Mathematical Notations

Notation
Definition
LaTex Math image. or LaTex Math image.
The number of observations in a tabular dataset. Typically LaTex Math image. is used, but sometimes LaTex Math image. is required to distinguish two datasets, e.g., the training set and the inference set.
LaTex Math image. or LaTex Math image.
The number of features in a tabular dataset. Typically LaTex Math image. is used, but sometimes LaTex Math image. is required to distinguish two datasets.
LaTex Math image.
The dimensionality of a matrix (dataset) has LaTex Math image. rows (observations) and LaTex Math image. columns (features).
LaTex Math image.
The vertex set in a graph.
LaTex Math image.
The edge set in a graph.
LaTex Math image., LaTex Math image. or LaTex Math image.
The vertex in a graph.
LaTex Math image.
The edge in a graph.
LaTex Math image.
Depending on the context may be interpreted as follows:
  • If LaTex Math image. is a set, this denotes its cardinality, i.e., the number of elements in the set LaTex Math image..
  • If LaTex Math image. is a real number, this denotes the absolute value of LaTex Math image..

LaTex Math image.
LaTex Math image.
Sign function for LaTex Math image.,
LaTex Math image.
LaTex Math image.
In the description of an algorithm, this typically denotes the LaTex Math image.-th feature vector in the training set.
LaTex Math image.
In the description of an algorithm, this typically denotes the LaTex Math image.-th feature vector in the inference set.
LaTex Math image.
In the description of an algorithm, this typically denotes the LaTex Math image.-th response in the training set.
LaTex Math image.
In the description of an algorithm, this typically denotes the LaTex Math image.-th response that needs to be predicted by the inference algorithm given the feature vector LaTex Math image. from the inference set.
