Discover how Multimodal AI is revolutionizing the way we interact with technology by integrating multiple forms of data to create more intuitive and efficient systems. Multimodal AI integrates various data types such as image, text, and speech and combines them to achieve better results using multiple intelligent algorithms.

Understanding the Basics of Multimodal AI

Multimodal AI encompasses artificial intelligence systems that can simultaneously process and comprehend multiple data types. In contrast to traditional AI, which might concentrate on a single input form like text, images, or audio, multimodal AI combines these diverse data types to offer a more holistic understanding of information. This ability enables more refined and precise interpretations, making it particularly valuable in intricate scenarios where single-mode data might be insufficient.

By utilizing various data modalities, these AI systems can produce outputs that are richer and more contextually informed. For instance, a multimodal AI could assess a video by integrating visual data (the images), audio data (the sounds), and textual data (subtitles or spoken words) to create a more comprehensive and accurate depiction of the scene.

Multimodal AI is an advanced form of artificial intelligence that simultaneously integrates and processes different data types, including text, images, audio, and video. This capability enables it to generate insights, make predictions, and create content in a manner that simulates human perception and understanding. Here's what you need to know about multimodal AI:

Definition of Multimodal AI

Multimodal AI refers to systems that can analyze and interpret various modalities of data at the same time. Unlike traditional single-modal AI, which focuses on one type of data (e.g., only text or only images), multimodal AI combines different data types to achieve a more nuanced understanding of information. This integration enables the system to perform complex tasks that require context from multiple sources

How Multimodal AI Works

Multimodal AI is an advanced form of artificial intelligence that integrates and processes multiple types of data—such as text, images, audio, and video—to generate more comprehensive insights and responses. Here’s how multimodal AI works, based on the key components and processes involved:

7. Storage and Compute Infrastructure

Robust storage solutions and computational resources are essential for managing the large volumes of data generated by multimodal AI systems. High-performance computing (HPC) environments support the intensive processing requirements of these applications.

The technologies associated with multimodal AI enable it to create a richer understanding of the world by integrating diverse data types. By leveraging input modules, fusion techniques, NLP, computer vision, audio processing, and effective integration systems, multimodal AI can perform complex tasks that single-modal systems cannot achieve. This capability opens up numerous applications across industries, enhancing human-computer interaction and enabling more intuitive user experiences.

Multimodal stack technologies

Retrieval-augmented generation (RAG) is the foundation of the multimodal AI technology stack. There are a number of different components that come together to provide Input, Fusion, and Output results. With RAG, these components seamlessly interact with each other to provide the complete AI experience.

Natural language processing

Probably the most important advancement in AI has been natural language processing (NLP). With NLP, multimodal AI interacts with data and humans naturally and uses these interactions in conjunction with diverse data types like images, video, sensor data, and much much more. NLP creates a human-computer interaction that wasn’t possible in the past.

Computer vision

NLP opens the AI world to language. Computer vision technologies open the AI world to visual data. With computer vision, AI interprets, understands, and processes visual information like images and videos—summarizing, captioning, or interpreting the visual data in real time. From this, AI creates real-time transcripts or captions for the deaf, or audio interpretation for the blind.

Text analysis

Text analysis works with NLP to understand, process, and generate documents for use in Multimodal AI systems. This is seen in NLP chatbots that use product documentation, emails, or other text-based inputs as training data, generating text-based responses or outputs.

Integration systems

Something required for successful multimodal AI systems is the ability to integrate with external data sources. Leveraging a RAG-based architecture prioritizes this integration and makes integration a core part of the technology stack used by multimodal AI systems.

RAG provides the foundation for bringing in multiple data inputs. RAG distributes the outputs to applications in application-specific structures. This allows legacy-based systems and newly developed applications to integrate seamlessly into the AI process.

Storage and compute

This is probably the broadest-scoped technology in the multimodal AI technology stack. Storage and computing have a critical impact on the development, deployment, and operation of the AI system. When it comes to storage, a multimodal AI system needs the ability to provide data storage, data management, and version control for all of the unique datasets used by the AI system. In addition, it needs significant computation power that can be used for training, real-time data processing, and data optimization.

