The thought experiment explores how any system can autonomously learn to correct predictive errors in a changing world filled with unexpected events. The experiment focuses on the principle of sufficient reason and the role of reason in scientific theorizing. It poses two main questions: how can a coding error be corrected if no individual cell is aware of it, and how can a system learn to recognize and predict patterns in a changing environment? The experiment highlights the need for autonomous, self-correcting mechanisms in learning and adaptation.
The neural models developed in the experiment operate autonomously and can learn unsupervised or supervised. These models include bottom-up adaptive filters and top-down learned expectations, which allow for learning recognition categories and predicting future events. The hierarchical resolution of uncertainty and the use of complementary computing is key in these models. The interaction between laminar circuits, feedforward and feedback processing, and horizontal interactions enable the unification of various intelligent capabilities, making them suitable for designing artificial intelligence algorithms and mobile robots. The models demonstrate the power of a canonical cortical circuit and the potential for general-purpose autonomous adaptive intelligence.
Surface shroud resonances explain how we consciously see visual objects and scenes and control actions such as looking and reaching. The hierarchical resolution of uncertainty and the completion of incomplete boundary and surface representations play a crucial role in this process. The interaction between multiple cortical columns and the formation of shroud-like spatial attention in posterior parietal cortex contribute to conscious vision and action control. These models can also shed light on how unexpected visual cues might disrupt the perception process.
The paradigm of laminar computing offers a unified approach to understand and connect various neural models and functions. The six main layers of the neocortex, including vision, object recognition, speech, language, and cognition, all operate through variations of a single canonical cortical circuit. By realizing these circuits in VLSI chips, we can move towards achieving general-purpose autonomous adaptive intelligence. This approach has the potential to revolutionize engineering, technology, and artificial intelligence by creating self-contained and specialized systems that embody different intelligent capabilities.
This podcast episode explores a biological neural network model that explains how children learn to understand language meanings. The model highlights the role of various self-organizing brain processes, including conscious perception, joint attention, object learning, cognitive working memory, and emotion-cognition interactions. These processes enable children to learn language meanings by interacting with adult teachers and experiencing perceptual and affective events together. The model contrasts human capabilities with AI models, emphasizing the importance of self-organized meaning in language learning. The episode also delves into the challenges and criticisms faced by the theory and addresses them through rigorous mathematical formulations and real-time adaptation to changing environments.
Another fascinating aspect discussed in the podcast is the exploration of how visual artists create paintings and how humans perceive them. The speaker specifically mentions the work of artists like Henri Matisse and explains how their artistic styles and techniques tap into the brain's ability to complete invisible boundaries. The discussion highlights that human perception involves completing invisible boundaries to recognize objects and comprehend visual art. This insight adds a new dimension to understanding the relationship between art, vision, and cognitive processes. The speaker also mentions that further exploration of this topic can be found in their book and web page, which provide more detailed insights and examples.
Towards the end of the podcast, the speaker reflects on their journey and offers advice to future philosophers and scientists. They emphasize the importance of reading published literature and avoiding redundant work. The speaker shares their passion for problem-solving, urging young researchers to find a problem they are genuinely passionate about. Furthermore, they encourage individuals to consider teaching as a noble profession and highlight the diverse career opportunities outside of academia, emphasizing the need for making a positive impact in the world. The speaker also discusses their plans for the future, mentioning the ongoing work on a new book while remaining open to new ideas and research projects that may arise along the way.
