lmr tuning

I believe many of my friends, whether engaged in development, architecture, or DBA, often hear the word "tuning. Speaking of "tuning", it may make many technical staff feel excited, or it may make many people feel distressed. Of course, there are also many people who despise this because not everyone is exposed to a large number of projects, and not everyone does have high performance requirements. In mains

insufficient sample quantity. —————————————————————————————————————————————————————————————————————————————— apply the trained model to the new data set. The main advantage is that the same effect can be achieved in a shorter period of time compared to training from scratch.Example:1.fine-tuning: Start with CNN training on cifar100, then just modify the last layer Softmax the number of output nodes (100 to 10), and then put on the CIFAR10 training.2.

Transferred from: http://blog.csdn.net/u010402786/article/details/70141261Preface What is the fine tuning of the model? Train with someone else's trained network model, if you have to use the same network as someone else, because the parameters are based on the network. Of course the last layer can be modified, because our data may not have 1000 classes, and only a few. Change the name of the output category and layer on the

Trust a lot of friends, whether it is to do development, architecture, or DBA, are often heard that the word "tune". Speaking of "tune", may let a lot of technical staff heart surging, may also make a lot of people feel distressed. Of course, there are a lot of people are dismissive of this, because not everyone has access to the project is very large, and not everyone does the project is very high performance requirements. In the mainstream enterprise-level development and Internet application

DB2 magazine is a quarterly journal dedicated to database administrators, analysts, programmers, designers, consultants, and MIS/DP managers covering all DB2 platforms (including IBM AIX, Hewlett-Packard HP-UX, Sun Solaris, SCO UnixWare, Linux, Microsoft Windows NT, Microsoft Windows 95, Microsoft Windows 98, IBM OS/2, IBM OS/400, IBM MVS, IBM os/390, Various topics for IBM VM and IBM VSE. To get the best performance from DB2 Information Integrator, the DBA needs to know something. Most DBAs k

8.5.1 Index and system performance Indexing speeds up data retrieval, but it slows the insertion, deletion, and updating of data. In particular, the cluster index, the data is stored in a logical order in a certain physical location, when changing data, according to the new data sequence, the need to move a lot of data physical location, which will increase the burden of the system. For non-clustered indexes, the index pages need to be updated when the data is updated, which also takes up the s

About MySQL database, here do not do too much introduction, open source, free and other features favored by various internet industry, especially after some large e-commerce applications, it is highly respected. There was a time in front of me writing a tuning series of SQL Server databases that

Machine learning algorithms are numerous, and various algorithms involve more parameters, this article will briefly introduce the RF,GBDT and other algorithms of tuning experience and steps. 1. BP Tuning matters1.BP is sensitive to feature scaling, first scale data.2. Experience shows that L-bfgs converges faster on small data, and Adam works well on Big data, and SGD adjusts well on the parameter learning

We often see articles boasting about how fast a product is, how strong it is, and how it is better to test than some of the data described. The reason may be that you don't really understand the internal structure, and are not aware of its performance tuning approach. This article transferred from Taobao's Ken Wu classmate's blog, is currently seeing the more complete hbase tuning article. Original link: hb

ObjectiveIn the previous article, we analyzed how the query optimizer works, including: detailed operation steps of the query optimizer, analysis of filter conditions, optimization of index items, and other information.In this article we analyze the detection of several key indicator values in the course of our operation.These indicator values are analyzed to analyze the operation of the statement and to analyze how it is optimized.Through this article we can learn the

In addition to the integrated VISUALVM and Jconsole, the JDK itself provides performance tuning monitoring tools such as JPS, Jstack, Jmap, Jhat, and Jstat.In Java development, we sometimes encounter the following problems:OutOfMemoryError, Low memoryMemory leaksThread deadlockLock contention (lock contention)The Java process consumes too much CPU......These problems may be overlooked by many people in their daily development (for example, some people

Performance Tuning for mysql SQL statements Performance Tuning for mysql SQL statements In server development, there are sometimes requirements on the concurrency, and sometimes an SQL statement, such as a stored procedure, affects the speed. Now, if the execution of an SQL statement is slow during server code execution, how can we optimize it? Performance Tuning