Traditional environments have brought storage and computing together, but in modern multimodal AI systems, segmentation and virtualization of storage and compute operations provide significant benefits.

What is the difference between multimodal and generative AI?

Terminology in the AI realm can be quite complex, often posing significant challenges due to the vast array of models and technologies involved. Within this expansive field, there are multiple AI models to consider, each with its unique capabilities and applications. Among these, two powerful and distinct types are Generative AI and Multimodal AI.

Generative AI models have surged in popularity recently, largely due to their ability to create new content. These models are trained using existing data, which they analyze to understand patterns and structures. Once trained, Generative AI can produce content that closely resembles the original data it was trained on, whether it's generating realistic images, composing music, or writing text. This capability makes Generative AI particularly valuable in creative industries and applications where the generation of novel and diverse content is essential.

On the other hand, Multimodal AI takes a different approach by focusing on the simultaneous processing and integration of multiple types of data. Instead of being confined to a single data type, like text or images, Multimodal AI systems handle a variety of data inputs at once—such as combining textual, visual, and auditory information. This comprehensive processing capability allows Multimodal AI to achieve a more holistic understanding of complex scenarios, enhancing its ability to interpret and respond to information accurately.

The primary distinction between these two AI models lies in their core functions: while Multimodal AI emphasizes the processing and comprehension of diverse data inputs to form a cohesive understanding, Generative AI excels in identifying patterns within data and leveraging those patterns to generate new, similar content. These complementary capabilities mean that Generative AI can be integrated as one of many output modules within a Multimodal AI framework, providing enriched outputs based on the integrated, multimodal data it processes. This integration highlights the synergistic potential of combining different AI models to create more robust and versatile AI systems.

The Technology Behind Multimodal AI

The core technology that powers multimodal AI involves advanced machine learning algorithms and neural networks capable of processing and integrating different types of data. One key component is the use of Convolutional Neural Networks (CNNs) for image and video data, and Recurrent Neural Networks (RNNs) or Transformers for text and audio data. These models are trained on large datasets that include multiple data types, enabling them to learn the correlations and relationships between different modalities.

Furthermore, attention mechanisms play a crucial role in multimodal AI. They help the model focus on the most relevant parts of the input data, improving the system's efficiency and accuracy. Natural Language Processing (NLP) techniques are also integral, allowing the AI to understand and generate human language in combination with other data forms.

Applications and Real-world Examples

Multimodal AI has a wide range of applications across various industries. In healthcare, it can assist in medical diagnostics by analyzing a combination of medical images, patient records, and genetic data to provide more accurate diagnoses. In the automotive industry, multimodal AI powers advanced driver-assistance systems (ADAS) by integrating data from cameras, radar, and LiDAR sensors to enhance vehicle safety and autonomy.

Another compelling application is in the field of virtual assistants and customer service chatbots. These systems can understand and respond to user queries more effectively by integrating voice recognition, text analysis, and even facial recognition. Real-world examples include Google's Multimodal Transformer model and OpenAI's GPT-3, which can understand and generate text based on various input modalities.

Healthcare

Back in 2020 when Covid 19 was at its peak, we saw a rapid growth of telemedicine. People could meet virtually with physicians to provide safe and expedited personal healthcare. Today, with multimodal AI virtual offices, visits include pictures, text, audio, and video that’s analyzed by an AI physician's assistant. Symptoms from all the different inputs are evaluated and a rapid diagnosis is provided for things like burns, lacerations, rashes, allergic reactions, etc.

We’ve also seen the rise of electronic medical records (EMR) that replace paper folders (with alphabetized last name labels). From there, electronic health records (EHR) efficiently share digital patient records (EMRs) across practices. This digital visibility positively impacts patient care—doctors spend more time treating patients and less time tracking down and managing patient information.

