Abstract: 此篇論文中,我們提出了一種在線上音樂播放中使用的動態權重機
制。基於隱性因子模型之假設,使用者、歌曲、歌手皆是由一組隱性
空間中的向量表示。給定一使用者以及他的近期播放紀錄,即可判斷
他目前的興趣是傾向近期偏好或是長期偏好。同其他隱性因子模型,
此機制可在不使用內容資料的情形下訓練。這在使用網路播放紀錄當
做資料庫時是一個利基,因內容資料相對較難取得。在數個 last.fm 資
料集上的實驗結果顯示此方法確實有效。

In this paper, we propose a dynamic weight tuning scheme for online mu-
sic recommendation. Based on a latent factor model, songs, artists, and users
are mapped into a latent space. Then, given each user’s recent songs we can
determine his current interest for music, which either similar to his past be-
havior or more like recent ones. Like latent factor based models, this scheme
can be trained without content information, which is a benefit when adopting
internet radios as data source. Experimental results on the last.fm collections
show that our proposed method is effective.
