\section{Introduction}

\begin{frame}{Motivation}
  \begin{itemize}
    \item State the problem and why it matters.
    \item Summarise the gap in existing work.
    \item Preview your contribution in one sentence.
  \end{itemize}
  \vskip6pt
  \begin{block}{Key idea}
    The single most important takeaway, phrased so the audience remembers it.
  \end{block}
\end{frame}

\section{Approach}

\begin{frame}{Method}
  \begin{columns}[T]
    \begin{column}{0.54\textwidth}
      Describe the approach in steps:
      \begin{enumerate}
        \item First component
        \item Second component
        \item How they combine
      \end{enumerate}
    \end{column}
    \begin{column}{0.42\textwidth}
      The objective we minimise:
      \[
        \mathcal{L}(\theta) = \frac{1}{n}\sum_{i=1}^{n} \ell\!\left(f_\theta(x_i), y_i\right)
      \]
      where $\theta$ are the parameters.
    \end{column}
  \end{columns}
