 The hypothesis behind this experiment is that high-level abstract

+thinking is fueled by social competition.
+
+A group of communicating agents that try to demonstrate their
+cognitive superiority would end up developing a rich and consistent
+culture.
+
+\subsection{Setup}
 
 The experiment is designed with a group of GPTs that alternatively
 learn to solve quizzes and generate new ones.
 
-A ``quiz'' is a triplet of the form $(A, d, B)$ where $A$ and $B$ are
-two sequences and $d$ is a token indicating if the direction is
-forward or backward. Given $(A, d)$, the challenge is to generate $B$.
+A ``quiz'' is a pair composed of a prompt and a solution, both being
+sequence of tokens.
+
+We differentiate \textbf{world quizzes} that follow pre-defined and
+fixed regularities, and mimic the world's physical and environmental
+patterns that an organism has to grasp to survive, and \textbf{culture
+  quizzes} that are generated by the GPTs, and mimic the knowledge one
+has to master to perform socially.
+
+
+We train five GPTs on a a very large set of ``world quizzes''
+generated randomly. These models are trained to generate both the
+solution given the prompt, and the prompt given the solution.
+
+This is achieved by using for training both ``forward sequences'',
+composed of a token \texttt{[fwd]}, followed by the prompt's tokens,
+followed by another token \texttt{[fwd]}, followed by the solution's
+tokens, or ``backward sequences'' composed of a token \texttt{[bck]},
+followed by the solution's tokens, followed by another token
+\texttt{[bck]}, followed by the prompt's tokens,
+
+\subsection{Generating Culture Quizzes}
+
+When their accuracy get above $95\%$ we generate new quizzes as follows:
+%
+\begin{enumerate}
+
+\item generate a solution (without conditioning) at temperature $T=2$,
+  then generate a prompt for that solution at temperature $T=1/2$, and
+  then generate a solution for that prompt at temperature $T=1/2$.
+
+\item generate one solution for that prompt with each of the $5$ GPTs
+  at temperature $T=1$, if $4$ of them generate the correct solution,
+  validate that quiz and include it in the training data.
+
+\end{enumerate}
+
+This criterion assures that the new quizzes are both solvable and
+sophisticated, and incrementally complexify the culture. Imposing both
+direction prevents the generation of quizzes which are not trivial
+only because the prompt has been randomly degraded.

+\section{Grid Quizzes}
+
+\subsection{World Quizzes}
+
+We define several types of quizzes and implement algorithmic
+procedures to generate randomly example from each.
+
+In these quizzes, the prompt is made of three grids $A, f(A), B$ and
+the solution is a single grid $f(B)$.
+
+\subsubsection{Half Fill}
+
+\pic{pics/task_color_grow.png}{``half fill''}
+
+The first grid contains three rectangles, each with a vertical or an
+horizontal line of another color in its middle. The second grid is
+identical with one of the rectangle having one half filled. The third
+grid contains three rectangles of identical colors as the firs grid,
+of different size and locations. The solution is obtained by filling
+similarly one of the half of a rectangle of the third image.
+
+\subsubsection{Detect}
+
+\pic{pics/task_detect.png}{``detect''}
+
+The first grid contains three rectangles, the second has two pixels of
+same colors located in the top-left corner of two of them. The
+solution is obtained by marking in the fourth image the top-left
+corners of the rectangles of same colors in the third.
+
+\subsubsection{Frame}
+
+\pic{pics/task_frame.png}{``frame''}
+
+The first grid contains three rectangles, and the second is identical
+except that one rectangle has been replaced by its frame. The same
+should be done to the similarly colored rectangles of the third grid
+to obtain the solution.
+
+\subsubsection{Grow}
+
+\pic{pics/task_grow.png}{``grow''}
+
+The first grid contains three rectangles, one of them getting one
+pixel thicker or thinner in the second. The same should be done to the
+similarly colored rectangles of the third grid to get the solution.
+
+\subsubsection{Replace color}
+
+\pic{pics/task_replace_color.png}{``replace color''}
+
+The first grid contains three rectangles, the second is obtained by
+changing one of the colors. The same should be done to the third grid
+to obtain the solution.
+
+\subsubsection{Translate}
+
+\pic{pics/task_translate.png}{``translate''}
+
+The first grid contains three rectangles. The second is obtained by
+displacing one of them by one pixel in both direction. The solution is
+obtained by applying the same motion to the similarly colored
+rectangle in the third grid.
+
+%% \subsubsection{Bounce}
+
+%% \pic{pics/task_bounce.png}{``bounce''}
+
+%% The solution should join the two pixels of same color, with a path of
+%% another color, starting in the direction indicated by a pixel of that
+%% color, and changing direction only when colliding with a pixel of a
+%% third color or one of the lattice border.
+
+%% \subsubsection{count}

 \section{Bird World}
 
+These results were obtained with a slightly different procedure. In
+particular the quizzes were validated if the models could predict both
+the solution from the prompt and the prompt from the solution. We
+report them since they exhibit the same patterns of generalization
+although they are quite different.
+
+\subsection{World Quizzes}
+
 The initial set of quizzes consist of predicting the dynamics of a
 very simple world: A $6 \times 8$ grid with three colored ``birds'' moving in
 a straight line, possibly bouncing on the grid's borders. There are
 ten different colors.

+\birdpic{pics/examples_train.png}{}
 %
 
-\vspace*{-2ex}
-
 In each on these quizzes, $A$ is the left image serialized in
 raster-scan order as a sequence of $6 \times 8 = 48$ tokens, $d$ is
 either the token ``forward'' or the token ``backward'', and $B$ is the
 right image, also serialized. The direction of prediction is chosen at
 random.
 
-\section{Generating Quizzes}
+\subsection{Culture quizzes}
 
-Given a set of $N$ GPTs, we can generate new quizzes as follows:
-Select one of the models, and use it to generate the $97$ tokens of a
-triplet $(A, d, B)$.
+This procedure results in the discovery of patterns which are not
+present in the original quizzes:
 
-Then with each one of the $N-1$ other models, predict $B$ from $(A,
-d)$, and $A$ from $(B, d')$ where $d'$ is the direction token opposite
-of $d$.
+\begin{example}
 
-A quiz is validated if \textbf{all the other GPTs but one predict it
-  deterministically correctly in both directions.}
+\birdpic{pics/4_birds_1.png}{}
 
-This criterion assures that the new quizzes are both solvable and
-sophisticated, and incrementally complexify the culture. Imposing both
-direction prevents the generation of quizzes which are not trivial
-only because the prompt has been randomly degraded.

-\section{Overall Process}
+\birdpic{pics/6_birds_1.png}{}
 
-The overall process consists of training the GPTs from scratch by
-iterating the following steps:
-%
-\begin{itemize}
+More birds.
 
-\item select the GPT with the lowest recorded test accuracy, train it through one epoch,
+\end{example}
 
-\item if its test accuracy gets above $97.5\%$, generate $1'000$ new
-  quizzes, add them to the training set, re-compute the accuracy of
-  all the models
