• Customer Segmentation Customer Segmentation은 고객을 행동·가치·선호의 유사성으로 유한개 세그먼트로 분할하는 비지도(unsupervised) 과제다. 흔히 잠재요인 분해 후 군집화: 행동 피처 → NMF(비음수 parts-based 분해) → factor score → K-Means → 세그먼트.
• Customer Segmentation & Causal Targeting — An Applied Case Study An end-to-end applied case study on the public Dunnhumby dataset — NMF latent factors and K-Means segmentation feeding meta-learner / Causal Forest HTE and an OPE-validated optimal targeting policy, with a candid look at positivity violation and counter-intuitive "sleeping dog" segments.
• Dunnhumby — Track 1: Latent-Factor Customer Segmentation NMF latent factors (92.44% explained variance) + K-Means yield 7 stable behavioral segments (Bootstrap ARI 0.77) with per-segment marketing actions. Illustrative case study on the public Dunnhumby retail dataset.
