Current Challenges with Real Data: Why You Need Generative AI and Synthetic Data
Data is the fuel of AI. Without data, AI models cannot learn, improve, or perform. Data is also the key to unlocking the value and potential of AI for your business, industry, or domain. Data is everything.
But not all data is created equal. Real data, or data that is collected from real sources, such as sensors, surveys, or social media, has many limitations and challenges that can affect the quality and usability of your data and the development and performance of your AI solutions.
Some of these challenges are:
- Regulations: Real data is often subject to strict rules and regulations, such as GDPR, HIPAA, or CCPA, that aim to protect the privacy and security of data subjects and data owners. These regulations can limit the access, sharing, and processing of real data, especially sensitive data, such as personal, medical, or financial data. They can also impose hefty fines and penalties for non-compliance or data breaches.
- Sensitivity: Real data is often sensitive and confidential, meaning that it contains information that can identify, harm, or discriminate against data subjects or data owners, such as names, addresses, phone numbers, email addresses, credit card numbers, health records, or biometric data. This data can be vulnerable to hacking, theft, or misuse, and can cause serious damage or loss to data subjects or data owners, such as identity theft, fraud, or blackmail.
- Cost: Real data is often expensive and time-consuming to collect, store, and process, especially large-scale, high-quality, and diverse data. You need to invest in data collection methods, such as sensors, cameras, or surveys, data storage systems, such as databases, servers, or clouds, and data processing tools, such as software, hardware, or algorithms. You also need to pay for data maintenance, such as cleaning, labeling, or updating, and data security, such as encryption, authentication, or backup.
- Scarcity: Real data is often scarce and insufficient, meaning that it does not cover all the possible scenarios, variations, or outcomes that you need for your AI solution. You may not have enough data, such as samples, features, or labels, to train, test, or validate your AI model. You may also not have the right data, such as relevant, representative, or balanced data, to reflect the reality, diversity, or complexity of your problem.
Use Cases of Generative AI and Synthetic Data Across Industries
As we have seen in the previous section, real data challenges can affect the quality and usability of your data and the development and performance of your AI solutions. They can also limit the possibilities and innovations that you can achieve with AI in different domains.
But don’t worry, generative AI and synthetic data are here to help. Generative AI and synthetic data can help you overcome the real data challenges and enable new possibilities and innovations in different domains. They can help you create new and original data or content that mimics the characteristics and features of real data, without the limitations and challenges of real data.
How can they do that? Well, generative AI and synthetic data use various models, methods, and techniques to generate realistic and diverse data or content, such as images, text, audio, or video, from existing data or content, such as images, text, audio, or video, or from scratch, such as noise, vectors, or rules.
Some of the most popular and powerful generative AI models are:
- Generative Adversarial Networks (GANs): GANs are a type of neural network that consists of two competing networks: a generator and a discriminator. The generator tries to create fake data or content that looks like real data or content, while the discriminator tries to distinguish between real and fake data or content. The generator and the discriminator learn from each other and improve over time, until the generator can produce realistic and diverse data or content that can fool the discriminator.
- Variational Autoencoders (VAEs): VAEs are a type of neural network that consists of two parts: an encoder and a decoder. The encoder takes real data or content as input and compresses it into a low-dimensional representation, called a latent vector. The decoder takes the latent vector as input and reconstructs it into fake data or content that resembles the real data or content. The encoder and the decoder are trained to minimize the reconstruction error and the divergence from a prior distribution, resulting in realistic and diverse data or content.
- Generative Pre-trained Transformer 4 (GPT-4): GPT-4 is a type of neural network that uses a transformer architecture, which is a type of neural network that uses attention mechanisms to learn the relationships and dependencies between different parts of the data or content. GPT-4 is pre-trained on a large corpus of text, such as the Common Crawl, and can generate realistic and diverse text for various tasks and domains, such as natural language processing, computer vision, or speech recognition.
How They Can Help You Overcome Real Data Challenges and Enable New Possibilities and Innovations
These generative AI models can generate synthetic data or content that can help you overcome the real data challenges and enable new possibilities and innovations in different domains.
Here are some examples of how generative AI and synthetic data are used in each domain:
- Healthcare: In healthcare, generative AI and synthetic data can help you generate synthetic medical images, records, and reports for diagnosis, treatment, and research. For example, you can use GANs to generate synthetic MRI scans, X-rays, or CT scans that can augment your existing data and improve your image analysis and segmentation models. You can also use GANs to generate synthetic medical records and reports that can preserve the privacy and security of your patients and comply with the regulations, while still providing useful information and insights for your medical decision making and research.
- Finance: In finance, generative AI and synthetic data can help you generate synthetic financial transactions, statements, and reports for fraud detection, risk management, and compliance. For example, you can use VAEs to generate synthetic financial transactions that can mimic the patterns and behaviors of real transactions and help you detect and prevent fraud and money laundering. You can also use VAEs to generate synthetic financial statements and reports that can protect the confidentiality and integrity of your clients and comply with the regulations, while still providing accurate and reliable information and analysis for your financial decision making and reporting.
