Guide: How Does Generative AI Work?

Have you ever wondered how computer programs can generate diverse types of content like images, music and video?

That's thanks to an increasingly popular subfield of Artificial Intelligence (AI) called Generative AI.

This article will take you behind the scenes to explain how these models learn from existing data.

Buckle up and get ready to discover the practical applications of GenAI!

What is Generative AI?

Generative AI is a subset of Artificial Intelligence that can create "original content", including images and 3D models, by learning from massive amounts of data.

GenAI leverages advanced Machine Learning models and Neural Networks (NNs) to identify data patterns and structures, allowing it to generate realistic outputs.

These models have a wide range of applications, including drug discovery, Natural Language Processing tasks and promotional content creation.

What sets GenAI models apart is their ability to process vast amounts of info and then use it to generate content that closely resembles real-world creations.

Whether it's a new melody for a song or a photorealistic image of a landscape, generative models can produce results that are often indistinguishable from human-created content.

How Does Generative AI Work

How Does Generative AI Work?

1. Creation

Neural Networks are complex systems inspired by the human brain— they consist of interconnected nodes known as “artificial neurons.”

These networks are the foundation of GenAI, where NNs are trained on large datasets to identify patterns and relationships within the data.

Among advanced types are Generative Adversarial Networks (GANs), diffusion models and Transformer-based Models.

In a Neural Network architecture, each layer is designed to learn to extract increasingly complex features from the input data.

For example, in image recognition, early layers might detect simple elements like edges, and deeper layers identify complex shapes and objects.

This layered structure allows the network to capture the subtleties and nuances of the data it processes.

Deep Learning (DL) also plays a crucial role, allowing the AI to refine its output through multiple layers of processing. 

2. Training

GenAI models thrive on extensive training as they're fed on enormous datasets—images, text, audio—to understand their underlying patterns.

The larger and more varied the data, the better the generative model grasps these patterns and generates realistic and diverse outputs.

During training, the Neural Network analyzes the data to identify recurring patterns and statistical distributions.

Fun fact: During training, GenAI models like GANs use two Neural Networks—generator and discriminator—where one creates new content and the other improves it.

It goes to encode these patterns into internal parameters, essentially compressing the acquired knowledge, which becomes the foundation for generating new content.

3. Generation

Once trained, the model uses its learned knowledge to create new and original content. 

It does so by sampling from the probability distribution it has learned from the training data, generating outputs that are statistically similar but with subtle variations and fresh combinations.

For example, if you show the model thousands of Van Gogh paintings, it can learn his distinctive style, including his brushstrokes, colors, and swirling patterns.

As a result, it can create new paintings that capture his essence, even though they are entirely original.

4. Optimization

To enhance the quality and diversity of its creations, Generative AI models often undergo fine-tuning and optimization.

Fine-tuning involves additional training on a smaller, more specific dataset to tailor the model to a particular style or domain, such as making a Language Model generate more formal text.

Algorithm optimization, on the other hand, enables the adjustment of internal parameters based on human feedback or evaluation metrics, guiding it toward producing increasingly impressive results. 

This ongoing refinement helps the model generate more realistic, coherent, and high-quality outputs.

Advances in Machine Learning models also ensure that AI-generated content increasingly mirrors the nuanced complexity of human-created content.

However, we can't understate the importance of human labor. GenAI tools can ease and improve our lives, but they can only provide us real value as long as there are professionals who can harness their full power.

"At Capicua, we have decided to develop products with Generative AI for multiple reasons. We always strive to be at the forefront of technology and explore the full potential that GenAI offers! This not only allows us to innovate but also to understand better how to apply this technology to solve real problems and bring effective solutions to our customers and users." — Juan Diego Mendez, Technical Lead @ Capicua.

Generative AI Applications

GenAI in Finance

Generative AI has emerged as a powerful tool for risk assessment and fraud detection in the financial sector

AI models can analyze large amounts of historical and real-time transaction data to uncover subtle patterns and anomalies indicative of fraudulent activity. 

For example, Mastercard is leveraging GenAI to strengthen fraud detection, resulting in better anomaly detection in suspicious transactions.

GenAI can also play a major role in investment management, as it can generate synthetic market data, simulate scenarios, and analyze financial instruments to help investors identify potential opportunities and risks. 

JPMorgan Chase is one of the frontrunners in leveraging Generative AI to enhance its trading strategies and portfolio management.  

In customer experience, GenAI chatbots can offer personalized financial advice and assistance, handle routine inquiries and free up human advisors to focus on more complex needs. 

Bank of America's Erica virtual assistant exemplifies these capabilities, providing 24/7 support and personalized financial guidance.+

GenAI in Retail

By analyzing user data, AI models can generate highly targeted marketing campaigns and push products for each customer, leading to higher conversion rates and improved customer loyalty. 

Stitch Fix, an online personal styling service, uses Generative AI to curate personalized clothing recommendations for its clients, driving customer satisfaction and retention.

In addition, retailers can leverage Generative AI for inventory optimization and supply chain management

By forecasting demand and predicting disruptions, AI models enable retailers like Walmart to maintain optimal inventory levels, reduce costs, and ensure timely product availability.

Further, GenAI is transforming Product Design in the retail sector, as it can generate product concepts, simulate reactions and create virtual prototypes to significantly reduce time-to-market. 

Nike uses Generative AI in footwear design, from the initial product concept to hundreds of AI-created variations that are refined into prototypes that meet its standards. 

Roger Chen, VP of NXT Digital Product Creation, states that creating starting points for their products used to take months, but it takes seconds using GenAI.

GenAI has the potential to inspire creativity and innovation in Product Design and Development!

Conclusion

Generative AI is a significant advance in the field of Artificial Intelligence, offering immense potential for creating original and realistic content.

Its ability to learn from vast amounts of data and generate new outputs has potential applications for several industries, such as FinTech and Retail.
