Artificial intelligence (AI) continues to revolutionize how businesses operate. But misconceptions about AI can mean lost opportunities.
Two popular types of AI include generative AI and predictive AI. Learn the difference between predictive AI vs. generative AI, including the use cases, benefits, and drawbacks of these two powerful tools.
Predictive AI defined
Predictive AI identifies patterns in data sets using machine learning and statistical analysis. Based on its analysis of historical data, predictive AI models then predict future outcomes. Businesses can train predictive AI models to achieve specific goals.
Benefits
- Forecasting: Industries that rely on forecasting benefit from the analytical power of predictive AI to forecast demand, sales, or trends. In particular, finance, marketing, and e-commerce organizations leverage this benefit.
- Personalization: Drawing on a large data set, predictive AI can generate customer profiles that allow companies to personalize their customer interactions. This has broad applications from retail to healthcare.
- Risk Management: Predictive AI can identify potential threats early, allowing businesses to mitigate their risk. In cybersecurity, predictive AI can anticipate threats, while manufacturing can use predictive AI to optimize machine maintenance and replacement.
Disadvantages
- Uncertainty: While predictive AI can make predictions about the future based on past data, it can fall short when conditions change rapidly. This analytical tool may also struggle with the unpredictability of human behavior.
- Data Quality: The predictive power of AI depends on the quality of the data. Predictive AI models can have data that overrelies on certain sources, is inaccurate, or is biased. Successful models also require large data sets and regular updates to make reliable predictions.
- Data Privacy: Predictive AI models that use personally identifiable information must maintain strong security practices to keep information private. Using individual healthcare or financial information may also raise ethical concerns with AI.
Use cases
Financial forecasts
Analyzing economic trends with predictive AI allows financial institutions to forecast future conditions.
Healthcare treatment plans
Healthcare organizations can analyze patient records to create health profiles and individualized treatment plans.
Inventory management
Based on past sales trends, companies can use predictive AI to manage inventories.
Fraud detection
Predictive AI can evaluate financial transactions to flag possible fraud.
Generative AI defined
Generative AI generates content in response to user prompts. Many use large language models (LLMs) that contain extensive raw data to create new content. Unlike predictive AI, generative AI interacts directly with users in a conversational style.
Benefits
- Productivity: Generative AI can help professionals boost their productivity. It can also summarize material and answer customer questions, freeing up workers' time.
- Personalization: Like predictive AI, generative AI can personalize content. However, generative AI responds to user input and requests. Users can ask a model to use a particular writing style, for example.
- Simulation: Generative AI can create synthetic data in industries such as healthcare and tech, allowing experts to train and test new technologies without using individual data that may raise privacy concerns.
Disadvantages
- Reliability: While generative AI may appear to create reliable content, every model hallucinates. Users may not be able to identify inaccuracies in AI-generated content, creating challenges for businesses. If the data sets contain biased or inaccurate information, it also impacts the reliability of the output.
- Ethics: Generative AI relies on LLMs that often include copyrighted material. Training models on existing content without permission raises ethical questions and accusations of
- Data Security: As with predictive AI, generative AI models may use LLMs that contain sensitive or private information. This raises data privacy issues and requires strong data security practices.
Use cases
Customer service
Generative AI chatbots can respond to customer questions in real-time.
Content creation
Generative AI allows users to create text, images, code, and more. It can also switch between those mediums and turn text into images or images into code.
Document processing
Generative AI can evaluate and summarize documents, extracting information and answering user questions about them.
Translation
Generative AI models can translate documents into different languages.
Predictive AI vs generative AI: How to choose
How can you choose an AI solution for your business or workflow? The process starts with identifying your business objectives. While generative AI focuses on personalization and optimization of your work and customer flows, predictive AI emphasizes analytical forecasting. Knowing your goals — and what you want AI to achieve — will help you make an informed decision.
Questions to ask when choosing generative AI vs. predictive AI:
- Does predictive AI or generative AI align with your needs?
- Do you have the AI skills to implement these tools?
- What data do you have to customize an AI model?
- How will you follow data protection regulations?
Many professionals can benefit from learning more about AI, as well as machine learning and automation.
Consider educational resources to expand your AI knowledge. For example, you can consider an AI Executive Education program or a master's in artificial intelligence on edX.
Upskilling can help you transition into AI as a senior leader or better leverage AI in your current role.
