Exploring the next frontier of AI: Multimodal systems and real-time interactionAI

In the realm of artificial intelligence (AI), the integration of senses - seeing, hearing and interacting - represents a frontier that is rapidly expanding thanks to the proliferation of large multimodal models (LMMs).

The expanding capability of AI systems to process and understand multimodal data offers groundbreaking possibilities for applications in Internet of Things (IoT), mobile, robotics and more. It also opens the door to fundamental changes in how we engage with technology, allowing for the kind of nuance and real-time flow you would see with human interactions.

One of the significant advancements in this field is the ability to run AI systems directly on devices. This development not only reduces memory costs and latency, but also enhances reliability and security. Qualcomm AI Research has been at the forefront, pushing the boundaries with innovations like the world's first multimodal large language model (LLM) running on an Android phone earlier this year. This breakthrough demonstrates the potential for more sophisticated AI applications that are accessible on everyday devices:

Real time solution

Real time model streaming, which is the ability to collect and ingest data from various sources and process it in real time, is a key requirement for an AI model to understand its environment and interact with nearby humans.

An auto-regressive language model is a useful component of such a multimodal agent because it's already able to perform a dialogue with a user. Additionally, language makes it easy to encode surrogate tasks for a degree of "common sense" to emerge.

As a result, a streaming multimodal LLM is seen as a solution to two challenges facing open-ended, asynchronous interactions with situated agents:

  • Limited to turn-based interactions about offline documents or images.
  • Limited to capturing momentary snapshots of reality in a visual question answering (VQA) type of dialogue.

A few years ago, we expanded generative AI efforts to study multimodal language models, with the main motivation to extend the use of language from mere communication to reasoning and enhancing a model's common sense understanding of everyday situations.

We have made progress with end-to-end training of situated vision language models, where the model can process a live video stream in real time and dynamically interact with users. While this technology may provide immediate value in the form of coaching and live assistance, we believe that even the long-term path towards the current widely extolled humanoid robots will require enabling AI models to reason and interact with us using common sense.

Towards an integrated interactive solution

Qualcomm Technologies, Inc. continues to support the machine learning community by providing tools that enable the development of applications based on multimodal interactions. These tools foster innovation and allow developers to explore new frontiers in AI applications, from AI models with enhanced common-sense reasoning to intelligent personal assistants.

In the past years, the Qualcomm Innovation Center (QuIC) has open-sourced these tools on Github.

Our research, "Is end-to-end learning enough for fitness activity recognition?", has shown that efficient visual streaming at inference time can be enabled using 3D steppable, causal convolutions. Now developers can enhance their applications with the ability to see and interact with humans using any RGB camera thanks to the Sense inference engine.

End-to-end training in conjunction with the distillation of multimodal reasoning capabilities (Look, remember and reason: Grounded reasoning in videos with language models) allows a model to provide useful and accurate feedback in real-time. We have incorporated this seamless approach in the fitness demo that we showcase in the "Integrating senses in AI" webinar.

Multimodal learning will continue to advance

The future of AI lies in its ability to function in real-time and with a situational awareness of its surroundings, enabling machines to interact with the world in ways that are as complex and nuanced as human interaction. Qualcomm Technologies is at the forefront of this technology, pushing the boundaries of what AI can achieve with multimodal learning and on-device processing. As AI continues to evolve, it can transform our interactions with technology, making them more intuitive, efficient and secure.
