## Uses
|
74 |
-
|
75 |
-
This dataset was generated to study ML model's ability yield insight on an open
|
76 |
-
problem in algebraic combinatorics, specifically, the problem of better understanding commutation
|
77 |
-
equivalent representations of reduced words coresponding to the longest permutation.
|
78 |
-
|
79 |
-
### Direct Use
|
80 |
-
|
81 |
-
We use this dataset for a classification task distinguishing between weaving and non-weaving patterns.
|
82 |
-
|
83 |
-
### Out-of-Scope Use
|
84 |
-
|
85 |
-
None.
|
86 |
-
|
87 |
-
## Dataset Structure
|
88 |
-
|
89 |
-
Each matrix is stored on a single line in row-major format (see example above).

-
|
93 |
-
Data generation scripts can be found

-
### Curation Rationale
|
97 |
-
|
98 |
-
This dataset was generated as a test of current AI system's ability to advance
|
99 |
-
research mathematics.
|

#### Who are the source data producers?
|
102 |
-
|
103 |
-
Herman Chau wrote code to generate this dataset.
|
104 |
-
|
105 |
-
## Bias, Risks, and Limitations
|
106 |
-
|
107 |
-
We only provide data for weaving patterns of size \\(6 \times 5\\) and \\(7 \times 6\\) in this repository.
|
108 |
-
We are happy to generate (subsets) of datasets for larger values of \\(n \times n-1\)).
