BART + Speaker-Aware Fine-tuning
Method
Speaker-Aware Function에 Speaker Token들의 Encoder Representation을 전달
Speaker Tokens : Turn에서 '' 다음 Token부터 ':' 이전 Token까지를 Speaker Token으로 간주하고 Mean Pooling
Positivie Sample : 기준 Speaker와 같은 Speaker Token들의 Encoder Representation
Negativie Sample : 기준 Speaker와 다른 Speaker Token들의 Encoder Representation
Contrastive Learning을 통해 Positive Samples와 Negative Samples의 Representation을 각각 비슷해지도록 학습

BART + Topic-Aware Fine-tuning
Method
Encoder로부터 나온 Encoder Representation 중에서 utterance token들의 Encoder Representation Mean Pooling 값을 계산
Topic-Aware Function에 Utterance Tokens의 Encoder Representation Mean Pooling을 전달
Kmeans Algorithm으로 각 Utterance Token들의 Topic을 Clustering으로 예측(# of Cluster : 2)
각 Cluster들의 Centeroid와 같은 Cluster의 표현과의 L2 Distance는 Positivie, 다른 Cluster의 표현과의 L2 Distance는 Negative로 추출
Contrastive Learning을 통해 Positive Samples와 Negative Samples의 Representation을 각각 비슷해지도록 학습
