趋泥行为
Multi tool use常見於蝴蝶，其他動物也會有此行為，其中主要是昆蟲。他們會尋找湿润的物質，如腐爛的植物、泥土和腐肉[1]，去吸取其中的液體。所以昆蟲（如蝴蝶）常常會在潮濕的土壤、糞便或腐肉上聚集。從物質中獲得的營養物質，如鹽和氨基酸，在他們的生理上、行為上和生態上扮演重要角色[2][3] 。一些其他昆蟲也會有此行為，如葉蟬與馬鈴薯小綠葉蟬[4]
。
鱗翅目（像是蝴蝶和飛蛾）是常常有多種策略來收集液體和營養物。通常，趨泥行為會發生在有潮濕泥土的地方，甚至血、淚與汗也會對蝴蝶有吸引力。並不只有鱗翅目有類似的行為，例如，蜜蜂也會被汗和眼淚吸引。有些物種只有雄性有趨泥行為。

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...
