Spoiler Alert:<\/strong> This content was meant to be included within the pages of my upcoming Wiley book on data and AI strategies for growth. I decided to cut it from my manuscript and share it directly with Convergence members here, but if you\u2019d like to be notified when the book becomes available, be sure to jot your name down on this list<\/a>.<\/p>\n

Illustrating discriminative vs generative models<\/strong>with examples<\/h1>\n

I\u2019ll start off with a simple example.<\/strong> You know how Gmail quickly separates spam from non-spam emails? What it\u2019s doing is \u201cclassifying\u201d or \u201csegregating\u201d the email data into two buckets. A discriminative model does exactly that. It identifies patterns that differentiate one type of data from another. When you\u2019re training a discriminative model, you\u2019re teaching it to understand or discover patterns that are distinct to each data type. So, a good model here is one that can detect spam mail from a mile away and throw it in the bin.<\/p>\n

When trained well, your generative model can actually create a text that resembles a spam email. Woohoo! \ud83e\udd73<\/strong><\/p>\n<\/blockquote>\n<\/div>\n

Generative models are different. Instead of just identifying the differences between the data types, they\u2019ll actually attempt to \u201cunderstand\u201d the inherent characteristics of spam and non-spam data. This is analogous to profiling. These models could be used to clue in on what goes into creating a spam or a non-spam email and – with each iteration – they\u2019ll get more accurate and more precise. So, when trained well, your generative model can actually create a text that resembles a spam email. Woohoo! \ud83e\udd73<\/strong><\/p>\n

Choosing between discriminative vs generative models\u00a0<\/strong><\/h1>\n

When choosing between these two types of models, you need to closely examine the specific objectives and requirements of the data strategy you\u2019re building. For instance, if the strategy is focused on identifying trends in customer behaviors or segmenting markets, discriminative models might be more appropriate. Conversely, if the strategy involves innovating new products or simulating data for stress testing, then generative models would be more suitable.<\/p>\n

Let\u2019s say you have all your data resources in one place, and you want to build a forecasting or predictive feature atop them. If you wanted to predict whether a customer will churn, or forecast sales for the next quarter, then the discriminative model<\/strong> would be a better choice because it will help you predict, forecast, cluster<\/strong>, or classify<\/strong> based on your requirement.<\/p>\n

If, however, you\u2019re looking to add a new feature but you don\u2019t have the data resources in place support it, then you\u2019ll typically start by gathering data. In this data-gathering phase, you can start off by using a LLM + RAG to generate<\/strong> synthetic data<\/a> that you can use for the pilot phase while you put your data-gathering mechanism or pipeline in place. Here, you\u2019ll be using what we refer to as the generative<\/strong> model. In fact, there are third-party companies that solely work on helping you generate data through simple queries or prompts.<\/p>\n

Tip:<\/strong>\u00a0 \u00a0\u00a0When you\u2019re using LLMs to generate data, be sure to provide detailed prompts to help you generate close to real-world data.<\/p>\n

Action steps for implementing your model choices<\/strong><\/h1>\n

Now that you understand the fundamental differences between discriminative vs generative models and how they fit into differing strategic needs, the next step is to evaluate your current projects and data initiatives. To do that, start by asking yourself:<\/p>\n

    \n
  1. Which projects could benefit from more precise classification or prediction?<\/strong> Consider using discriminative models for these to improve accuracy and efficiency.<\/li>\n
  2. Where might you innovate or create with data?<\/strong> For projects needing innovation or simulation, look into employing generative models to foster creativity and extend your data capabilities.<\/li>\n
  3. Assess your data readiness:<\/strong> Do you have the necessary data to support these models? If not, it might be time to explore synthetic data generation or to bolster your data collection strategies.<\/li>\n
  4. Consult with experts:<\/strong> If you’re unsure about the best approach, consider reaching out to an advanced data science consultant who can provide you with the insights and guidance you need to tailor to your specific circumstances.<\/li>\n<\/ol>\n

    By actively applying these considerations, you can more effectively align your AI strategy with your business objectives to gain a clear competitive edge. Keep in mind, when choosing between discriminative vs generative models, the right model will be able to support your current needs and adapt to future challenges and opportunities.<\/p>\n
