+ An AI system is a machine-based system that, for explicit or implicit objectives, \textbf{infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions} that can influence physical or virtual environments. Different AI systems vary in their levels of autonomy and adaptiveness after deployment.

+ \begin{frame}{License Goals}
+ \begin{itemize}
+ \item Use the system for any purpose and without having to ask for permission.
+ \item Study how the system works and inspect its components.
+ \item Modify the system for any purpose, including to change its output.
+ \item Share the system for others to use with or without modifications, for any purpose.
+ \end{itemize}
+ \end{frame}
+
+ \begin{frame}{What we need}
+ \begin{itemize}
+ \item Data information: Data used to train the system, training methodologies, obtaining data, labeling
+ \item Code: source code of model, pre- and post processing, traing\&testing, libraries, and model architecture
+ \item Weights: weights, (hyper)parameters, intermediate steps, final result
