荒凉一梦 提交于 2020-12-30 05:10:02
问题 I am trying to display a datetime field retrieved froma database in my razor file with the following: @Html.EditorFor(model => model.RequestDate); I know with 100% certainty the RequestDate is not null, as I examined the model that was passed in the view, and it was the date from the database. However, the datetime textbox still displays "mm/dd/yyyy". I don't know why it is not display the date. Any ideas? Thank you. Here is my model: [Display(Name = "Time")] [DataType(DataType.Date)] public

Razor complains when I put a closing div tag in a if clause

问题 I am trying to do this using Razor templating: @if(isNew) { <div class="new"> } ... @if(isNew) { </div> } The error is: cannot resolve the symbol 'div' Razor doesn't like the ending div tag inside the IF clause, how can I get this to work? Is there an escape I have to use? 回答1: Razor doesn't like it when you split start/end tags up like this as it can't parse the HTML properly, so you have to escape them as plain text: @if(isNew) { @:<div class="new"> } ... @if(isNew) { @:</div> } The more

向AI转型的程序员都关注了这个号 👇👇👇 大数据挖掘DT机器学习 公众号: datayx 决策树又称为判定树,是运用于分类的一种树结构,其中的每个内部节点代表对某一属性的一次测试,每条边代表一个测试结果,叶节点代表某个类或类的分布。 决策树的决策过程需要从决策树的根节点开始,待测数据与决策树中的特征节点进行比较,并按照比较结果选择选择下一比较分支,直到叶子节点作为最终的决策结果。 决策树的学习过程 特征选择:从训练数据的特征中选择一个特征作为当前节点的分裂标准(特征选择的标准不同产生了不同的特征决策树算法)。 决策树生成:根据所选特征评估标准,从上至下递归地生成子节点,直到数据集不可分则停止决策树停止声场。 剪枝:决策树容易过拟合,需要剪枝来缩小树的结构和规模(包括预剪枝和后剪枝)。 实现决策树的算法包括ID3、C4.5算法等。 ID3算法 ID3算法是由Ross Quinlan提出的决策树的一种算法实现,以信息论为基础,以信息熵和信息增益为衡量标准,从而实现对数据的归纳分类。 ID3算法是建立在奥卡姆剃刀的基础上:越是小型的决策树越优于大的决策树(be simple简单理论)。 奥卡姆剃刀(Occam's Razor, Ockham's Razor),又称“奥坎的剃刀”,是由14世纪逻辑学家、圣方济各会修士奥卡姆的威廉(William of Occam,约1285年至1349年
