Generative AI

Generative AI is an artificial intelligence (AI) technique that uses deep learning and natural language processing (NLP) to categorize, translate and summarize input data and produce synthetic content. The generative AI-powered software can bulk produce images, videos, photorealistic visuals, deep fakes, or audio recordings.

The revelation in artificial general intelligence (AGI) has powered computing systems with emotional intelligence or human-like intelligence that resembles the thought process of a working human brain.

A generative AI model works on the ground of an artificial neural network known as a transformer. 

Transformers are recently built semi-supervised models trained on large volumes of data. With another additional technique of "attention," the algorithm builds bridges between different syllables, words, and sentences. The system then derives readable content as output.

Types of generative AI models

Researchers believe that modern kinds of generative AI models have the potential to make it big in the technology industry. Replicating human think tanks and processing quick content can be expected out of these newer kinds of deep learning models. 

Here are a few common generative AI models that are being used as business tools:

• The diffusion model, also known as the denoising diffusion probabilistic model (DDPM), is a two-step process model. It works on forwarding data and reversing noise. The feed-forwarding process adds noise, while the latter reduces it to produce novel output.
  

• Variation autoencoders and decoders decode input tokens and encode them based on positional information and sequence number. The input is converted into a simple vector, which is bound by other such vectors of tokens in a sentence. Once the data goes through encoders, decoders recieve it, unmask it and predict the best course of output. 
  

• Generative adversarial networks are trained on two neural networks (generator and discriminator) simultaneously. While one neural network acts as a generator that produces new output, the other distinguishes it from the human text.
  

• Transformers networks work on principles of positional encoding, self-attention or multi-attention, and decoders to address sequential input and create inferences between words of sentences. It tries to understand "subject-to-verb" agreement between words and passes it through several layers to derive output.
• Neural network radiance field (NeRF)  is used to build AI art generators and produces 3D vectors for 2D images using advanced machine learning. It involves encoding the entire object in the neural network, spotting light intensity, and creating 3D views from different angles.
  

• GenAI ecosystem: GenAI is a new community-driven initiative by Microsoft to create pitch-perfect content without human support. It aims to integrate generative AI into its Azure Open AI service, Microsoft 365 Dynamics CRM, and  to understand its audiences and their sentiments better. 

How does generative AI work?

The early instances of generative or conversational AI can be found in voice assistants like Google Home, Apple’s Siri, or Microsoft Cortana. However, most relied on a support vector machine (SVM) classifier to capture, categorize, and execute voice data. In generative AI, machine learning algorithms are trained on labeled and unlabelled datasets. 

Generative AI tools are trained on such large language models (LLMs) that scrape off a surplus of data from the internet. The model is trained on quality data from articles, blogs, encyclopedias, and image art galleries. 

As the system receives an input, it reinforces the neural network. The neural network accepts it through the input layer and compares it with the underlying training dataset. Once there is a data match, it sends the data to LLM. As the LLM  generates a singleton word or a sentence, the neural network works responsively to generate the following follow-up words or sentences.

Applications of generative AI

Gen-AI has passed off as a recently discovered breakthrough in commercial and non-commercial industries. From automotive to healthcare to medtech to aeronautics, generative AI is being used to create models and augment computing to achieve safe outcomes. 

Among all the industries accepting generative AI, a few are:

• Image recognition: With high-end predictive modeling, generative AI models can identify missing parts of an image, adjust backgrounds, set illumination, fix torn or chipped images and create one from scratch.
• Nanotechnology: Self-assist microbial robots like nanobots are regarded as a painless way to cure terminal diseases like cancer. These self-programmed, molecule-sized bots have the potential to detect impacted human tissues and release antibiotics.
• Gaming simulation in virtual reality: These systems can predict the next moves of a gaming character in a virtual reality ecosystem and direct your counter moves accordingly.

• Video characters:  The platform helps you design 3D models, characters, gamified avatars, and much more to include in your video clips. By understanding a video's temporal or spatial elements, it can also build new videos without any external video editing tool.

• AI-generated music: Without sound mixers and audio recording support, AI music generators can record, compose and save music. It accesses audio and video files from streaming platforms to understand modes, pitch, and notes and create symphonies.

• Text-to-speech generators: A GAN-based TTS generator can convert text into high-quality audio. This is mostly used in interactive voice responses (IVRs), speech-to-text interfaces, and assistive technologies.
  

• AI-generated text: Generative AI chatbots or text generators are able to simulate human thought processes, train online data and automate content creation. Based on user prompts, it searches for relevant input data and outputs a perfectly relevant answer. 

