Multimodal AI 101: What you need to know

Artificial intelligence (AI) is one of the most fascinating and controversial technologies of our time. It has the potential to redefine what it means to be human and upend every industry on the planet. 

In the past few years, AI’s impact has been felt across various sectors from retail to healthcare, transforming how businesses operate and interact with customers. These include chatbots for customer interaction, decision-making through data analytics for business decisions, and more. 

The rise of AI is having a profound impact on businesses and society as a whole. As we continue to see advances in AI technology, we can expect even greater changes in how we live and work.

How has Artificial Intelligence evolved?

Artificial intelligence has come a long way since its inception. In the early days, AI relied heavily on the rules-based systems humans created. It meant that AI was only as good as the rules programmed into it. 

Over time, AI has become increasingly more sophisticated and can now learn and improve itself without human intervention, thanks to Machine Learning (ML). It is a process of teaching computers to learn from the available data without being programmed. It makes AI much more effective at completing tasks and solving problems.

The current state of AI is still far from perfect, but it has come a long way from its humble beginnings. With continued development, AI will likely become even more powerful and widespread in the years to come.

Currently, AI applications can be deployed in several ways, including: 

And the latest trend in the field of Artificial Intelligence is Multimodal AI.

What is Multimodal AI?

Multimodal AI is a branch of artificial intelligence that deals with processing and interpreting multiple modalities of data. In other words, it is concerned with how machines can learn to understand the world around them using more than one type of information.

Multimodal AI has its roots in cognitive science, which studies how the human mind works. Cognitive science aims to understand how we process information and make decisions. Understanding how the human mind works can build AI systems that mimic or exceed human capabilities. 

One of the critical insights from cognitive science is that the human mind uses multiple modes of data to understand the world. For example, when you see a picture of a dog, you process not only the visual information but also any accompanying text (e.g., “dog,” “canine,” etc.). This allows you to understand the concept of a dog completely.

Multimodal AI takes this insight from cognitive science and applies it to artificial intelligence. 

While this might sound like a relatively simple concept, the implications of multimodal AI are far-reaching and can potentially revolutionise the way we interact with technology. 

What data sources does Multimodal AI use?

Multimodal AI uses a variety of data sources to train and operate its models. These data sources can include: 

  • Text 
  • Images 
  • Audio
  • Video 

However, there is no limit to the data types that can be used. As long as there is a way to represent the data in a machine-readable format, it can be used for multimodal AI.

The data used to train and operate Multimodal AI models can come from many different sources, including public databases, private companies, and individuals.

How does Multimodal AI work?

The goal of multimodal AI is to provide a more complete understanding of the data than any single modality could provide on its own. By using multiple data modes, multimodal AI systems build a more complete understanding of the world.

For example, when analysing an image, multimodal AI can consider the image’s context, metadata, and accompanying text to provide a complete understanding of what the image represents.

Multimodal AI has been shown to outperform traditional AI models in several tasks, such as image captioning and machine translation. This is because multimodal AI can use all the available information rather than just relying on a single modality, making it more robust and accurate.

What’s the difference between single-modal vs. multimodal AI?

When it comes to artificial intelligence (AI), there are two main types: single-modal and multimodal. Single-modal AI focuses on one specific modality, such as text, images, or audio. On the other hand, Multimodal AI takes into account multiple modalities simultaneously.

For example, a single-modal AI system that only uses text data would have difficulty understanding an image. However, a multimodal AI system that uses both text and image data would be able to understand the image and make a prediction based on the context of the text.

Multimodal AI is particularly powerful because it can take advantage of all the different data types available today. 

What are the challenges of multimodal AI?

One of the main challenges for multimodal AI is that it can be difficult to train models due to the need for large amounts of data from different modalities. 

For example, when trying to predict a person’s next movement, there might be dozens of different modalities that could be relevant, including visual (e.g., what they are looking at), auditory (e.g., what they are saying), and contextual (e.g., the time of day or location). 

Another challenge is that some modalities can be very noisy, making it difficult for AI systems to learn from them. For example, speech recognition is often error-prone, and body language can be difficult to interpret accurately. 

Finally, multimodal AI systems can be complex and computationally intensive, making them expensive to develop and deploy.

What are the benefits of multimodal AI?

Multimodal AI can offer many benefits, including the ability to:

  • Understand multiple modalities of data simultaneously
  • Enhance decision-making by providing a more comprehensive view of data
  • Reduce bias in decision-making by considering various perspectives
  • Improve communication by understanding the nuances of language and gestures
  • Increase efficiency by automating tasks that would otherwise be manual

What are the real-world applications of multimodal AI?

Multimodal AI systems are becoming increasingly commonplace as the technology matures and more businesses realise the benefits of using AI to automate tasks. Here are some practical applications of multimodal AI that are being used today:

Automated customer service: Multimodal AI can automatically respond to customer queries, regardless of their channel (email, chat, social media, etc.). This can free up customer service agents to focus on more complex issues and improve overall efficiency.

Intelligent virtual assistants: Virtual assistants powered by multimodal AI are becoming increasingly popular as they can understand and respond to questions in natural language, making them much more user-friendly than traditional voice-based assistants.

Robotic process automation: Multimodal AI can automate low-level tasks in various industries, from manufacturing to healthcare, improving efficiency and accuracy while freeing employees for more value-added work.

Predictive maintenance: Multimodal AI can monitor industrial equipment for signs of failure and predict when maintenance will be required. This can help businesses avoid downtime and improve safety by addressing problems before they cause significant issues.

Security and surveillance: Multimodal AI systems can be used for security applications such as facial recognition and object detection.

Multimodal AI is still in its early stages of development, but it has the potential to revolutionise how we interact with technology.
