I'm using the limdu library found here (https://www.npmjs.com/package/limdu#binary-classification). I'm trying to combine the 'Multi-Label Classification' section with the 'Input Normalization' section to make the outputs all be lowercase, but I keep getting the following error:
/Users/nickbrinsmade/Desktop/limdutest/node_modules/limdu/classifiers/EnhancedClassifier.js:43
this.classifier = new opts.classifierType();

My code Is seen below:
var limdu = require('limdu');
var MyWinnow = limdu.classifiers.Winnow.bind(0, {retrain_count: 10});
var textClassifier = new limdu.classifiers.multilabel.BinaryRelevance({
binaryClassifierType: MyWinnow
});
intentClassifier = new limdu.classifiers.EnhancedClassifier({
classifierType: textClassifier, // same as in previous example
normalizer: limdu.features.LowerCaseNormalizer
}); //this declaration throws the error.
intentClassifier.trainBatch([
{input: {I:1,want:1,an:1,apple:1}, output: "APPLE"},
{input: {I:1,want:1,a:1,banana:1}, output: "BANANA"},
{input: {I:1,want:1,chips:1}, output: "CHIPS"}
]);
console.log(intentClassifier.classify({I:1,want:1,an:1,apple:1,and:1,a:1,banana:1}));

I am beginner in node.js.
I am trying to call a very basic addition module saved in C:\wks\guru99 with file name: Node_03_addition.js. The calling application is also saved in the same location with the name: app.js
Addition Module:
var exports = module.exports = {};
exports.addNumber=function(a,b)
{
return a+b;
};
Application File:
var Addition = require('/.Node_03_addition.js');
console.log(Addition.addNumber(1,2));
when I run the application in cmd using node app.js
I am receiving the error that Module is not found. Can someone please help me with where I am going wrong here.

I'm new to serverless and lambda so please see the handler.js function below.

Issue resolved when I specifically required the jquery-deferred module which can be found here: https://www.npmjs.com/package/jquery-deferred
You have confused jQuery with jQuery UI. In your model.js, replace:
var $ = global.jQueryUI;
With:
var $ = global.jQuery;
Deferred is a jQuery method, and not a jQuery UI feature.
I was about to make a program that reads NFC cards via NFC reader.
when I execute my program i get the following errros...

;
console.log('nfc.version(): ' + util.inspect(nfc.version(), { depth: null }));
// { name: 'libfnc', version: '1.7.0' }
console.log('nfc.scan(): ' + util.inspect(nfc.scan(), { depth: null }));
Any help would be really great..
This code snippet seems not work, why?
var acorn = require("./node_modules/acorn/dist/acorn_loose");
/* Extend default Acorn's methods.*/
acorn.pluginsLoose.testPlug = function(looseParser) {
looseParser.extend('finishNode', function(nextMethod) {
return function(node, type) {
console.log(node, type);
return nextMethod.call(this, node, type);
};
});
};
var res = acorn.parse_dammit("alert(1", {ecmaVersion: 6, plugins: {testPlug: true}});
console.log(res)
Give us next error:

Is it bug or I do something wrong?
Enviroment: idea intellij 16.
Update:
Chrome give the similar error.
var res = acorn.parse_dammit("alert(1", {ecmaVersion: 6, plugins: {testPlug: true}});
You need to use pluginsLoose instead of plugins here as well!
I'm trying to create a simple application to compile mustache templates into static pages server side, here's what I've got so far:
var view = {
title: "Joe",
calc: function () {
return 2+4;
}
};
var mustache = require("mustache");
var template = require("./home.template");
var output = mustache.to_html(template, view);
console.log(output);
And my template looks like:
{{title}} spend {{calc}}
Any suggestions as to what is causing this to fail?
Here is the complete error message:
home.template:1
} spend {{calc}}
^
module.js:437
var compiledWrapper = runInThisContext(wrapper, filename, true);

Use fs.readFile() to read your template in as a string. Require won't work unless it's requiring javascript code, not mustache code.
http://nodejs.org/api/fs.html#fs_fs_readfile_filename_encoding_callback
Edit
See if this works...
var mustache = require("mustache");
var fs = require("fs");
var view = {
title: "Joe",
calc: function () {
return 2+4;
}
};
fs.readFile('./home.template', 'utf-8', function (err, data) {
if (err) throw err;
var output = mustache.to_html(data, view);
console.log(output);
});
