看起来您的不确定性被低估了。如果您的数据(类似于高斯至高精度)接近0,则不确定性约为值的10倍。在峰附近,不确定性约为该值的3%。但是,如果数据确实具有如此不确定性,那么您会期望实际数据的差异会有所不同。您可以通过模拟预期幅度和宽度的高斯来测试,并添加5.e-5左右的假噪声(例如,使用numpy.random.normal.normal(scale = 5.e-5,size size) = len(x)

。 〜SQRT(0.03385)〜0.18

。减少了卡方,基本上是为了避免使用非常刻度的不

是的,统计数据“ Akaike Info Crit”和“ Bayesian Info Crit”是与“减少卡方”相似的替代统计信息,这些角色对于与不同数量的参数进行比较都特别有用。

It sort of looks like your uncertainties are underestimated. Where your data (which resembles a Gaussian to high precision) is near 0, the uncertainty is about 10x of the value. Near the peak, the uncertainty is about 3% of the value. But if the data really had such uncertainty, you would expect a lot more variation in the actual data. You could test that by simulating a Gaussian with your expected amplitude and width and adding fake noise with a size of 5.e-5 or so (eg using numpy.random.normal(scale=5.e-5, size=len(x)). I think you'll see that your actual data is not that noisy.

Just based on your value of reduced chi-square, you might guess that the uncertainties should be scaled by a factor of ~ sqrt(0.03385) ~ 0.18. That is that the uncertainties should be 5x to 6x what you have them.

FWIW, that won't change the estimated uncertainties in the parameters: those are automatically (well, by default) scaled by the sqrt of reduced chi-square, basically to avoid this problem of needing very well-scaled uncertainties.

1- Does my model is right to consider the experimental uncertianites 
of the data in the fitting model?

Yes, I think so. I think the scale is just off.

2- How can I scale the reduced R^2 to go around 1? as I readed, I 
have to find a better scalling, but if i am dealing with several 
fit models, should i scale each one independently or all of them 
should have the same scalling?

scaling your uncertainties by a factor of 1/5 to 1/6 will help.

3- Is there any other statistcal parameters to determine the 
best fit model between several fit models other than the 
reduced R^2 such as the Coefficient of determination?

Yes, the statistics "Akaike info crit" and "Bayesian info crit" are alternative statistics that serve similar roles to "reduced chi-square". These are all particularly useful for comparing fits with a different number of parameters.

因此,为此,我实际上发现问题是在OpenXR屏幕下的项目设置中,您可以关闭运行时调试器,它可以解决问题,特别是如果您需要

项目设置中的空间意识选项XR插件管理Management openXR OpenXR关闭运行时调试器

so for this i actually found the issue was within the project settings under the openxr screen you can turn off the runtime Debugger it fixes the issue especially if you need the spatial awareness options

In project settings xr plug-in management openxr turn off the runtime debugger

仅使用控制器名称作为路线不是一个好主意。但是,如果您仍然需要它,请尝试使用操作路由

[Route("~/GetOptions")]  
public IActionResult GetOptions()

it is not a good idea to use only controller name as a route. But if you still want it, try to use action routing

[Route("~/GetOptions")]  
public IActionResult GetOptions()

如果您来自C/C ++,那么基本上这样考虑它也可能会有所帮助:

// Rust          C/C++
    a: &T     == const T* const a; // can't mutate either
mut a: &T     == const T* a;       // can't mutate what is pointed to
    a: &mut T == T* const a;       // can't mutate pointer
mut a: &mut T == T* a;             // can mutate both

您会注意到这些是彼此的反相。 C/C ++采用“黑名单”方法,如果您想让某事变得不可变,您必须如此明确地说,而Rust采用“白名单”方法,如果您希望某事可变,您必须如此明确地说。

If you're coming from C/C++, it might also be helpful to think of it basically like this:

// Rust          C/C++
    a: &T     == const T* const a; // can't mutate either
mut a: &T     == const T* a;       // can't mutate what is pointed to
    a: &mut T == T* const a;       // can't mutate pointer
mut a: &mut T == T* a;             // can mutate both

You'll notice that these are inverses of each other. C/C++ take a "blacklist" approach, where if you want something to be immutable you have to say so explicitly, while Rust takes a "whitelist" approach, where if you want something to be mutable you have to say so explicitly.

