Are you fully aware that AI has made leaps in transforming the world around us with the help of two distinct approaches: Multimodal AI and Unimodal AI? But about this, if you have no proper idea, then you should not forget to have a look at this information.

It’s crucial to understand these two paradigms and their differences because we are in an era where machines can not only “think” but also “see,” “hear,“ and “understand“ like never before. So, to make you more familiar with everything, let’s dive into this informational post and start by first knowing about the modals.

What is Unimodal AI?

This modal refers to those systems that process and analyze the information in such a way that only a single source is required. With this, the AI even specializes in working with one type of input at a time.

Apart from this, AI in unimodal systems is designed in such a way that you can understand, interpret, and make decisions based on a single type of sensory input.

For example, GPT-3, or ChatGPT, is an unimodal AI that specializes in text data. The models can produce coherent sentences, answer questions, and even have conversations, all dependent on the language data used to train them.
In fact, even image recognition models such as CNNs are commonly trained purely to classify images on the basis of pixel data conversion.
For example, speech recognition systems—Siri and Google Assistant—use purely audio signals; they interpret audio language for a reply.

How Does Unimodal AI Work?

Unimodal AI relies on a single input-output pipeline. For example:

A vast volume of text-based data—be that a book, article, or even a website—would feed a training model for any kind of text-based AI.
It can be trained on image datasets to identify objects and classify images. Indeed, they can even generate new visuals.
Audio-based AI models: In these systems, only training data, in the form of sound waves and only audio pattern recognition, are used in applications such as speech-to-text or speech-to-speech.
Unimodal AI is very specialized since it only has one modality. A model designed to generate text, for example, would be excellent at generating text but would not have the capacity to process or understand images or sounds unless it was completely redesigned or supplemented with other components.

What is Multimodal AI?

However, with multimodal AI, what is referred to is simultaneously integrating and processing artificial intelligence of multiple kinds of data or even modalities. This means a mixture of text, images, audio, and perhaps even video into one system. That is the kind of benefit multimodal systems afford because they actually let AI have a far better sense of the world by jumping on multiple senses or forms of data. As a human, a multimodal system computer does not depend just on seeing and hearing but depends on all forms of sensory input, to be more specific.

One of them is GPT-4, which, in one way or another, can both process images and text and use this to describe a scene, answer questions related to an image, or even generate visual content given a description in the text. More complex multimodal systems are:

Video analysis systems that could understand both the visual or image data and the auditory or sound data and hence look out for action or dialogues.
Those robots that can see and touch perceive their surroundings, which integrate information from cameras, pressure sensors, and microphones to behave more intelligently with the world.
Healthcare AI: It can see medical images, such as MRIs or X-rays, with patient records to make a better diagnosis or even recommend treatment.

What Does Multimodal AI do?

Multimodal AI systems exploit customized architectures that are capable of mashing diverse forms of data streams into one model. Here is just one general example:

Data fusion. All forms of data collected and aligned are to be operated on together. For example, when analyzing a video, the system may collect visual frames along with sound or dialogue data that it can associate with them.
Cross-modality learning: It learns relationships between different modalities. This means that it learns associations between sound and/or visual objects, like associating barking sounds with pictures of dogs.
Integrated decision-making: With multiple AIs, decisions are considered based on information acquired from any avenue. Hence, the system is quite robust and strong and takes very complex decisions about differing senses.

After knowing about these two to have a better idea, let’s dive in and learn about the major differences between multimodal AI vs. unimodal AI. Let’s dive in:

Data types used

Unimodal AI. Learn from just one type of modality, such as text, images, or speech.
Multimodal AI: Combine and execute functionalities that make use of multimodal interaction: text, images, speech, and video.

Flexibility

In unimodal AI, one kind of data is applied to a specific application.
Multimodal AI: Much more versatile in handling tasks involving the integration of multiple data types for a more holistic understanding.

Complexity

Unimodal AI: simpler structure, and thus less overhead computation.
Multimodal AI: More advanced; they use complex algorithms for fusing, aligning, and interacting amid modalities.

Job specialization

Narrow, task-specific jobs like image classification and speech recognition are specializations for one thing.
Multimodal AI does harder, more complex jobs, such as multimodal search or autonomous driving.

Data Integration

One Single Stream: It allows feeds from a single stream of data that does not embody or synchronize another type of data.
Multimodal AI: Needs methods that combine data of high complexity to merge and interpret together.

Applied Works

Unimodal AI: Applied wherever specialized expertise is needed, such as text generation, object recognition, or speech-to-text applications.
It finds utility in scenes demanding multi-input, such as robotics, health diagnostics, and self-driving cars.

In Summary
