What is Generative AI: Applications and Use Cases

The roots of generative AI can be traced back to the very beginning of AI research. The concept of machine learning emerged in 1950 paving the way for data-based algorithms. Following that, Joseph Weizenbaum develops the first chatbot in history ‘ELIZA’ in the 1960’s. The turning point started in the 2000’s. We are experiencing a massive wave of generative AI-enabled services.  Generative AI has marked its footprints in various fields like art, design, healthcare, education, consulting, and more.

Let’s get into the details of what is generative AI, use cases, applications, and risk factors. 

What is Generative AI? 

“Generative AI is not just about copying the world; it’s about understanding the world and using that understanding to create new things.” – Demis Hassabis, DeepMind, co-founder

Generative AI is a deep learning model that facilitates raw data samples to self-train and produce new data based on user inputs. It can create new conversations, images, music, video, and many more creative generative results.

Types of Generative AI 

Several types of generative AI models are commonly used in various applications. Here are a few notable ones:

1. Variational Autoencoders (VAEs): VAEs are generative models that learn the underlying distribution of input data by encoding it into a lower-dimensional latent space and then reconstructing it. They are commonly used for tasks such as image generation, data compression, and anomaly detection.
2. Generative Adversarial Networks (GANs): GANs consist of two neural networks: a generator and a discriminator. The generator generates synthetic data samples, while the discriminator learns to distinguish between real and generated samples. GANs are widely used for tasks like image synthesis, video generation, and data augmentation.
3. Autoregressive Models: Autoregressive models generate output data by modeling the conditional probability of each element given the previous elements. Examples include language models such as LSTM (Long Short-Term Memory) or Transformer models used for natural language generation and text completion.
4. Flow-Based Models: Flow-based models learn to map the input data to a probabilistic latent space using invertible transformations. This allows for efficient sampling and the generation of new data points. Flow-based models are often used in tasks like image generation and density estimation.
5. Reinforcement Learning-based Models: Reinforcement Learning (RL) can be used to train generative models that generate sequences of actions. RL-based models have been used in tasks like game playing, dialogue systems, and robotic control.
6. Evolutionary Algorithms: Evolutionary algorithms use natural selection and genetic operators to evolve a population of candidate solutions. They have been used for evolutionary art, music generation, and optimization problems.

Artificial Intelligence vs. Generative AI

Artificial Intelligence: AI or artificial intelligence is a machine-powered algorithm that is trained to perform functions associated with the human mind faster and more precisely. It collaborates with data sources and mimics human intelligence to produce content that resonates with human behavior. 

Generative AI: Now, generative AI is one step ahead of AI (artificial intelligence). AI goes deeper into generative AI. Generative AI can be considered a specific application of AI. It utilizes many of the same underlying techniques and algorithms but with a distinct focus on content creation. It does not simply mimic user inputs like the previous artificial intelligence model. Generative AI can produce absolute raw and new content. 

Text-Based Learning Models and Their Training Methods

Text-based machine learning models, such as language models, work by learning patterns and relationships within textual data to generate or understand text. They can be trained using various techniques, but one of the most common approaches is supervised learning. Here’s a high-level overview of how text-based machine-learning models are trained:

1. Data Collection: The first step involves gathering a large corpus of text data relevant to the desired task. This can include books, articles, websites, social media posts, or any other text source.
2. Data Preprocessing: The collected text data is then preprocessed to clean and prepare it for training. This can involve removing unnecessary characters or symbols, tokenization (splitting the text into individual words or subwords), and applying techniques like stemming or lemmatization to normalize the vocabulary.
3. Feature Extraction: To represent the text numerically, various feature extraction techniques can be used. For example, the bag-of-words representation assigns a unique number to each word in the vocabulary and counts the occurrences of each word in a text sample. Other approaches, like word embeddings (e.g., Word2Vec or GloVe), assign dense vector representations to words in a continuous vector space, capturing semantic relationships.
4. Model Training: Once the data is preprocessed and the features are extracted, the training process begins. Supervised learning involves training a model using labeled examples, where the input data (e.g., a sentence) is associated with a corresponding target (e.g., a sentiment label). The model is optimized to learn the statistical patterns and relationships between the input and output through an iterative process.
5. Model Evaluation and Validation: After training, the model’s performance is evaluated using a separate dataset called the validation set. This helps assess how well the model generalizes to new, unseen data and allows for fine-tuning of hyperparameters or model architecture if needed.
6. Deployment and Testing: Once the model is deemed satisfactory, it can be deployed for inference on new, unseen text data. This involves applying the trained model to make predictions or generate text based on the task it was trained for.

What are Some Shortcomings of Generative AI?

