Neural Networks & Visualisation

In this episode, we explore neural networks through a rigorous comparison with visualisation, grounded in neuroscience rather than motivational folklore. Neural networks learn by repeatedly exposing themselves to data, adjusting internal parameters to reduce error, and reinforcing pathways that lead to better predictions. This process closely mirrors how the human brain learns through mental imagery, attention, and repetition. In neuroscience, visualisation is not imagination in the abstract sense, but the activation of sensory and motor cortices in the absence of direct stimuli. Brain imaging studies show that when we visualise an action, posture, or outcome, many of the same neural circuits fire as when we physically perform it. This is why visualisation is widely used in rehabilitation, sports training, and motor learning. Similarly, neural networks: • Activate layers (neurons) in response to inputs • Strengthen connections through repetition (weight updates) • Reduce prediction error through feedback (loss minimisation) • Generalise patterns beyond the training examples Visualisation works through the same principles: • Attention acts as a feature selector • Repetition reinforces neural pathways (Hebbian learning) • Feedback from bodily sensation refines the mental model • Prediction improves as the brain updates its internal representation We also explore the limits of visualisation. Just as neural networks can overfit when trained on narrow or biased data, the brain can reinforce inaccurate internal models if visualisation is not paired with sensory feedback and real-world correction. Learning—whether biological or artificial—requires both simulation and validation. By comparing neural networks with visualisation, we clarify what learning truly is: not wishful thinking, but iterative pattern recognition, error correction, and adaptation. This episode bridges machine learning, neuroscience, and embodied cognition to show how both brains and models learn—not through magic, but through structure, repetition, and feedback. #NeuralNetworks #DeepLearning #SelfRegulation #NervousSystem #IdentityShift #AIExplained #MachineLearning #SelfDevelopment #Prompt2Self
