Exploring Multimodal AI
Once again, here we go! The "next big thing" in artificial intelligence technology is multimodal AI. But what does multimodal actually mean and how is it different from the AI models that are so familiar to us?
How do you define modality?
Modality in artificial intelligence refers to a variety ?of data types. Text, photos, audio, and video are just a few examples of data modalities.
Multimodal AI: What is it?
Artificial intelligence (AI) systems that can synthesize multiple data inputs to generate more complicated yet accurate results than unimodal systems are generally referred as multimodal AI systems.
OpenAi's GPT-4V is an example of a multimodal AI system . What is the key difference between GPT-4 and current V version? In addition to text, images can also be processed by vision. Runway Gen-2 for creating videos and Inworld AI for creating characters for games and virtual environments are two more examples.
As we'll see below, multimodal AI mainly focuses on its potential, which is vast. However, be aware that multimodal AI is still very much in its early stages.
Multimodal vs. unimodal AI
Many generative AI systems are limited to processing a single data modality, such as text, and producing output in that modality only. It is therefore unimodal.
Users can supply many input modalities and generate outputs using those modalities thanks to multimodal AI. A multimodal system, for instance, may generate both text and images if you feed it both.
How multimodal AI works
Multimodal AI systems are trained to identify patterns between different types of data inputs. These systems have three primary elements:
Remember how we discussed modality? A multimodal AI system actually consists of many unimodal neural networks. These make up the input module, which receives multiple data types.
The data from each modality is then combined, aligned, and processed by the fusion module. A variety of methods are used in fusion, including early fusion (concatenating raw data). The output module presents the results at the end. These vary greatly depending on the original input.
Benefits of multimodal AI
One of the major upsides of multimodal AI models is context.?Because these systems can recognize patterns and connections between different types of data inputs, the output is more accurate, natural, intuitive, and informative. And, of course, it’s more human.?
Multimodal AI can also solve a wider variety of problems than unimodal systems.

Challenges & drawbacks of multimodal AI
As with any new technology, multimodal AI comes with several downsides, including…
Higher data requirements
Multimodal AIs would require large amounts of diverse data for it to be trained effectively. Collecting and labeling these data is expensive and time-consuming.
Data fusion
Multiple modalities display various kinds and intensities of noise at various times, and they aren't necessarily temporally aligned. The diverse nature of multimodal data makes the effective fusion of many modalities difficult, too.
Alignment
It’s challenging to properly align relevant data representing the same time and space when diverse data types (modalities) are involved.?
Translation
Translation of content across many modalities, either between distinct modalities or from one language to another, is a complex undertaking known as multimodal translation. An example of this translation is asking an AI system to create an image based on a text description.?
One of the biggest challenges of multimodal translation is making sure the model can comprehend the semantic information and connections between text, audio, and images. It's also difficult to create representations that effectively capture such multimodal data.?
Representation
Managing various noise levels, missing data, and merging data from many modalities are some of the difficulties that come with multimodal representation.
To sum up, the development of multimodal AI systems indicates that artificial intelligence has a bright future. Through the use of multiple data streams, these systems provide a way forward for improved comprehension, stronger functionality, and smooth communication between humans and computers. Although there are still issues with data fusion and?algorithm design,?multimodal AI has the potential to completely transform a number of industries, including robotics, entertainment, and healthcare as well as education.
The line that separates ?human and machine intelligence may become blurry as research and development proceed, kicking off in a new era of AI co-creation and collaboration. It remains to be seen if we will experience actual consciousness or just sophisticated pattern recognition.
