Random Walk Word2Vec
 Short truncated random walks are sentences in an
artificial language
 Random walk distance is known to be good features for
many problems
for example:
a. Recommendation
b. Search optimization
despite accuracy, gives the sense of serendipity
青花瓷 珊瑚海 我不配 給我一首歌的時間
黃金甲 珊瑚海 雙截棍 天地一鬥
Cold start ?
Learn the relationships
between laten factors
and audio signals
Future Directions
Hybrid of collaborative filtering and content based techniques
Trending/Popular within user segments
Optimizing for various metrics drive business goals
