Seeing the Brain Predict in Real-Time: An Animated Python Journey
I n our previous post, we explored the core idea of the Free Energy Principle – the brain as a prediction machine striving to minimize the difference between its expectations and sensory reality. We even built a simple Python program to demonstrate this. Now, let's take it a step further and visualize this predictive process as it unfolds. We've enhanced our Python code to create a dynamic animation, giving us a glimpse into how an "internal belief" (our brain's model) continuously adapts to incoming "sensory input." Animating the Prediction: Our Updated Python Code Python import numpy as np import matplotlib.pyplot as plt import matplotlib.animation as animation def generate_world_state ( time_step ): """A simple, changing "world" state.""" return np.sin( 0.1 * time_step) + np.random.normal( 0 , 0.1 ) def generate_sensory_input ( world_state ): """Sensory input with some ...
