+For challenge, with the concept of public/private score, we use meta parameters.
+```python
+_result_object =  {
+  "score": f1,
+  "score_secondary": log_loss_score,
+  "meta": {
+    "private_score": 0.0,
+    "private_score_secondary": 0.0
+  }
+}
+```
+
+Here the numbers in score & score_secondary will be visible to participants during the challenge, while "private_*" are hidden for them .
+Once the challenge is over, we can change it to "private_score" & "private_score_secondary" in Leaderboard settings.
