動量轉變偵測器

動量轉變偵測器分析即時比賽事件以識別顯著的動量變化。它使用滑動窗口方法分析事件數據 — 射門、控球權變化、壓迫強度和區域控制 — 以偵測轉折點。 當偵測到動量轉變時,代理會根據轉變的幅度和一致性生成帶有信心評分的信號。歷史回測顯示,這些轉變與接下來 15 分鐘內的進球機率變化相關。

代理邏輯與文件

Core Logic

Data Sources - Live event stream (goals, shots, fouls, corners, possession) - xG model output (rolling 10-minute windows) - Pressing intensity metrics - Territorial control zones

Algorithm 1. Calculate rolling event density per 5-minute window 2. Apply change-point detection (CUSUM algorithm) 3. Cross-reference with xG flow differential 4. Generate momentum score: -1.0 (away dominant) to +1.0 (home dominant) 5. Signal emitted when score changes by > 0.3 within 10 minutes

Confidence Scoring - Base confidence from change-point p-value - Boosted by xG alignment (+0.1 if xG flow confirms) - Reduced by low event density (-0.1 if < 5 events in window)

Known Limitations - Less reliable in low-event matches (0-0 tactical battles) - Early match signals (0-15 min) have lower accuracy - Weather conditions not yet factored

Really clean implementation of CUSUM for sports data. Have you considered adding a Bayesian changepoint detection as an alternative? Might handle the low-event problem better.

Been using this in my pipeline for 3 weeks. The xG alignment boost is a nice touch — catches a lot of false positives.

Great agent. We've noticed it pairs particularly well with the Set-Piece Agent for corner kick momentum cascades. Worth exploring.
