What are Different Generative AI Model Types

Now that we’ve explored how Gen AI models can help businesses, choosing suitable model types is crucial.

With numerous types of generative AI models already available online and many more in development, it may be overwhelming to try and choose the right between them without any prior knowledge.

Here’s a quick overview of different types of generative artificial intelligence models:

1. Auto-Regressive Models

These models appeared as purely predictive frameworks in the first half of the 20th century. Auto-regressive models forecast new data by regressing or returning to previous data points.

When it comes to generative AI, auto-regressive models refer to algorithms that generate new data one element at a time, with each prediction depending on previously generated elements.

2. Deep Belief Networks (DBNs)

A DBN is a generative AI model that uses unsupervised learning to calculate complex probability distributions in data.

It is built by stacking many layers of Restricted Boltzmann Machines (RBMs), simpler models invented by Geoffrey Hinton in the 1980s. This greatly enhances its performance and makes it useful for such tasks as learning patterns in data and algorithm optimization.

3. Generative Adversarial Networks (GANs)

Gans, introduced by Ian Goodfellow et al. in 2014, revolutionized the field of generic modeling. This framework involves a competition between two neural networks, the generator and the discriminator.

The generator creates new data based on existing data points, such as images, while the discriminator tries to distinguish between the original and fake data.

Through this adversarial process, GANs learn to generate highly realistic synthetic outputs.

4. Convolutional Neural Networks (CNNs)

The primary tasks of this general AI model are related to visual data and include image classification, generation, and object detection.

CNNs consist of multiple layers that learn to recognize useful sequences and their importance in the original input, which they then iterate on and build on.

5. Recurrent Neural Networks (RNNs)

One of the first-generation generative AI models from the 1980s, RNNs, was developed by John Hopfield to be capable of memorizing patterns in data and using these memories to process it.

These models are widely used in tasks where context and temporal dependencies are crucial, such as speech recognition, language modeling, and time series prediction.

6. Long Short-Term Memory Networks (LSTMs)

LSTMs are a type of RNN architecture developed to address higher-level problems. They can learn long-term dependencies in data sequences by selectively remembering or forgetting information over time.

This makes LSTMs a common gen model type for speech recognition, machine translation, and text generation.

7. Variational Autoencoders (VAEs)

VAEs first emerged in the 1990s, and since then, they have gained considerable popularity. In simple terms, VAEs are complex models with two parts: an encoder and a decoder.

These two components generate new, realistic data points from learned patterns. An encoder converts given input into a smaller and denser data representation.

It preserves only the essential features the decoder needs to successfully reconstruct the original input. All irrelevant information is discarded, which leads to VAEs' high efficiency as generative AI models.

8. Diffusion Models

Diffusion models are AI models that learn the probability distribution of data by looking at how it spreads or diffuses throughout a system.

These models have shown impressive results in generating high-quality images and videos, which are unparalleled compared to any other model type.

Diffusion models typically take much longer to train than variational autoencoders due to their large-scale architecture, so this trade-off should be considered prior to implementation.

9. Transformer Models

Transformer models, introduced by Vaswani and colleagues in 2017, have been responsible for a paradigm shift in natural language processing (NLP).

With their attention mechanisms, these models focus on the essential parts of data sequences. This enables them to process and generate coherent and contextually relevant text.

AI models like Bert and GPT are based on transformers and are capable of tasks such as text classification, translation, and text generation.

All generative AI models can be combined to leverage their strengths. For instance, businesses can use CNN to extract features from images and then pass these features to an RNN for sequence modeling on top of these extracted features, leading to more realistic data samples.
