Numenta’s deep experience in theoretical neuroscience research has led to tremendous discoveries about how the brain works. We have developed a framework called the Thousand Brains Theory of Intelligence that will be fundamental to advancing the state of artificial intelligence and machine learning. By applying this theory to existing deep learning systems, we are addressing today’s bottlenecks while enabling tomorrow’s applications.
We are a team of scientists and engineers applying neuroscience principles to machine intelligence research.
To reverse-engineer the neocortex and to enable machine intelligence technology based on cortical theory.
We believe the brain is the best example of an intelligent system. The brain’s center of intelligence, the neocortex, controls a wide range of functions using a common set of principles.
Today’s machine learning and AI have accomplished many impressive tasks but are restricted to narrow, specific goals. In stark contrast, intelligent machines continuously learn patterns in their environment without supervision, enabling them to tackle problems in entirely new ways. Intelligent machines that learn will have an enormous beneficial impact in the coming decades, and the neocortex provides the blueprint for building them.
Numenta has developed a novel theory and broad framework for understanding what the neocortex does and how it does it, called the Thousand Brains Theory of Intelligence. We have built a robust roadmap that lays out the steps to achieving truly intelligent machines based on the key principles of the Thousand Brains Theory.
We are one of the few teams that has developed large-scale theories of the brain that are biologically constrained, testable, and implemented in software.
Our deep neuroscience research provides the foundation for delivering transformational changes in machine learning and AI. We document our research in several ways, including peer-reviewed journal papers, conference proceedings, and invited talks. In addition, we place our research commits in an open-source project. We strive to be completely open in everything we do.
Our neuroscience research has uncovered a number of core principles that are not reflected in today’s machine learning systems. These principles have the promise to solve many of the known problems today’s machine learning and AI systems face. By incorporating these principles, we can overcome today’s limitations and build tomorrow’s intelligent machines.
We recently released two research papers detailing how the principles of The Thousand Brains Theory lead to the development of more efficient and robust machine learning systems.
Avoiding Catastrophe: Active Dendrites Enable Multi-Task Learning in Dynamic Environments – Frontiers in Neurorobotics
Representations in the brain are highly sparse, resulting in an extremely efficient system. For machine learning, sparsity also offers the promise of significant computational benefits, but most hardware architectures are not optimized for extreme sparsity. These limitations have hindered research into sparse models. Along with our hardware partners, we are developing methods for dramatically improving the computational efficiency of sparse neural networks.
In the brain, cortical networks are sparsely connected and extremely dynamic. As many as 30% of the connections in the neocortex turn over every few days. We are investigating ways to create highly sparse networks that learn their structure dynamically through training.
Our neuroscience research has shown that sparse representations are more robust and stable than dense representations. We have developed a cortically inspired sparse algorithm that can be applied to deep learning networks trained through backpropagation. These networks have both sparse activations and sparse connections. Sparse networks achieve accuracy competitive with the state of the art dense models, but are significantly more robust to noise.
Truly intelligent machines must have the capability to learn and adapt continuously, a property that is absent in today’s deep learning systems. In the brain, sparse representations plus a more complex neuron model, enables us to continuously learn new patterns in an unsupervised manner. Incorporating these ideas into artificial neural systems can enable systems that learn continuously from streaming data without any manual interventions.
Long term, our focus is on enabling the creation of truly intelligent machines that understand the world. Future research projects may include:
Vernon Mountcastle proposed that because every part of the neocortex has the same complex circuitry, then every part is doing the same thing. Therefore, if we can understand a cortical column, we will understand the neocortex.
Through our focus on cortical theory, we seek to understand the complex circuitry of a cortical column. We want to understand the function and operation of the laminar circuits in the brain, including what the neurons are doing, what the layers are doing, how they interact, and how a cortical column works.
We are often asked how we do neuroscience research at Numenta and what it means to focus on cortical theory. We read many neuroscience papers and published results to get a deep understanding of neuroanatomy, neurophysiology, and cortical function. We propose theories about how the detailed architecture of the neocortex implements these functions. We ensure our work satisfies biological constraints and test our theories via simulation. Since we do not do any wet lab work, we collaborate with experimentalists that run investigations and give us feedback.
We document our research in several ways, including peer-reviewed journal papers, conference proceedings, research reports, and invited talks. In addition, we place our daily research commits in an open source project and answer questions about our research posted on our forums . We strive to be completely open in everything we do.
Although there is much to do, we have made significant progress on filling in the pieces of the common cortical circuit that underlines all of intelligence. We have proposed a novel theory and broad framework for understanding what the neocortex does and how it does it. We have made discoveries on how neurons make predictions, the role of dendritic spikes in cortical processing, how cortical layers learn sequences, and how cortical columns learn to model objects through movement.
Building on Mountcastle’s proposal that the neocortex is made up of nearly identical cortical columns, we are working on filling in the pieces of the cortical circuit – understanding each layer, what the neurons are doing, and how a cortical column works. As part of this research, we have proposed a framework, consistent with anatomical and physiological evidence, that explains how cortical columns function. The framework is based on how cortical columns learn sensorimotor models of the world by combining sensory inputs with location signals.

Memory and recall of sequences is an essential component of inference and behavior. We believe that sequence memory is occurring in multiple layers of the neocortex. We’ve shown how a layer of pyramidal neurons with active dendrites, arranged in mini-columns, will learn transitions of patterns and form a robust sequence memory.

Sparse Distributed Representations (SDRs) are a foundational aspect of all of our theories. Everywhere in the neocortex, information is represented by distributed and sparsely active sets of neurons. We have shown through mathematical analysis and simulation that SDRs enable semantic generalization and robustness.

We have a growing collection of published peer-reviewed papers, supplemental white papers and research manuscripts. You can search our publications by category or by year. Some are currently under review at journals/conferences, but we have made all manuscripts freely available on preprint sites, such as arXiv or bioRxiv. Our goal is to document all of our discoveries in scientific journals.
HTM (Hierarchical Temporal Memory) is an algorithmic implementation of the Thousand Brains Theory. HTM builds models of objects and makes predictions using sensory input. It generates motor commands to interact with its surroundings and continuously test its predictions. This continuous testing allows HTM to update its predictive models, and thus its knowledge.
