如下图所示
但我仍然担心我用来实现这些结果的一些“技术”。因此我来这里寻找如何提高代码（和设计）质量的想法。
首先，因为我想让“变换”箭头位于方框上方，所以我绘制了两次，第一次用作第二个方框（嵌入）的标签，第二次绘制在方框上方。我对这种方法感到不舒服。我将其标记为 UGLY HACK。
其次，我尝试使用来打破单词“think”后的节点（句子）\\，但没有成功，为了“修复”这个问题，我强制将文本宽度设置为给定的大小。
第三，如果我添加间距、更改文本或嵌入节点“内部”内容中的任何内容，我需要调整其大小。我知道这是有道理的，但我想知道是否有办法说：看，这些对象在你体内，放大以填充，尊重内部分隔符，优雅一点。
第四，为什么我需要在 (arrowc) 中使用更大的间距，为什么它不尊重全局 .15cm 的距离？
第五，为什么（嵌入）[我知道两个名字非常相似的盒子，抱歉] 盒子需要锚定到（arrowc.east）才能正确放置，为什么不锚定到（arrowc.south）？
最后，我如何将我的（矩阵）节点锚定到“center=of embeddings.center”，而不是手动选择位置？
此致
PS：当然，任何整体的改进都是受欢迎的。
答案1
对于丑陋的黑客 - 只需在两个框都绘制后绘制箭头 - 这样箭头就会覆盖两个框的边框

编辑--句子中断
align=left只需在标签框的定义中使用如下
\tikzstyle{mylbl} = [inner sep=0pt, color=blue!70, align=left ]
现在你可以使用\\它来拆分句子——当然对齐会偏离，因为"第一行有一个，但第二行没有，所以你可以phantom "在第二行添加一个，虽然不会打印出来，但会改善对齐。

EDIT2——用于扩大节点
使用tikzlibrary{fit}如下
\node[draw=teal, dashed,ultra thick, fit=(sentence) (arrowa)(arrowb) (cbow)(predict)] {};
如果你在里面的节点添加任何东西，它将自动放大
编辑--对于arrowc.east
旋转箭头时锚点也会旋转，因此当旋转 -90 度时，东锚点将取代南锚点
对于矩阵的放置-- 我再次建议使用 fit 库，以便它可以随矩阵扩展
您的问题与选择节点的位置有关
完成 MWE
