A U-Matrix is a matrix with the same shape as the source data. The value in cell [i,j] of the U-Matrix is the average distance of source data cell [i,j] with its four neighbors (above, below, left, right). In my demo, the visualization of the U-Matrix shows more or less randomness, as you’d expect because the source data is random.

A U-matrix is a visual representation of the distances between neurons in the input data dimension space. Namely you calculate the distance between adjacent neurons, using their trained vector. If your input dimension was 4, then each neuron in the trained map also corresponds to a 4-dimensional vector. Let's say you have a 3x3 hexagonal map.

The U-Matrix is a canonical tool for the display of distance structures in data space using emergent SOM (ESOM).

A U-matrix is defined as a visual representation of the distances between neurons in the input data dimension space. You can calculate the distance between adjacent neurons, using their trained vector. In your case, the input dimension was 4, then each neuron in the trained map also corresponds to a 4-dimensional vector.

In mathematics, a matrix (plural matrices) is a rectangular array or table of numbers, symbols, or expressions, arranged in rows and columns. For example, the dimension of the matrix below is 2 × 3 (read "two by three"), because there are two rows and three columns: The u-matrix is a 9x1 vector: u (1) u (1,2) u (2) u (2,3) u (3) u (3,4) u (4) u (4,5) u (5) where u (i,j) is the distance between map units m (i) and m (j) and u (k) is the mean (or minimum, maximum or median) of the surrounding values, e.g. u (3) = (u (2,3) + u (3,4))/2. 优智方 (U Matrix) 精准模式经过精心选择和巧妙安排的测试，能够最大程度的评价您当前的学习水平。. 为了如实反映你的当前学情，请认真完成评测内容，避免猜答案的情况。. 为此，我们在选择题的选项里多了一个“我不会”选项。.
