+# TEAMS (Training ELECTRA Augmented with Multi-word Selection)
+
+**Note:** This project is working in progress and please stay tuned.
+
+TEAMS is a text encoder pre-training method that simultaneously learns a
+generator and a discriminator using multi-task learning. We propose a new
+pre-training task, multi-word selection, and combine it with previous
+pre-training tasks for efficient encoder pre-training. We also develop two
+techniques, attention-based task-specific heads and partial layer sharing,
+to further improve pre-training effectiveness.
+
+
+Our academic paper [[1]](#1) which describes TEAMS in detail can be found here:
