Query: Seven Basic Expression Recognition Using ResNet-18   We propose to use a ResNet-18 architecture that was pre-trained on the FER+
dataset for tackling the problem of affective behavior analysis in-the-wild
(ABAW) for classification of the seven basic expressions, namely, neutral,
anger, disgust, fear, happiness, sadness and surprise. As part of the second
workshop and competition on affective behavior analysis in-the-wild (ABAW2), a
database consisting of 564 videos with around 2.8M frames is provided along
with labels for these seven basic expressions. We resampled the dataset to
counter class-imbalances by under-sampling the over-represented classes and
over-sampling the under-represented classes along with class-wise weights. To
avoid overfitting we performed data-augmentation and used L2 regularisation.
Our classifier reaches an ABAW2 score of 0.4 and therefore exceeds the baseline
results provided by the hosts of the competition.
