Types of generative AI models

A variety of generative AI models exist, each employing distinct methodologies and serving different purposes. Among the frequently used models are:

Generative Adversarial Network (GAN) – GANs, or Generative Adversarial Networks, represent a type of deep learning architecture designed to produce new data that mimics the original training data. They have found successful applications across various domains, including text generation, music creation, and image generation. A GAN comprises two competing neural networks: the generator, which creates new content that resembles the source data, and the discriminator, which evaluates the content and distinguishes between the real input data and the generated output. This interaction fosters improvement in the quality of the generated data. GANs are particularly effective in generating high-quality images and videos, demonstrating remarkable capabilities in producing lifelike visuals, crafting animations, and even generating synthetic human faces. Beyond visual applications, they are also being explored in fields such as natural language processing, music production, and fashion innovation.

Transformer-based models – Transformer models are predominantly applied in natural language processing tasks, including language translation, text generation, and summarization. They utilize a self-attention mechanism that enables the model to consider all words in an input sequence at once, thereby effectively capturing long-range dependencies and contextual relationships, surpassing the capabilities of traditional NLP models. A notable application of the Transformer model in generative AI is its role in language translation. By adeptly identifying intricate linguistic patterns and subtleties, the Transformer model proves to be an essential instrument for producing high-quality text across diverse contexts.

Variational Autoencoder (VAE) – Variational Autoencoders are generative deep learning models utilized primarily for unsupervised learning tasks. They merge the principles of autoencoders with probabilistic modeling to capture the underlying structure and distribution of a dataset effectively. The encoder component transforms input data into a lower-dimensional latent space, while the decoder reconstructs the original data from this latent representation. VAEs aim to minimize two key objectives: reconstruction loss, which measures how well the model can recreate the input data, and regularization loss, which ensures the latent space follows a specific distribution. By sampling from this learned latent distribution, VAEs can generate new data samples. Their versatility allows for applications in various domains, including image and text generation, as well as data compression, making them a robust framework for generative modeling and representation learning.

Autoregressive Models – Autoregressive models are a type of generative AI that utilize probability distributions to create new data sequentially. These models generate content one element at a time, leveraging previous elements to inform the generation of the entire dataset. Commonly, they are used to produce sequences of text, audio, or images. For example, a language model may be trained to predict the probability of each subsequent word in a sentence based on its preceding words. The process starts with an initial word or phrase, and the model relies on its predictions to iteratively generate the next words. Recurrent Neural Networks (RNNs) are often employed to build autoregressive models. These models are particularly prevalent in natural language processing and speech recognition, as well as in generating images and videos, where each new frame is based on the preceding frames.

Boltzmann Machines – A Boltzmann Machine is a type of generative unsupervised model that learns the probability distribution of a specific dataset, enabling it to make predictions about unseen data. These machines are composed of binary units interconnected through weighted links. As generative models, Boltzmann Machines can produce new data samples by sampling from the probability distribution they have learned. This capability allows for a range of applications, including image and speech recognition, anomaly detection, and recommendation systems.

Flow-based Models – Flow-based generative models are highly effective tools for generating realistic and high-quality data samples. Their increasing popularity can be attributed to their ability to manage substantial datasets, produce exceptional content, and perform efficient inference tasks. Compared to other types of generative AI models, flow-based models offer significant advantages, as they can effectively handle high-dimensional input while generating quality samples without the need for adversarial training. Additionally, they enable direct computation of the probability density function, allowing for efficient inference. Nevertheless, these models may face limitations in adaptability when it comes to simulating complex distributions, and they can be computationally intensive to train, especially with intricate datasets.

How generative AI models work? The step-by-step process

Generative AI models operate by examining the patterns in a vast dataset and leveraging this understanding to create new content. This process can be delineated into multiple key steps.

