Even in its early stages, multimodal AI has surpassed human performance in many tests. This is significant because AI is already ingrained in our daily lives, and such advancements have implications for various industries and sectors. Multimodal AI seeks to replicate the functioning of the human brain by utilizing an encoder, input/output mixer, and decoder. This approach empowers machine learning systems to handle tasks involving images, text, or both. By connecting different sensory inputs with related concepts, these models enable more comprehensive and nuanced problem-solving. Developing multimodal AI involves aligning the internal representation of the model across all modalities, a crucial step. By incorporating diverse forms of sensory input such as text, images, audio, and video, multimodal systems can tackle complex problems that were previously challenging. As this technology gains momentum, numerous organizations are adopting it to enhance their operations. Moreover, the development cost of multimodal models is not prohibitively expensive, making it accessible to a wide range of businesses. This article will delve deeper into the concept of multimodal models and explore how they function.

2. Explain how does Multimodel Models work?

Multimodal AI fuses various data types like text, images, audio, and video, employing unique unimodal neural networks for each input form. The networks, such as convolutional neural networks for images and recurrent neural networks for text, extract key features from their respective data using three central components. Unimodal encoders constitute the first component, processing each data modality independently. An image encoder handles images, while a text encoder manages text. After this, the fusion network integrates the features that the unimodal encoders extract from diverse modalities into a single, unified representation. Several fusion techniques, like concatenation, attention mechanisms, and cross-modal interactions, facilitate this integration. The final component is the classifier, which makes predictions based on the fused data. Task-specific, this component makes the ultimate decision or classification. The modularity of multimodal architectures, their ability to combine different modalities, and adaptability to new tasks and inputs make them advantageous over unimodal AI systems, delivering more dynamic predictions and superior performance.

3. Exploring Real-life Applications of Multimodal AI

1. Image description and text-to-image generation

OpenAI's programs, CLIP, DALL-E, and GLIDE, can describe images and generate images from text. CLIP uses separate image and text encoders to predict the association between images and their descriptions in a dataset. DALL-E, a large variant of GPT-3, generates images that align with input text, which CLIP then ranks. GLIDE, DALL-E's successor, uses a diffusion model for image generation, leading to even more realistic and creative images.

2. Visual question answering

In visual question answering, models like Microsoft's METER and the Unified Vision-Language Pretrained Model (VLMo) showcase the potential of multimodal AI. They combine vision and language to answer complex questions, indicating the limitless possibilities for such models.

3. Text-to-image and image-to-text search

In web search, multimodal learning plays a crucial role, as exemplified by the WebQA dataset from Microsoft and Carnegie Mellon University. Models identify image and text-based sources to answer a query, reasoning through these sources to generate a response. Google's ALIGN model also tackles multimodal search, combining visual and text encoders using contrastive learning.

4. Video-language modeling

Despite historical challenges with video-based tasks, advancements in video-related multimodal tasks are progressing. Microsoft's Project Florence-VL and its introduction of ClipBERT, VIOLET, and SwinBERT exemplify this progress. These models use transformer-based architectures, combined with parallel learning modules, to extract data from different modalities and unify them into a single multimodal representation.
