Is it preferable to symmetrize A prior to the similarity transformation, or to symmetrize B after the similarity transformation...? I'm not familiar with any theorems that relate the real part of a matrix's eig

The class similarities.MatrixSimilarity is only appropriate when the whole set of vectors fits into memory. For example, a corpus of one million documents would require 2GB of RAM in a 256-dimensional LSI space, when used with this class. Without 2GB of free RAM, you would need to use the...
a simple way is to first concatenate them together and then calculate asimilarity matrix. However, it is very difficult to define appropriate weights for different features and also difficult to leverage their complementary and common information. To address this issue, we first computed ...
Data transformation plays a significant role in converting unprocessed data into an understandable form. Data reduction is performed to obtain a reduced representation of the data that is significantly smaller in volume but maintains the original quality. Data preprocessing is an important task while ...
For example, for the ‘hot drinks’ edge in the graph in Fig. 5, the patterns that are similar to it such as ‘hot beverages’ and ‘warm drinks’ are added with the initial transformation using similarity matrix (which correspond to elements in \(\mathbf {M_{1}}\) in Eq. (8)) ...
Example 3 matrix dissimilarity drops observations containing missing values, except when the Gower mea- sure is specified. The computation of the Gower dissimilarity between 2 observations is based on the variables where the 2 observations both have nonmissing values. We illustrate using a dataset ...
[ 14 ], e.g., commonly used log-odds transformation of counts [ 15 ], with resultant matrix elements having any real value. in addition, it seems more intuitive to have a similarity measure directly based on the number of binding sites recognized by both tested tfbs models. here we ...
Any similarity transformation can be represented as the successive application of a homothetic transformation and a proper or improper motion. The concept of similarity and similarity transformations are used in such engineering applications of geometry as modeling and drawing. For example, the operation ...
2) similar transformation matrix 相似变换矩阵 1. A simple method for calculating the power of an ordinary square matrix is given by using the Jordan normal form of matrix and its similar transformation matrix. 利用矩阵的Jordan标准形及其相似变换矩阵进一步给出了一般n阶方阵幂的一种简便求法。
