Die Grafik sowie, abgesehen vom ersten Satz, auch die Beschreibung derselben stammen aus der Quelle. Ein Verweis auf diese fehlt aber. Das hier gewählte Beispiel für den "Chinese Restaurant Process" ist nur eines von vielen denkbaren ähnlichen Beispielen. |

The second customer enters and decides either to sit at the first table with a probability 1/1 + α [or a new table with probability α /1 + α.

Notice that popular tables become less and less likely to sit down at a new table. In this representation the dishes correspond to probability density functions, and the process of ordering a dish l corresponds to drawing the parameters φl to a probability density function, as for example a Gaussian from a prior distribution G over those parameters. The process of a customer l choosing a table cl corresponds to choosing a distribution 㱬l from which to draw an observation yl. Since the structure of the process, is that customers tend to sit at tables with many other customers producing the cluster behaviour, thought it has an infinite number of mixture components to choose from. | Notice that popular tables become more popular, and that as more customers come in they become less and less likely to sit down at a new table.
[...]. The “dishes” in the CRP correspond to probability density functions, and the process of “ordering” a dish k corresponds to drawing the parameters φk to a PDF from a prior distribution H over those parameters. (For example, each dish k can be a Gaussian with parameters {μk, Σk}= φk ~ H.) The process of a customer t choosing a table zt corresponds to choosing a distribution φzt from which to draw an observation yt [...]. Since customers in the CRP tend to sit at tables with many other customers, the DPMM tends to draw points from the same mixture components again and again even though it has an infinite number of mixture components to choose from. |
Kein Quellenverweis zu finden, obwohl der Text weitgehend wörtlich mit der Quelle übereinstimmt (wobei die Variablen anders benannt sind). Man beachte den sinnlosen ersten Satz in der Dissertation, der aber trotzdem wörtlich mit Satzfragmenten aus der Quelle übereinstimmt. |
