Domain Adaptation Papers Guide

Overview

Domain adaptation addresses the problem of training models on one data distribution (source domain) and deploying them on a different distribution (target domain). This curated collection covers the full spectrum — from unsupervised domain adaptation (UDA) and domain generalization to partial, open-set, and source-free adaptation. Organized by methodology and application area with regularly updated paper lists.

Taxonomy of Methods

Domain Adaptation
├── Unsupervised DA (UDA)
│   ├── Discrepancy-based (MMD, CORAL, CDD)
│   ├── Adversarial-based (DANN, ADDA, CDAN)
│   ├── Reconstruction-based (DRCN, DSN)
│   └── Self-training (SHOT, CBST)
├── Semi-supervised DA
├── Source-free DA (no source data at adaptation time)
├── Partial DA (target has subset of source classes)
├── Open-set DA (target has unknown classes)
├── Universal DA (no prior on label set relationship)
├── Multi-source DA
├── Domain Generalization (no target data at all)
└── Test-time Adaptation (adapt at inference)

Application Areas

Reading Roadmap

### Beginner Path
1. "A Survey on Transfer Learning" (Pan & Yang, 2010)
2. "Domain Adaptation for Object Recognition" (Saenko et al., 2010)
3. "Deep Domain Confusion" (Tzeng et al., 2014)
4. DANN paper (Ganin et al., 2016)

### Intermediate Path
5. CDAN (Long et al., 2018)
6. MCD (Saito et al., 2018)
7. "Moment Matching for Multi-Source DA" (Peng et al., 2019)

### Advanced Path
8. SHOT (Liang et al., 2020) — source-free
9. TENT (Wang et al., 2021) — test-time
10. "Benchmarking DA on Language" (Ramponi & Plank, 2020)

Use Cases

1. Literature survey: Map the DA research landscape
2. Method selection: Choose appropriate DA technique for your task
3. Benchmark comparison: Compare methods on standard datasets
4. Research gaps: Identify under-explored DA settings
5. Course material: Teach transfer learning and DA
