Bayesian network

IPA（発音記号）

/ˈbeɪ.zjən ˈnɛt.wɜːk/

名詞

(statistics) A directed acyclic graph whose vertices represent random variables and whose directed edges represent conditional dependencies. Each random variable can fall into any of at least two mutually disjoint states, and has a probability function which takes as inputs the states of its parent nodes and returns as output the probability of being in a certain state for a given combination of the states of its parent nodes. A node without parent nodes just has an unconditioned probability of being in some given state.

日本語の意味

ベイズネットワークとは、各頂点が確率変数を表す有向非巡回グラフであり、各辺が条件付き依存性を示す統計的モデルです。 / 各確率変数は、少なくとも2つ以上の互いに排反する状態を取り、親ノードの状態に基づいて、その特定の状態にある確率が決定されます。 / 親ノードを持たないノードは、外部の条件に依存しない、純粋な確率（無条件確率）を持ちます。

The research team constructed a Bayesian network to infer the probability of system failure given multiple sensor readings.

研究チームは複数のセンサーの読み取り値からシステム故障の確率を推定するために、有向非巡回グラフとして表現される確率的グラフィカルモデル（ベイズネットワーク）を構築しました。
