Few–Shot Action Recognition
Valeti Likhitha Chowdary,  Nidadavolu Bhavya Sree Ratna,  Ankitha Lunavath,  Rajesh Kandakatla
The goal of few-shot action identification is to detect new action classes using only a few sets of training samples. The majority of available approaches use a meta-learning approach combined with episodic training. The few samples in a meta-training job are divided into support and query sets in each episode. The former is used to construct a classifier, which is subsequently assessed on the latter using a query-centered loss for updating the model. However, there are two key limitations, which are: a lack of data efficiency attributable to the query-centered only loss design and an inability to cope with outlying samples and inter-class distribution overlapping anomalies raised within the support set. We address these shortcomings in this study by introducing a new Prototype-centered Attentive Learning (PAL) model consisting of two revolutionary components. To make maximum use of the minimal training samples in each episode, a prototype-centered contrastive learning loss is introduced to enhance the traditional query-centered learning objective. Second, PAL incorporates a hybrid attentive learning method that can reduce the adverse effects of outliers while also promoting class separation.
