Once upon a time, in a land far, far away, there lived a group of animals who loved to play with numbers. They were especially interested in learning how to measure the accuracy of their predictions. One day, they heard about a magical thing called "Bayes Theorem" that could help them do just that.

Excited to try it out, the animals gathered around Bayes and asked him to teach them everything he knew. Bayes smiled and began to explain, but soon realized that the animals didn't understand a word he was saying.

Determined to make it fun and easy for them to learn, Bayes came up with a game. He would hide some nuts in the forest and the animals would try to guess where they were. The animal with the highest accuracy in guessing where the nuts were would win.

The first round was called "Bagging." Each animal took turns guessing and the winner was the one with the most accurate guesses. But to the animals' surprise, Bayes informed them that their guesses were biased. This meant that they were only guessing the same spots over and over again, without considering other possibilities.

The second round was called "Boosting." This time, Bayes would give each animal feedback on their previous guesses, helping them to reduce their bias and improve their accuracy. The animals worked together and learned from each other's mistakes, and soon enough, their accuracy improved dramatically.

Finally, Bayes introduced a new concept called "Batch." This meant that the animals would have to guess all at once, rather than one by one. The animals were intimidated at first, but with their newfound knowledge and improved accuracy, they aced the final round.

In the end, all the animals were declared winners and celebrated their newfound love for numbers and Bayes Theorem. And from that day on, the animals never forgot the importance of reducing bias, improving accuracy, and working together as a batch.

The end.
