# YRTV Player Capability Model (6-Dimension System)
|
||
|
|
|
||
|
|
This document outlines the calculation principles and formulas for the 6-dimensional player capability model used in the YRTV platform.
|
||
|
|
|
||
|
|
## Overview
|
||
|
|
|
||
|
|
The model evaluates players across 6 key dimensions:
|
||
|
|
1. **BAT (Battle Power)**: Aim and direct combat ability.
|
||
|
|
2. **PTL (Pistol)**: Performance in pistol rounds.
|
||
|
|
3. **HPS (High Pressure)**: Performance in clutch and high-stakes situations.
|
||
|
|
4. **SIDE (Side Proficiency)**: T vs CT side performance balance and rating.
|
||
|
|
5. **UTIL (Utility)**: Usage and effectiveness of grenades/utility.
|
||
|
|
6. **STA (Stability)**: Consistency and endurance over matches/time.
|
||
|
|
|
||
|
|
Each dimension score is normalized to a 0-100 scale using min-max normalization against the player pool (with outlier clipping at 5th/95th percentiles).

## Calculation Process (ETL)
|
||
|
|
1. **L2 Aggregation**: Raw match data is aggregated into `fact_match_players` (L2).
|
||
|
|
2. **Feature Extraction**: Complex features (e.g., Pistol KD, Side Rating) are calculated per player.
|
||
|
|
3. **Normalization**: Each feature is scaled to 0-100 based on population distribution.
|
||
|
|
4. **Weighted Sum**: Dimension scores are calculated using the weights above.
|
||
|
|
5. **Radar Chart**: Final scores are displayed on the 6-axis radar chart in the player profile.
