multithreading - How are Atoms implemented in Clojurescript? -


लिखने के लिए मुद्दों में: 

  user = & gt; (Def my-atom (atom 0)) # 'user / my-atom user = & gt; @ माइ-एटम 0 उपयोगकर्ता = & gt; (स्वैप! माइ-एटॉम इंक) 1 उपयोगकर्ता = & gt; @ माइ-एटम 1 उपयोगकर्ता = & gt; (स्वैप! माइ-एटॉम (एफ एन [एन] (* (+ एन एन) 2)) 4)   
 हम जानते हैं कि यह (क्लोज़र कार्यान्वयन में) है  
 दिलचस्प रूप से पर्याप्त, परमाणु, एक सिंटैक्टिक स्तर पर - भले ही जावास्क्रिप्ट रनटायम्स में कोई परमाणु संदर्भ नहीं है  
 मेरा प्रश्न यह है कि,  कैसे क्लॉजस्क्रिप्ट में एटम का कार्यान्वयन किया जाता है?  क्या वे सिर्फ एक वस्तु आवरण हैं?   
 
  
  स्वैप!  और  रीसेट!  के कार्यान्वयन की जांच करें आपको पता चल जाएगा:  
  (सेट! (.- राज्य ए ) नया   
   
 फिर,  सेट पर जाएं! , आप पाएंगे कि संकलक सिर्फ एक असाइनमेंट कथन का उत्सर्जन करता है:  
  (defmethod emit *: सेट! [{: Keys [target val env]}] (emit-wrap env (लक्ष्य "=" val)))    < / html>

python - how we can use ajax() in views.py in django? -

I have a little code here. Could you please tell me what this code really does? please. Here in the AJAX call: $ .ajax ({url: "{% url} upload_document '%}", type: "POST", data : {Csrfmiddletoken: document.getElementsByName ('csrfmiddletoken') [0] Price, Title: document.getElementById ('title'). Value, // document: document: document.getElementById ('document'),}, datatype: "Jason", success: function (feedback) {if (feedback == "true") {// success} other {// attachment errors}}}); How AJAX works in the Django and how we can see the AJAX request. Here is the idea of ​​my thoughts def upload_document (requested): Print request. POTT print request FILES if request.is_ajax (): If request.method == 'POST': form = UploadForm (request.POST, request.FILES, user = request.user) if form.is_valid (): Form.save () return HTTPPCS (SimpleJason Dumps ('True'), Mime Type = 'App / Jason') Other:...

matlab - Using loops to get multiple values into a cell -

I have 31 topics (S1, S2, S3, S4, etc.) 3 images in each topic, opposite 1 IMG, Contrast 2 IMG and Contrast 3 Are IMG I p In a NX1 cell named P, I would like to use a loop to get all the paths of contrasts from all the subjects: data / S1 / contrast1.img / S1 / contrast2.img data / S1 / contrast3.img data / s2 / contrast1.img data / S2 / contrast2.img Data / S2 / contrast3.img ... Data / S31 / contast3.img This is what I've tried: A = {'S1', 'S2', 'S3', ..., 'S31'}; % All topics C = {'contrast1.img', 'contrast2.img', 'contrast3.img'}; For each = P = cell (31 * 3,1) for each topic, the required contrast images: Length = A for Jammu = 1: Length (C) P {j} = spm_select ('FPList', Fullfile (data_path, q {i}) sprint ('% s', cell2mat (c))); % Of each topic is to select three contrast images, it works in my script, it is probably not 100% correct, because I had to simplify this example. End of ...

python - Sequence Pattern recognition with Pybrain -

Image
I am constantly trying to use recurrent neural networks to classify a series of data. To be more specific, I have a sequence of sensor reading (which is continuous over time), I have to learn an algorithm which can detect the state related to this pattern, given the readings change. Example: Time step_1: 1.4 Time step_2: 1 Time step_3: 0.8 State = New Sequence: Time Phase 1: 0.4 Time Phase 2: 0.3 Time Phase 3: 0.1 State = Sitting I actually have 12 censors, I'm just showing a sequence of numbers for convenience. (Numbers are not real, I'm just trying to fulfill this idea)! I am trying to make my network with PyBrain RNN, however, I can not get a Data Set Container that can detect it, like information I tried to use sequential data But after some testing I came to know that this number is the next element in the sequence of numbers. Here's how I prepare my dataset: self.alldata = SequentialDataSet (ds.num_features, 1) # Now add samples to the dat...
