as seen in Squeeze-and-Excitat…
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 ...
Following Figure 2.1, the encoder is in charge of setting a one-to-one correspondence between input sequences u of k bits and output sequences x of n bits (omitting the interleaver). The set of all possible sequences x is the channel code and the ratio c=k /n is called the ...
Secondly, based on a local cross-channel interaction strategy, a lightweight efficient channel attention mechanism (LECA) is designed. The kernel size of 1D convolution is affected by channel number and coefficients. Multi-scale feature input is used to retain more detailed features of different ...
The ratio bit rate/bandwidth measured in bps/Hz is called the spectral efficiency, which typically ranges between 0.5 and 8.0. The maximum value of the achievable spectral efficiency is given by Shannon's theorem as a function of the noise in the communication channel. When bandwidth is scarce...
During the feature reconstruction process, the attention decoder effectively utilizes inter-channel correlation information to suppress noise diffusion and focuses the model’s attention on anomalous key regions, thereby improving the reconstruction error of anomalous samples. We conduct extensive experiments ...
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...
(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 ...
processing sub-system can be judged by the required power or (optical) signal-to-noise ratio ((O)SNR) required at the receiver, with or without the new sub-system in place. In some cases, the new sub-system will be required to improve required power or OSNR. In other cases, the sub...
Fig. 3. Diagram of our shuffle efficient channel attention (sECA) module (k = 3). The computational steps of the sECANet module can be mathematically expressed as follows. Let the input of sECANet block be the feature map X∊RW×H×C, where W, H, and C are the width, the height...
