ABSTRACT

Based on the variant measurement model, this paper uses the combined transformation method to convert the binomial coefficients into a polynomial combination counting formula which contains quaternary variables. The two-dimensional quantitative counting matrix is obtained by using the combination function calculation method. Then the related numerical calculation results are converted into statistical histograms and project them on the coordinate axes. The visualization of the final polynomial combination formula is presented in a two-dimensional color map mode. It can be seen from the variant maps of the polynomial that the graphical results under multiple conditions exhibit spatial symmetry, as well as special changes and fixed characteristics of the points.

1. Introduction

Algorithmic study is the core issue in artificial intelligence, machine learning, and big data. The research and optimization of various algorithms relies on a solid mathematical foundation. The combination function [1] [2] occupies an important branch in mathematics. It plays an important role in mathematics field such as elementary number theory, graph theory, statistics and probability. It is more and more important to study the mechanism of combination counting from the perspective of basic mathematics. Traditional combinatorial counting study focuses on the proof of identity, and the visualization of polynomial combinations needs to be further explored. From the perspective of probability and statistical distribution, visualization is a research tool that is as important as experiments, theory, and calculations. It can geometrically solve complex problems and abstract problems. Showing mathematical formula as a graphical allows probabilistic researchers to make global observations and find unique features.

The calculation of combined counts has always played a central role in data description and analysis in the direction of probability and statistical distribution. In order to describe the distribution characteristics of polynomial combination anomaly, this paper which bases on variant measurement theoretical model and binomial coefficient realizes the visual exploration of polynomial combination distribution by a calculation model containing with choosing polynomial combination expression, calculating combination formula and matrix projection. The 2D spatial distribution matrix is obtained by the combination calculation method. Then the spatial distribution matrix is drawn to obtain a two-dimensional histogram, and finally the histogram is projected on the coordinate axis and presented in a color map mode. From a global perspective, this paper explores the variation and invariant characteristics of polynomial combinations, and the clustering distribution characteristics of various combined transforms are studied.

2. Elementary Formula

2.1. Vandermonde’s Convolution

Vandermonde’s convolution [3] [4] is a binomial coefficient formula consisting of summing over a product of two related binomial coefficient.

Definition: for integer n, the basic identity

k ( r k ) ( s n k ) = ( r + s n ) (1)

2.2. Core Formula

Please refer to [5] for variant measurement, and the core formula details are in Part Two on page 58-68.

According to the variant theory, the binomial coefficient formula needs for a simple processing containing m and p for equivalent replacement. In combination with Equation (1), there is

( m p ) = k = 0 p ( m 2 q p k ) ( 2 q k ) (2)

In Equation (2), m is the total, p is the number of 1 element, q is the number of 0 - 1 elements and k is the coincidence number. The ranges of each variable respectively is: 0 q / 2 m , 0 p m , 0 k p .

3. Calculation Model

By using the correlation formula of variant measurement, the processing model of the combination number of solutions required in this paper is as follows (Figure 1).

Figure 1. Solution processing model.

Choose core formula: Based on the binomial coefficients and variant measurement, select the core formula. It means that replace two variables (m, p) with four variables (m, p, q, k). The new polynomial combination expression is:

k = 0 p ( m 2 q p k ) ( 2 q k ) .

Calculation: Take m as an arbitrary integer, control any one variables (p, k, q), and calculate the polynomial combination formula by using the combination number calculation method.

Counting matrix: It is the result distribution matrix.

2D map: Project the counting matrix onto a two-dimensional planar graph to form a thermal diagram composed of points.

4. Result

4.1. Counting Matrix

For formula k = 0 p ( m 2 q p k ) ( 2 q k ) , we take m = 12, m = 13, control the value of p as an example. The counting matrix results of combination formula are as follow Tables 1-3.

4.2. 2D Map

4.2.1. m = 12

Project the space of the two-dimensional counting matrix, with k, q as the horizontal and vertical coordinates. Map the distribution matrix on the plane and form a plurality of thermodynamic diagram composed of squares. The results of combination expression contain 12 figures, and this paper selects 6 figures to analyze.

The following figure (Figure 2) is the result graphic that the variable p takes different values (p = 1, p = 3, p = 6, p = 8, p = 11, p = 12) when m takes 12.

4.2.2. m = 13

In order to facilitate the comparative analysis and description, this paper also gives the results of the p-value transformation when variable m takes 13 (Figure 3).

The value of the p is: p = 1, p = 3, p = 6, p = 9, p = 12, p = 13.

5. Result Analysis

According to the transformation of the p value, Figure 1 and Figure 2 are graphical representations of the results obtained by taking m = 12, m = 13. The same points and different points in the two sets of figures can be easily observed.

The same points: From the shape of the graph, with the transformation of p,

Table 2. The result of counting matrix (p = 6).

Figure 2. Figure for m = 12.

Figure 3. Figure for m = 13.

the graph formed by the counting distribution matrix is a graph with some special rules. When the values of m and q are the same, a linear graph composed of squares is formed. In Figure 1, p = 1, p = 3, p = 6 is roughly similar to the shape of the graph formed by p = 1, p = 3, p = 6 in Figure 2. When p = 8, p = 11, p = 12 in Figure 1, it is similar to the shape of the graph formed by p = 9, p = 12, p = 13 in Figure 2. When m is different, p is same, there is always a point of the same color, located at the top left of the graph square.

The different points: From the 6 result graphs in Figure 1, each two-dimensional map is symmetrical and the polynomial combination expression has two maximum values, which respectively are located in the upper left and lower right of the figure. The pictures in Figure 2 are not symmetrical, and there is only one maximum value, located in the upper left of the figure.

From the whole perspective, the counting formula can be transformed into different graphs, and each of the obtained two-dimensional graphs has its own characteristics. When m is even, the projected graph exhibits symmetrical characteristics. When m is taking an odd number, the projected figure does not show symmetry. These two situations reflect the characteristics of the variant. Conversely, multiple graphs are derived from the same polynomial combination expression, which explains the equivalence invariance in the variant construction.

6. Conclusion

In this paper, the binomial coefficient formula is processed to form multiple variant maps by utilizing the variant measurement model while distribution matrix is analyzed and explored from the perspective of visualization. The basic processing method consists of four core modules: selecting multiple combination formulas, calculations, counting matrices, and 2D variant maps. It can be seen from the point distribution in the figure that the new combination counting formula exhibits an unusually rich feature in the counting matrix distribution, and graphs and the point transformation all exhibit unique properties by controlling the values of the variables m and p. This variant visualization method has not only produced good results in processing the binomial coefficients, but also provided new ideas for the research of basic mathematics, combinatorial mathematics, probability and statistical distribution, etc. This method has extremely far-reaching significance.
