Retrofit2 tutorial and Android Network Architecture (original), retrofit2android Squareup has been releasing movie fit2 for some time. The current version is stable and there is no big pitfall. The tutorial on the network is either too simple, just a Demo; or some fall, or the reusability is poor, so I write a tutorial (alex9xu@hotmail.com) for your reference. 1

principle, that is, the site often access to so many things, for this very high-hit things need to be processed by the cache,Reducing the number of reads, the memcache in Ctrip do the "Data heat" operation, for low-heat data will be automatically kicked out of the cache.2. Write operationsThis is timely write and non-timely write, for non-timely write data, we can use "message queue" to the write operation throttling, thereby alleviating the instantaneous pressure of the database write.This tim

Preface Here I will explain the motivation, purpose, content, principles and usage of this document. I am mainly engaged in network development. The main technical solution I use is FreeBSD/Linux + MySQL/Oracle + JavaBean/EJB + Jsp, that is, the layer-4 structure (some people think it is a layer-3 structure, but the interface layer concept is added to J2EE ). During project development, server architecture

End-to-end neural network MT (end-to-end Neural machine translation) is a new method of machine translation emerging in recent years. In this paper, we will briefly introduce the traditional method of statistical machine translation and the application of neural network in machine translation, then introduce the basic coding-decoding framework (Encoder-decoder) in NMT.Reprint Please specify source: http://b

Android Network Architecture-OkHttp + Volley + Gson, okhttpgson Previously, HttpClient was encapsulated by itself. However, Volley is used for mainstream network requests, and OkHttp is also very popular. These frameworks are not introduced.

service and the service relationship is said to be the interface relationship.5. Open Systems Interconnection: Interactions between systems involve only the external behavior of the system and are independent of the structure and function within the system. Thus, any standard on interconnection systems is only a provision for the external characteristics of the system.6. Each open system consists of a number of contiguous subsystems, a hierarchy of subsystems on the same line as all interconnec

Mseloss loss function is called in Chinese. The formula is as follows: Here, the loss, X, and y dimensions are the same. They can be vectors or matrices, and I is a subscript. Many loss functions have two Boolean parameters: size_average and reduce. Generally, the loss function directly calculates the batch data. Therefore, the returned loss result is a vector with the dimension (batch_size. The general format is as follows: loss_fn = torch.nn.MSELoss(reduce=True, size_average=True) Note the fo
