• Abstract: Cross-Modal Retrieval (CMR) is an important research topic across multimodal computing and information retrieval, which takes one type of data as the query to retrieve relevant data of another type, and has been widely used in many real-world applications. Recently, the vision-language pre-trained model represented by CLIP has demonstrated its superiority of learning visual and textual representations and its impressive performance on various vision and language related tasks. Although CLIP as well as the previous pre-trained models have shown great performance improvement in unsupervised CMR, the performance and impact of these pre-trained models on supervised CMR were rarely explored due to the lack of multimodal class-level associations. In this paper, we take CLIP as the current representative vision-language pre-trained model to conduct a comprehensive empirical study and provide insights on its performance and impact on supervised CMR. To this end, we first propose a novel model CLIP4CMR (\textbf{CLIP For} supervised \textbf{C}ross-\textbf{M}odal \textbf{R}etrieval) that employs pre-trained CLIP as backbone network to perform supervised CMR. We then revisit the existing loss function design in CMR, including the most common pair-wise losses, class-wise losses and hybrid ones, and provide insights on applying CLIP. Moreover, we investigate several concerned issues in supervised CMR and provide new perspectives for this field via CLIP4CMR, including the robustness to modality imbalance and the sensitivity to hyper-parameters. Extensive experimental results show that the CLIP4CMR achieves SOTA results with significant improvements on the benchmark datasets Wikipedia, NUS-WIDE, Pascal-Sentence and XmediaNet.

  Multi-task learning (MTL) aims to improve the generalization performance of a model on multiple related tasks by training it simultaneously on those tasks. Continual learning (CL) involves adapting to new sequentially arriving tasks over time without forgetting the previously acquired knowledge. We develop theoretical results describing the effect of various system parameters on the model's performance in an MTL setup. Our results reveal the impact of buffer size and model capacity on the forgetting rate in a CL setup and help shed light on some of the state-of-the-art CL methods.

  Continual learning (CL) has garnered significant attention because of its ability to adapt to new tasks that arrive over time. Catastrophic forgetting (of old tasks) has been identified as a major issue in CL, as the model adapts to new tasks. MoE model has recently been shown to effectively mitigate catastrophic forgetting in CL, by employing a gating network.
