What is Multimodal Artificial Intelligence ?
Developments and breakthroughs in generative Artificial Intelligence are making ever greater strides toward its ability to perform a wide range of cognitive tasks (AGI). Despite this, it still cannot think like a human. The human brain relies on 5 senses, which serve as collectors of information from the surrounding environment. After that, the information is processed and stored in our brains.
Generative models such as ChatGPT can only accept and generate one type of data. That is, they are unimodal. They were mostly used to provide text prompts and generate a text response.
Multimodal learning aims to increase the ability of machines to learn by presenting them with sensory types of data, i.e. images, videos or audio recordings. With this model, the correlation between textual descriptions and associated images, audio or video is studied. Currently, multimodal learning opens many perspectives for the modern technological world. Their ability to generate multiple types of outputs allows us to see new opportunities and developments.
Difference between Multimodal Artificial Intelligence and Unimodal
How Does Multimodal Artificial Intelligence Work?
Key Components of Multimodal AI Models
The development of transforms opened new possibilities for multimodal AI. The structure of transformers made it easier to experiment with the models’ architecture. Transformer consists of two parts – an encoder (transforms the input into a feature vector – a meaningful representation of the input information) and a decoder (generates information based on the encoder’s output). At first, transformers were used in language processing and text generation (LLMs) and later on were trained for image captioning, visual question answering, visual instruction, and other multimodal tasks. This leads to the possibility of creating a Large Vision-Language Models that have visual and textual encoders, can combine the representation of these two modalities, and can generate language responses (such as GPT-4V or LLaVA).
Another common approach is a combination of the Large Language Model with other capable models where LLM handles reasoning processes and other models (such as Latent Diffusion Models or TextToSpeech Models) generate new modalities. Such ansamble of models is more suitable to handle differences in architectures (transformers are great in handling language processing but diffusers are better for image generation) and allow higher modularity.
How Do Various Input Types Affect the Operation of Multimodal Models?
The multimodal AI architecture functions as follows for various input kinds. To facilitate comprehension, we have incorporated actual instances as well.
Text-to-image Generation and Image Description Generation
Some of the most revolutionary models of text-to-image generation and image description generation are GLIDE, CLIP, and DALL-E. Their specialty is the ability to create images from text and help describe images.
OpenAI CLIP has specific text and image encoders. They predict specific images in a dataset by training on massive datasets. In addition, if the model is subject to both an image and a corresponding textual description, it can use multimodal neurons. All this together represents a merged multimodal system.
DALL-E has about 13 billion parameters. It generates an image according to the input request. CLIP is used to rank images. This allows for accurate and detailed images.
CLIP also ranks images for GLIDE. However, it uses a diffusion model, which allows it to obtain accurate and realistic results.
Visual Question Answering
This query assumes correct answers to the questions based on the presented image. Microsoft Research is at the forefront of this, offering creative and innovative approaches to visual responses.
METER for example uses sub-architectures for rendering encoders, decoding modules, text encoders, and multimodal fusion modules.
The Unified Vision-Language Pretrained Model (VLMo) suggests the use of different encoders. Among them are dual encoders, fusion encoders, and a network of modular transformers. The flexibility of the model is primarily due to its levels of self-control and blocks with experts in specific modalities.
Image-to-text Search And Text-to-Image
Web search is also not aloof from the multimodal revolution. Datasets such as WebQA, which was created by researchers and developers at Carnegie Mellon University and Microsoft, allow models to identify sources of text and images with exceptional accuracy. This helps to answer the request correctly. However, the model will still need multiple sources to provide accurate predictions.
Google ALIGN (Large-scale Image and Noisy-Text Embedding model) uses alt text data from images on the Internet to train text (BERT-Large) and clear visual coders (EfficientNet-L2).
After that, the results of the encoders are combined using a multimodal architecture. This creates powerful models with multimodal representation. They can provide web searches in several modalities. At the same time, no additional configuration is required.
Video-Language Modeling
To bring Artificial Intelligence closer to natural, multimodal models designed for video were created.
Microsoft’s Florence-VL project uses a combination of transformer models and convolutional neural networks (CNN) in its ClipBERT project. They work with a thin selection on cards.
SwinBERT and VIOLET, iterations of ClipBERT, use Sparse Attention and Visual-token Modeling to perform better in answering video questions/subtitles/searches.
ClipBERT, SwinBERT, and VIOLET work similarly to them. Their ability to acquire video data from multiple modalities relies on a transformer architecture along with parallel learning modules. That is why they can integrate responses into a single multimodal representation.
Multimodal AI Models
Currently, many models contribute to the study of multimodality in Artificial Intelligence. Here are a few of them:
Mistral
Mistral is a large LLM language model. It has an open-source code and can efficiently and quickly process very long text sequences. Mistral’s architecture allows you to have a smaller number of parameters and get conclusions faster. This makes it convenient for applications that require large text sequences.
Efficient processing and generation of text in different languages is enabled by the architecture of the model, which is based on a mixture of experts (MoE), natural language processing (NLP) and natural language understanding (NLU).
LLaVA
LLaVA combines Large Language and Vision Assistant. It is a multimodal model that aims to improve the integration of visual and textual data. To provide visual language understanding, LLaVA leverages a visual encoder with a large Vicuna language model.
LLaVA can create content in various forms such as text, images, and audio. Thanks to this, it can provide the most accurate results in various tasks such as Science QA.
ImageBind
ImageBind was created by Meta as an advanced model of artificial intelligence. Its revolutionary nature lies in the perception and combination of data from different modalities. This creates a unified representation space. In it, the data of various modalities are transformed into a format understandable for the model. The model has the power to process data from six different modalities, such as images, text, audio, depth images, thermal images, and inertial measurement units (IMUs). ImageBind can better analyze and interpret complex datasets.
Gen 2
Gen-2, created by Runway Research, builds on the basic functions of its predecessor, Gen 1. To study large video data sets and create high-quality video outputs, it uses stable diffusion techniques. Gen-2 synthesizes video from text or images, creating realistic and coherent video.
CLIP
OpenAI has developed a CLIP (Contrastive Language-Image Pre-training) model for understanding image classification using natural language descriptions. The model does not require large datasets with labels and thus departs from traditional approaches. CLIP does not need training data for a specific task, it can simply summarize them.
Flamingo
Flamingo, developed by DeepMind, is a Visual Language Model (VLM). Its main purpose is to perform tasks that require understanding of visual and textual information.
Flamingo can process and generate responses based on combinations of text and visual input. This is due to its ability to integrate the capabilities of vision and language models. Because of this, Flamingo successfully handles various tasks such as answering questions about images, creating textual descriptions of visual content, and participating in dialogues that require an understanding of visual context.
CogVLM
CogVLM (Cognitive Visual Language Model) aims to improve the integration of visual and text data. It is an open-source model that bridges the gap between vision and language understanding. The model does not harm the performance of NLP tasks because it does not use the shallow alignment method, unlike traditional models. CogVLM demonstrates efficiency and performance in a variety of tasks and numerous classic cross-modal tests.