放置“ mut”之间的区别是什么在变量名称之前,然后在“:”之后。

这有点晚了,但我目前正在寻找相同的解决方案,我发现了这一点:将多种MIME类型传递到ActivityResultlauncher.launch()
它像魅力一样解决了我的问题。希望这对人们将来遇到这个问题有帮助。

This is a bit late but I am looking for the same solution currently and I found this: Passing Multiple Mime Types to ActivityResultLauncher.launch()
It solved my problem like a charm. Hope it's helpful for people ran into this problem in the future.

结合我的和 theo 对可能的解决方案的有用评论:

import-module sqlserver;
$TargetInstanceName = "localhost\default"
$TargetFolderName = "FolderForTesting";
$ProjectName = "ProjectTesting";

try {
    $catalog = Get-Item SQLSERVER:\SSIS\$TargetInstanceName\Catalogs\SSISDB\  
    $folder = $catalog.Folders[ $TargetFolderName ]
    $project = $folder.Projects[ $ProjectName ]

    if($null -eq $project){
        Return 0
    } else {
        $project.Refresh()  # Causes an exception if project actually doesn't exist
        Return 1            
    }
}
catch {
    return 0
}

这是基于刷新SQL Server PowerShell提供商 ps + sqlps'> ps + sqlps刷新SQL Server对象和您自己的测试。我找不到有关该主题的任何官方信息。

Combining mine and Theo's helpful comments into a possible solution:

import-module sqlserver;
$TargetInstanceName = "localhost\default"
$TargetFolderName = "FolderForTesting";
$ProjectName = "ProjectTesting";

try {
    $catalog = Get-Item SQLSERVER:\SSIS\$TargetInstanceName\Catalogs\SSISDB\

        Return 1            
    }
}
catch {
    return 0
}

This is based on Refreshing the SQL Server PowerShell Provider and PS + SQLPS refreshing the SQL Server object and your own testing. I couldn't find any official information regarding the topic.

我可以说这是90%解决的

我在这个问题中遇到的问题与我观点的上下文有关,以及在@mohamed的回答和一些谷歌搜索和尝试之后,我使视图最终起作用,并且将文件保存到服务器和数据库中,并将SATGE对象的ID作为融洽的ID作为属性satge_id的ID,然后将用户重定向到另一页,

是我进行的修改

class RapportsCreateView(CreateView):
    model = Rapports
    form_class = RapportsForm
    template_name = "rapport/depo.html"

    def form_valid(self, form):
        self.stage_id = self.kwargs['pk']
        stage = Stages.objects.get(id=self.stage_id)
        form.instance.stage_id = stage.id
        form.instance.r_soummit = timezone.now()
        return super().form_valid(form)

    def get_context_data(self, **kwargs):
        context = super().get_context_data(**kwargs)
        stage = Stages.objects.get(pk=self.kwargs.get('pk'))
        context['stage'] = stage
        context['stage_id'] = stage.id
        return context

def get_absolute_url(self):
        return reverse("rapport:det_rpt", kwargs={"pk": self.pk})

def __str__(self):
        return self.src

i can say it is 90% Solved

the problem i had in this question was related to the context in my view and after the answer of @mohamed and some googling and tries i made the view ended up working and saving the file to the server and the database and putting the id of the Satges object as the id of rapport as the attribute satge_id then redirects the user to an other page

here are the modifications i made

views.py

class RapportsCreateView(CreateView):
    model = Rapports
    form_class = RapportsForm
    template_name = "rapport/depo.html"

    def form_valid(self, form):
        self.stage_id = self.kwargs['pk']
        stage = Stages.objects.get(id=self.stage_id)
        form.instance.stage_id = stage.id
        form.instance.r_soummit = timezone.now()
        return super().form_valid(form)

    def get_context_data(self, **kwargs):
        context = super().get_context_data(**kwargs)
        stage = Stages.objects.get(pk=self.kwargs.get('pk'))
        context['stage'] = stage
        context['stage_id'] = stage.id
        return context

models.Rapports

def get_absolute_url(self):
        return reverse("rapport:det_rpt", kwargs={"pk": self.pk})

def __str__(self):
        return self.src

任务窗格将是以非模式方式显示任何信息的好选择(请参阅 https://learn.microsoft.com/en-us/visalsto/visualsto/vsto/walkthrough-displaying-custom -task-panes-with-e-me-messages-in-inlook?view = vs-2022 )。

请注意,与Outlook表单区域不同,任务窗格可让您完全控制它们的显示和隐藏。

Task panes would be a good option for displaying any information in a non-modal fashion (see https://learn.microsoft.com/en-us/visualstudio/vsto/walkthrough-displaying-custom-task-panes-with-e-mail-messages-in-outlook?view=vs-2022).

