% =========================================== % 09_validation.tex — CORRECTED TABLE SEQUENCE % =========================================== \section{Validation} This section presents representative validation results demonstrating the correctness, stability, performance characteristics, and generality of the adaptive virtual machine architecture described herein. The results were obtained through controlled experimental procedures, including factorial design-space exploration, waveform-based stress testing, adaptive-versus-static comparisons, and convergence analysis. \subsection{Design Space Exploration} The system was evaluated across a comprehensive design space consisting of multiple feedback–loop configurations. Static configurations were tested across a multi-factor experimental grid to identify optimal and suboptimal operating points. Results show that: \begin{itemize} \item performance and stability vary widely among static configurations; \item the top-performing static configurations occupy narrow regions of the design space; \item the adaptive system consistently matches or exceeds the best static configurations; \item and the static-performance distribution substantiates the need for autonomous mode selection. \end{itemize} % TABLE 1 — ANOVA Main Effects \begin{table}[h] \centering {\small \setlength{\tabcolsep}{8pt} \renewcommand{\arraystretch}{1.2} \begin{tabular}{rrrrrl} \toprule Df & Sum Sq & Mean Sq & F value & Pr($>$F) & Factor \\ \midrule 1 & $7.42\times 10^{16}$ & $7.42\times 10^{16}$ & $1.15\times 10^{3}$ & $3.75\times 10^{-249}$ & L1\_heat\_tracking \\ 1 & $4.37\times 10^{14}$ & $4.37\times 10^{14}$ & 6.79 & 0.00916 & L2\_rolling\_window \\ 1 & $1.33\times 10^{15}$ & $1.33\times 10^{15}$ & 20.7 & $5.31\times 10^{-6}$ & L3\_linear\_decay \\ 1 & $3\times 10^{18}$ & $3\times 10^{18}$ & $4.66\times 10^{4}$ & 0 & L4\_pipelining\_metrics \\ 1 & $1.54\times 10^{14}$ & $1.54\times 10^{14}$ & 2.39 & 0.122 & L5\_window\_inference \\ 1 & $4.75\times 10^{13}$ & $4.75\times 10^{13}$ & 0.738 & 0.39 & L6\_decay\_inference \\ 1 & $5.94\times 10^{13}$ & $5.94\times 10^{13}$ & 0.923 & 0.337 & L7\_adaptive\_heartrate \\ 38392 & $2.47\times 10^{18}$ & $6.44\times 10^{13}$ & --- & --- & Residuals \\ \bottomrule \end{tabular}} \caption{TABLE 1 — ANOVA results for main effects in the full factorial design.} \label{tab:anova_main_effects} \end{table} % TABLE 2 — Top 5% Static Configurations \begin{table}[h] \centering {\small \setlength{\tabcolsep}{6pt} \renewcommand{\arraystretch}{1.2} \begin{tabular}{lrrrr} \toprule config & n & mean\_ns & cv\_pct & rank \\ \midrule 0100011 & 300 & $3.16\times 10^{7}$ & 15.1 & 1 \\ 0000000 & 300 & $3.17\times 10^{7}$ & 17.3 & 2 \\ 0010111 & 300 & $3.17\times 10^{7}$ & 14.8 & 3 \\ 0000101 & 300 & $3.18\times 10^{7}$ & 16.5 & 4 \\ 0000011 & 300 & $3.18\times 10^{7}$ & 16.0 & 5 \\ 0110111 & 300 & $3.19\times 10^{7}$ & 17.5 & 6 \\ 0010001 & 300 & $3.19\times 10^{7}$ & 15.3 & 7 \\ \bottomrule \end{tabular}} \caption{TABLE 2 — Top 5\% static configurations ranked by performance and variance.} \label{tab:top_static_configs} \end{table} \newpage \subsection{Runoff Validation of Candidate Modes} Following design-space exploration, the top-performing static configurations were subjected to head-to-head validation to identify the single best static baseline for comparison against the adaptive system.

Each workload family represents a different execution pattern: stable, diverse, temporal, transition, and volatile. Results demonstrate that: \begin{itemize} \item mode selection converges rapidly (mean 1 switch per run); \item execution predominantly settles in mode 1 (79\% occupancy); \item mode distribution is consistent across workload families; \item the system exhibits deterministic mode-selection behavior. \end{itemize} % TABLE 4 — L8 Mode Usage \begin{table}[h] \centering {\small \setlength{\tabcolsep}{6pt} \renewcommand{\arraystretch}{1.2} \begin{tabular}{lrrrrrr} \toprule workload\_type & n & mean\_switches & mode0 & mode1 & mode2 & mode3 \\ \midrule DIVERSE & 30 & 1 & 19.3 & 79.1 & 1.45 & 0.193 \\ STABLE & 30 & 1 & 19.3 & 79.1 & 1.45 & 0.193 \\ TEMPORAL & 30 & 1 & 19.3 & 79.1 & 1.45 & 0.193 \\ TRANSITION & 30 & 1 & 19.3 & 79.1 & 1.45 & 0.193 \\ VOLATILE & 30 & 1 & 19.3 & 79.1 & 1.45 & 0.193 \\ \bottomrule \end{tabular}} \caption{TABLE 4 — Mode usage statistics for the L8 Jacquard Mode Selector.} \label{tab:l8_mode_usage} \end{table} \subsection{Waveform Validation (Shape-Invariant Behavior)} To verify shape-invariance, the system was subjected to controlled waveform stressors designed to produce time-varying execution patterns.
