scikit learn - Coefficients from multinomial logistic regression in sklearn -

-

मैं एक बहु-स्तरीय समस्या पर sklearn.linear_model.LogisticRegression चला रहा हूँ। मैं जो समझता हूं, प्रत्येक वर्ग के प्रत्येक सुविधा के लिए coef _ विशेषता का गुणांक गुणांक है मुझे जो समझ में नहीं आता है वह स्केलैर्न में व्याख्या है। उदाहरण के लिए, एसपीएसएस में आपको एक वर्ग को आधार के रूप में होगा और उसके बाद उस वर्ग के संबंध में बाधाओं का व्याख्या करना होगा, इसलिए आप वास्तव में एन -1 क्लास के गुणांक प्राप्त करेंगे। यह स्केलैन में ऐसा मामला नहीं है, जहां मैं प्रत्येक कक्षा के लिए गुणांक प्राप्त करता हूं।

एक विशेषता (चार वर्गों के लिए) के लिए एक्सपोनेंटिएटेड गुणांक उदाहरण हैं:

1.164 9 | 1.0660 | 0.9589 | 0.8607

क्या यह व्याख्या सही है: इस विशेषता के लिए एक यूनिट मूल्य में वृद्धि के साथ उस उदाहरण की संभावना को प्रथम श्रेणी में बढ़कर 16% बढ़ जाती है, फिर द्वितीय श्रेणी में ~ 7% तक और तीसरे के लिए घट जाती है और चौथी कक्षाएं?

इसके अलावा, मैं गुणांक के लिए पी-वेल की गणना कैसे कर सकता हूं?

apache - 504 Gateway Time-out The server didn't respond in time. How to fix it? -

-
Using a form submission on an embedded iframe , the customer downloads a compressed log file Requested.

c# - .net WebSocket: CloseOutputAsync vs CloseAsync -

-
We have a working ASP.NET Web API REST service, which is one of the methods of our controller, HTTPTTEX. .) Socket handler code looks something like this ... Public async task socket handler (AspNetWebSocketContext context) {_webSocket = context.WebSocket; ... while (! Cts.IsCancellationRequested) {WebSocketReceiveResult Results = _webSocket.ReceiveAsync (Input Segment, cts.Token) .Result; WebSocketsStateCollusocketState = _webSocket.State; If (result.MessageType == WebSocketMessageType.Close || currentSocketState == WebSocketState.CloseReceived) {// What should I use. CloseAysnc () or. CloseOutputAsync ()? _webSocket.CloseOutputAsync (WebSocketCloseStatus.NormalClosure, "Client Requested", cts.Token). Wait (); } If (currentSocketState == WebSocketState.Open) {...}}} .What is the difference between .CooseAsync () and CloseOutputAysnc ()? I tried both of them and they both seemed to work fine but some difference should be the same they both describe very similar to...

c++ - How to properly scale qgroupbox title with stylesheet for high resolution display? -

-
I am trying to apply a stylesheet for QGroupBox (QT4.8), which works on the normal screen ( 96 dpi) high resolution screen (Yoga 2 Pro, 3200x1800, 275 dpi, windows 8.1). The following style looks good on the 275 dpi screen, but the top margins on a regular 96 dpi screen are far too big. QGroupBox {border: 1px solid red; Range radius: 7px; Margin-top: 12x; } QGroupBox :: Title {subcontrol-origin: margin; Subcontrol-position: left above; Padding-left: 10px; Padding-right: 10px; } Changing the top-margin has an effect, but I did not get a proper setting which works on both screens. If I shorten the value, the content of the group box overlaps with the title on 275 dpi screen. I was also playing with units "East", "PX", "MX", "PT". Reading the document I would have guessed, "2 X" was the correct solution, which should be scaled with different screen resolutions. Without the stylesheet, the groupbox works well on both screens. ...
