Prepare the data
Collect user-item interactions (completions, ratings or progress) and item metadata; handle duplicates and represent implicit/explicit signals clearly.
Recommend curricula for learners. Balance relevance and diversity.
Curriculum recommendation ranks learning items or learning paths for individual learners using behaviour and item metadata. Typical challenges include cold-start learners and items, popularity bias, coverage of required skills, and aligning recommendations with curriculum prerequisites and certification paths.

Curriculum recommendation ranks learning items or learning paths for individual learners using behaviour and item metadata. Typical challenges include cold-start learners and items, popularity bias, coverage of required skills, and aligning recommendations with curriculum prerequisites and certification paths.
A proposed application: help corporate training teams or education platforms suggest next learning modules for staff based on peers and item metadata. The supplied starter does not implement content-aware or production features; it is a small prototype for experimentation.
Collect user-item interactions (completions, ratings or progress) and item metadata; handle duplicates and represent implicit/explicit signals clearly.
Start with a user- or item-based collaborative filter to surface candidate curricula, and hold out interactions for offline ranking tests.
Use ranking metrics such as Precision@K, Recall@K and NDCG, and inspect failure modes like cold-start and popularity bias.
Add business rules, fallback logic, and a feedback loop that logs served recommendations and user responses for continuous improvement.
The supplied starter creates a tiny, hand-coded user-item ratings DataFrame, pivots it to a user-by-item matrix, computes cosine similarity between users, finds the nearest neighbour to a target user, and recommends that neighbour's unseen items ranked by their ratings.
matrix = ratings.pivot_table(index="user", columns="item", values="rating").fillna(0)
user_similarity = pd.DataFrame(
cosine_similarity(matrix),
index=matrix.index,
columns=matrix.index,
)The code uses a six-user, five-item synthetic rating table and no item metadata or contextual features. It demonstrates user-based collaborative filtering only and lacks evaluation on held-out data, cold-start handling, ranking metrics, business rules, experiment tracking or any production-serving interface.
A proposed extension is a hybrid system that combines collaborative filtering with content-based features (item metadata, skills tags and prerequisites), evaluates with Precision@K and NDCG on real experiment logs, and exposes recommendations through a small API with feedback capture.
This is a potential application pathway, not a delivered product. The supplied starter does not implement this service or validate it with real users.
