Generative AI can produce excellent results, but it still needs human help at the beginning and end of the training process to get the best results. Human input is needed to provide the first data set, determine which features are essential for the model to learn, and review the results for quality and relevance. When human and machine intelligence works together, as in generative AI, it opens up a whole new world of content-making options.
In this guide, we'll show you the basics of generative AI, how it works, and some of the cool things that will be possible with it.
What is Generative AI?
Generative AI is a group of techniques and models for artificial intelligence used to make new, original material. It includes using algorithms for machine learning to find patterns and structures in existing data and then using that information to make new data that looks like the original.
Generative AI models can make pictures, music, text, and videos. These models are often built on deep learning architectures, such as generative adversarial networks (GANs) or variational autoencoders (VAEs), which can learn complex distributions and create realistic samples.
One of the most essential things about creative AI is that it can make new and different things. These models can create new instances with similar traits by figuring out the underlying trends in the training data. But generative AI can also make changes and be creative, leading to results that may not have been in the original collection.
Generative AI has many uses, such as making creative material, adding to data, simulating, and sometimes helping people solve problems and make decisions. It has been used to make realistic images, music, and talks between people, among other things.
A Brief History of Generative AI
Generative AI has been around for a long time, and its past is full of important milestones and breakthroughs. Here's a quick summary of how it has changed:
1. Early Years: From the 1950s to the 1970s, the first steps towards generative AI were taken. Alan Turing and John von Neumann looked into machines that could be creative like people. Turing developed the "Turing Test" to see if a machine can behave like an intelligent person.
2. Neural Networks and Autoencoders (1980s-1990s): During this time, neural networks became more famous. Researchers played with autoencoders, a neural network that tries to learn compact representations of incoming data. Even though autoencoders were not directly generative, they set the stage for later generative models.
3. Restricted Boltzmann Machines (RBMs) and Deep Belief Networks (2000s): RBMs are a generative model that emerged in the early 2000s. They made it possible to simulate complicated distributions and make new samples. Deep belief networks (DBNs) were based on RBMs and made it possible to create more accurate samples.
4. Generative Adversarial Networks (GANs): Ian Goodfellow and his friends developed GANs, which changed generative AI. GANs have two neural networks: a generator network that makes samples and a discriminator network that learns to tell the difference between actual and made samples. GANs have successfully made realistic pictures, and their design has been used in other areas.
5. Variational Autoencoders (VAEs): Diederik P. Kingma and Max Welling developed VAEs in 2014. They are a well-known generative model. VAEs mix the encoding and decoding abilities of autoencoders with probabilistic modeling. This makes it possible to create samples that are different from each other.
6. Recent Improvements and Applications: Creative AI has made much progress in the last few years. Researchers have examined more complicated architectures, better training methods, and applications in different areas. People have used generative models to create images, writing, music, videos, and even deepfakes.
Different types of Generative AI models
There are different kinds of generative AI models, each with its way of working and traits. Here are some of the most common:
1. Generative adversarial networks (GANs) have two neural networks: a generator and a discriminator. The generator makes fake data samples, like pictures or text, while the discriminator decides if the samples are actual. The two networks are trained in a way that makes them compete. The generator aims to make samples that can't be told apart from accurate data.
2. Variational Autoencoders (VAEs): VAEs are probabilistic models that combine autoencoders and variational inference methods. They have an encoder network that maps data input to a "latent space" and a "decoder network" that takes data from the "latent space" and puts it back together. VAEs learn a probability distribution over the latent space, which lets them take samples from that distribution to make new samples.
3. Autoregressive models are based on the idea that you can model the conditional chance of each item in a sequence based on the items that came before it. These models make data one piece at a time, with each piece depending on the ones that came before it. PixelCNN and WaveNet are two examples of autoregressive models used to make images and sounds, respectively.
4. Transformer-based models: Transformer models were first made for natural language processing jobs but have also been used to make new things. These models use self-attention processes to determine how different parts of the input data depend on each other. They have been good at making text, translating it, and making images from scratch.
