11,312,129 | 0 | Getting a Date with "ShortenedMonth/dd" format <p>Is there a way I can get a date by the format "MM/dd" but instead of the month being an <code>int</code>, it is a shortened <code>string</code> like "Jan 30"?</p> <p>Currently I did this with Java by a simple <code>Switch Case</code>, but I want to know if this is already contained in a <code>DateFormat</code> or something similar.</p> <p>Anyway I leave here my current code. I used <code>R.string</code> because my application has multi-language support.</p> <pre><code>public void setShortMonth(){ final Calendar calendar = Calendar.getInstance(); int Month = calendar.get(Calendar.MONTH); String ShortMonth = " "; switch (Month){ case 0: ShortMonth = getString(R.string.Jan); break; case 1: ShortMonth = getString(R.string.Fev); break; case 2: ShortMonth = getString(R.string.Mar); break; case 3: ShortMonth = getString(R.string.Apr); break; case 4: ShortMonth = getString(R.string.May); break; case 5: ShortMonth = getString(R.string.Jun); break; case 6: ShortMonth = getString(R.string.Jul); break; case 7: ShortMonth = getString(R.string.Aug); break; case 8: ShortMonth = getString(R.string.Sep); break; case 9: ShortMonth = getString(R.string.Oct); break; case 10: ShortMonth = getString(R.string.Nov); break; case 11: ShortMonth = getString(R.string.Dec); break; } TextView datetxt = (TextView) findViewById(R.id.home_date); datetxt.setText(ShortMonth + " " + Day); } </code></pre> |

8,674,210 | 0 | <p>One thing you can do is to use the interface (i.e. the header files) and provide an implementation of your own, at least for those functions you care about. To switch between both versions essentially amounts to linking with different libraries: yours for testing, theirs for the real implementation.</p> <p>There are a few issues with that which can be addressed e.g. by only retaining the public interface and changing the private interface (on this case compilation needs to be directed at the different declarations, e.g. using different search pathes for the headers):</p> <ul> <li>often the stubbed version wants to store different data</li> <li>some object may need to construct private subobjects in specific ways</li> <li>inline function may call other functions you don't really want to implement</li> </ul> |

4,647,666 | 0 | CoreData programming with multiple Entities <p>I'm looking for some help with CoreData and with Entities in general. For the purpose of my question, lets say I have a database of albums. I simple have an entity named albums with Attributes for Name, Artist, Year, Album Art, and such.</p> <p>Now, lets say I want to be able to create songs for this album. I'm thinking I should have a separate Entity for the songs, and have a one-to-many relationship with it. However, I'm not sure exactly how I would do that.</p> <p>Since I have different albums which contain different songs, I want to separate the songs from AlbumA from Album B. Now, I could have a row in the songs database for which album it belongs to, but is that the most efficient way to do this. What if I have a duplicate album name. I tried creating a unique "hash" of the album name using the time created and the name, but is there a better way.</p> <p>I also need a better way to handle deletion for when an album is deleted. </p> <p>Without using one-to-many relationships, I was able to create two separate entities, Albums and Songs, which aren't linked together. However, when I create a new album, it loads a new viewcontroller and passes the "hashes" time-stamped album name to the viewcontroller. Then when I create a new song, it uses that hashed time-stamped album name as a row in the Songs entity. That way, when I'm viewing which songs are in the album, I just set an NSPredicate to only show queries which include the hashes time-stamp. However, deletion is a problem because their are no relationships. </p> <ol> <li>Should I be using a "one-to-many relationship"?</li> <li>How should I handle determining whether an song belongs to a certain album?</li> <li>What if their are multiple albums with the same name?</li> <li>How do I handle deletion?</li> </ol> <p>If anyone could provide answers, code, or tutorial for any of these… it would be greatly appreciated.</p> |

