Entities and relationships VS the brainOctober 4, 2008
As I'm reading chapter 4 of
On Intelligence, the author makes the comment that "All memories are stored in the synaptic connections between neurons".
Immediately my mind wandered to the ideas of entities and relationships that I've been playing with these last few months: Is this statement about the brain analogous?
In a sense, I already knew that it was since I used this model for the very reason that it was analogous to nodes and edges, and ultimately, neurons/axons/synapses. But what suddenly struck me is that, since the brain uses neurons at different levels, so it is likely that it would be useful for what I'm working on to use the entity/relationship pattern at different levels and in different contexts.
What I'm getting at is that while an "entity" can represent a concrete idea such as "person", "dog", "run", etc., it might be as well suited to represent something at a completely different level of processing, such as how bright a certain pixel on the screen is, etc. These other "layers" are completely different areas of study, but this is an interesting idea to consider.
Exercise 20: Deriving properties of relationshipsOctober 2, 2008
SummaryIn addition to deriving property values and the existence of relationships, there are times we want to derive properties of relationships. For example:
"I have two sisters"
"I don't have a brother"
"How many siblings do I have?"
rule:
$1 is_a person
$1 has(count:$2) sister
$1 has(count:$3) brother
$count = # $2 + $3
-> $1 has(count:$count) sibling |