  • Data Gathering: The initial phase involves collecting a large dataset that serves as the foundation for the generative model’s learning. This dataset can encompass various forms such as images, audio, text, or other relevant data types.
  • Preprocessing: Following data collection, it is essential to preprocess the information. This step entails cleaning the data to eliminate errors and structuring it in a way that is comprehensible for the model.
  • Training: The next step is to train the generative AI model using the preprocessed data. During this phase, machine learning algorithms analyze the data to identify patterns and relationships, enabling the model to learn how to generate new content.
  • Validation: Once training is complete, the model undergoes validation to ensure it produces high-quality outputs. This involves testing the model on an independent set of data and evaluating its performance and accuracy.
  • Generation: After successful training and validation, the model is ready to generate new content. This is achieved by providing a set of input parameters, which the model uses in conjunction with its learned patterns to create outputs similar to the training data.
  • Refinement: Finally, human experts may refine the generated content, which may include selecting the best outputs or making minor adjustments to align with specific criteria or requirements.

Training generative AI models: Best practices and techniques

  • Generative Adversarial Networks (GANs): Training a GAN involves simultaneous training of two networks: the generator and the discriminator. The generator creates samples, while the discriminator evaluates the authenticity of these samples against real data. This iterative process updates both networks alternately to enhance the generator’s ability to produce realistic outputs and the discriminator’s ability to differentiate between genuine and generated samples, striving toward a Nash equilibrium.
  • Variational Autoencoders (VAEs): A VAE is trained by encoding input data into a compressed latent space through an encoder network and then decoding it back into the original space with a decoder network. The training is guided by a variational lower-bound objective, which optimizes both the reconstruction loss and a KL divergence term that ensures the latent space approximates a standard normal distribution. Techniques such as backpropagation and stochastic gradient descent are commonly used for optimization.
  • Autoregressive Models: These models predict the probability distribution of the next item in a sequence based on previous items. They are trained using maximum likelihood estimation to minimize the negative log-likelihood of training data. The loss is measured by comparing the expected probability distribution against the actual distribution, with parameters updated through backpropagation across time to refine predictions.
  • Boltzmann Machines: Training is accomplished via the Contrastive Divergence algorithm, which adjusts the weights of binary connections iteratively based on the difference between real and generated samples. The process involves using training examples to maximize the likelihood of the input data until the model reaches convergence.
  • Flow-based Models: These models utilize maximum likelihood estimation to align their probability distribution with that of the training data. The training involves inputting a series of data points and determining the loss by comparing the predicted probability density function with the actual one, followed by parameter updates through backpropagation.

Evaluating generative AI models: Metrics and tools

Evaluating generative AI models plays a crucial role in the development phase, as it allows for the assessment of the model’s quality and effectiveness. The evaluation methodology can differ significantly based on the particular type of generative AI model implemented.

  • GANs: Generative Adversarial Networks (GANs) are assessed using the Frechet Inception Distance (FID), which measures the similarity between generated images and real images. The FID metric leverages a pre-trained classifier network to compare the distributions of both sets of images in a feature space, with lower FID values indicating better performance.
  • VAEs: Variational Autoencoders (VAEs) are evaluated primarily through reconstruction error and sample quality metrics, including the Inception Score and FID. These metrics assess the model’s effectiveness in reconstructing original data and producing high-quality samples. Generally, a combination of both quantitative and qualitative metrics is utilized for a comprehensive evaluation.
  • Autoregressive Models: The evaluation of autoregressive models focuses on their predictive accuracy in forecasting the next item in a data sequence, typically using perplexity as a metric. Perplexity represents the negative log-likelihood of test data normalized by the word count, with lower scores indicating a model’s reduced confusion and enhanced predictive capability regarding the sequence’s underlying structure.
  • Boltzmann Machines: Boltzmann machines are primarily evaluated using log-likelihood, which assesses their ability to generate data similar to the training data. The log-likelihood is determined by calculating the log probability of the test data under the model, with higher values corresponding to superior performance.
  • Flow-based Models: The performance of flow-based generative models is evaluated by calculating log-likelihood estimates for their generated samples. Techniques such as importance sampling or maximum likelihood estimation are employed to quantify the models’ effectiveness against the specified dataset.
