31 Mar Truth, Belief and Confidence
Establishing frameworks for truth, belief and confidence can be part of raising a child and part of building a more intelligent system. Parents in households of faith often feel a compelling need to teach their children about things that are outside the realm of scientific discovery. In espionage, intelligence analysts review information collected by agents, electronic snoops, and […]
28 Mar Is Everything Black or White?
We have exercised our abstract ideas about that which is too big and chaotic for us to understand (everything), let’s take a glimpse at that which is so small and chaotic that we may never really figure it out: the workings of the mind. In the next few posts, we will examine different forms of logical […]
27 Mar Cognition and Emotion
I’m conflicted. I suspect you are too. “Since the time of the ancient Greeks, humans have found it compelling to segregate reason from passion, thinking from feeling, cognition from emotion. These contrasting aspects… have in fact often been viewed as waging an inner battle for control of the human psyche” (LeDoux, 1996, p. 24). In earlier […]
26 Mar Bayes and Search Theory
What began as a study of belief has turned into a strategy for solving very complex problems. Thomas Bayes (/ˈbeɪz/; 1701–1761) proposed a model in which adding evidence of different types, or from different sources, to a problem will change the calculated probabilities for the outcomes of the “reasoning” process. We’ve forgotten what he looked like, […]
25 Mar Generalization and Inference
What do you do when you encounter something completely new, such as a new flavor. Can you identify that it is a flavor and that it resembles some flavors you’ve encountered before? If you knew about bridges from experience, but had never seen a drawbridge, or a lift bridge or a covered bridge, would you be able […]
22 Mar Common Sense and Thresholds
Finding Thresholds Threshold conditions are boundaries between states, and they exist everywhere, affecting everything. From a computational perspective, thresholds are a valuable tool for limiting the problem space to within manageable limits. In other words, knowing where the edges are can help us computationally color inside the lines. How could we determine a threshold? Observing, […]
20 Mar Section 4 Intro – Perception and Cognition
Wha’cha Thinking? All the developers in the world could work forever to try to imitate brain functions, and even if they begin with a good understanding of the physiology of the brain and the microscopic mechanisms of electrical transmission between neurons, would have great difficulty passing a Turing test without some knowledge of perception, memory and cognition. Add Searle’s more demanding Chinese […]
19 Mar At the Edge of Possibility
Does the universe of probability have boundaries? Are there physical laws that control all phenomena, or is there a mystical, capricious random power out there that is not subject to the laws of physics? Is anything impossible? Physical laws are responsible for thresholds. Let us presume, for a moment, that probability is subject to one overriding […]
