Introduction to Generative AI


To begin, Generative Artificial Intelligence (Generative AI) is the type of AI that can generate high quality, original content. It stands at the forefront of cutting-edge technology. Generative AI is evolving with the development of generative adversarial networks. Let’s understand Generative AI and its working process.

What is Generative AI?

Generative AI is a subset of artificial intelligence that focuses on creating new data. It is trained to generate new data samples based on patterns from existing data. Generative AI mimics human creativity and generates realistic output.

How Generative AI Works?

The main focus of Generative AI are generative models, which generates new content in various forms. The generative models are based on:

  • Neural networks
  • Deep learning techniques.

Neural networks are computational systems and Deep learning is a subset of machine learning. These are involved in learning to recognize patterns and generate content.

Model Architecture:

Generative AI models use specific architectures, such as:
  • Generative Adversarial Networks(GANs)
  • Transformers
  • Variational Autoencoders(VAEs)

Generative Adversarial Networks(GANs)

The most popular approaches to Generative AI is the Generative Adversarial Network (GAN) which consists of two neural networks:

  • Generator: To create new data
  • Discriminator: Evaluates the data.

The generator and discriminator train together to produce increasingly realistic output.


To generate coherent and contextually relevant text, Transformers consists of: Encoder: To process the input sequence and generate a set of representations. Decoder: Generating the output sequence from the encoded representations. These models use attention mechanisms to weigh the importance of different words in a sentence. GPT, BERT, and T5 are examples of transformer-based models.

Variational Autoencoders(VAEs)

VAE models are used to generate new, similar data. These models learn to encode data into a latent space and then decode it back to its original form. VAE consists of:

Encoder: This network maps the input data to a latent space.

Latent Space: Mapping the input to a distribution.

Decoder: Maps the points from the latent space to the data space for reconstructing the input data.

Steps followed by Generative models

The necessary steps involved in creating new content by generative models are:

Training data:The generative models are trained on large datasets. It helps to learn the structure and the information about the data.

Pre-training: Initially trained on the model using a broad dataset in an unsupervised manner. This helps to learn general patterns and structures in the data.

Fine-tuning: The pre-trained model is then fine-tuned on a specific dataset or task in a supervised manner. This step helps the model specialize on particular tasks.

Generating Process: During the generation of new content, the model takes a prompt or starting point. It uses the patterns it learned during training to create new data.

Evaluation and Iteration process: The output of generative AI models are evaluated using various metrics based on input constraints. The feedback from these evaluations is used to iteratively improve the model. The metrics used for evaluation are:

  • coherence,
  • relevance,
  • creativity,
  • adherence.

Applications of Generative AI:

The Various applications of Generative AI are:

Natural Language Processing: Generative AI models can generate human-like text. It enables applications such as language translation, content generation, and question answering.

Art and Design: Generating novel artworks, designs, images, music and animations. Artists and designers can explore new aesthetic possibilities and push the boundaries of creativity.

Media and Entertainment: To produce synthetic content like virtual actors and generated game environments. It enhances storytelling and immersive experiences.

Healthcare: Promising applications like: drug discovery, molecular design, medical image synthesis and personalized treatment planning.

Fashion and Retail: To create virtual try-on experiences, personalized fashion recommendations Designing bespoke clothing based on individual preferences.


To sum up, Generative AI represents a paradigm shift in artificial intelligence. It enables machines to understand, manipulate and create entirely new content. As the field continues to advance, the possibilities for innovation and creativity are limitless.
