如果你说的是set的cardinality，那么cardinality就是集合中元素的个数。那么，你可能会问：直接叫count不...
cardinality denotes the number of individual values of a metric. For instance, if an application has two HTTP methods, GET and POST, its cardinality is 2. This concept is crucial in modern monitoring systems due to the vast amount of operational data generated, requiring systems that can man...
Order types and cardinal numbers resulted from successive abstraction, from a set M to its order type M¯ and then to its cardinality M¯¯. Almost two decades after his [1874] result that the reals are uncountable, Cantor in a short note [1891] subsumed it via his celebrated ...
The different types of sets are empty, finite set, singleton set, equivalent set, subset, universal set, superset, power and infinite set. In this particular article, we focused on power sets. Now that we know the definition and how to calculate the power set, its various properties. It’...
In SQL, the term cardinality refers to the uniqueness of data values contained in a particular column (attribute) of a database table. When dealing with columnar value sets, there are 3 types of cardinality: high-cardinality, normal-cardinality, and low-cardinality. ...
//! The metric type is part of its signature just like the unit. Therefore, it is allowed to reuse a //! metric name for multiple metric types, which will result in multiple metrics being recorded. //! //! # Metric Envelopes //! //! To send one or more metrics to Relay,...

Logical expressions, such as 1=1 and 1>2 AND 3>4, that contain only constants. Built-in functions that are considered foldable by SQL Server, including CAST and CONVERT. Generally, an intrinsic function is foldable if it is a function of its inputs only and not other contextual information...

In this article, we will go through 4 popular methods to encode categorical variables with high cardinality: (1) Target encoding, (2) Count encoding, (3) Feature hashing and (4) Embedding. We will explain how each method works, discuss its pros and cons and observe its impact on the per...
