Ⅵ 遷移學習與fine-tuning有什麼區別

舉個例子，假設今天老闆給你一個新的數據集，讓你做一下圖片分類，這個數據集是關於Flowers的。問題是，數據集中flower的類別很少，數據集中的數據也不多，你發現從零訓練開始訓練CNN的效果很差，很容易過擬合。怎麼辦呢，於是你想到了使用Transfer Learning，用別人已經訓練好的Imagenet的模型來做。
做的方法有很多：

把Alexnet里卷積層最後一層輸出的特徵拿出來，然後直接用SVM分類。這是Transfer Learning，因為你用到了Alexnet中已經學到了的「知識」。
把Vggnet卷積層最後的輸出拿出來，用貝葉斯分類器分類。思想基本同上。
甚至你可以把Alexnet、Vggnet的輸出拿出來進行組合，自己設計一個分類器分類。這個過程中你不僅用了Alexnet的「知識」，也用了Vggnet的「知識」。
最後，你也可以直接使用fine-tune這種方法，在Alexnet的基礎上，重新加上全連接層，再去訓練網路。

綜上，Transfer Learning關心的問題是：什麼是「知識」以及如何更好地運用之前得到的「知識」。這可以有很多方法和手段。而fine-tune只是其中的一種手段。

Ⅷ altium designer 中怎麼將同一個net全部選中並測量它的長度

您好，您這樣：
1、一般是將走線布完後，新建一個class。 Design -> Classes，加完後可以點擊close。
2、快捷鍵 T + R； 或者 點擊Tools 下拉中的Interactive length tuning 。點擊class中的一條net，然後tab鍵設置屬性。一般選最長的net線做參考。依次設置蛇形走線規則。
3、 T+R點擊class裡面的net逐次調整為蛇形等長線。
4、等長線走線完畢，以上例子緊為參考。
（1）布線時同時按下Ctrl +Shift 並且轉動滑鼠的滾輪， 就可以換層。
（亦可用小鍵盤「*」號鍵來換層）。
（2）布線時按「shift + 空格」來改變線的拐角方式。按「shift + A」畫蛇形線。
（3）布蛇行線的快捷鍵控制：
在布蛇行線時，按快捷鍵「 1 」 「 2 」 「 3 」 「 4 」 「，」 「。」
可以在走線時隨時控制蛇行線的形狀。
快捷鍵 : 1 與 2 ，改變蛇行線的拐角與弧度。
快捷鍵 : 3 與 4 改變蛇行線的寬度。
快捷鍵： ， 與 。改變蛇行線的幅度。
Altium designer如何查看一個net總長度:
方法一：布完線後，按 R ，L 輸出報告，查看網路是否是等長的。
方法二：1、在軟體界面的右下角有一個「pcb」按鈕，點擊此按鈕會彈出下拉菜單，選擇PCB，
此時會彈出「PCB」面板。
2、在彈出的面板中，考上放有一個下拉菜單，選擇「NETS"。
3、選擇需要查看net既可。

Ⅹ .NET平台下幾種SOCKET模型的簡要性能供參考

1.Socket + Threads/ThreadPool大概性能：小於1500個連接 實現：Accept一個Socket，就交給一個線程去管理，比較笨，但也比較有效，因為是同步方式，控制起來很方便。高級點的，就是交給一個線程池去管理，線程池由系統自動託管，省去了開銷線程的時間。一般小型項目，用這個完全足夠，開發也簡單。但要注意，如果若干Socket長時間佔用線程池中的線程，同時其它連接數又比較多，很容易出現提示說你沒有足夠的線程供使用。呵呵，讓Socket少做點事，少佔用時間，換一個快點的CPU是不錯的方式。另外，如果有一些比較好的第三方線程池組件，也可以選擇使用，比如SmartThreadPool。2.Socket + Select大概性能：大於1500個連接後性能下降 實現：Select是很常用的一種模型。是在阻塞功能中輪詢一個或多個Socket，將要處理的Socket放到一個IList中，當Select輪詢結束後，然後我們再自己處理這個IList中的Socket。具體的用法可以看一下MSDN。Select的效率並不能說是高的，因為當隊列中待處理的Socket比較多的時候，處理最後幾個Socket相當於要遍歷所有前面的Socket，非常不劃算的.3.Socket + Asynchronous大概性能：約7500個客戶端連接 實現：BeginXXXX，EndXXXX，再熟悉不過了吧。非同步Socket歸根到底，還是用的線程池技術，用線程池來處理非同步IO。這就又引出個問題，.NET的線程池又是用的什麼實現方式，以前看過有人說，.NET的線程池是用的完成埠來實現的，我不知道這樣的說法是不是正確，從查到的資料中也沒有辦法確認（希望這點有朋友可以告訴我）。非同步Socket對於程序的處理流程來說比同步復雜了許多，非同步回調函數的控制不如同步方式那樣直觀。但有一點我想應該是要注意的，就是回調函數應該輕裝上陣，不應該處理過多的事務，對傳遞數據的處理，應該交給其它線程進行處理。 4.IOCP（完成埠）大概性能：約20000~50000個客戶端連接 實現：現在.NET下有一些偽IOCP，大家可以去搜索一下，還沒有見過開放出來的用這些偽IOCP來實現的SOCKET例子。我說的20000~50000個客戶端連接，是指在C++下開發的情況，這樣的情況下，需要用到的基本技術還包括內存池、查詢演算法等。偽IOCP能實現多少最大連接，沒有資料可以查，如果有朋友知道，可以討論一下。另外上 面提到的許多數據，是從一些資料上摘抄下來的，我沒有自己試過，僅僅是拿出來和大家討論一下。1. Introction - Native Win32 IOCPI/O Completion Ports (IOCP) supported on Microsoft Windows platforms has two facets. It first allows I/O handles like file handles, socket handles, etc., to be associated with a completion port. Any async I/O completion event related to the I/O handle associated with the IOCP will get queued onto this completion port. This allows threads to wait on the IOCP for any completion events. The second facet is that we can create a I/O completion port that is not associated with any I/O handle. In this case, the IOCP is purely used as a mechanism for efficiently providing a thread-safe waitable queue technique. This technique is interesting and efficient. Using this technique, a pool of a few threads can achieve good scalability and performance for an application. Here is a small example. For instance, if you are implementing a HTTP server application, then you need to do the following mundane tasks apart from the protocol implementation:Create a client connection listen socket. Once we get the client connection, use the client socket to communicate with the client to and fro. You can implement it by creating one dedicated thread per client connection that can continuously communicate with the client to and fro. But this technique quickly becomes a tremendous overhead on the system, and will rece the performance of the system as the number of simultaneous active client connections increase. This is because, threads are costly resources, and thread switching is the major performance bottle neck especially when there are more number of threads.The best way to solve this is to use an IOCP with a pool of threads that can work with multiple client connections simultaneously. This can be achieved