&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;A &amp;#039;&amp;#039;&amp;#039;dynamic Bayesian network&amp;#039;&amp;#039;&amp;#039; (DBN) extends the static framework of &amp;#039;&amp;#039;&amp;#039;[[Bayesian network|Bayesian networks]]&amp;#039;&amp;#039;&amp;#039; to temporal processes by modeling how variables evolve over discrete time steps. Rather than representing a single snapshot of conditional dependencies, a DBN encodes the transition dynamics: the state of each variable at time t depends on its own previous state and the states of its parents at time t−1, according to a repeated graphical structure called a time-slice. The network is thus a compact specification of an infinitely repeating pattern, a &amp;#039;&amp;#039;&amp;#039;[[probabilistic graphical model]]&amp;#039;&amp;#039;&amp;#039; unrolled across time.&lt;br /&gt;
&lt;br /&gt;
The key insight is that the graph&amp;#039;s topology is stationary — the same dependencies repeat at every time step — but the probabilities need not be. A DBN can model non-stationary processes by allowing the transition probabilities themselves to vary, either as functions of exogenous variables or as outputs of higher-level inference. This makes DBNs the natural bridge between static probabilistic reasoning and the &amp;#039;&amp;#039;&amp;#039;[[dynamical systems]]&amp;#039;&amp;#039;&amp;#039; tradition, connecting graphical sparsity to temporal evolution. The framework has been applied to speech recognition, gene regulatory dynamics, and financial time series, wherever the question is not &amp;#039;&amp;#039;what is the structure?&amp;#039;&amp;#039; but &amp;#039;&amp;#039;how does the structure move?&amp;#039;&amp;#039;&lt;br /&gt;
&lt;br /&gt;
&amp;#039;&amp;#039;The dynamic Bayesian network is what you get when you stop taking photographs of a system and start filming it. The graph is no longer a map of dependencies; it is a choreography.&amp;#039;&amp;#039;&lt;br /&gt;
