  • Focused on NLP within the healthcare sector.
  • Worked with Lior during his tenure at MSK.
  • Co-authored "Mastering NLP from Foundations to Large Language Models."

The Journey to Writing "Mastering NLP from Foundations to Large Language Models"

How It Started

The idea originated from a conversation between Lior and the host, Ali Abdi, who recognized the need for an in-depth technical book on NLP. This was before the release of ChatGPT, making it a niche but necessary endeavor. The project took a turn when ChatGPT launched, making NLP a central focus for many and shifting the book's scope to be more inclusive of advanced topics while reducing the in-depth mathematical foundations.

Incorporating Practical Experiences

In addition to foundational theories, the book includes practical hands-on techniques and advanced topics like language models and multi-agent systems. This is aimed to cater to both theoretical and practical learners.

Why Mathematical Foundations Are Crucial

As explained by Meysam, understanding the mathematical principles behind NLP and machine learning algorithms is crucial. This knowledge allows for more effective debugging, optimizing algorithms, and ultimately being an expert rather than just a user of these technologies.

Why Are Large Language Models (LLMs) Becoming So Popular?

Both Lior and Meysam agree that the popularity of LLMs stems from their applicability across various fields. They provide practical examples, such as personal assistants being able to manage schedules and tasks, reducing the time spent on mundane activities. Meysam also mentions the role of transfer learning, which allows for fine-tuning LLMs with minimal training data.

Real-World Use Cases

The book covers a wide range of applications including:

  • Healthcare: NLP for extracting patient information, assisting in diagnostics, and predicting patient outcomes.
  • Multi-Agent Systems: These systems assign different roles to different LLMs, such as one for programming and another for quality assurance, leading to higher quality outputs and reducing errors.

Future of NLP and LLMs

Lior's Perspective

  • Personal Assistants: The evolution will see LLMs serving as personal extensions, optimizing work routines and decision-making processes.
  • Cost: Cost efficiency will be a major focus, impacting how LLM technology will be accessible and usable.

Meysam's Perspective

  • Personalized Education: LLMs will revolutionize personalized learning experiences.
  • Multimodal LLMs: These will handle more than one type of input, making them suitable for a broader range of applications.

Ethical Considerations

Key Points by Meysam

  • Bias in Data: Training data needs to be unbiased to ensure the LLM's outputs are fair.
  • Privacy Concerns: LLMs can retain and reveal training data, posing a risk of privacy breaches.
  • Misuse of AI: There are concerns about AI-generated content being misused.

Lior's Perspective

  • Human Oversight: Guardrails should be implemented to ensure compliance and ethical usage.
  • Regulations: Differing regulations across jurisdictions can affect how LLMs are utilized.
