对于Transformer的结构,相信了解深度学习的人都知道。一个Transformer Bolck中主要包含三部分:MultiheadAttention(多头注意力)、FFN(前馈神经网络)和Add&Norm,其中的MultiheadAttention是由多层的self-attention搭建而来的,而FFN则是由两个线性变换层和激活函数组成的,具体结构如下所示: 图1 Transformer Block 这里对于Multi...
1、Encoder中的每一个Block中，在多头注意力层，计算Q，K，V，矩阵的的权重是共享的吗？还是说每一...
transformer中的norm？使用Layer Norm，而非Batch Norm，原因在于序列问题中，不同样本长度不同，基于单样本的统计信息难以反映全局分布，Layer Norm在单词维度间进行规范化。Decoder中的Q、K、V计算？Q由第一个mask自注意力机制输出，随block变化；K、V由Encoder编码信息得到，不随block变化。Encoder、Decod...
在这里,只需将 MultiHeadAttention 与 GroupedQueryAttention 互换,并添加新的 RoPE 设置: class TransformerBlock(nn.Module): def __init__(self, cfg): super().__init__() self.att = GroupedQueryAttention( # MultiHeadAttention( d_in=cfg["emb_dim"], d_out=cfg["emb_dim"], context_length=...

FIG. 1 is a block diagram of a known design of a control unit comprising a feedback compensator in cascade with a feed forward compensator; FIG. 2 is a schematic diagram showing a known design of a digital control unit arranged to control a digital pulse width modulator that generates switc...
Implementation of perfect-magnetic-coupling ultralow-loss transformer in RFCMOS technology In this paper, we propose a single-turn multiple-layer interlaced stacked transformer structure with nearly perfect magnetic-coupling factor (kIM 1) using ... YS Lin,HB Liang,YR Tzeng - IEEE 被引量: 23...
The control block diagram is shown in Figure 6, where G(s) is the feed-forward element. The output value of the feed-forward is increased with the difference value between the voltage reference and the bus voltage. Therefore, the feed-forward element can be set as a proportional control. ...