Examples of generative AI tools

The recent tools use human-like simulation and cater to the daily needs of their businesses and other large-scale commercial entities. Some of them are:

• ChatGPT: ChatGPT is a conversational, NLP-based chatbot that helps automate long-form and short-form document creation. The query-based model responds to a reader prompt or query and generates slick and concise content. It is based on a generative pre-trained transformer (GPT) and LLMs.
  
• Bard: Bard is an AI conversational service by Google, Inc. It can detect search patterns and align them with the user’s search query to help get the best responses. The tool is programmed with an LLM known as LamdaAI.
• Alphacode: Alphacode is an AI code generator that builds responsive code repositories for coders. It is trained on massive LLMs and has NLP-based add-ons to filter, proofread, and execute the exact code user wants.
• Github Copilot: Github Copilot is an AI-text generator created by OpenAI for Github. This plugin is used by data scientists, machine learning developers, and students to create automated code threads and find answers to their recurring questions.

• GPT-4: GPT-4 is a multimodal AI model that accepts, processes, and generates all forms of synthetic media. GPT-4 model is costlier than GPT-3 but is used to recalibrate model responses, generate different output variations or add more features and plugins for businesses.

Benefits of generative AI

Generative AI has enabled businesses to reimagine their goals in a new light. With the recent innovations of generative adversarial network (GAN) powered APIs, the burden on data science and machine learning teams has significantly reduced. 

The processing powers of neural networks and data storage capabilities of computing systems are already benefiting the industry in the following ways:

• Automate monotonous jobs: Training large learning models instead of actual human staff has helped organizations minimize hiring. Most of the content in commercial domains is now being created with the help of AI models. Apart from expert-based or philosophical content, generative AI can create almost any form of content like emails, essays, articles, and blogs.

• Ad-hoc tasks: The content marketing and design teams use generative AI art generators or text generators to shift quick gears. Urgent content projects can be easily completed within a predefined deadline. Even though the content is produced quickly, generative AI tools don’t compromise quality.

• Image generation and user experience (UX): Most AI text generators are able to decode user image specifications and create descriptive narrations. It understands user demands and gives suggestions to improve UX, which saves time.

• AI maturity: AI systems with high graphical computational power can operationalize existing IT infrastructure. The newer neural network algorithms reduce the tendency of bias and cloning and focus on more accurate predictions. 
• Object detection: Generative AI algorithms are also used to understand image pixelation, background, and luminosity to detect unlabelled external objects.
• Educational content: As these models are trained on a dataset of human demonstrations and research content published by scientists and developers, they can help students in schools and colleges learn faster than traditional whiteboard teaching.
• In-depth statistical reports: Generative AI can collect facts, findings, numbers, and statistics from the internet to create in-depth reports. With prompt engineering and chain of thoughts technique, it learns patterns from input prompts and lays out multiple steps of calculations to get better at analytics and reasoning.

Limitations of generative AI

The pitfalls of deep learning fall through the cracks of the success of generative AI. The requirement for specialized systems and trained personnel remains a challenging problem on the road to generative AI automation.  

• Cost: Operationalizing your business workflows with AI can be a costly affair. While AI software has pricey plans, it also requires large computational capacities (or GPU) along with cloud computing, MLOps, and high network bandwidth.
  

• Algorithmic bias:  Generative AI models are not 100% accurate and can result in an algorithmic bias. It means the system can assign weighted parameters to a wrong set of outputs and make inaccurate predictions.
  

• Overfitting: Overfitting data in certain scenarios can result in erroneous output. Some professionals think more training data will help algorithms learn new data faster. But, only a certain amount of data creates a good fit model.
  

• Time: Working on generative AI can drain your implicit costs like time and labor. Validating, retraining, and testing these models takes up a lot of time for machine learning engineers.

• Data quality: GAN relies on high-quality data to make accurate predictions. The data should be accurate and clean and should not have any outliers or incorrect values or data.
  

Generative AI vs. predictive AI

Predictive AI is a predecessor to generative AI. This concept was invented before generative AI came into action.

Predictive AI is a technique to analyze patterns in historical data and use it to forecast outcomes. It checks for type 1 and 2 alpha, confidence score, and multicollinearity to produce a good fit model. It uses statistical analysis, regression analysis, and machine learning models to extrapolate results. 

Generative AI is based on generative adversarial networks, which is a science of training two neural networks together to identify data structure and patterns and generate content. It relies on existing data to create co-relations, break down sentiment, and creates human-worthy content.

Generative AI simulates human intelligence and quickens the pace of manual tasks.