Note that unlike Outlook form regions, task panes give you full control over when they are shown and hidden.

如果我正确理解您的要求,我假设您在一个页面中都有两个组件,并且您想从engering.vue.vue eferting> engeringlist.vue 反应性(不刷新路线)。如果是的,则可以通过在成功承诺的axios.post上调用getMessages()方法来实现这一目标,然后在extinglist.vue.vue中传递结果。

演示(我刚刚使用VUE 2创建它,您可以按照VUE 3进行相应更改它:

Vue.component('child', {
  // declare the props
  props: ['msglist'],
  // just like data, the prop can be used inside templates
  // and is also made available in the vm as this.message
  template: `<div>
              <div v-for="(message, index) in msglist" :key="index">
                <h3>{{ message.name }}</h3>
                <p>{{ message.greeting }}</p>
                <hr/>
              </div>
             </div>`
});

var app = new Vue({
  el: '#app',
  data: {
    messages: {
      name: null,
      greeting: null
    },
    // For demo, I am just mock data for initial greeting listing.
    messageList: [{
        name: 'Alpha',
        greeting: 'Hi !'
      }, {
        name: 'Beta',
        greeting: 'Hello !'      
      }]
  },
  methods: {
    store() {
        // Post API call will happen here.
      // on success, make a call to get list of greetings.
      if (this.messages.name && this.messages.greeting) {
        this.getMessages();
      }
    },
    getMessages() {
        // Get API call will happen here. For demo, I am just using the mock data and pushing the newly submitted greeting in a exisiting messageList.
      this.messageList.push({
        name: this.messages.name,
        greeting: this.messages.greeting
      })
    }
  }
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.17/vue.js"></script>
<div id="app">
  <input type="text" placeholder="Name" v-model="messages.name"/>
     <textarea cols="28" rows="10" placeholder="Greeting" v-model="messages.greeting"></textarea>
     <button @click="store">Submit</button>
  <child :msglist="messageList">
  </child>
</div>

If I understood your requirement correctly, I am assuming you have both the components in a single page and you want to get the details of newly added greeting from Greeting.vue in the GreetingList.vue reactively (without refreshing the route). If Yes, You can achieve that by calling a getMessages() method on successfully promise of axios.post and then pass the results in the GreetingList.vue.

Demo (I just created it using Vue 2, You can change it accordingly as per Vue 3) :

Vue.component('child', {
  // declare the props
  props: ['msglist'],
  // just like data, the prop can be used inside templates
  // and is also made available in the vm as this.message
  template: `<div>
              <div v-for="(message, index) in msglist" :key="index">
                <h3>{{ message.name }}</h3>
                <p>{{ message.greeting }}</p>
                <hr/>
              </div>
             </div>`
});

var app = new Vue({
  el: '#app',
  data: {
    messages: {
      name: null,
      greeting: null
    },
    // For demo, I am just mock data for initial greeting listing.
    messageList: [{
        name: 'Alpha',
        greeting: 'Hi !'
      }, {
        name: 'Beta',
        greeting: 'Hello !'      
      }]
  },
  methods: {
    store() {
        // Post API call will happen here.
      // on success, make a call to get list of greetings.
      if (this.messages.name && this.messages.greeting) {
        this.getMessages();
      }
    },
    getMessages() {
        // Get API call will happen here. For demo, I am just using the mock data and pushing the newly submitted greeting in a exisiting messageList.
      this.messageList.push({
        name: this.messages.name,
        greeting: this.messages.greeting
      })
    }
  }
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.17/vue.js"></script>
<div id="app">
  <input type="text" placeholder="Name" v-model="messages.name"/>
     <textarea cols="28" rows="10" placeholder="Greeting" v-model="messages.greeting"></textarea>

将您的样式表更改为

<?xml version="1.0" encoding="ISO-8859-1"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" version="1.0" encoding="UTF-8" omit-xml-declaration="yes" />

    <xsl:template match="@*|node()">
        <xsl:copy>
            <xsl:apply-templates select="@*|node()" />
        </xsl:copy>
    </xsl:template> 

