“The development of full artificial intelligence could spell the end of the human race. It would take off on its own and re-design itself at an ever-increasing rate. Humans, limited by slow biological evolution, couldn’t compete and would be superseded.” Stephen Hawkings


While the truth in this quote by one of the prominent individuals of the century has resonated and is currently haunting many of the top practitioners of AI in the industry, let us see what stirred this thinking and persuasion. 

Well, this is owing to the recent popularity and surge in embracing the usage of Generative Artificial Intelligence (Gen AI) and the paradigm change that it has brought into our everyday lifestyle with it that some individuals feel that if not regulated, this technology can be used and manipulated to embark anguish amongst human race. So today’s blog is all about the nitti-gritties of Gen AI and how can we be both benefitted and tormented by it.


This article was published as a part of the Data Science Blogathon.

What is Gen AI?

Gen AI is a type of Artificial Intelligence that can be used to generate synthetic content in the form of written text, images, audio, or videos. They achieve it by recognizing the inherent pattern in existing data and then using this knowledge to generate new and unique outputs. Although it is now that we are using a lot of this Gen AI, this technology had existed since the 1960s, when it was first used in chat bots. In the past decade, with the introduction of GANs in 2014, people became convinced that Gen AI could create convincingly authentic images, videos, and audio of real people.

Machine Learning converts logic problems into statistical problems, allowing algorithms to learn patterns and solve them. Instead of relying on coherent logic, millions of datasets of cats and dogs are used to train the algorithm. However, this approach lacks structural understanding of the objects. Gen AI reverses this concept by learning patterns and generating new content that fits those patterns. Although it can create more pictures of cats and dogs, it does not possess conceptual understanding like humans. It simply matches, recreates, or remixes patterns to generate similar outputs.

Gen AI

Starting in 2022, Gen AI has taken the world by storm; so much so that now in every business meeting, you are sure to hear this term at least once, if not more. Big Think has called it “Technology of the Year,” this claim is more than justified by the amount of VC support Generative AI startups are getting. Tech experts have mentioned that in the coming five to ten years, this technology will surge rapidly breaking boundaries and conquering newer fields.

AI Example

Types of GenAI Models

Generative Adversarial Networks (GANs)

Gen Models

Features of GANs

  • Two Neural Networks: GANs consist of two neural networks pitted against each other: the generator and the discriminator. The generator network takes random noise as input and generates synthetic data, such as images or text. On the other hand, the discriminator network tries to distinguish between the generated data and actual data from a training set.
  • Adversarial Training: The two networks engage in a competitive and iterative negative training process. The generator aims to produce synthetic data indistinguishable from real data, while the discriminator seeks to accurately classify the real and generated data. As training progresses, the generator learns to create more realistic samples, and the discriminator improves its ability to distinguish between real and fake data.
  • Mutual Improvement: The adversarial nature of GANs leads to a mutual improvement between the generator and discriminator. As the generator learns to create more realistic data, it becomes harder for the discriminator to distinguish between actual and generated samples. This prompts the discriminator to become more discerning, pushing the generator to produce more convincing examples. GANs can achieve high-quality generation of complex and realistic data through this feedback loop.

Variational Auto Encoders (VAEs)

  • Variational Autoencoders (VAEs) are generative models that aim to learn a compressed and continuous representation of input data. VAEs consist of an encoder network that maps input data, such as images or text, to a lower-dimensional latent space. This latent space captures the underlying structure and features of the input data in a continuous and probabilistic manner.
  • VAEs employ a probabilistic approach to encoding and decoding data. Instead of producing a single point in the latent space, the encoder generates a probability distribution over the latent variables. The decoder network then takes a sample from this distribution and reconstructs the original input data. This probabilistic nature allows VAEs to capture the uncertainty and diversity present in the data.
  • VAEs are trained using a combination of reconstruction loss and a regularization term called the Kullback-Leibler (KL) divergence. The reconstruction loss encourages the decoder to reconstruct the original input data accurately. Simultaneously, the KL divergence term regularizes the latent space by encouraging the learned latent distribution to match a prior distribution, usually a standard Gaussian distribution. This regularization promotes the smoothness and continuity of the latent representation.
Gen Models

Transformer-Based Models

Gen Models
  • Self-Attention: The core component of the Transformer architecture is the self-attention mechanism. It allows the model to capture dependencies and relationships between words or tokens in the input sequence. Self-attention computes attention weights for each token by considering its interactions with all other tickets in the series. This mechanism enables the model to weigh the importance of different words based on their relevance to each other, allowing for comprehensive context understanding.
  • Encoder-Decoder Structure: Transformer-based models typically consist of an encoder and a decoder. The encoder processes the input sequence and encodes it into representations that capture the contextual information. The decoder, in turn, generates an output sequence by attending to the encoder’s terms and using self-attention within the decoder itself. This encoder-decoder structure is particularly effective for tasks like machine translation, where the model needs to understand the source sequence and generate a target sequence.
  • Positional Encoding and Feed-Forward Networks: Transformers incorporate positional encoding to provide information about the order of the tokens in the input sequence. Since self-attention is order-agnostic, positional encoding helps the model differentiate the positions of the tickets. This is achieved by adding sinusoidal functions of different frequencies to the input embeddings. Additionally, Transformers utilize feed-forward networks to process the encoded representations. These networks consist of multiple fully connected layers with non-linear activation functions. This enables the model to capture complex patterns and dependencies in the data.

Some Prominent Gen AI Products 

Some prominent Gen AI interfaces that sparked an interest include Dall-E, Chat GPT, and BARD.


Dall-E is a GenAI model developed by Open AI, that allows you to create unique and creative images from textual descriptions.

How Will Gen AI Impact Jobs?

As the popularity of Gen AI keeps soaring, this question keeps looming. While I personally believe the statement that AI will never replace humans, people using AI intelligently will replace those who don’t use AI. So it is wise not to be utterly naive towards the developments in AI. In this regard, I would like to reiterate the comparison of Gen AI with email. When emailing was first introduced, everybody feared that it would take up the job of the postman. However, decades later, we do see that postal services do exist, and email’s impact has penetrated much deep. Gen AI also will have similar implications.

Limitations of Gen AI

Reading till now, Gen AI may seem all good and glorious, but like any other technology, it has its limitations.

Data Dependence

Generative AI models heavily rely on the quality and quantity of training data. Insufficient or biased data can lead to suboptimal results and potentially reinforce existing biases present in the training data.

Lack of Interpretability

Generative AI models can be complex and difficult to interpret. Understanding the underlying decision-making process or reasoning behind the generated output can be challenging, making identifying and rectifying potential errors or biases harder.

Mode Collapse

In the context of generative adversarial networks (GANs), mode collapse refers to the generator producing limited or repetitive outputs, failing to capture the full diversity of the target distribution. This can result in generated samples that lack variation and creativity.

Computational Requirements

Training and running generative AI models can be computationally intensive and require substantial resources, including powerful hardware and significant time. This limits their accessibility for individuals or organizations with limited computational capabilities.

Ethical and Legal Considerations

The use of generative AI raises ethical concerns, particularly in areas such as deep fakes or synthetic content creation. Misuse of generative AI technology can spread misinformation, privacy violations, or potential harm to individuals or society.

Lack of Control

Generative AI models, especially in autonomous systems, may lack control over the generated outputs. This can result in unexpected or undesirable outputs, limiting the reliability and trustworthiness of the generated content.

Limited Context Understanding

While generative AI models have made significant progress in capturing contextual information, they may still struggle with nuanced understanding, semantic coherence, and the ability to grasp complex concepts. This can lead to generating outputs that are plausible but lack deeper comprehension.