Retail

In retail, multimodal AI provides personalized experiences based on images, video, and text. How many of us have ordered clothing from an online retailer only to realize that it doesn’t look as good as it did in the picture? With multimodal AI, consumers can now upload images/videos of themselves and generate 360 degree views of garments on their bodies. This advancement shows how it fits, looks, and flows in a natural way prior to making the purchase.

Entertainment

Like retail, multimodal AI has the potential to revolutionize the entertainment industry. Content consumers provide multiple input types from personalized content suggestions to real-time gaming content based on gamers’ experiences. Gaming may offer incentives when a player is losing, for example.

With multimodal AI, these games leverage video input of player sentiment to create offers before the players get frustrated and quit playing. Or they tailor the gaming experience based on that sentiment, presenting custom, real-time content that players enjoy.

Multimodal AI and language processing

The possibilities for multimodal AI and language processing are limitless.

Incorporating facial expressions, tone of voice, and other stimuli changes the way we interact with technology.

  • Customer service assistants listen to customer support calls and provide real-time analysis of customer frustration levels.
  • Manufacturing processes incorporate multimodal AI for tolerance and waste management by incorporating text, video, and imagery.

Multimodal AI changes what technology can do in our lives.

How to use multimodal AI for your business

Addressing challenges might seem overwhelming, but leveraging multimodal AI in business is very achievable with process forethought and by following simple guidelines.

  • Identify business goals and use cases: This is the first step in the process. Clearly define why your business should leverage multimodal AI and have a clearly-defined use case that is tangible.
  • Data collection and integration: Next, the right approach to data collection and integration is key. One primary question that needs to be asked is “Can and should the data we use be shared across multiple AI applications?” Leveraging an architecture like retrieval-augmented generation (RAG) may be worth the initial investment.
  • Data processing: Once you have an approach and you’ve defined inputs, look at how you’ll process data—ultimately defining the fusion model/approach you will use.
  • Model selection and development: The other question is whether a general purpose large language model (LLM) is needed? Would a small language model that has been fine-tuned to a specific domain be more appropriate? Most applications should not develop a model from scratch, but leveraging a small language model for domain-specific knowledge can provide value.
  • Scalability and performance monitoring: Leveraging multimodal AI within the business takes into account scalability and performance. With massive amounts of data being used to train and prompt multimodal AI systems, monitoring system scalability and performance is required to meet users’ demands, manage costs, and provide predictable response times.
  • Integration into business processes: Once the technology decisions have been made, the next layer looks at how responses will integrate into the business process. This is where starting with a RAG approach provides significant benefit, because business processes can be natively-integrated into the workflow.
  • Testing and validation: One of the interesting challenges of multimodal AI is the impact inaccurate results have on perception. A human answering random questions with 80% accuracy would be considered pretty good. But a machine with 80% accuracy is considered intolerable. Because of this, testing and Human-in-the-Middle validation is key.
  • Privacy and ethical considerations: Another concern that has to be weighed is data sensitivity and the ethical considerations of using specific data. Is the data fed into the AI workflow managed, curated, and protected appropriately to protect the users and consumers of that data? This is where organizations need strong data governance when using data for training AI systems.
  • User training and adoption: AI systems in place, proper user training is key to successful adoption. The potential of multimodal AI to change the way an individual works and communicates is massive, but that potential comes with a significant change in how users perform their day to day operations. Being able to showcase productivity improvements by training users how to leverage these new technologies is key to wide-scale adoption.
  • Feedback and continuous improvement: Recursive feedback from users and the AI systems is fundamental to providing continuous improvement and more accurate responses. Things like human sentiment, Human-in-the-Middle validation, and response feedback loops, give good AI interactions a vehicle to become great—by integrating real-time feedback on responses and interactions.
  • ROI analysis: Lastly to provide real value to the business, there has to be a return on the investment made in multimodal AI. Whether you are in retail, healthcare, logistics, or manufacturing, understanding the business value—and providing metrics on what the business gains by implementing multimodal AI—is fundamental for adoption and growth. AI isn’t right for every problem. Understanding where AI provides value to the business creates space for projects that use AI to be fine-tuned to the use cases that matter.