5. Flow-based Models: Flow-based models aim to learn a bijective relation between an input distribution and a target distribution. They are taught to use several transformations that can be used in either direction to change a simple distribution, like a Gaussian distribution, into the target distribution. Flow-based models are known for their ability to make high-quality samples and do accurate likelihood estimations.
6. Models that use reinforcement learning: The generation process can be modeled as a series of decisions that need to be made for reinforcement learning to be used to train generative models. These models are taught by giving them rewards or other signs showing them what to do to get the desired results. Combining reinforcement learning with other generating models, like GANs or VAEs, can improve the quality of samples.
How does generative AI work?
Generative AI works by using machine learning algorithms to learn patterns and structures from existing data and then using that knowledge to create new data that looks like the original. Here is a summary of how generative AI usually works:
1. Data Collection and Preprocessing: The first step is to collect extensive data representing the data you want the generative model to produce. This set of info could be pictures, words, music, or anything else. The data is cleaned, normalized, and changed into a version that can be used for training. This is called "preprocessing."
2. Model Architecture Selection: Pick the exemplary generative AI model architecture based on your desired data and results. Different models, like GANs, VAEs, autoregressive, and transformer-based models, learn and make data differently.
3. Training: The collected information is used to teach the chosen model. During training, the model learns the data's basic patterns, structures, and statistical distributions. The training process is different for each type of model and design.
4. Sampling and Making: After the model has been trained, it can make new data samples. In most cases, selecting from the model's learned distribution is the best way to get new data. The exact way of picking depends on the type of model. For example, in GANs, random noise is fed into the generator network to make examples. In VAEs, samples are made by taking random samples from the latent space that has been learned.
5. Evaluation and Iteration: The samples made are judged based on specific metrics or criteria, such as their quality, how close they are to the training data or the properties that are wanted in the samples. If the generated samples don't meet the desired criteria, the model can be improved by changing the training method, architecture, or data gathering.
The quality and variety of the training data, the model architecture, the training process, and the evaluation factors all affect how well generative AI works. The area of generative AI is constantly changing, and researchers are always looking for new models and methods to improve the quality and variety of the content that is made.
Role of natural language processing in Generative AI
Natural Language Processing (NLP) is integral to generative artificial intelligence, especially when making text-based material. Here are some of the most critical ways that NLP helps creative AI:
1. Text Generation: NLP methods are often used in generative models to make text that looks like a person wrote it. Models like recurrent neural networks (RNNs) and transformer-based designs, like the GPT (Generative Pre-trained Transformer) models, use NLP techniques to learn the statistical properties of text data and create coherent and appropriate text sequences.
2. Modelling Language: Language models are essential to creative AI. They learn words' structure, grammar, and meaning by reading a lot of text. Like the GPT models described above, language models can predict the next word in a sentence or make up a text based on a prompt.
3. NLP is a crucial part of making conversational agents or chatbots. Generative AI models for conversation systems use NLP to understand what the user is asking, develop the correct answers, and keep the context clear. These models use natural language (NLU) methods to understand what the user wants and develop answers that make sense and fit the situation.
4. Language Style Transfer: NLP moves a text's style or tone to another text while keeping the information the same. This method can make text in a specific writing style or change text to match a particular tone. NLP models can pick up on style-related details and use them to make text with the right qualities.
5. Machine Translation: NLP methods are essential for generative AI models used in machine translation. To correctly translate between languages, these models learn the statistical properties and semantic relationships of text in different languages. NLP methods are used in techniques like neural machine translation to understand source text, make intermediate representations, and translate source text into the target language.
6. Text Summarization and Generation: In generative models, NLP techniques summarise long texts or make short summaries. These models can figure out what's essential in a text and make an outline that hits on the main points. NLP tools like attention mechanisms and encoder-decoder structures help make summaries that are clear and full of helpful information.
