  2. Joint entropy - Wikipedia

    en.wikipedia.org/wiki/Joint_entropy

    A misleading [1] Venn diagram showing additive, and subtractive relationships between various information measures associated with correlated variables X and Y. The area contained by both circles is the joint entropy H(X,Y). The circle on the left (red and violet) is the individual entropy H(X), with the red being the conditional entropy H(X|Y ...

  3. Temperature–entropy diagram - Wikipedia

    en.wikipedia.org/wiki/Temperature–entropy_diagram

    In thermodynamics, a temperature–entropy (T–s) diagram is a thermodynamic diagram used to visualize changes to temperature (T ) and specific entropy (s) during a thermodynamic process or cycle as the graph of a curve. It is a useful and common tool, particularly because it helps to visualize the heat transfer during a process.

    The violet is the mutual information ⁠ (;) ⁠. Venn diagram of information theoretic measures for three variables x, y , and z . Each circle represents an individual entropy : ⁠ H ( x ) {\displaystyle H(x)} ⁠ is the lower left circle, ⁠ H ( y ) {\displaystyle H(y)} ⁠ the lower right, and ⁠ H ( z ) {\displaystyle H(z)} ⁠ is the ...

    English: This diagram shows the relation between the entropies of two random variables X and Y and their mutual information, joint entropy and relative (conditional) entropies. Deutsch: Dieses Diagramm visualisiert die Beziehung zwischen den Entropien zweier Zufallsvariablen X und Y und ihrer gemeinsamen Information, Verbundentropie und ...

  6. Conditional entropy - Wikipedia

    en.wikipedia.org/wiki/Conditional_entropy

    In information theory, the conditional entropy quantifies the amount of information needed to describe the outcome of a random variable given that the value of another random variable is known. Here, information is measured in shannons , nats , or hartleys .

  7. Mutual information - Wikipedia

    en.wikipedia.org/wiki/Mutual_information

    The circle on the right (blue and violet) is (), with the blue being (). The violet is the mutual information I ⁡ ( X ; Y ) {\displaystyle \operatorname {I} (X;Y)} . In probability theory and information theory , the mutual information ( MI ) of two random variables is a measure of the mutual dependence between the two variables.

  8. Thermodynamic diagrams - Wikipedia

    en.wikipedia.org/wiki/Thermodynamic_diagrams

    Thermodynamic diagrams are diagrams used to represent the thermodynamic states of a material (typically fluid) and the consequences of manipulating this material. For instance, a temperature– entropy diagram ( T–s diagram ) may be used to demonstrate the behavior of a fluid as it is changed by a compressor.

    Fig.2 Temperature–entropy diagram of nitrogen. The red curve at the left is the melting curve. The red dome represents the two-phase region with the low-entropy side the saturated liquid and the high-entropy side the saturated gas. The black curves give the TS relation along isobars. The pressures are indicated in bar.
