The paper describes the best performing system for the SemEval-2018 Affect in Tweets (English) sub-tasks.The system focuses on the ordinal classification and regression sub-tasks for valence and emotion.For ordinal classification valence is classified into 7 different classes ranging from -3 to 3 whereas emotion is classified into 4 different classes 0 to 3 separately for each emotion namely anger, fear, joy and sadness.The regression sub-tasks estimate the intensity of valence and each emotion.The system performs domain adaptation of 4 different models and creates an ensemble to give the final prediction.The proposed system achieved 1 st position out of 75 teams which participated in the fore-mentioned subtasks.We outperform the baseline model by margins ranging from 49.2% to 76.4%, thus, pushing the state-of-the-art significantly.
