Algorithm Star-MachineBrain
The AS machine learning library provides a Java API for various machine learning algorithms. It has the encapsulation of complex computing logic such as machine vision and natural language processing. Through the library, various algorithms can be quickly used to achieve various effects. Many calculation operations in the AS library are implemented natively, enabling the operation of library functions without unexpected dependencies from the Java standard library.
There are multiple versions of the AS library directory. If you want to query the update logs and differences of different versions, you can view here.
A test dataset is provided in this warehouse, which contains various data files such as images. You can pull these test data into a local program through a URL for calculation.
You can integrate Arithmetic Star into your project through maven, and the configuration of Maven is shown below. You can add it to your maven project, or you can download it from Releases and manually integrate it into your project.
<dependencies>
<dependency>
<groupId>io.github.BeardedManZhao</groupId>
<artifactId>algorithmStar</artifactId>
<version>1.18</version>
</dependency>
</dependencies>
After version 1.17, all dependencies of the AS library have been stripped to better avoid binding dependencies and reduce the possibility of project conflicts. At the same time, more suitable dependency configuration items can be used according to the needs of developers. You can view third-party library dependencies on which the AS library depends here.
The AS library generates some log data when performing many calculation functions. Therefore, the use of the AS library requires importing log dependencies, which are essential. Please import the dependencies as follows.
<dependencies>
<!-- Binding using the adapter of log4j2 -->
<dependency>
<groupId>org.apache.logging.log4j</groupId>
<artifactId>log4j-slf4j-impl</artifactId>

When interfacing with various platforms such as databases and Sparks, the AS library needs to use third-party dependency packages, which are optional. If you do not need to use these functions, you may not need to import dependencies. If you need to, you can refer to the following configuration.

Feature computing components are often used in feature engineering, and are the main force of computing in machine learning tasks. Measurement algorithms, classification algorithms, etc. can use this component computing method. The feature engineering calculation in Arithmetic Star is component-based calculation. You can directly obtain component objects and call component functions, or use Arithmetic Star's portal class for feature engineering.
Next is a simple example of feature engineering calculation using algorithmic star portal class

public static void main(String[] args) {
// Prepare an array of two texts, including two string statements that need to be processed into feature vectors.
String[] data = {
"Good evening, dear, don't forget the agreement between us. It's 9:00 tomorrow morning.",
"Good morning, dear, don't forget the agreement between us, at 9:00 in the morning."
};
AlgorithmStar<Object, ColumnIntegerMatrix> algorithmStar = AlgorithmStar.getInstance();
// Start feature extraction, and a matrix will be returned after the word frequency vector is successfully extracted
ColumnIntegerMatrix word = algorithmStar.extract(WordFrequency.getInstance("word"), data);
// Print the generated vector matrix
System.out.println(word);
// Start to obtain the vector corresponding to the two sentences in the matrix
int[] arrayByColIndex1 = word.getArrayByColIndex(0);
int[] arrayByRowIndex2 = word.getArrayByColIndex(1);
// Start to calculate the German distance between two vectors
double res = algorithmStar.getTrueDistance(EuclideanMetric.getInstance("e"), arrayByColIndex1, arrayByRowIndex2);
System.out.println(res);

System.out.println(res1);

Here is an example of the use of "ZhaoCoordinateNet2D", which shows the analysis and prediction of the relationship between people. In the "ZhaoCoordinateNet" algorithm, the relationship network of people is analyzed, and at the same time, the network analysis and mapping can be performed.

public class MAIN1 {
public static void main(String[] args) {
// Builder coordinates (2D)
DoubleCoordinateTwo A = new DoubleCoordinateTwo(10, 10);
DoubleCoordinateTwo B = new DoubleCoordinateTwo(-10, 4);
DoubleCoordinateTwo C = new DoubleCoordinateTwo(1, 0);
DoubleCoordinateTwo E = new DoubleCoordinateTwo(6, 1);
DoubleCoordinateTwo Z = new DoubleCoordinateTwo(1, 21);
/*
Get the relationship network. This algorithm is implemented by me to infer the relationship network of people.
You can customize the name here. It should be noted that the instantiation of the integrator below requires you to pass the name in.
*/
ZhaoCoordinateNet2D zhaoCoordinateNet = ZhaoCoordinateNet2D.getInstance("Z");
/*
Add the relationship of people to the relationship network, please note that the relationship network of the algorithm already contains your data,
so you must pass the same name in the integration below, so that the integrator can get the temporary network in your algorithm grid data
*/
zhaoCoordinateNet.addRoute(DoubleConsanguinityRoute2D.parse("A -> B", A, B)); // Representing A takes the initiative to know B
zhaoCoordinateNet.addRoute(DoubleConsanguinityRoute2D.parse("A -> C", A, C));
zhaoCoordinateNet.addRoute(DoubleConsanguinityRoute2D.parse("E -> Z", E, Z));
zhaoCoordinateNet.addRoute(DoubleConsanguinityRoute2D.parse("A -> Z", A, Z));
zhaoCoordinateNet.addRoute(DoubleConsanguinityRoute2D.parse("B -> Z", B, Z));
// Use a 2-dimensional route drawing integrator to output a picture of the relationship network between all the people above
Route2DDrawingIntegrator a = new Route2DDrawingIntegrator("A", "Z");
// Set image output path
a.setImageOutPath("D:\\out\\image.jpg")
// set image width
.setImageWidth(1000)
// set image height
.setImageHeight(1000)
// Set discrete thresholds to amplify small changes
.setDiscreteThreshold(4)
// Run the integrator!
.run();
// Clean data in relational network
zhaoCoordinateNet.clear();
}
}

The directory contains the DLL dynamic library file and the source code corresponding to the library file that the Algorithm Star machine learning library depends on when it runs. In order to achieve better compatibility in the machine learning library, the C compiled DLL is introduced. Users can load the DLL into the machine learning library before the AS library runs.
The knowledge base file archive is used for the storage task of AS-MB series knowledge documents. You can access it directly through the documents on the home page. There is no need to enter here directly. It is messy internally.
The source code storage directory of AS-MB, where you can view the relevant source code of AS-MB. Of course, here is the latest source code, which you can use to compile, so that you can obtain the latest version.
Note: The latest version is often unstable, so we recommend you to use the version that has been released for a long time!
