Mathematical Notations
Notation  |  
       Definition  |  
      
|---|---|
n or m  |  
       The number of observations in a tabular dataset. Typically n is used, but sometimes m is required to distinguish two datasets, e.g., the training set and the inference set.  |  
      
p or r  |  
       The number of features in a tabular dataset. Typically p is used, but sometimes r is required to distinguish two datasets.  |  
      
  |  
       The dimensionality of a matrix (dataset) has a rows (observations) and b columns (features).  |  
      
V  |  
       The vertex set in a graph.  |  
      
E  |  
       The edge set in a graph.  |  
      
u, v or w  |  
       The vertex in a graph.  |  
      
  |  
       The edge in a graph.  |  
      
  |  
       Depending on the context may be interpreted as follows: 
  |  
      
  |  
       The    
         |  
      
  |  
       Sign function for    
         |  
      
  |  
       In the description of an algorithm, this typically denotes the i-th feature vector in the training set.  |  
      
  |  
       In the description of an algorithm, this typically denotes the i-th feature vector in the inference set.  |  
      
  |  
       In the description of an algorithm, this typically denotes the i-th response in the training set.  |  
      
  |  
       In the description of an algorithm, this typically denotes the i-th response that needs to be predicted by the inference algorithm given the feature vector   |
