Technical Expertise
Integer Programming
Integer Programming (IP) is a powerful mathematical optimization technique that Warren has applied extensively throughout his career to solve complex business problems. Unlike continuous optimization, integer programming deals with decision variables that must take integer values, making it ideal for many real-world scenarios.
Applications
- Production planning and scheduling
- Resource allocation and workforce planning
- Re-balancing assets
- Vehicle routing and logistics optimization
Modeling
- Open-source and commercial solvers
- Open-source and commercial modeling languages
- Parameter tuning
- Python-based modeling
Warren has implemented integer programming solutions that have generated millions in cost savings and revenue optimization for Fortune 500 companies. His approach combines theoretical rigor with practical implementation, ensuring solutions that are both mathematically sound and business-relevant.
Large Language Models (LLMs)
Large Language Models (LLMs) represent the cutting edge of artificial intelligence, and Warren has been at the forefront of their application in business contexts. These powerful models have transformed how businesses interact with data, customers, and information systems.
Business Applications
- Intelligent customer service automation
- Content generation and summarization
- Knowledge management and information retrieval
- Data analysis and insight generation
- Process automation and workflow enhancement
Implementation Expertise
- Application for specific business domains
- Prompt engineering and optimization
- Retrieval-augmented generation (RAG) systems
- Responsible AI implementation and governance
- Integration with existing business systems
Warren's approach to LLMs goes beyond the hype, focusing on practical, value-driven implementations that deliver measurable business results. He has helped organizations navigate the complexities of LLM deployment, from model selection and fine-tuning to integration and governance, ensuring solutions that are both powerful and responsible.
Machine Learning