    <xsl:template match="CONTENT|*[@TYPE='NODE']">
        <NODE DESC="{name()}">
            <xsl:apply-templates select="@*[not(name()='TYPE')]|node()" />          
        </NODE>
    </xsl:template>

</xsl:stylesheet>

预期的输出。如果使用名称空间,则可能应该将name() s更改为local-name()

Change your stylesheet to

<?xml version="1.0" encoding="ISO-8859-1"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" version="1.0" encoding="UTF-8" omit-xml-declaration="yes" />

    <xsl:template match="@*|node()">
        <xsl:copy>
            <xsl:apply-templates select="@*|node()" />
        </xsl:copy>
    </xsl:template> 

    <xsl:template match="CONTENT|*[@TYPE='NODE']">
        <NODE DESC="{name()}">
            <xsl:apply-templates select="@*[not(name()='TYPE')]|node()" />          
        </NODE>
    </xsl:template>

</xsl:stylesheet>

The output should be as expected. If you use namespaces, you should probably change the name()s to local-name().

请注意,地图的索引运算符不是恒定操作(对于std :: Map访问为O(log(n)))。因此,在这里,您需要两次支付此费用 - 查找和第二次返回值(如果有)。一种更好的方法是存储发现的结果:

std::map<std::string,std::map<std::string,float>>::iterator by_date_it = registration_by_date_time.find(date);
// or auto by_date_it = registration_by_date_time.find(date);
if (by_date != registration_by_date_time.end()) {
  std::map<std::string,float>::iterator by_time = by_date_it->second.find(time);
  if (by_time != by_date_it->end()) {
    return by_time->second;
  }
}
return "NaN;

正如指出的那样,此代码不仅较短,而且应该更快,避免使用CODED> o(log> o(log(n))的双重访问,这两个外部和内图。通常,我建议您可以在此处使用自动来使代码缩短,我已经明确地写出了该类型,希望使逻辑更清晰。

注意:STD :: MAP未使用hashmap实现,它是用红黑树(一种二进制搜索树)实现的,因此这可能使您认为访问的复杂性具有预期的恒定恒定复杂性。

Note that the index operator for map is not a constant operation (for std::map access is O(log(n))). So here you pay this cost twice - once for the find and second time to return the value (if available). A better approach is to store the result of find:

std::map<std::string,std::map<std::string,float>>::iterator by_date_it = registration_by_date_time.find(date);
// or auto by_date_it = registration_by_date_time.find(date);
if (by_date != registration_by_date_time.end()) {
  std::map<std::string,float>::iterator by_time = by_date_it->second.find(time);
  if (by_time != by_date_it->end()) {
    return by_time->second;
  }
}
return "NaN;

As pointed out, not only is this code shorter but it should be faster, avoiding double access with cost O(log(n)) for both the outer and the inner map. In general as I suggest you can use auto here to make the code shorter, I have written out the type explicitly in hope to make the logic clearer.

NOTE: std::map is not implemented with a hashmap, it is implemented with red-black trees (a type of binary search tree), so it is possible this is what led you to think the complexity of access is with expected constant complexity.

添加labels =(0,) in exp = eplainer.explain_instance()可能可以解决您的问题。

exp = interpretor.explain_instance(
data_row=x_test_scaled[:1], ##new data
predict_fn=model.predict,
num_features=11,
labels=(0,)
)

我在试图预测良性或恶性肿瘤的乳腺癌数据上也有类似的问题。包含记录的样本的列标题为benign_0_malignant_1,每行放置0或1。

Adding labels=(0,) in exp = eplainer.explain_instance() might resolve your issue.

exp = interpretor.explain_instance(
data_row=x_test_scaled[:1], ##new data
predict_fn=model.predict,
num_features=11,
labels=(0,)
)

I had a similar issue with breast cancer data trying to predict benign or malignant tumors. The column that contains the recorded sample is titled benign_0_malignant_1 with either 0 or 1 placed in each row.

此问题通常是由应用程序级问题引起的,例如缓慢的网络请求,效率低下的应用程序代码或数据库查询,高内存/CPU使用情况或由于错误而导致的应用程序崩溃。

您用来填充表的查询取决于数据库中运行的作业。如果DB1中有不同的作业与DB2中的作业不同,则您的查询可能会产生不同的结果。

如果您只是想获取数据库中的用户列表,则可以使用从dba_users中选择用户名

The query that you are using to populate the table is dependent on the jobs that have been run in the database. If there are different jobs running in DB1 than in DB2, then your query will likely have different results.
