12 Nov Context Powers Backward Chaining Logic
A popular success strategies book suggests that if we “Begin with the End in Mind” we are likely to get where we’re going more consistently. We wander less if we think about what we want at the end from the very first steps of our journeys. Context helps us do that. Human behaviorists and philosophers have […]
10 Nov Seeking a Universal Theory of Knowledge
As a fundamental premise for this post, this blog as a whole, and my life’s work, I propose that language and “real world knowledge” are inextricably connected, and neither functions well without the other. This is why, in my opinion, natural language processing (NLP) initiatives focusing exclusively, or even primarily on language structure have significant […]
05 Nov Evolution of Language
Evolution of Language Did humans become smart by necessity? With the forces of nature combined to rig the test for “survival of the fittest”, as human evolution from lower forms, how did these ill-equipped creatures, with their weak jaws and thin hides, make the natural-selection cut? It sounds like it was a perilous journey. One […]
15 Sep What is Inside Neurons?
Intracellular Structure of Neurons In earlier posts, we examined the brain, its areas, and the types of neurons that populate the different layers of some of the brain’s areas. In this post and more to follow, we will turn up the magnification and look a little deeper. What can be seen inside the cells? What […]
05 Sep Brain Form and Function
Functional Morphology I’ve addressed questions related to modeling form, function and process in an earlier post. Today’s post drills down in some specific areas to point out some important connections between form and function that could contribute to engineering systems that more accurately model the human brain. Paul Churchland suggests that many AI initiatives have […]
31 Aug Building a Cathedral of Knowledge
Good fiction, especially good historical fiction, gets my brain spinning. Ken Follett‘s The Pillars of the Earth and World Without End describe the technology, born in the “Dark Ages” in which mortal men were able, with limited technologies, to build edifices that could stand throughout the ages. At the same time as Mr. Follett’s mythical cathedral […]
30 Aug Eclecticism and Cognitive Modeling
Cognitive Science Hybrids in plants and automobiles are great. Perhaps in computers and apps as well. I have always thought of myself as deeply interested in the “cross-pollination of ideas.” This includes, when appropriate, snipping sequences and splicing to create genetically modified innovations. The posts in the Understanding Context blog span the knowledge and theories […]
29 Aug Layers of Brain Complexity
Hierarchy: A Structural Aspect of Thought The complexity of the cerebrum is necessitated by its function as the center of cognition. Before looking at cerebral structure, consider some of the functions of thought. Thinking involves accessing memory to find what perceived data is stored, what other data in memory it is associated with, and what is the […]
29 Aug Black Boxes: Specialized Areas of the Brain
The Black Box Black Box is a term used to describe a mechanical device that does something inside, but whose functions are not visible from the outside. Specialized areas of the brain may operate as black boxes. Activation flows in and activation flows out, and what happens inside may have no direct affect on other […]
28 Aug Sensory Input to the Brain
Part of the definition of any computer program is defining the inputs and outputs, where they come from, what they are and where they get processed. Fortunately, we know enough about the brain to answer many of these questions, thus we have a basis for defining artificial models that, in some way, mimic these elements of […]
