Towards Comprehensive Evaluation of Multimodal Language Models: Introducing OmniBench

Q: How can the OmniBench benchmark be extended to include additional modalities beyond image, audio, and text, such as video, sensor data, or even haptic feedback, to further push the boundaries of multimodal understanding?

To extend the OmniBench benchmark beyond the current modalities of image, audio, and text, several strategies can be employed. First, incorporating video as a modality would require the development of tasks that assess temporal reasoning and motion understanding, as video data inherently contains dynamic information. This could involve creating scenarios where models must interpret actions over time, linking visual frames with corresponding audio cues and textual descriptions. Additionally, integrating sensor data, such as temperature, pressure, or motion sensors, could enhance the contextual understanding of environments. Tasks could be designed to require models to interpret sensor readings alongside visual and auditory inputs, fostering a more holistic understanding of real-world scenarios. For instance, a model could be tasked with identifying the cause of a temperature spike in a video of a kitchen, using both visual cues and sensor data. Incorporating haptic feedback as a modality presents unique challenges, as it involves tactile sensations that are not easily represented in traditional data formats. However, creating simulated environments where models can "feel" interactions through haptic data could be explored. This would necessitate the development of new annotation protocols that capture the nuances of tactile experiences and their relationships with visual and auditory inputs. Overall, extending OmniBench to include these additional modalities would require innovative task designs, robust data collection methods, and comprehensive annotation strategies to ensure that models can effectively learn and reason across a broader spectrum of sensory inputs.

Q: What novel training strategies or architectural innovations could help address the performance limitations of existing open-source omni-language models observed in the OmniBench evaluation?

To address the performance limitations of existing open-source omni-language models (OLMs) as observed in the OmniBench evaluation, several novel training strategies and architectural innovations can be considered. One promising approach is the implementation of multi-task learning frameworks that allow models to simultaneously learn from various modalities. By training on tasks that require the integration of visual, auditory, and textual information, models can develop a more nuanced understanding of how these modalities interact. This could involve using shared representations that capture common features across modalities, thereby enhancing the model's ability to generalize across different contexts. Another strategy is to leverage transfer learning from pre-trained models that excel in specific modalities. For instance, models that have been fine-tuned on large datasets for image recognition or speech understanding could be adapted to the omni-language context. This could involve using techniques such as knowledge distillation, where a smaller model learns from a larger, more capable model, thereby inheriting its strengths while maintaining efficiency. Architectural innovations, such as attention mechanisms that dynamically weigh the importance of different modalities based on the context, could also enhance performance. By allowing models to focus on the most relevant information from each modality during inference, these mechanisms can improve reasoning capabilities and reduce noise from less relevant inputs. Finally, incorporating feedback loops where models can iteratively refine their understanding based on previous outputs could lead to improved accuracy. This could be achieved through reinforcement learning techniques, where models receive rewards for correctly integrating information from multiple modalities, thus encouraging better performance over time.

OmniBench is a novel benchmark designed to rigorously evaluate multimodal large language models' ability to recognize, interpret, and reason across visual, acoustic, and textual inputs simultaneously.

Tiivistelmä

The paper introduces OmniBench, a pioneering universal multimodal benchmark, to evaluate the capability of multimodal large language models (MLLMs) in processing and reasoning across visual, acoustic, and textual inputs simultaneously.

The key highlights of the paper are:

OmniBench is distinguished by high-quality human annotations, ensuring that accurate responses require integrated understanding and reasoning across all three modalities.
The benchmark covers a comprehensive taxonomy of tasks, progressing from fundamental perception to complex inference, enabling a holistic assessment of MLLMs' capabilities.
Initial findings reveal critical limitations in the omni-understanding capabilities of existing open-source MLLMs, which barely exceed random guessing accuracy or struggle to follow instructions when provided with image and audio together.
In the setting of using text as alternatives for audios and images, the open-source vision-language models and audio-language models show relatively better results but remain at a preliminary level of capability to understand the given tri-modal context.
Compared to the open-source MLLMs, the proprietary model demonstrates superior overall performance and balanced accuracy across audio types, but its accuracy remains below 50%, underscoring the challenging nature of OmniBench.

The paper advocates for future research to focus on developing more robust tri-modal integration techniques and training strategies to enhance omni-language model performance across diverse modalities.

Lainaukset

"Recent advancements in multimodal large language models (MLLMs) have aimed to integrate and interpret data across diverse modalities. However, the capacity of these models to concurrently process and reason about multiple modalities remains inadequately explored, partly due to the lack of comprehensive modality-wise benchmarks."
"We distinguishes OmniBench by enforcing a unique constraint: accurate responses necessitate an integrated understanding and reasoning of all multimodal contexts. This approach ensures a more realistic and challenging assessment of multimodal large language models, mirroring the complex, interconnected nature of human cognition."
