Use tf.nn.sparse_softmax_cross_entropy_with_logits, but beware that it can't accept the output of tf.nn.softmax. Instead, calculate the unscaled activations, and then the cost: logits = tf.matmul(state_below, U) + b cost = tf.nn.sparse_softmax_cross_entropy_with_logits(logits, labels) In this c...

Saving a model in tensorflow is pretty easy. Let's say you have a linear model with input x and want to predict an output y. The loss here is the mean square error (MSE). The batch size is 16. # Define the model x = tf.placeholder(tf.float32, [16, 10]) # input y = tf.placeholder(tf.float32, [16...

Restoring is also quite nice and easy. Here's a handy helper function: def restore_vars(saver, sess, chkpt_dir): """ Restore saved net, global score and step, and epsilons OR create checkpoint directory for later storage. """ sess.run(tf.initialize_all_...

For use TypeScript REPL in Node.js you can use tsun package Install it globally with npm install -g tsun and run in your terminal or command prompt with tsun command Usage example: $ tsun TSUN : TypeScript Upgraded Node type in TypeScript expression to evaluate type :help for commands in r...

Insert a document called 'myFirstDocument' and set 2 properties, greetings and farewell const MongoClient = require('mongodb').MongoClient; const url = 'mongodb://localhost:27017/test'; MongoClient.connect(url, function (err, db) { if (err) throw new Error(err); db.collection('myCollect...

.find() method allows us to search through the descendants of these elements in the DOM tree and construct a new jQuery object from the matching elements. HTML <div class="parent"> <div class="children" name="first"> <ul> ...

You can use the plus (+) operator to concatenate strings: 'Dart ' + 'is ' + 'fun!'; // 'Dart is fun!' You can also use adjacent string literals for concatenation: 'Dart ' 'is ' 'fun!'; // 'Dart is fun!' You can use ${} to interpolate the value of Dart expressions within strings. The curly...

A string can be either single or multiline. Single line strings are written using matching single or double quotes, and multiline strings are written using triple quotes. The following are all valid Dart strings: 'Single quotes'; "Double quotes"; 'Double quotes in "single" quo...

Programmatically generating a String is best accomplished with a StringBuffer. A StringBuffer doesn't generate a new String object until toString() is called. var sb = new StringBuffer(); sb.write("Use a StringBuffer"); sb.writeAll(["for ", "efficient ", "stri...

template <class InputIterator, class T> InputIterator find (InputIterator first, InputIterator last, const T& val); Effects Finds the first occurrence of val within the range [first, last) Parameters first => iterator pointing to the beginning of the range last => iterator p...

vmin: Relative to 1 percent of the viewport's smaller dimension vmax: Relative to 1 percent of the viewport's larger dimension In other words, 1 vmin is equal to the smaller of 1 vh and 1 vw 1 vmax is equal to the larger of 1 vh and 1 vw Note: vmax is not supported in: any version of Inte...

git log --pretty=format:"%Cgreen%ci %Cblue%cn %Cgreen%cr%Creset %s" This will give a nice overview of all commits (1 per line) with date, user and commit message. The --pretty option has many placeholders, each starting with %. All options can be found here

Arrow functions are lexically scoped; this means that their this Binding is bound to the context of the surrounding scope. That is to say, whatever this refers to can be preserved by using an arrow function. Take a look at the following example. The class Cow has a method that allows for it to pr...

xcrun uses the system default Xcode version (set via xcode-select) to locate and execute command line tools from the Xcode application bundle, e.g., llvm-cov. # Generate code coverage reports via llvm-cov # /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin xc...

Use Spliterators.spliterator() or Spliterators.spliteratorUnknownSize() to convert an iterator to a stream: Iterator<String> iterator = Arrays.asList("A", "B", "C").iterator(); Spliterator<String> spliterator = Spliterators.spliteratorUnknownSize(itera...

To initialize a static final fields that require using more than a single expression, a static initializer can be used to assign the value. The following example initializes a unmodifiable set of Strings: public class MyClass { public static final Set<String> WORDS; static {...

A JDK installation and a text editor are the bare minimum for Java development. (It is nice to have a text editor that can do Java syntax highlighting, but you can do without.) However for serious development work it is recommended that you also use the following: A Java IDE such as Eclipse, In...

It is possible to create a set of variables that can act similar to an array (although they are not an actual array object) by using spaces in the SET statement: @echo off SET var=A "foo bar" 123 for %%a in (%var%) do ( echo %%a ) echo Get the variable directly: %var% Result: ...

You can enhance your own classes with generics just like NSArray or NSDictionary. @interface MyClass<__covariant T> @property (nonnull, nonatomic, strong, readonly) NSArray<T>* allObjects; - (void) addObject:(nonnull T)obj; @end
