I. Technical Principles: AI-Driven Paradigm Shift in Directed Evolution
EVOLVEbyAI integrates deep learning, Bayesian optimization, and active learning into a unified platform to revolutionize protein engineering through Design-Build-Test-Learn (DBTL) cycles. This approach addresses the inefficiencies of traditional directed evolution (random mutagenesis and high-throughput screening) with three key innovations:

- Transfer Learning for Multitasking: Pre-trained on UniRef50 and other databases, models adapt to specific tasks (thermal stability enhancement, substrate selectivity tuning) via fine-tuning .
II. Core Methodology: End-to-End Automation
Intelligent Mutant Library Generation

- Collaboration: Open-source platforms (e.g., mcp-server-kubernetes) and standardized protocols (MCP) foster interdisciplinary innovation .
As quantum computing and synthetic biology converge, EVOLVEbyAI is poised to power cell-to-industry biomanufacturing networks, redefining breakthroughs in medicine, energy, and materials science.

EVOLVEbyAI: Revolutionizing Intelligent Diagnosis and Treatment Through Evolutionary Optimization
(As of May 28, 2025)
I. Technical Principles: AI-Driven Evolutionary Optimization Reshaping Clinical Logic
EVOLVEbyAI integrates evolutionary algorithms (EA) with deep learning (DL) to build a multi-objective intelligent diagnosis and treatment system. Its framework comprises three innovative layers:
Gene Pool Mixing Evolutionary Algorithm (GOMEA)
Dynamically recombines biomarkers (genomic, proteomic, metabolic data) to identify optimal feature combinations, overcoming dimensionality challenges in traditional methods.

Few-Shot Active Learning Framework
Uses Gaussian Process Regression (GPR) to predict adaptive fitness landscapes from minimal clinical data (50–100 cases), reducing reliance on large annotated datasets.
For rare disease diagnosis, migration learning leverages UniRef50 protein function databases, achieving 89% diagnostic accuracy .
Dynamic Digital Twin Modeling
Integrates real-time multi-omics data, imaging features, and environmental parameters (e.g., medication history, lifestyle) to build personalized disease progression models for adaptive treatment optimization .
