Advanced Topic 37 of 51 AI & Machine Learning
Transformers
Attention-based architecture underpinning modern language models.
How it works
Transformers stack self-attention and feed-forward layers with residual connections, layer norm and positional encodings, processing all tokens in parallel; they scale well with data and compute.
Where it is used
GPT, BERT, vision transformers.
Common pitfall
Large memory needs and quadratic attention.
Where it fits in the course
Transformers is topic 37 of 51 in AI & Machine Learning, rated Advanced. It follows Attention Mechanism. The next topic is Large Language Models.
