Abstract1; This paper presents our effort to the Audio/Visual+ Emotion Challenge (AV+EC2015), whose goal is to predict the continuous values of the emotion dimensions arousal and valence from audio, visual and physiology based modalities. The state of art classifier for dimensional recognition, long short term memory recurrent neural network (LSTM-RNN) is utilized. Except regular LSTM-RNN prediction architecture, two techniques are investigated for dimensional emotion recognition problem. The first one isε-insensitive loss is utilized as the loss function to optimize. Compared to squared loss function, which is the most popular loss function for dimension emotion recognition,  ε-insensitive loss is more robust for the label noises. The other one is temporal pooling among successive frames. This technique enables temporal modeling in the input features and increases the diversity of the features fed into prediction architectures. Experiments results show the efficiency of each key point of the proposed method and competitive results are obtained.
