A strongly typed dataset can help us quickly build the data access layer, and its simplicity allows us to use it extensively in small projects. But it also has some minor flaws, and here is a discussion of what the flaws are and how we can avoid them. 1 in a query, it only supports operations on this table and does not support operations on multiple tables. In this case, we can write a stored procedure ourselves and create a new TableAdapter so that it will help us generate a new logical entity

in machine learning, we often encounter unbalanced datasets. In cancer data sets, for example, the number of cancer samples may be far less than the number of non-cancer samples, and in the bank's credit data set, the number of customers on schedule may be much larger than the number of customers who defaulted. For example, a very well-known German credit data set, the positive and negative sample classification is not very balanced: If you do not do

with SQL statements and stored with a specified name, then to call the database to provide the same functionality as a defined stored procedure, just call execute to automatically complete the commandAdvantages of stored procedures:1. Stored procedures are compiled only at creation time, and each subsequent execution of the stored procedure does not need to be recompiled, while the general SQL statements are compiled once per execution, so the stored procedure is usedCan improve database execut

1. Basic Concepts A DataSet is an off-line cache-storing data that, like a database, has a hierarchy of tables, rows, columns, and also includes constraints and associations between data defined for a dataset. The user can pass. NET Framework's namespace (NameSpace) to create and manipulate datasets. Users can understand the concept of a dataset through the composition of these standards, such as attributes (properties), Collections (collections).

PETS-ICVS datasets Warning:you are strongly advised to view the Smart meeting specification file available This is before any data. This would allow you to determine which part of the "data is" most appropriate for you. The total size of the dataset is 5.9 Gb.

Other articles Http://blog.csdn.net/baolinq The last time I wrote an article about using YOLO to train an VOC dataset, the Portal (http://blog.csdn.net/baolinq/article/details/78724314). But you can't always use just one dataset and use a few datasets to see the results. Because I am mainly in the vehicle and pedestrian detection. Just Kitti data set is a public authoritative data set for unmanned driving, including a large number of roads,

A recent need to move large volumes of datasets to the new storage Class, new volume, is beginning to feel very headache. After careful study, it is very simple to find this thing. It really fits the other person's saying that things are going to be easier after you really start trying. First create your target Storage class and Storage group, and add the relevant volume to the SG, this time do not need to worry about existing vol on a dataset alread

(that is, the last data) Server Dataset I. reasons why a server dataset is requiredWhen using the client dataset, You need to download all the datasets to the client during system logon. If the dataset has a large amount of data, you need to consume a large amount of data during logon. Starting from this, we designed a server-side dataset. Ii. Principles of server-side DatasetsWhen the server starts, the server downloads the required dataset to the s

When using gdal to read data from HDF, netcdf, and other datasets, two steps are generally required: first, to obtain the sub-dataset in the dataset; second, to read the image data from the sub-dataset obtained in the first step. There are many subdatasets in a general HDF image, such as frequently-used modem_data. When you use ENVI to open the image, the following dialog box is displayed to allow users to select the subdataset to be opened (1 ). Fig
