Branch moved folder based on label or date

阅读更多关于 Branch moved folder based on label or date

问题 I've moved a folder in tfs using the "move" command but now I cannot create branches off the moved folder based on date or label (label was created when source was in the old folder). I can however create a branch based on "latest version". I get an error message "no items match in if I try to branch of a label. I'm guessing the label references files using the old folder before I moved it. I also get no files if I try to "get specific version" by either date or label. I've tried to roll back

Topic Modelling - Assign human readable labels to topic

阅读更多关于 Topic Modelling - Assign human readable labels to topic

问题 I want to assign human readable labels to the results of my topic modelling. Is there any software library or data set that I can use that takes these key words as an input, and returns a title to describe the topic. Example: Input: ["Church","Priest","God","Prayer"] Output: "Religion" Note: I want automatic label creation - Not manual like others have asked before. 回答1: See this paper by Jey Han Lau. He describes how to automatically generate labels using different sources and features. We

Double x-axis on a spider plot with Gnuplot

阅读更多关于 Double x-axis on a spider plot with Gnuplot

问题 I'm making a spider (or chart, polar, etc.) plot using Gnuplot. The code works properly, but in the output figure I get a duplicate positive x-axis (looking at the figure, you can observe that the line is darker) and also a duplication of labels. How can I solve that? The code is this: #!/usr/bin/env gnuplot unset border set polar set angles degrees set term pngcairo enhanced size 800,800 set output 'graph_eff_10_3_accuracy_spider.png' set xtics axis set ytics axis set grid polar 90 set style

问题 I have an SSRS bar chart the shows some data in a handful of category groups. It's pretty straightforward and looks like this: I've now got the need to segment each category into two series groups like so: So far so good however I need to display the ungrouped percentage data labels (i.e. the requirement is to continue to show the percentage of each combined category group, NOT the percentage of the series group). So I need the bar chart from the second image but the data labels from the

首先，声明本次笔记是来自biaoyansu.com表严肃老师的bootstrap课程视频。 1.基本知识： 1-1.首先，Html(理解：骨骼)、Css(理解：皮肤)、Js(理解：神经)分工不同。 1-2.然后，由于情况是递增的所以造成了上述三者代码量关系：Html<Css<Js。 1-3.对于上述三者代码量的关系，具体来说： (1).Html仅满足了填写内容功能(即内容有地方放)； (2).要实现内容更好看这在一开始是不行的但我们想让它行所以就定义了Css这一套标准从而让Css来控制网页样式； (3).有了更好看的界面之后我还想要一点功能比如说做一个"轮播"然后轮播里可以是图片也可以是Html然后轮播控制 3秒轮播一次这些都需要通过逻辑来实现，Html和Css都无法满足所以只好再开发个Js，由于需求更复杂也就导致了 Js更复杂因为Js要满足我们的需求。 2.栅格系统： 2-1.目的：用于分割页面中的宽度。 2-2.比较之前：首先：要实现页面中四个块级元素<div>内容在页面平铺开来，不能摞在一起显示。操作：给四个块级元素添加样式声明“宽度占母元素25%且向左浮动” 结果：四个块级元素<div>内容平铺在页面显示。操作：打开开发者工具(在右侧显示)然后缩小页面宽度，发现四个块级元素内容仍平铺开来显示。分析：像上述这种情况，那会给用户带来很大的不便(即一行一个单词)。
