Version History

March 2026 — Current

Version 0.3 — ML Engine

Launch v0.3 Dashboard →

Complete engine rebuild powered by Random Forest feature importance. Data extracted from 90+ peer-reviewed papers, 51 real cleaning technologies ranked via 0-1 normalized 5-variable FoM with median imputation.

\[ FoM_{v0.3} = \frac{(AI\_Level)^{\alpha} \times (Automation)^{\beta} \times (Lifetime)^{\gamma}}{(OPEX)^{\delta} \times (Scratch)^{\epsilon}} \]
  • Random Forest selected Top 5 features from 25-column dataset
  • Median imputation for missing values — all rows ranked
  • Strict 0-1 normalization (÷ column max) eliminates scale bias
  • Review/Survey papers filtered out — only physical technologies
  • Interactive Chart.js bar chart with gold/silver/bronze ranking

Version 0.2 (Legacy)

Launch v0.2 Interactive Dashboard →

Shifted to a robust, strict multiplicative formula architecture based on Dr. Sameh's system engineering feedback. Includes parametric exponents allowing users to dynamically adjust output priorities.

\[ FoM_{v0.2} = \frac{(Recovery)^{\alpha} \times (Lifetime)^{\beta}}{(Water)^{\gamma} \times (CAPEX)^{\delta}} \]
  • Renamed core tracker from "Efficiency" to "Recovery Percentage"
  • Introduced Lifetime and CAPEX parameters for commercial viability
  • Implemented 1-100 feature scaling mapping to handle math variations safely

Version 0.1

The original prototype developed during Semester 1. Focused heavily on additive logic to test and parse extracted literature components.

\[ FoM_{v0.1} = \eta + S \]
  • Where \(\eta\) represented basic energy restored
  • Where \(S\) represented a broad sustainability additive score
  • Deprecated due to mathematical weight imbalance (1 Unit of Water != 1% Efficiency)
