The famous quote "The limits of my language mean the limits of my world" by philosopher Ludwig Wittgenstein points to an important insight - that the concepts and categories encoded in language shape and constrain how we understand reality. This idea has profound implications in artificial intelligence as well. AI systems rely on training data to learn about the world. This data provides the raw material for the AI to form its internal representations and capabilities.
However, if the training data has inherent biases or fails to capture the full diversity and complexity of the real world, then the AI's understanding will be limited and skewed right from the start. Its internal "worldview" will be restricted by the incomplete language used to describe the training examples. For example, facial recognition algorithms trained mostly on images of white men often struggle to accurately identify women and people of color. The lack of representative training data limits what the AI can perceive and understand. Even with advanced deep learning techniques, the system cannot grasp concepts it has no language or examples for. Another example is conversational AI like chatbots. These systems are trained on human language data like movie dialogs or customer service logs. But if those conversations lack diversity or depth, the chatbot's ability to understand and respond appropriately will hit limits very quickly. Casual users may not notice, but the chatbot will fail on complex questions or nuanced topics its training language did not encompass.
Practical Ways to Expand AI's Language
Given the power of language to shape AI capabilities, what practical steps can AI developers take to create more expansive and inclusive training data? Here are some promising approaches.
Prioritize diversity - Training data should include diverse voices and perspectives, considering factors like gender, age, cultural background, language, socioeconomic status, and more. AI needs broad exposure to understand real-world complexity.
Crowdsource wisely - Leveraging crowdsourcing to generate training data can expand language diversity. But it's critical to minimize biases by careful prompt designing and balanced crowd selection.
Co-create with users - Companies can collaborate with their end-users to co-create descriptive, real-world training data that captures nuanced domain knowledge and use cases.
Test comprehensively - After training an AI model, companies should rigorously test it on diverse, challenging cases that stress its linguistic limits. This reveals blindspots needing improvement.
By proactively strengthening the language used to develop AI, we inject more of the real world's richness into its knowledge foundations. This fosters AI that is more context-aware, flexible, and ethically-grounded. Of course, the goal is not perfectly comprehensive training data - that is unrealistic. Rather, the goal should be continuously expanding the AI's language to see around its inherent limits as much as possible. Like any tool, AI will always have limits. But with care and effort, we can create AI technologies whose capabilities align closely with the full scope of human needs. Going forward, AI researchers must proactively address representation gaps in training data and find ways to expand the language used to develop AI. It is not enough to feed the AI vast amounts of data - we must ensure that data adequately captures the richness of the real world. Only then can we create AI with less limited horizons.
For investors evaluating AI companies, examining their training data and approaches to mitigate language limitations should be a priority. Firms that take holistic and ethical approaches to training data will build AI that can flexibly understand diverse perspectives and situations. This will enable more trusted and capable AI technologies that benefit businesses and society. Though AI continues advancing rapidly, its capabilities are still fundamentally constrained by the language used to build it. Investors would do well to remember Wittgenstein's lesson.