While generative AI has made significant advancements, it also has some shortcomings. Here are a few common limitations:

1. Lack of Contextual Understanding: Generative AI models can struggle with understanding context and delivering accurate responses. They often generate responses based on patterns and statistical correlations in the training data without truly comprehending the meaning or intent behind the input.
2. Over-reliance on Training Data: Generative AI models heavily rely on the data they are trained on. Biases or inaccuracies present in the training data can be reflected in the generated outputs, perpetuating existing biases or misinformation.
3. Lack of Common Sense Reasoning: Generative AI models may struggle with common sense reasoning and logical inference. They can produce outputs that are factually incorrect or nonsensical, as they do not possess real-world experiences or a genuine understanding of the world.
4. Difficulty in Handling Ambiguity: Ambiguous input can pose challenges for generative AI models. They may struggle to disambiguate and produce coherent responses, leading to outputs that are vague or irrelevant.
5. Ethical and Misuse Concerns: The power of generative AI can also raise ethical concerns. There is a risk of misuse, such as generating misleading or harmful content, deepfakes, or spam. Safeguards and responsible use of generative AI are crucial to mitigate these risks.
6. Resource-Intensive Training and Inference: Training generative AI models often requires significant computational resources and time. Additionally, generating outputs from these models can be computationally demanding, limiting their real-time applications or accessibility on low-powered devices.

ChatGPT and Its Dominance in Generative AI in 2024

ChatGPT is a language model developed by OpenAI. It was trained using Reinforcement Learning from Human Feedback (RLHF) and gained attention for its ability to generate coherent and contextually relevant responses in natural language conversations.

The history of ChatGPT can be traced back to the development of GPT-2, which was released in 2019. GPT-2 demonstrated impressive language generation capabilities, but due to concerns about its potential misuse, OpenAI initially limited its release. However, subsequent iterations and improvements led to the development of ChatGPT.

By 2023, ChatGPT has become a dominant force in generative AI. Through continuous training and fine-tuning, it has significantly improved in generating human-like responses and understanding nuanced contexts. Its widespread use in various industries, including customer support, virtual assistants, and content creation, has solidified its position as a leading language model.

How Does Generative AI Work? 

“Generative AI has the power to unlock new forms of human expression and creativity. It will push the boundaries of what’s possible and help us imagine and build a better future.” – Satya Nadella, Microsoft CEO

Generative AI produces data through the use of models that are trained on large datasets. These models, often based on neural networks, learn patterns and relationships within the data they are exposed to during the training process. Once trained, generative AI can generate new data samples that mimic the patterns of the original dataset.

Example: 

Let’s consider a generative AI model trained on a dataset of handwritten digits (0-9). During training, the model learns the features and variations present in the dataset. Once trained, it can generate new, realistic-looking handwritten digits that were not part of the original dataset.

For instance, if the model encounters a sample of the digit ‘8’ during training, it learns the typical strokes, curves, and variations associated with the digit. After training, the generative AI model could then produce new, synthetic examples of the digit ‘8’ that were not present in the original dataset.

In summary, generative AI produces data by learning and replicating patterns from the input dataset, enabling it to create synthetic data that resembles the original and can be used for various applications, including image generation, text completion, and more.

Here’s a step-by-step breakdown:

Step 1: Data Collection 

The first step is data collection. Generative AI gathers massive datasets from the existing content in the desired domain. 

The data collection process runs on a variety of sources including books, articles, websites, social media posts, and anything available in the cloud. Data preparation and cleaning are the crucial focus at this step.

Step 2: Data Cleaning and Processing

The generative AI model then identifies and collects relevant data from various sources. To bring you the best answer from the prompt, it cleans data and arranges it into a format. The process may involve converting various file formats, aligning timestamps, and ensuring proper structure. 

Then, the data goes through a few more cleaning processes like noise removal, bias detection and mitigation, consistency checks, and validation.

Step 3: Model Training

Now the actual magic begins! Here, a specific type of AI model, often a deep learning model like a neural network, is chosen.

This model is fed the prepped data and starts learning its subject matter. It analyzes patterns, relationships, and statistical probabilities within the data, understanding how words connect, images are structured, or music unfolds.

Training involves feeding the model the data repeatedly and fine-tuning its internal parameters through algorithms like backpropagation to minimize errors and improve its learning.

Step 4: Content Generation

“Generative AI is the future of content creation. It will democratize the ability to create high-quality content, making it accessible to everyone.”- Andrew Ng, Landing AI founder

Once trained, the model is ready to create! You provide it with a prompt or seed, which can be a text phrase, an image sample, or any relevant input in the chosen domain. The model then leverages its previously learned knowledge to generate new content. 

This generation process can be iterative, with the model refining its output based on feedback or additional inputs. It leads to increasingly personalized results.

Step 5: Content Refining and Optimizing

Generative AI isn’t a one-and-done process. The models and generated content are constantly evaluated for accuracy, quality, and desired originality. If you make even minor changes to your prompt, generative AI might produce very different results compared to the previous. 

Techniques like human validation, comparison with ground-truth data, and error analysis are used to identify areas for improvement. Based on these evaluations, the model can be further trained with additional data or adjusted in its parameters to generate better outputs over time.
