* `train==[30.47060=16.64901 + 13.32211 + 0.49948]` records the loss of BPR loss for recommendation, BPR loss for knowledge graph embedding, and L2 regularization terms for both previous phases;
* `recall=[0.06590, 0.19621]` illustrates the `recall@20` and `recall@100` scores; analogously for precision, hit, and ndcg scores.

The final perfroamnce is shown as:
```
Best Iter=[95]@[166677.6] recall=[0.08820 0.12068 0.14174 0.15773 0.17082], precision=[0.03521 0.02661 0.02217 0.01939 0.01741], hit=[0.36111 0.46397 0.52597 0.56730 0.59930], ndcg=[0.13660 0.16881 0.19020 0.20689 0.22085]
```
where:
* `Best Iter=[95]@[166677.6]` shows that the best performance appears at the `95*10` epoch (since we show the training log every 10 epochs);
* `recall=[0.08820 0.12068 0.14174 0.15773 0.17082]` displays the final performance w.r.t. `recall@k`, where `k` spans from `20`, `40`, `60`, `80` to `100`.

## Some Points
Here I would like to clarify some points:
* The training and testing time costs might be different based on the running machines.
