10 Mar The Context of Knowledge
What Is Knowledge? Just like the beautifully structured organization of all things in the physical universe, there is a hierarchy or taxonomy of knowledge. The levels and organization of the hierarchy, as I see them, are shown in the illustration below. Being fascinated by the concept of context, I have decided that, in this model, “context” includes […]
08 Mar In the Middle of a Big Wide World
The guy on the previous post (Your Personal Bubble) represents your typical office worker who sees himself as part of a universal hierarchy or taxonomy, though not exactly where he’d rather be in the big wide world. Each moment, we each learn from our own vantage point. While we can learn about all physical things, from […]
07 Mar Your Personal Bubble
There is time-space context within which we constantly move and place ourselves in the universe. Our constantly moving and evolving personal bubble is the starting point of understanding. Where are you at this very moment? Are you where you want to be? Where am I? Why am I here? Why isn’t the tide washing the […]
06 Mar Inference in the Face of Uncertainty
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 […]
03 Mar Images in Thinking
More or Less Remembering Memory is a subjective thing. Will we ever be able to teach a computer what is memorable in art, music, literature or cinema? A great illustration of memory’s subjectivity is the song from Gigi entitled, “Ah, yes, I remember it well.” In the song’s lyrics, a woman and a man recount […]
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 […]
28 Feb Sense-Perception and Memory
I Recall… Since we have been discussing learning in the past few posts, it seems appropriate to talk about memory here as well. Of course, we are talking about human memory, but computers can remember quite well, too. In fact memory is one of the few areas where it is universally agreed that computers are […]
27 Feb Chomsky, Locke and Aristotle on Learning Language
Inherited Abilities In systems design, there is a growing trend to “hard code” less into the system and leave more to be configured by the person or organization that is using the software. The growth of Rules and Workflow Engines that can be managed by non-technical users is prime evidence of this trend. And yet, the complex instruction […]
26 Feb Physiology of Learning to Generalize
I began this blog heavily concentrating on the physiology of the brain, its cells and the way they interconnect. Learning and association are not dealt with much in those posts other than to describe ways in which the brain and its cells provide mechanisms for these activities. Many of the mechanisms of association are fairly clearly understood […]
