the entire data. Therefore, we need to use the principal component analysis of the processing method. 3. Data Dimension Reduction To illustrate what is the main component of the data, start with the data dimensionality reduction. Data dimensionality reduction is going on. Assuming that there are a series of points in the three-dimensional space, which are distributed over the slope of an over-origin point, if you use the natural coordinate system x, Y, z these three axes to represent this set o

The first thing to understand about the numerical Python package is that numerical python will not let you do any work that standard Python cannot do. It just allows you to do the same tasks that standard Python can accomplish with much faster speed. More than that, many array operations are much more elegant to express in Numeric or Numarray than by using standard Python data types and syntax. However, the astonishing speed is the main reason to attract users to use numerical Python. In fact,

"container defaults to exist two axes: 水平的主轴(main axis) and 垂直的交叉轴(cross axis) , the beginning of the main axis (and the intersection of the border) is called main start, the end of the position is called main; The start position of the cross axis is called Cross start, and the end position is called the cross ending. The project is arranged by default along the main axis, the main axis space occupied by a single item is called main size, and the cross axis space occupied is called Cross size "

information table, X indicates that the dimensions of the high dimensional input matrix are the high dimension D times the number of samples N, C=xxt, Z represents the dimension reduction output matrix size low dimension d times N, E=zzt, the linear mapping is Z=WTX, the distance matrix between 22 in the high-dimensional space is a, and the SW,SB is LDA respectively. In-class divergence matrices and inter-class divergence matrices, K indicates that a

~ There are three samples: A (18), B (19), C (18 ). Then the Min's distance between A and B (whether it is the distance from Manhattan, Euclidean distance, or chibbihov) is equal to the Min's distance between A and C, but is 10cm in height really equivalent to 10kg in weight? Therefore, it is very difficult to use Min's distance to measure the similarity between these samples. To put it simply, there are two main disadvantages of Min's distance: (1) view the

An important difference between multidimensional data and two-dimensional data in common relational databases is that there are some additional Dimension, that is, adding more conditions to data display. Therefore, the dimension concept in a multi-dimensional dataset is It is very important that we have recently reached the Data Warehouse. It may be said that the data mart is more specific, that is, some During initial creation of multi-dimensional data, the selection of

"Scope" is, that is, what to learn and what the goal is, in addition, the Internet has caused information flooding and ample knowledge. The biggest problem for most people who are "Fed" by education is "I love to learn, but if you do not know what to learn, you will not learn anything. "A few people will learn everything. As a result, many" very good learning "children will not learn. In addition, in the current Chinese environment, achievements and excellence are often not due to the knowledge

analytical processing): Online Analytical Processing OLAP was proposed by E. F. codd in 1993.Definition by the OLAP Council: OLAP is a software technology that enables analysts to quickly, consistently, and interactively observe information from various aspects to gain an in-depth understanding of data, this information is directly converted from raw data. They reflect the real situation of the enterprise in a way that is easy to understand.Most of OLAP policies store relational or common data

demand is relatively stable, but this is often not the case. We can have more models such as t80, T90, and t100, in addition, the platform may not only support mobile phones and PCs, but also PSP and handheld computers. When there is such a two-way demand change, if the above design will bring a lot of problems, there will be more repeated code, and the structure between classes will become very complex, adding a new platform and several models will be troublesome. For example: Motivation Think

so on.Multidimensional Data Model: Cube: Each subset of a given dimension generates a cuboid (called a cube ). In this way, the data can be displayed at the aggregation level or group by at different granularities, And the content above the entire body becomes cube. The cube summarized at the lowest layer is called the basecuboid ). After a summary of a dimension appears, it is not a basic cube. The data aggregated to the highest level is called the vertex cube (apexcuboid), for example, 0-D cu

, Euclidean distance, or chibbihov) is equal to the Min's distance between A and C, but is 10cm in height really equivalent to 10kg in weight? Therefore, it is very difficult to use Min's distance to measure the similarity between these samples. To put it simply, there are two main disadvantages of Min's distance: (1) view the dimensions of each component, that is, the unit. (2) The distribution of each component (expectation, variance, etc.) may be d

I. Question proposal When you use MDX to query a multi-dimensional dataset, you often encounter this situation. The row or column axis contains multiple dimensions (CrossJoin), and CellSet returns the values of multiple dimension members, when converting CellSet to DataTable, we hope to return the values of these dimension members. However, the method found on the Internet, as described in the previous "FusionChart data presentation case for MDX query
