This article translated from: http://developer.android.com/training/basics/firstapp/building-ui.html The graphical user interface of Android applications is built using the view and viewgroup object layers. Generally, view objects are some small UI windows, such as buttons and text fields. The viewgroup object is an invisible view container, which defines the layout of the Child view, such as in a grid or

Today, the GPU is used to speed up computing, that feeling is soaring, close to graduation season, we are doing experiments, the server is already overwhelmed, our house server A pile of people to use, card to the explosion, training a model of a rough calculation of the iteration 100 times will take 3, 4 days of time,

Today I read a Zhiyuan Liu Teacher team 2015 in the Summit IJCAI published the paper "Joint Learning of Character and Word embeddings", also have about in the word vector generation part has been improved, The paper introduces the information of the single Chinese character of word composition (mainly in Chinese), and improves the quality of word vector generation. Because model name is called "character-enhanced word embeddding Model", the model is a

Python Intensive Training Note (7)-use the deque queue and save the object as a file, The deque object in the collections module is a queue with the first-in-first-out principle for normal queues. We can use this object to save data. For example, the system starts to randomly roll a game with

towards our own life. The establishment of a life philosophy will give us greater motivation to pursue the life we want. Concepts are also divided into correct or wrong ideas. In the classroom, we will find that many students always stick to their own wrong ideas from time to time. At this time, we need a person to guide you on the way forward, it allows you to go farther and closer in your life. Master Xi

Subject address: Ultraviolet A 11134 This is because the rows and columns are irrelevant and have no impact on each other. Therefore, you can separate rows or columns for calculation. This is equivalent to converting to selecting n different integers in the period [1, N], so that the I-th integer is within the Closed range [Li, Ri. This is a greedy problem. However, note that you cannot sort by left endpoin

Today, I attended a unit test training held internally in Corp. Several gains: 1. Applying Unit Test is pretty simple! I never thought that the idea to do unit test and its implementation is just that straightforward and easy! Remember the key point of unit test is the drive to do it by ourselves instead of using popular 3rd party test framework like mstest, Google test, nunit, etc. yes, the key point is: u