37,988,054 | 0 | <p>One solution is to create a version of your network that is truncated at the LSTM layer of which you want to monitor the gate values, and then replace the original layer with a custom layer in which the stepfunction is modified to return not only the hidden layer values, but also the gate values.</p> <p>For instance, say you want to access the access the gate values of a GRU. Create a custom layer GRU2 that inherits everything from the GRU class, but adapt the step function such that it returns a concatenation of the states you want to monitor, and then takes only the part containing the previous hidden layer activations when computing the next activations. I.e:</p> <pre><code>def step(self, x, states): # get prev hidden layer from input that is concatenation of # prev hidden layer + reset gate + update gate x = x[:self.output_dim, :] ############################################### # This is the original code from the GRU layer # h_tm1 = states[0] # previous memory B_U = states[1] # dropout matrices for recurrent units B_W = states[2] if self.consume_less == 'gpu': matrix_x = K.dot(x * B_W[0], self.W) + self.b matrix_inner = K.dot(h_tm1 * B_U[0], self.U[:, :2 * self.output_dim]) x_z = matrix_x[:, :self.output_dim] x_r = matrix_x[:, self.output_dim: 2 * self.output_dim] inner_z = matrix_inner[:, :self.output_dim] inner_r = matrix_inner[:, self.output_dim: 2 * self.output_dim] z = self.inner_activation(x_z + inner_z) r = self.inner_activation(x_r + inner_r) x_h = matrix_x[:, 2 * self.output_dim:] inner_h = K.dot(r * h_tm1 * B_U[0], self.U[:, 2 * self.output_dim:]) hh = self.activation(x_h + inner_h) else: if self.consume_less == 'cpu': x_z = x[:, :self.output_dim] x_r = x[:, self.output_dim: 2 * self.output_dim] x_h = x[:, 2 * self.output_dim:] elif self.consume_less == 'mem': x_z = K.dot(x * B_W[0], self.W_z) + self.b_z x_r = K.dot(x * B_W[1], self.W_r) + self.b_r x_h = K.dot(x * B_W[2], self.W_h) + self.b_h else: raise Exception('Unknown `consume_less` mode.') z = self.inner_activation(x_z + K.dot(h_tm1 * B_U[0], self.U_z)) r = self.inner_activation(x_r + K.dot(h_tm1 * B_U[1], self.U_r)) hh = self.activation(x_h + K.dot(r * h_tm1 * B_U[2], self.U_h)) h = z * h_tm1 + (1 - z) * hh # # End of original code ########################################################### # concatenate states you want to monitor, in this case the # hidden layer activations and gates z and r all = K.concatenate([h, z, r]) # return everything return all, [h] </code></pre> <p>(Note that the only lines I added are at the beginning and end of the function).</p> <p>If you then run your network with GRU2 as last layer instead of GRU (with return_sequences = True for the GRU2 layer), you can just call predict on your network, this will give you all hidden layer and gate values.</p> <p>The same thing should work for LSTM, although you might have to puzzle a bit to figure out how to store all the outputs you want in one vector and retrieve them again afterwards.</p> <p>Hope that helps!</p> |

One solution would be to first convert the images to 3-dimensional <a href="http://www.mathworks.com/help/toolbox/images/f14-13543.html#f14-20224">truecolor images</a> using the function <a href="http://www.mathworks.com/help/techdoc/ref/ind2rgb.html">IND2RGB</a>, then combine them using the function <a href="http://www.mathworks.com.au/help/techdoc/ref/cat.html">CAT</a>:</p> <pre><code>image1 = ind2rgb(image1,map1); %# Convert image 1 to RGB image2 = ind2rgb(image2,map2); %# Convert image 2 to RGB image3 = cat(2,image1,image2); %# Concatenate the images along dimension 2 </code></pre> <p>And now you can view <code>image3</code> as described above.</p> |

If you only want unique items in your set, implementing the Comparable interface and overriding equals() is what you want to do.

The render method on the collection calls delegateEvents() method.</p> <pre><code> ItineraryEditorView = Marionette.CollectionView.extend({ tagName: "div", emptyView: EmptyItineraryDayView, itemView: ItineraryDayView, initialize: function (options) { }, render: function() { Marionette.CollectionView.prototype.render.apply(this); this.delegateEvents(); }, }); </code></pre> <p>The view is swapped out by closing region:</p> <pre><code>plannerLayout.itineraryEditorRegion.close(); </code></pre> <p>Swapping in the view:</p> <pre><code>itineraryEditorView.delegateEvents(); plannerLayout.itineraryEditorRegion.show(itineraryEditorView); </code></pre> <p>Deletion of a model is done by listening to the bubbled up event from itemView to collectionView (works, no issues here)</p> <pre><code>itineraryEditorView.on("itemview:delete:day", function(childView, model) { days.remove(model); //days coll is passed in to coll view on instance creation holiday.save(); }); </code></pre> <p>I'd expect that this would be enough to ensure the the child itemViews in the collection view are removed/closed when a model is removed from the underlying days collection.

28,335,868 | 0 | <p><strong>Short answer:</strong> none, but you may feel like it is taking a few milliseconds depending on your processor speed and the amount of things angular need to check before it updates the HTML</p> <p><strong>Long answer:</strong> As soon as you update the model (well, at the end of the current javascript context), Angular will execute a digest cycle on which it will process all the $watchers (in this case <code>{{text}}</code> is a watcher over the <code>text</code> property). If a watcher has a different value than last time, it will run a new digest cycle, and so on, until all watchers are stable. Then it will process the HTML and updates all value, before the browser finally render the view. Hence from a "machine" point of view, it is immediate as in the same execution context: your browser will not render anything in between.</p> <p>Now if your code is asynchronous (like a call to some server), that "immediaticity" I have been talking about starts from the latest call to <code>$scope.$apply</code></p> |
