Einstein's equation is $E = mc^2$.

The function $f(x) = ax^2 + bx + c$ is a quadratic.

A vector $\mathbf{v} = (v_1, v_2, \ldots, v_n)$.

Set notation: $\{x \in \mathbb{R} \mid x > 0\}$.

Greek letters: $\alpha, \beta, \gamma, \delta, \epsilon, \theta, \lambda, \mu, \pi, \sigma, \omega$.

Operators: $\sum_{i=1}^n$, $\prod_{i=1}^n$, $\int_a^b$, $\lim_{x \to 0}$.

Gradient descent is a first-order iterative optimization algorithm
for finding a local minimum of a differentiable function.

\begin{theorem}[Universal Approximation Theorem]
\label{thm:universal_approximation}
A feedforward network with a single hidden layer containing
a finite number of neurons can approximate any continuous function
on a compact subset of $\mathbb{R}^n$.
\end{theorem}

\begin{proof}
Follows from the Stone-Weierstrass theorem...
\end{proof}

This assumes activation functions are non-polynomial.

\begin{frame}{Transformer Architecture}
    
    The transformer uses self-attention mechanisms:

    \]

        \begin{enumerate}
            \item Multi-head attention

% Error: "! Undefined control sequence"
% Solution: Missing package
\usepackage{amsmath}   % For \mathbb, \mathcal, etc.
\usepackage{graphicx}  % For \includegraphics
\usepackage{hyperref}  % For \url, \href

% Error: "! LaTeX Error: File `*.eps' not found"
% Solution: Use PDF images or convert
% Or use: \usepackage{epstopdf}

% Error: "! Package inputenc Error: Unicode character"
% Solution: Use xelatex or lualatex
% Or: \usepackage[utf8]{inputenc}

% Error: "Overfull \hbox"
% Solution: Reword or use
\sloppy  % Less strict line breaking
% Or: \usepackage{microtype}  % Better character protrusion

% Error: "! Bibliography not compatible with author-year"
% Solution: Use consistent style
% biblatex with style=apa requires biber, not bibtex

% Warning: "No file *.bbl"
% Solution: Run bibtex/biber after pdflatex