using some simple steps...Create a client connection listen socket. Once we get the client connection, post an IOCP read message on the socket to an IOCP. One of the threads waiting for completion events on this IOCP will receive the first read message for the client. It immediately posts another read onto the same IOCP and continues processing the read message it got. Once processing the read message is completed, it again waits on the IOCP for another event. This technique will allow a small pool of threads to efficiently handle communication with hundreds of client connections simultaneously. Moreover, this is a proven technique for developing scalable server side applications on Windows platforms.The above is a simplified description of using IOCP in multithreaded systems. There are some good in-depth articles on this topic in CodeProject and the Internet. Do a bit of Googling on words like IO Completion Ports, IOCP, etc., and you will be able to find good articles.2. Introction - Managed IOCPManaged IOCP is a small .NET class library that provides the second facet of Native Win32 IOCP. This class library can be used both by C# and VB.NET applications. I chose the name Managed IOCP to keep the readers more close to the techniques they are used to with native Win32 IOCP. As the name highlights, Managed IOCP is implemented using pure .NET managed classes and pure .NET synchronization primitives. At its core, it provides a thread-safe object queuing and waitable object receive mechanism. Apart from that, it provides a lot more features. Here is what it does:Multiple Managed IOCP instances per process. Registration of multiple threads per Managed IOCP instance. Dispatching System.Object types to a threadsafe queue maintained by each Managed IOCP instance. Waitable multi-thread safe retrieval of objects from the Managed IOCP instance queue by all the threads registered for that particular Managed IOCP instance. Ability to restrict the number of concurrent active threads processing the queued objects related to a particular Managed IOCP instance. Policy based replaceable/customizable approach for choosing a registered thread to process the next available queued object. Ability to pause the Managed IOCP processing. Internally, pauses processing of queued objects by registered threads. Also, by default, disallows enqueuing new objects (can be changed). Run the Managed IOCP instance. Internally re-starts the processing of queued objects by registered threads. Also allows enqueuing new objects (if it is disallowed previously). Modify the max. allowed concurrent threads at runtime. Provides easy accessibility to Managed IOCP instance runtime properties like... Number of active concurrent threads. Number of objects left in queue. Number of allowed concurrent threads. Running status. Safe and controlled closing of a Managed IOCP instance. 2.1. Managed IOCP in Job/Task Oriented Business ProcessesManaged IOCP can be used in other scenarios apart from the sample that I mentioned in the introction to native Win32 IOCP. It can be used in process oriented server side business applications. For instance, if you have a business process ( _not_ a Win32 process) with a sequence of tasks that will be executed by several clients, you will have to execute several instances of the business process, one for each client in parallel. As mentioned in my introction to native Win32 IOCP, you can achieve this by spawning one dedicated thread per business process instance. But the system will quickly run out of resources, and the system/application performance will come down as more instances are created. Using Managed IOCP, you can achieve the same sequential execution of multiple business process instances, but with fewer threads. This can be done by dispatching each task in a business process instance as an object to Managed IOCP. It will be picked up by one of the waiting threads and will be executed. After completing the execution, the thread will dispatch the next task in the business process instance to the same Managed IOCP, which