week02 Text Classification
- Lecture: Text classification: introduction and datasets. General framework: feature extractor + classifier. Classical approaches: Naive Bayes, MaxEnt (Logistic Regression), SVM. Neural Networks: General View, Convolutional Models, Recurrent Models. Practical Tips: Data Augmentation. Analysis and Interpretability. Interactive lecture materials and more.
- Seminar: Text classification with convolutional NNs.
- Homework: Statistical & neural text classification.

week03 Language Modeling
- Lecture: Language Modeling: what does it mean? Left-to-right framework. N-gram language models. Neural Language Models: General View, Recurrent Models, Convolutional Models. Evaluation. Practical Tips: Weight Tying. Analysis and Interpretability. Interactive lecture materials and more.
- Seminar: Build a N-gram language model from scratch
- Homework: Neural LMs & smoothing in count-based models.
-
week04 Seq2seq and Attention
- Lecture: Seq2seq Basics: Encoder-Decoder framework, Training, Simple Models, Inference (e.g., beam search). Attention: general, score functions, models. Transformer: self-attention, masked self-attention, multi-head attention; model architecture. Subword Segmentation (BPE). Analysis and Interpretability: functions of attention heads; probing for linguistic structure. Interactive lecture materials and more.
- Seminar: Basic sequence to sequence model
- Homework: Machine translation with attention

week05 Transfer Learning
- Lecture: What is Transfer Learning? Great idea 1: From Words to Words-in-Context (CoVe, ELMo). Great idea 2: From Replacing Embeddings to Replacing Models (GPT, BERT). (A Bit of) Adaptors. Analysis and Interpretability. Interactive lecture materials and more.
-
week06 (TBU) LLMs and Prompting
- Lecture: Scaling laws. Emergent abilities. Prompting (aka "in-context learning"): techiques that work; questioning whether model "understands" prompts. Hypotheses for why and how in-context learning works.
