Artificial intelligence has advanced rapidly in the last decade, driven primarily by progress in the scale of deep-learning systems. Despite these advances, the creation of intelligent systems that can operate effectively in diverse, real-world environments remains a significant challenge. In this white paper, we outline the Thousand Brains Project, an ongoing research effort to develop an alternative, complementary form of AI, derived from the operating principles of the neocortex. We present an early version of a thousand-brains system, a sensorimotor agent that is uniquely suited to quickly learn a wide range of tasks and eventually implement any capabilities the human neocortex has. Core to its design is the use of a repeating computational unit, the learning module, modeled on the cortical columns found in mammalian brains. Each learning module operates as a semi-independent unit that can model entire objects, represents information through spatially structured reference frames, and both estimates and is able to effect movement in the world. Learning is a quick, associative process, similar to Hebbian learning in the brain, and leverages inductive biases around the spatial structure of the world to enable rapid and continual learning. Multiple learning modules can interact with one another both hierarchically and non-hierarchically via a "cortical messaging protocol" (CMP), creating more abstract representations and supporting multimodal integration. We outline the key principles motivating the design of thousand-brains systems and provide details about the implementation of Monty, our first instantiation of such a system.

The question of whether the nervous system produces movement through the combination of a few discrete elements has long been central to the study of motor control. Muscle synergies, i.e. coordinated patterns of muscle activity, have been proposed as possible building blocks. Here we propose a model based on combinations of muscle synergies with a spe- cific amplitude and temporal structure. Time-varying synergies provide a realistic basis for the decomposition of the complex patterns observed in natural behaviors. To extract time-varying synergies from simultane- ous recording of EMG activity we developed an algorithm which extends existing non-negative matrix factorization techniques.

In Samuel Beckett's novel, The Unnamable, the anonymous narrator laments, "I'm all these words, all these strangers, this dust of words, with no ground for their setting, no sky for their dispersing." For Beckett's narrator, words have become unmoored from their meaning. They no longer refer to anything in the physical world. Ultimately, they fail to fully convey or contain the inner message that prompted them. It's a deeply unsettling feeling I suspect we've all experienced. Words become disconnected from our emotions, insufficient for what we want to convey.

Social robot company Jibo is sadly running on fumes after burning through nearly $73 million in funding. In a story first reported by BostInno and since confirmed by The Robot Report, Jibo has laid off the majority of its workforce to enable "additional time to secure additional funding or pursue an exit." Jibo was once heralded as "the first social robot for the home." Founded in 2012 by famed MIT roboticist Cynthia Breazeal, Jibo successfully raised over $3.5 million when its Indiegogo campaign ended in 2014. At the time, Breazeal promised to usher in a new age of social robotics.

Toddler's brains are far more advanced than thought, a new study has found. Researchers discovered seven month old's have basic social skills - and can already understand what their parents are doing. It is the first time babies have been shown to not only observe, but understand social interactions. Researchers discovered seven month old's have basic social skills - and can already understand what their parents are doing. The study involved 36 seven-month-old infants, who were each tested while wearing a cap that used electroencephalography, or EEG, to measure brain activity.

In fact, goal-driven hierarchical structure to concatenate simple human behavior is mostly constituted by goal-directed motor acts. This hierarchical goal structure as well as the actions based on the synergic composition of simpler rules, which connect individual motor elements, might be motor constituents chained together according to a precise paralleled to the syntactic organization of language.

The two-thirds power law, an empirical law stating an inverse nonlinear relationship between the tangential hand speed and the curvature of its trajectory during curved motion, is widely acknowledged to be an invariant of upper-limb movement. It has also been shown to exist in eyemotion, locomotion and was even demonstrated in motion perception and prediction. This ubiquity has fostered various attempts to uncover the origins of this empirical relationship. In these it was generally attributed either to smoothness in hand-or joint-space or to the result of mechanisms that damp noise inherent in the motor system to produce the smooth trajectories evident in healthy human motion. We show here that white Gaussian noise also obeys this power-law. Analysis of signal and noise combinations shows that trajectories that were synthetically created not to comply with the power-law are transformed to power-law compliant ones after combination with low levels of noise. Furthermore, there exist colored noise types that drive non-power-law trajectories to power-law compliance and are not affected by smoothing. These results suggest caution when running experiments aimed at verifying the power-law or assuming its underlying existence without proper analysis of the noise. Our results could also suggest that the power-law might be derived not from smoothness or smoothness-inducing mechanisms operating on the noise inherent in our motor system but rather from the correlated noise which is inherent in this motor system.

Behavioral goals are achieved reliably and repeatedly with movements rarely reproducible in their detail. Here we offer an explanation: we show that not only are variability and goal achievement compatible, but indeed that allowing variability in redundant dimensions is the optimal control strategy in the face of uncertainty. The optimal feedback control laws for typical motor tasks obey a "minimal intervention" principle: deviations from the average trajectory are only corrected when they interfere with the task goals. The resulting behavior exhibits task-constrained variability, as well as synergetic coupling among actuators--which is another unexplained empirical phenomenon.
