안녕하세요 선생님! 질문이 있습니다. 저는 Graph attention Network (Layer 3개)를 통과할 때마다 얻어지는 attention map을 저장해놓고, (npy) 이를 clustering하고 있는데요, attention map을 flatten한 뒤 KMeans를 활용하고 있습니다. 이때 실루엣 스코어가 k를 늘려나감에 따라서 계속 올라간다면, 이상한 현상이라고 봐야할까요?? 이때 저는 cluster label은 가지고 있지 않아요. Davis bouldin이나 Calinski harabasz도 같이 보고 있는데, 그리고 elbow method로도요,, 그런데 이상하게 실루엣 스코어 결과 k를 50에 가깝게 내놓게 되고 실제로 plot을 그려보면 saturation을 하지 않고 계속 k가 늘어남에 따라서 실루엣 스코어가 늘어난다면 이상한 현상이라고 봐야할까요?? 감사합니다.
