We used two multimodal models for continuous valence-arousal recognition using visual, audio, and linguistic information. The first model is the same as we used in ABAW2 and ABAW3, which employs the leader-follower attention. The second model has the same architecture for spatial and temporal encoding. As for the fusion block, it employs a compact and straightforward channel attention, borrowed from the End2You toolkit. Unlike our previous attempts that use Vggish feature directly as the audio feature, this time we feed the pre-trained VGG model using logmel-spectrogram and finetune it during the training. To make full use of the data and alleviate over-fitting, cross-validation is carried out. The code is available at https://github.com/sucv/ABAW3.

翻译：我们使用两种多模态模型，利用视觉、音频和语言信息进行连续效价-唤醒度识别。第一个模型与我们在ABAW2和ABAW3中使用的模型相同，采用领导者-跟随者注意力机制。第二个模型在空间和时间编码上采用相同架构。至于融合模块，它采用紧凑且直接的通道注意力机制，该机制借鉴自End2You工具包。与之前直接使用Vggish特征作为音频特征的尝试不同，本次我们使用对数梅尔频谱图输入预训练VGG模型，并在训练过程中对其进行微调。为充分利用数据并缓解过拟合问题，我们执行了交叉验证。代码开源地址：https://github.com/sucv/ABAW3
