Critical Hyperparameters for Optimal Performance
An ablation study reveals the critical impact of Hi-MetaCap's core hyperparameters on its overall performance. Optimizing the weights for unsupervised loss terms (λx, λy) and the smoothing coefficient (α) for the Mean Teacher ensemble proved crucial. The study validated that even small adjustments to these parameters significantly influence the model's ability to learn from non-paired data and refine its captioning capabilities.

The ablation study confirmed optimal performance when λx = 0.1 and λy = 1, driving effective utilization of non-paired images and captions. A smoothing coefficient (α) of 0.99 for the Mean Teacher further reinforced the generation of robust pseudo captions, underscoring the importance of these parameters for efficient few-shot learning. The latent feature initialization standard deviation (σ) of 0.1 also played a key role in the pseudo feature generation process.
Advancing AI for Low-Resource Languages
Hi-MetaCap: A Breakthrough in Resource-Efficient Image Captioning
Challenge: Generating high-quality image captions for low-resource languages like Hindi traditionally demands massive paired image-caption datasets. These datasets are exceptionally costly and time-consuming to create, severely limiting the practical application of AI in such linguistic contexts.
Solution: Hi-MetaCap introduces a novel meta-learning framework that strategically combines an ensemble of Object Relational Transformers (ORT) with an advanced self-distillation strategy. This enables the model to effectively learn from a mere 1% of paired data, complemented by vast quantities of readily available non-paired images and captions.
Impact: This innovative approach fundamentally reduces data dependency, making high-quality Hindi image captioning feasible and scalable. By achieving state-of-the-art performance (e.g., up to 48% CIDEr-D improvement over leading baselines like BLIP) with minimal labeled data, Hi-MetaCap sets a new precedent for efficient and generalized AI-driven language processing, opening doors for practical enterprise applications in previously underserved linguistic markets.
