A Syllabus Stuck in the Past: The Comedy of Teaching Large Language Models

 A Syllabus Stuck in the Past: The Comedy of Teaching Large Language Models  


There’s something tragically comic about a syllabus that attempts to teach large language models (LLMs) but reads like a hodgepodge of buzzwords thrown together by someone who stopped reading AI papers three years ago. At first glance, it looks ambitious: it promises to cover everything from transformers and attention mechanisms to recent innovations like Stable Diffusion and Mixture-of-Experts. But a closer look reveals an astonishing lack of depth, coherence, and—most unforgivably—mathematics.

 The Mirage of Understanding  

The syllabus starts with a noble-sounding goal: to help students “understand the principles and challenges of LLMs.” But instead of diving into the gritty details of why transformers revolutionized deep learning or how attention mechanisms work mathematically, it settles for vague generalities. Concepts like "probabilistic foundations" are dangled in front of the students with no attempt to dive into the linear algebra or optimization techniques that actually power these models. It's like asking someone to explain quantum physics without ever mentioning wave functions.  


 Transformers and Attention—Buzzwords Over Substance  

Transformers are name-dropped as though their mere mention will make students smarter, but there’s no indication of an effort to explain how multi-head attention works or why positional encodings are crucial for sequence modeling. How can we claim to teach "architectures and components" when the math behind scaling laws or gradient descent gets no airtime? Instead, we get a passing mention of Mixture-of-Experts and retrieval-based models, topics that would stump even experienced ML practitioners if reduced to 14 hours of vague PowerPoint slides.


 Applications: A 2010s Nostalgia Tour  

The section on LLM applications is particularly laughable. It boasts about teaching tasks like sentiment analysis and named entity recognition—problems that were solved years ago with far simpler methods. Meanwhile, transformative advancements like few-shot and zero-shot learning are ignored, and concepts like prompt engineering or instruction tuning—essential for real-world applications—are conspicuously absent. And let’s not even start on the supposed “deep dive” into code generation, which will likely avoid actual tools like Codex or advanced GPT-based programming assistants.


 Recent Innovations: All Sizzle, No Steak  

Ah, the pièce de résistance: “recent innovations.” Here we see an eclectic collection of buzzwords—“Stable Diffusion,” “replacing attention layers,” and “Vision Transformers.” But where’s the substance? Where’s the discussion of RLHF (reinforcement learning with human feedback), scaling laws, or multimodal models like GPT-4 or GPT-V? Even when ethics and security are mentioned, they feel like an afterthought rather than an integrated part of the curriculum.  


HuggingFace Isn’t a Framework  

And then there’s the elephant in the room: HuggingFace, a platform that has become synonymous with democratizing NLP, is casually described as a "framework." Calling HuggingFace a framework is like calling Amazon a “retail API.” This isn’t just a semantic issue—it reflects a fundamental misunderstanding of the tools students are expected to master. HuggingFace is a vast ecosystem, not a rigid framework like TensorFlow or PyTorch. Mislabeling it betrays a lack of familiarity with the landscape of modern machine learning.  


 The Textbook Mentality  

It’s painfully clear that this syllabus was designed with the mindset of a dusty textbook author, trying to simplify a field that thrives on complexity and rapid evolution. LLMs aren’t static artifacts to be studied; they’re dynamic systems, constantly evolving as researchers refine architectures, scale models, and push boundaries. Attempting to teach them without a grounding in math, cutting-edge research, or hands-on coding is like teaching rocket science using a paper airplane.


 What Students Deserve  

This syllabus isn’t just outdated—it’s a disservice to students who deserve a real education in LLMs. A modern course should start with the math: attention mechanisms, gradient descent, and transformer architectures. It should include rigorous coding projects, using real-world tools like HuggingFace’s Transformers library (yes, library, not framework). And most importantly, it should focus on where the field is going, not just where it’s been.  


Until then, this syllabus remains a case study in how not to teach one of the most exciting fyields in AI. Let’s hope future iterations embrace the rigor, depth, and forward-thinking approach that LLMs truly deserve.


Cherry on the cake the text book by Ashish does not exist.  Looks like this syllabus came out of a hallucinating Chat bot
