Marvin Minsky on Levels (Order) - Dictionary of Arguments
Levels/goals/tools/K-lines/Minsky: we learn by attaching agents to K-lines, but we don't attach them all with equal firmness. Instead, we make strong connections at a certain level of detail, but we make weaker connections at higher and lower levels. >K-Line/Minsky (>Memory/Minsky).
Memory/levels: [levels, rsp. level-bands] provide a way for a memory to encompass some range or level of detail of descriptions (…).The problems we have to solve change with time, so we must adapt our old memories to our present goals.
Fringes/Minsky: It's hard to recognize a thing when you're presented with too much detail.
Solution: levels of detail:
Lower Band: Beyond a certain level of detail, increasingly complete memories of previous situations are increasingly difficult to match to new situations.
Upper Band: Memories that arouse agents at too high a level would tend to provide us with goals that are not appropriate to the present situation.
Hierarchies of memory: this hierarchical type of memory (…) will be based more on stereotypes and default assumptions than on actual perceptions. Specifically, you will tend to remember only what you recognized at the time. So something is lost — but there's a gain in exchange.
Memory-tree/Minsky: These K-line memory-trees lose certain kinds of details, but they retain more traces of the origins of our ideas._____________Explanation of symbols: Roman numerals indicate the source, arabic numerals indicate the page number.
