- Let the sequence of events be: x = [x_1, x_2, ..., x_N]
- d_j ∈ {-1, 0, +1} → direction of event (j)
- x_j → magnitude of event
- x_0 = 0 → base for differences
- Observed outcome: O_obs
| Variable | Description | Definition |
|----------|-------------|------------|
| x = [x1, x2, …, xN] | The ordered sequence of $NS events. | xi is the signed value (position/displacement) of event j. |
| x0 | Base value for the initial difference. | x0 = 0 (Explicitly set). |
| Δj | The fundamental difference between consecutive events. | Δj = xj - xj-1 (Calculated from j=1 to N) |
| dj | Direction of the transition/change. | d_j = Δj ∈ -1, 0, +1 |
Step 2: Linear, Nonlinear, Hybrid contributions
- Step 2: Define and Identify Multiple Configurations
- a. Segmentation: Identify M distinct segments (configurations) by finding optimal change points {tm} that minimize the fit error across the sequence x.
- This allows identification of any number of configurations.
- Formula (Change Point Detection): \[ \min_{(M, \tau_m)_{m=0}^{M}} \sum_{m=0}^{M} \cos f_t (x_{\tau_m}, x_{\tau_{m+1}}) + \text{Penalty}_{y_{complexity}}(M) \]
- b. Local Contributions: Calculate Linear (L_m), Nonlinear (NL_m), and Hybrid (H_m) contributions for each segment m (from tm to tm+1).
- Captures direct influence of magnitude and direction, bounded by magnitude sum
Nonlinear contribution (NL)
Local Linear contribution (Lm) Lm = \[ \frac{\sum{j \in \text{Segm}} |\Delta j| \gamma}{\sum{j \in \text{Segm}} |\Delta j| \gamma + \epsilon'} \]
Captures the direct influence of magnitude and direction for segment $m$, representing the smooth, underlying trend
- Captures interactions, abrupt changes, surprises
\[ H{x{\text{signed}}}^{\lambda} \]
captures how much direction-sensitive informational complexity is generated by the pattern of zeros, positive signals, and negative signals within a segment.
Step 3: Combine contributions
We want a hybrinear function (linear + nonlinear + interaction):
Step 3: Combine Local Contributions into a Hybrinear Function The predicted outcome (Fpredmulti) is the weighted sum of all local contributions, scaled by segment length.
\[ F_{pred_{multi}} = \sum_{m=0}^{M} \left( \frac{\text{Length } h_m}{N} \right) \cdot (\alpha \cdot L_m + \beta \cdot NL_m + \delta \cdot H_m) \]
\( \alpha, \beta, \delta \) = weighting coefficients for linear, nonlinear, hybrid contributions
Can be tuned depending on importance of each aspect
Step 4: Include outcome / latent emergence
Include Outcome / Latent Emergence Let latent emergence (LE_multi) be:
\[ LE{multi} = O{obs} - F{pred{multi}} \]
Ffinal = Fpredmulti + \eta \cdot LEmulti \( \eta \) = scaling factor for latent emergence influence
We can include emergence as modifier to adjust final rating:
\[ F{final} = F{pred} + \eta \cdot LE \]
- \( \eta \) = scaling factor for latent emergence influence
Step 5: Dominant direction contribution
Identify Multiple Dominant Configurations Identify the dominant contribution for each segment (configuration)
Dominance Score m= \( \alpha Z{Lm} + \beta Z{NLm} + \delta Z{Hm} + \gamma Y{LNLmZNLm} + \gamma Y{LHLmZHm} + \gamma Y{HNLmZHm} \)
| Term | Components | Effect Captured |
|------|------------|-----------------|
| \( \lambda \{LN\} \) | L and NL | Synergy or Conflict: If both \( Z{Lm} \) and \( Z{NLm} \) are high (positive), their product is large and positive. If \( \lambda \{LN\} \) is positive, it signifies that high L and high NL together create an impact greater than the sum of their individual effects (a synergistic or "hybrinear" effect). If \( \lambda \{LN\} \) is negative, it suggests a trade-off or conflicting relationship. |
| \( \lambda \{LH\} \) | L and H | The combined impact of Linear and Holistic components. |
| \( \lambda \{NH\} \) | NL and H | The combined impact of Non-Linear and Holistic components. |
Step 6: Full comprehensive formula
Lm = \( \sum_{j \in \text{Segm}} d_j \cdot x_j \sum_{j \in \text{Segm}} x_j + \epsilon \)
Δj = dj (xj - xj-1), x0 = 0
NLm = \( \sum{j \in \text{Segm}} |\Delta j| \sum{j \in \text{Segm}} |\Delta j| + \epsilon' \)
Hm = \( \tanh(|\text{Segm}|) \cdot \text{Count of Zeroes in Segm} + \epsilon \)
Fpredmulti = \( \sum{m=0}^{M} \left( \frac{\text{Length } m}{N} \right) \cdot (\alpha \cdot Lm + \beta \cdot NLm + \delta \cdot Hm) \)
LEmulti = \( O{obs} - F{predmulti} \)
Ffinal = \( F{predmulti} + \eta \cdot LEmulti \)
Dominant Contribution m = \( \text{argmax}(\alpha |L_m|, \beta |NL_m|, \delta |H_m|) \)
Step 7: Finalized Adaptive Emergence Metric / Objective Function
\[ J(C) = \frac{1}{\dot{\iota} C \dot{\nu}} \sum{i \in C} \left( \Delta Ei \right) \cdot S(1 - \alpha |Ai + \alpha Mi \dot{\iota} \right) \]
Step 7: Sequential Instability Index (ISeq)
ISeq=wAA+wBB+wCC|ISeq| = w_A A + w_B B + w_C C|ISeq=wAA+wBB+wCC
The components of sequential instability should be explicitly linked to the segmented hybrinear metrics:
- Magnitude Instability A:
- A=Var(Lm)A = Var(L_m)A=Var(Lm)
- Directional Instability B:
- B=mean(BDDI)=mean(1−cosθj)
where θj is derived from direction vectors based on djd_jdj.
- C=S+1C = \frac{S}{S + 1}
where S = number of sign changes in the direction sequence (d_j).