will be picked up by another waiting thread. This is a continuous cycle. The advantage is that you will be able to achieve the sequential execution goal of a business process, as only one waiting thread can receive a dispatched object, and at the same time keep the system resource utilization to required levels. Also, the system and business process execution performance will increase as there are few threads executing multiple parallel business processes.3. Using Managed IOCP in .NET applicationsMultithreaded systems are complex in the context that most problems will show up in real time proction scenarios. To limit the possibility of such surprises while using Managed IOCP, I created a test application using which several aspects of the Managed IOCP library can be tested. Nevertheless, I look forward for any suggestions/corrections/inputs to improve this library and its demo application.Before getting into the demo application, below is the sequence of steps that an application would typically perform while using the Managed IOCP library:Create an instance of the ManagedIOCP class: 2. using Sonic.Net;ManagedIOCP mIOCP = new ManagedIOCP();The ManagedIOCP constructor takes one argument, concurrentThreads. This is an integer that specifies how many maximum concurrent active threads are allowed to process objects queued onto this instance of ManagedIOCP. I used a no argument constructor, which defaults to a maximum of one concurrent active thread.From a thread that needs to wait on objects queued onto the ManagedIOCP instance, call the Register() method on the ManagedIOCP instance. This will return an instance of the IOCPHandle class. This is like native Win32 IOCP handle, using which the registered thread can wait on the arrival of objects onto the ManagedIOCP instance. This thread can use the Wait() method on the IOCPHandle object. The Wait() will indefinitely wait until it grabs an object queued onto the ManagedIOCP instance to which the calling thread is registered. It either comes out with an object, or an exception in case the ManagedIOCP instance is stopped (we will cover this later). 4. IOCPHandle hIOCP = mIOCP.Register();5. while(true)6. {7. try8. {9. object obj = hIOCP.Wait();10. // Process the object11. 12. }13. catch(ManagedIOCPException e)14. {15. break;16. }17. catch(Exception e)18. {19. break;20. }}Any thread (one that is registered with the ManagedIOCP instance and any non-registered thread) that has access to the ManagedIOCP instance can dispatch (Enqueue) objects to it. These objects are picked up by waiting threads that are registered with the ManagedIOCP instance onto which objects are being dispatched. 22. string str = "Test string";mIOCP.Dispatch(str);When a thread decides not to wait for objects any more, it should un-register with the ManagedIOCP instance. mIOCP.UnRegister();Once the application is done with an instance of ManagedIOCP, it should call the Close() method on it. This will release any threads waiting on this instance of ManagedIOCP, clears internal resources, and resets the internal data members, thus providing a controlled and safe closure of a ManagedIOCP instance. mIOCP.Close();There are certain useful statistics that are exposed as properties in the ManagedIOCP class. You can use them for fine tuning the application ring runtime.// Current number of threads that are // concurrently processing the objects queued // onto this instance of Managed IOCP // (This is readonly property) int activeThreads = mIOCP.ActiveThreads;// Max number of concurrent threads // allowed to process objects queued onto this // instance of Managed IOCP (This is a read/write property) int concurThreads = mIOCP.ConcurrentThreads;// Current count of objects queued onto this Managed IOCP instance. // NOTE: This value may change very quickly // as multiple concurrent threads might // be processing objects from this instance of Managed IOCP queue. // So _do not_ depend on this value // for logical operations. Use this only for // monitoring purpose (Status reporting, etc.) // and ring cleanup processes // (like not exiting main thread untill the queued object becomes 0, // i.e. no more objects to be processed, etc) // (This is readonly property) int qCount = mIOCP.QueuedObjectCount;// Number of threads that are registered with this instance of Managed IOCP // (This is readonly property) int regThreadCount = mIOCP.RegisteredThreads;3.1. Advanced usageFollowing are the advanced features of Managed IOCP that need to be used carefully.Managed IOCP execution can be paused at runtime. When a Managed IOCP instance is paused, all the threads registered with this instance of Managed IOCP will stop processing the queued objects. Also, if the 'EnqueueOnPause' property of the ManagedIOCP instance is false (by default, it is false), then no thread will be able to dispatch new objects onto the Managed IOCP instance queue. Calling Dispatch on the ManagedIOCP instance will throw an exception in the Pause state. If the 'EnqueueOnPause' property is set to true, then threads can dispatch objects onto the queue, but you need to be careful while setting this property to true, as this will increase the number of pending objects in the queue, thus occupying more memory. Also, when the Managed IOCP instance is re-started, all the registered threads will suddenly start processing a huge number of objects thus creating greater hikes in the system resource utilization.mIOCP.Pause();Once paused, the ManagedIOCP instance can be re-started using the Run method.mIOCP.Run();The running status of the Managed IOCP instance can be obtained using the IsRunning property:bool bIsRunning = mIOCP.IsRunning;You can retrieve the System.Threading.Thread object of the thread associated with the IOCPHandle instance, from its property named 'OwningThread'.3.2. Demo ApplicationI provided two demo applications with similar logic. The first is implemented using Managed IOCP, the other using native Win32 IOCP. These two demo applications perform the following steps:Create a global static ManagedIOCP instance or native Win32 IOCP. Create five threads. Each thread will dispatch one integer value at a time to the ManagedIOCP instance or native Win32 IOCP until the specified number of objects are completed. Start (creates a new set of five threads) and stop (closes the running threads) the object processing. The Sonic.Net (ManagedIOCP) demo application additionally demonstrates the following features of Managed IOCP that are unavailable in the Win32 IOCP:Pause and continue object processing ring runtime. Change concurrent threads at runtime. Statistics like, Active Threads, Maximum Concurrent threads, Queued Objects Count and Running Status of Managed IOCP. Below is the image showing both the demo applications after their first cycle of object processing:Demo application resultsAs you can see in the above figure, Managed IOCP gives the same speed (slightly even better) as native Win32 IOCP. The goal of these two demo applications is _not_ to compare the speed or features of Win32 IOCP with that of Managed IOCP, but rather to highlight that Managed IOCP provides all the advantages of native Win32 IOCP (with additional features) but in a purely managed environment.I tested these two demo applications on a single processor CPU and a al processor CPU. The results are almost similar, in the sense the Managed IOCP is performing as good as (sometimes performing better than) native Win32 IOCP.3.3. Source and demo application filesBelow are the details of the files included in the article's Zip file:Sonic.Net (folder) - I named this class library as Sonic.Net (Sonic stands for speed). The namespace is also specified as Sonic.Net. All the classes that I described in this article are defined within this namespace. The folder hierarchy is described below: 2. Sonic.Net3. |4. --> Assemblies5. |6. --> Solution Files7. |8. --> Sonic.Net9. |10. --> Sonic.Net Console Demo 11. |--> Sonic.Net Demo ApplicationThe Assemblies folder contains the Sonic.Net.dll (contains the ObjectPool, Queue, ManagedIOCP, IOCPHandle, and ThreadPool classes), Sonic.Net Demo Application.exe (demo