我有一个 user's “味觉”向量：
+------+--------------------+|userId| scaledFeatures|+------+--------------------+| 18|[0.0,0.0,0.0,0.0,...|| 65|[0.0,0.0023910733...|| 96|[0.0,0.0,0.005268...|| 121|[0.0,0.0021253985...|| 129|[0.0,0.0029224229...|+------+--------------------+
以及 movie's 内容向量：
+-------+--------------------+|movieId| scaledFeatures|+-------+--------------------+| 1|[1.0,0.0,0.0,0.0,...|| 2|[1.0,0.0,0.0,0.0,...|| 3|[0.0,0.0,0.0,0.0,...|| 4|[0.0,0.0,0.0,0.0,...|| 5|[0.0,0.0,0.0,0.0,...|+-------+--------------------+
如何服用 user's 味觉矢量 userId 与…相乘 movie's pyspark中的内容表？所以我可以通过 movieId ?
