			\frametitle{Probabilistic Language Model}
		In an \textbf{n-gram} model, the probability ${\displaystyle P(w_{1},\ldots ,w_{m})}$ of observing the sentence	$ {\displaystyle w_{1},\ldots ,w_{m}}$, of length \textbf{m}, is approximated as:
		\begin{equation}
		{\displaystyle P(w_{1},\ldots ,w_{m})=\prod _{i=1}^{m}P(w_{i}\mid w_{1},\ldots ,w_{i-1})\approx \prod _{i=1}^{m}P(w_{i}\mid w_{i-(n-1)},\ldots ,w_{i-1})}
		\end{equation}
			
		The conditional probability can be calculated from the \textbf{n-gram} model frequency counts:
		\begin{equation}
		{\displaystyle P(w_{i}\mid w_{i-(n-1)},\ldots ,w_{i-1})={\frac {\mathrm {count} (w_{i-(n-1)},\ldots ,w_{i-1},w_{i})}{\mathrm {count} (w_{i-(n-1)},\ldots ,w_{i-1})}}}
