Pragmatic Roadmap mo le Fa'aaogaina o le Generate-and-Rank AI
Ina ia manuia le tuʻufaʻatasia o auala faʻatupu-ma-tulaga AI ile suʻesuʻeina peptide e aunoa ma le pa'ū i mailei sui, R&D ta'ita'i e tatau ona fa'atino le fa'ata'ita'iga o le fa'atinoga o la'asaga e lima:
[ Step 1: Establish Multi-Objective Proxy Pipeline ]
└── Define composite reward functions incorporating affinity, solubility, pLDDT & toxicity.
[ Step 2: Implement On-Policy Distillation & RL ]
└── Freeze pretrained PLM/Diffusion backbones; train LoRA adapters with KL penalties.
[ Step 3: Launch Closed-Loop Active Learning Rollouts ]
└── Deploy uncertainty-aware batch selection; ingest both active hits & synthetic failures.
[ Step 4: Mandate Orthogonal Wet-Lab Assay Matrix ]
└── Validate candidates across SPR/BLI, CD, DLS, and serum stability layers.
[ Step 5: Secure High-Purity Synthesis & Governance ]
└── Partner with Class 100 cleanroom synthesis CDMOs; enforce data lineage & CoA tracking.
