20 de ene. de 2024 · Transformer整体结构(输入两个单词的例子). 为了能够对Transformer的流程有个大致的了解,我们举一个简单的例子,还是以之前的为例,将法语"Je suis etudiant"翻译成英文。. 第一步:获取输入句子的每一个单词的表示向量 , 由单词的Embedding和单词位置的Embedding ...
二、何为 Transformer?. Transformer 架构擅长处理文本数据,这些数据本身是有顺序的。. 它们将一个文本序列作为输入,并产生另一个文本序列作为输出。. 例如,将一个输入的英语句子翻译成西班牙语。. Transformer 的核心部分,包含一个编码器层和解码器层的堆栈 ...
A power transformer is a device that converts alternating current from one voltage level to another, either to "step up" or "step down" voltages. The working principle is based on Faraday's law of electromagnetic induction. When an alternating current is applied to the primary coil, a magnetic field is created around the core.
A high voltage transformer is an electrical device that transfers electrical energy between two or more circuits through electromagnetic induction. It operates by stepping up (increasing) or stepping down (decreasing) the voltage levels in power systems. High voltage transformers are typically used in transmission and distribution networks to ...
Single-Phase Transformer Connections. Single phase transformers, like other electrical devices, may be connected into series or parallel arrangements. For example, distribution transformers are normally wound with the secondary or low-voltage windings that can be connected in series or parallel. The availability of primary voltages and the ...
Understanding transformer sizing is critical for optimal electrical system performance, safety, and efficiency. By considering the capacity, kVA rating, load calculation, voltage ratio, primary and secondary windings, impedance matching, efficiency, temperature rise, and short-circuit current, it is possible to select the ideal transformer size ...
7 de mar. de 2024 · Transformer模型通常采用 交叉熵损失函数 来度量预测结果与真实标签之间的差异。. 交叉熵损失函数可以定义为:. L = -∑ (y_true * log (y_pred)) 其中,y_true表示真实标签,y_pred表示模型的预测输出。. 交叉熵损失函数刻画了预测概率分布与真实概率分布之间的距离,是一 ...
A padmount transformer is a ground-mounted utility distribution transformer, which usually is housed in a locked metal cabinet, situated on a small concrete pad. These distribution transformers are normally located in residential subdivisions. Since all of the live contact points are enclosed in a grounded metal box, this kind of transformer ...
A Substation Transformer is designed for installation on three-phase transmission and distribution systems. Substation transformers are constructed for in-door or outdoor mounting on a concrete pad with high and low voltage cables entering operating compartments through enclosed sidewall mounted bushings (unit-type transformers) or through ...
Transformer 还能怎么优化. Transformer 是做什么的. transformer 是变形金刚,不是变压器,如果你看到一篇文章讲变压器怎么怎么样,那你可以直接呸一口,然后离开它。我特别痛恨那些不恰当的翻译,因为你看到它就知道这是一篇垃圾,完全没有看下去的必要。
