Includes nearly 400 datasets of different sizes and types for classification, regression, clustering, and referral system tasks. The data set list is located at:http://archive.ics.uci.edu/ml/2.

The database is a machine learning database proposed by the University of California at the University of Virginia (universityofcaliforniairvine). There are currently 187 datasets in this database, and the number of these databases is increasing, UCI dataset is a common standard test dat
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 s
Machine learning algorithms must act on data. The nature of data determines whether the applied machine learning algorithms are suitable, and the quality of data determines the performance of algorithms. Therefore, it is important to study and analyze data. This article, as the first part of the study data series, list
. MapReduce is free to select a node that includes a copy of a shard/block of dataThe input shard is a logical division, and the HDFS data block is the physical division of the input data. When they are consistent, they are highly efficient. In practice, however, there is never a complete agreement that records may cross the bounds of a block of data, and a compute node that processes a particular shard gets a fragment of the record from a block of data Hadoop

Image classification, as the name suggests, is an input image, output to the image content classification of the problem. It is the core of computer vision, which is widely used in practice.
The traditional method of image classification is feature description and detection, such traditional methods may be effective for some simple image classification, but the tradit

. According to common sense, there should be a simple tool, and then gradually improve, but the more powerful LIBSVM was released long before Liblinear. To answer this question, you have to start with machine learning and the history of SVM.

the shortage of security professionals and the need for large datasets to be handled in a secure state, it is not surprising that vulnerability remediation cannot keep up with cyber attackers.
Recent industrial surveys have shown that it takes an average of 146 days for an organization to fix a fatal leak. These findings have undoubtedly sounded a wake-up call for us to rethink the existing enterprise security imperative.
Attackers have long used

Let's look at the example of predicting house price. We will first perform linear regression on the data, that is, the first graph on the left. If we do this, we can obtain such a straight line that fits the data, but in fact this is not a good model. Let's look at the data. Obviously, as the area of the house increases, the changes in the housing price tend to be stable, or the more you move to the right
