<!-- gdoc-inlined -->
1. Periodicity
- Hierarchical Periodicity
- Ex., Seasonality
- Burstiness
- Ex., Hawkes Process
- Stationary vs. Non-Stationary Distributions
- Permanence / Option Structure
- Quantized
- Ex. hitting lights when predicting arrival time
- Autoregression / Autocovariance
- Feedback
- Positive Feedback
- Negative Feedback
- Length of feedback loops
- Synchronicity vs. Asynchronicity
- Discrete vs. Continuous
- Exponential Decay vs. Windowing
- Continuity vs. Discreteness
- Stability & Equilibrium
- Derivatives - change over time
- Asymmetry between past and future
- Exclusive ability to directly impact present
- Strong predictor of causality / anti-causality
- Examples
- Skewedness in Predicting Completion Time
- Say, for predicting arrival time - much more likely to be early in time
- Time in Decision Loops
- Nested (Hierarchical) Decision Loops
- Being within another’s decision loop
- Rates
- Information over time
- Distance over time
- Hierarchical Planning
- Compression over extended lengths of time
- Intensity (Value to smaller time window)
- Deadlines
- Time Culture / Pace
- Speed or Slowness of an environment or workplace
- Feedback (In the reward / punishment sense)
- Length of feedback loops
- Proxies for feedback to shorten length
A lot of these are about the value to slowness or quickness, it’s been hard to abstract well over time (though I suppose that ‘slow’ and ‘fast’ are abstractions about relative measures of time)
Properties
- Association with Causality
- Combinatorial explosion in complexity when ordering is introduced
Thoughts
-
Should I distinguish between temporal structure and sequential structure?
- Quantized, like hitting lights for predicting arrival time
- Making food in a kitchen (Tempo)
- Dancing (Rhythmic / Periodic)
- Option / Permanence - School choice, Tatoos, Relationships