application showing the usage of ManagedIOCP and IOCPHandle classes), and Sonic.Net Console Demo.exe (console demo application showing the usage of ThreadPool and ObjectPool classes).The Solution Files folder contains the VS.NET 2003 solution file for the Sonic.Net assembly project, Sonic.Net demo application WinForms project, and Sonic.Net console demo project.The Sonic.Net folder contains the Sonic.Net assembly source code.The Sonic.Net Console Demo folder contains the Sonic.Net console demo application source code. This demo shows the usage of the Managed IOCP ThreadPool, which is explained in my Managed I/O Completion Ports - Part 2 article. This demo uses a file that will be read by the ThreadPool threads. Please change the file path to a valid one on your system. The code below shows the portion in the code to change. This code is in the ManagedIOCPConsoleDemo.cs file.public static void ReadData(){ StreamReader sr = File.OpenText(@"C:\aditya\downloads\lgslides.pdf"); string st = sr.ReadToEnd(); st = null; sr.Close(); Thread.Sleep(100);}The Sonic.Net Demo Application folder contains the Sonic.Net demo application source code.Win32IOCPDemo (folder) - This folder contains the WinForms based demo application for demonstrating Win32 IOCP usage using PInvoke. When compiled, the Win32IOCPDemo.exe will be created in the Win32IOCPDemo\bin\debug or Win32IOCPDemo\bin\Release folder based on the current build configuration you selected. The default build configuration is set to Release mode. 4. Inside Managed IOCPThis section discusses the how and why part of the core logic that is used to implement Managed IOCP.4.1. Waiting and retrieving objects in Managed IOCPManaged IOCP provides a thread safe object dispatch and retrieval mechanism. This could have been achieved by a simple synchronized queue. But with synchronized queue, when a thread (thread-A) dispatches (enqueues) an object onto the queue, for another thread (thread-B) to retrieve that object, it has to continuously monitor the queue. This technique is inefficient as thread-B will be continuously monitoring the queue for arrival of objects, irrespective of whether the objects are present in the queue. This leads to heavy CPU utilization and thread switching in the application when multiple threads are monitoring the same queue, thus degrading the performance of the system.Managed IOCP deals with this situation by attaching an auto reset event to each thread that wants to monitor the queue for objects and retrieve them. This is why any thread that wants to wait on a Managed IOCP queue and retrieve objects from it has to register with the Managed IOCP instance using its 'Register' method. The registered threads wait for the object arrival and retrieve them using the 'Wait' method of the IOCPHandle instance. The IOCPHandle instance contains an AutResetEvent that will be set by the Managed IOCP instance when any thread dispatches an object onto its queue. There is an interesting problem in this technique. Let us say that there are three threads, thread-A dispatching the objects, and thread-B and thread-C waiting on object arrival and retrieving them. Now, say if thread-A dispatches 10 objects in its slice of CPU time. Managed IOCP will set the AutoResetEvent of thread-B and thread-C, thus informing them of the new object arrival. Since it is an event, it does not have an indication of how many times it has been set. So if thread-B and thread-C just wake up on the event set and retrieve one object each from the queue and again waits on the event, there would be 8 more objects left over in the queue unattended. Also, this mechanism would waste the CPU slice given to thread-B and thread-C as they are trying to go into waiting mode after processing a single object from the Managed IOCP queue.So in Managed IOCP, when thread-B and thread-C call the 'Wait' method on their respective IOCPHandle instances, the method first tries to retrieve an object from the Managed IOCP instance queue before waiting on its event. If it was able to successfully retrieve the object, it does
