Artificial intelligence has witnessed rapid advancements in recent years, with a notable shift towards multimodal AI. This technology integrates various types of data inputs, such as text, images, and speech, to provide more comprehensive and nuanced insights. The multimodal AI market is expected to surge over the next several years with a CAGR of around 30% from 2024 to 2032.
Multimodal AI is already being utilized in various industries, such as healthcare, automotive, and finance. Further, with the rising complexity of real-world problems, it has created the need for improved understanding of AI systems which is why multimodal AI is popular in today’s technology industry.
What is Multimodal AI?
Multimodal AI is a subfield of artificial intelligence characterized by combining data from multiple sources or modalities, such as text, images, audio, or video, to better understand the data. In contrast to traditional AI models that work with a single modality, multimodal AI takes a step forward by merging different diversity in understanding, context, and performance.
The primary idea of multimodal AI is to use various types of data to make a more detailed and broader analysis. For example, a multimodal AI system can lock in a video and interpret it not only from visual content but also from sound and text related to the video in question.
Example: Think about a customer service AI system with text and face. Suppose a customer interacts with a chatbot, and the system has access to video of the customer’s face. In that case, it can analyze the text of the customer’s messages and facial expressions to gauge their emotional state. For example, if a customer says a text such as “I’m frustrated with the service,” informing them that they are upset with the service. The customer demonstrates a sign of annoyance in the facial expressions. The urgency and emotion of the AI can thus be understood better and enhanced, making the AI’s response more convincing.
