Visual Question Answering With Multi Hop Reasoning

via “visual question answering with spatial reasoning”

Tiny vision-language model for edge devices.

Unique: Implements region encoding subsystem that maps pixel-level coordinates to semantic embeddings, enabling spatial reasoning without post-hoc bounding box detection; uses transformer cross-attention between vision and text embeddings to ground language generation in visual features, avoiding separate vision-text alignment modules.

vs others: Faster and more memory-efficient than BLIP-2 or LLaVA for VQA tasks due to smaller parameter count; maintains spatial reasoning capabilities that pure image captioning models lack.

via “visual question answering with instruction-following”

Meta's multimodal 11B model with text and vision.

Unique: Instruction-tuned specifically for VQA tasks on a compact 11B parameter model, enabling efficient question-answering without the 34B+ parameter overhead of alternatives like LLaVA. Maintains full 128K context for multi-turn conversations where image context persists across multiple questions.

vs others: Faster inference and lower memory footprint than larger VQA models while maintaining instruction-following quality through supervised fine-tuning on curated VQA datasets.

via “multi-hop reasoning evaluation across document sections”

8.3K financial reasoning questions over real S&P 500 earnings reports.

Unique: Embeds multi-hop reasoning requirements within authentic financial documents where hops correspond to real relationships between financial statement sections, rather than synthetic reasoning chains. This tests whether models understand domain structure, not just generic multi-hop patterns.

vs others: More realistic than synthetic multi-hop datasets (HotpotQA, 2WikiMultiHopQA) because reasoning hops follow actual financial relationships, but less controlled because document structure varies and reasoning paths are implicit rather than explicitly annotated

via “visual-reasoning-over-complex-scenes”

Open multimodal model for visual reasoning.

Unique: Trained on 77K complex reasoning samples (49% of instruction-tuning dataset) generated by GPT-4, explicitly optimizing for multi-step inference over visual content; this heavy weighting toward reasoning tasks differentiates it from captioning-focused vision models

vs others: Outperforms general-purpose vision models on reasoning-heavy benchmarks like Science QA (92.53% accuracy) because nearly half its training data is reasoning-focused, whereas models like CLIP or standard captioning systems optimize for classification or description
