Parameter Tuning : LiuYC === Procedure --- - Parameter set : __ALPHA-SLOPE-STD-A_DEC-R_MIN-TAU__ 0. Initial parameters trying all seneitivity tests. (Initial parameter set: 0.3-0.4-0.098-1.8-7-0.6 (random around average)) >A_DEC ~~~~~~~~~~~~~~~~~~~~ R_MIN >![](https://i.imgur.com/mzP2b1L.png =250x)![](https://i.imgur.com/WcnO2GL.png =250x) >SLOPE ~~~~~~~~~~~~~~~~~~~~ STD >![](https://i.imgur.com/JbL1Yoj.png =250x)![](https://i.imgur.com/lTyCK8V.png =250x) >ALPHA >![](https://i.imgur.com/kZvR61Q.png =250x) 1. Initial parameter set: 0.3-0.4-0.098-1.8-7-0.6 (random around average) > Tuninng A_DEC : (1.0, 8.7, 0.7) > ![](https://i.imgur.com/MO64Ffe.png =500x) 2. Change A_DEC to 3.8 (smallest of the overlapped) > Tunning R_MIN : (5.0, 16.0, 1.0) > ![](https://i.imgur.com/dbIlFwA.png =500x) 3. Change R_MIN to 12.0. Different result for when we want the best CAR value. R_MIN values smaller than 12.0 have higher CAR at around T-minus 2.5 while values larger than 12.0 at around T-minus 2.0 . > Tunning SLOPE : (0.1, 2.3, 0.2) > ![](https://i.imgur.com/BYV8jIh.png =500x) 4. Change SLOPE to 0.9. Values larger than 0.9 are overlapped. > Tunning STD : (0.01, 0.23, 0.02) > ![](https://i.imgur.com/L6YXvkW.png =500x) 5. Change STD to 0.11 which has the highest CAR at around 3 while not dropping it at around T-minus 2.0 . STD values from 0.01 to 0.07 have idinticle CAR curve. > Tuning ALPHA : (0.1, 2.3, 0.2) > ![](https://i.imgur.com/lkMroZt.png =500x) 5. Final parameter set : 0.3-0.9-0.11-3.8-12.0-0.6 6. Use the tunned parameters to try sensitivity test for all params again then compatr with those using initial parameter sets. >A_DEC (init) >![](https://i.imgur.com/mzP2b1L.png =500x) >A_DEC (tuned) >![](https://i.imgur.com/SzwvCa2.png =500x) >R_MIN (init) >![](https://i.imgur.com/WcnO2GL.png =500x) >R_MIN (tuned) >![](https://i.imgur.com/wLmrDPJ.png =500x) >SLOPE (init) >![](https://i.imgur.com/JbL1Yoj.png =500x) >SLOPE (tuned) >![](https://i.imgur.com/GwzZWzW.png =500x) >STD (init) >![](https://i.imgur.com/lTyCK8V.png =500x) >STD (tuned) >![](https://i.imgur.com/ku9ydMP.png =500x) >ALPHA (init) >![](https://i.imgur.com/kZvR61Q.png =500x) >ALPHA (tuned) >![](https://i.imgur.com/lgVNscT.png =500x)
