19 Mar Fuzzy Logic Section Intro

Spock

Why do we find Mr. Spock, Commander Data or C3P0 so lovable? We have all known people like them: they are the ones who see the world in black and white. Spock had an excuse – he was a Vulcan who knew a lot. Computers, on the other hand, can be downright exasperating when they get […]

13 Mar Probability and Expectations

Statistical Probability Roulette

The sun is pretty likely to rise tomorrow – you can have confidence in that, but it is sometimes said that “there is no guarantee.” Scheduling meetings tomorrow based on the sunrise assumption is a safe bet, but there may be any number of other things that interfere with the meeting. Life is filled with […]

06 Mar Inference in the Face of Uncertainty

Artficial Intelligence

Do you know what I’m about to say? If your mind were not able to race ahead of the words and build a set of expectations about what comes next, you may not be able to understand me speaking or writing. But you can predict a lot more than your conscious awareness tells you. A […]

05 Mar Decide on Fuzzy Logic

In this section of Understanding Context, we describe not just how people think, but how they use their thoughts to guide their actions. We are particularly concerned with how people integrate multiple ideas or constraints into their thinking and decision-making processes, then put those decisions into action. It is sometimes said that the difference between information […]

01 Mar Hold Onto the Memories

When you see Grandmother, is there a cell or cluster of cells in your brain that light up and say: “I recognize that face – It’s Grandmother!” The Grandmother cell theory suggests that there is such a cell or group of cells where that knowledge is explicitly stored. Earlier posts included a discussion of feature selectivity […]

21 Feb Pattern Recognition in Two Dimensions

ANS Network

Perceptual Grid We live in three dimensional space, and understanding three dimensions is critical to our ability to go places and do things, but we comprehend things in many dimensions. Our senses, however, tend to flatten things out. Images are projected on our light-sensitive retinas in exactly two-dimensional patterns. The rods and cones possess light-sensitive […]

12 Feb Conscious Phenomena

Conscious or Psychic

Conscious Phenomena For the past few posts, I have been exploring consciousness. Extra-sensory perception is a part, or an extension of consciousness. Are you sometimes psychic?  Some people have truly remarkable extra-sensory capabilities while others do not. I read a short story by Ursula K. Le  Guin, though I can’t for the life of me remember the […]

06 Feb Nature vs Nurture in Intelligence

Nature vs Nurture in Intelligence

The three deep roots of intelligence are biological (built into the flesh), cognitive (based on our unique mental responses to stimuli), and psychosocial (learned through culture-laden experiences). Language springs from the same roots, and becomes inseparably intertwined with intelligence. I came across this article in The Creativity Post that corroborated ideas I have been working on for […]

27 Jan Go With the Flow

Brain Flow

Modeling Neural Electrical Flow Patterns From looking at possible mechanisms for information storage, we move back to its movement. It may be important to understand the patterns of electrical flow in the brain to define good models for artificial systems that attempt to match human competence in cognitive processing tasks. This is what neural network and […]

25 Jan The Chromophore as Digital Bit

Brain Data

I have opined in prior posts that the skeletal components that give structure to axons and dendrites, especially microtubules, may play a larger role in cognition than previously thought. The illustration of microtubule structure at right shows how the alpha and beta tubulin dimers string themselves together to make protofilaments, which further join one another […]
