初级中學（Junior High School）（注：日本称之为中學），是中等教育的階段之一。許多國家的教育部門將普通中學劃分為初級中學和高級中學，廣義的初級中學包括普通初級中學和初級職業學校，狹義的初級中學專指普通初級中學。其中，初級中學是學生在小學結束後接續進行的教育，而在初級中學這一個階段結束之後，下一階段將會是高級中學。
初級中學（Junior High School）在臺灣名為國民中學（簡稱國中），共三年；原亦稱“初級中學”（包括初級職業學校，Vocational Junior High School），因九年國民義務教育的實施而改名[1]。但未加入国民教育体系的私立独立学校仍称初中，如忠信学校初中部。雖然和國民小學分開，但在2000年代教改以後效仿美式學程的作法，将國中視為國小課程的延續，不再稱呼國一～國三，而改稱七年级～九年级（但部分學校仍然維持舊稱），之後可升學至高級中等學校、五年制專科學校，或進入軍事學校中正國防幹部預備學校[1]。

中等學校（Middle School、Intermediate School）是西方國家學制中，一種範圍涵蓋初等教育和中等教育的學校，提供學生兩種教育階段間的橋樑。其修業年限在不同州有不同的規定，有時可以互通。例如在一些政府或法令規定中，「中等學校」被稱為「初級中學」（Junior High School），有些則代表著不同於傳統的學制。

1 I having trouble getting my ResourceDictionary.MergedDictionaries to load from app.xaml. My WPF app has a static class with a Main defined and startup object set to it. Within Main I created an instance of App and run it. The override OnStartup fires and the mainwindow.cs InitializeComponent gives the error "Message "Cannot find resource named 'MaterialDesignFloatingActionMiniAccentButton'. If I put the resources in the mainwindow.xaml everything is fine, but I wanted them to load at the app level so I they are not in each page. Any help appreciated. public partial class App protected override void OnStartup(StartupEventArgs e) base.OnStartup(e); var app = new MainWindow(); var context = new MainWindowViewModel(); app.DataContext = context; app.Show(); from the Main.. var app = new App(); app.Run(); app.xaml.. <Application x:Class="GS.Server.App" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:...
up vote 2 down vote favorite There is a clear pattern that show for two separate subsets (set of columns); If one value is missing in a column, values of other columns in the same subset are missing for any row. Here is a visualization of missing data My tries up until now, I used ycimpute library to learn from other values, and applied Iterforest. I noted, score of Logistic regression is so weak (0.6) and thought Iterforest might not learn enough or anyway, except from outer subset which might not be enough? for example the subset with 11 columns might learn from the other columns but not from within it's members, and the same goes for the subset with four columns. This bar plot show better quantity of missings So of course, dealing with missings is better than dropping rows because It would affect my prediction which does contain the same missings quantity relatively. Any better way to deal with these ? [EDIT] The nullity pattern is confirmed: machine-learning cor...
