When building a machine learning model, one of the most common questions is whether to opt for long-term or short-term predictions. In other words, should you build a model that forecasts an event tomorrow or a month from now?<\/span><\/p>\n Our article will demystify this critical decision-making process. We\u2019ll walk you through a strategic approach that will simplify the challenge of selecting the <\/span>ideal prediction timeframe<\/span>, which is crucial in determining the<\/span> forecast accuracy in ML models<\/span>.<\/span><\/p>\n As we dive into <\/span>machine learning model forecasting<\/span>, the first question that arises is, \u201c<\/span>How far into the future should my forecasts be directed?\u201d<\/span><\/i> For instance, if you’re predicting demand for certain products, should you forecast demand for the next week, quarter, or year?\u00a0<\/span><\/p>\n The answer is simple: We tend to be better at forecasting short-term events compared to forecasting events that happen too far away in the future. This is because as we stretch our prediction windows, we introduce more uncertainty and unknowns, which translate into <\/span>a lower predictive quality<\/span><\/a>.<\/span><\/p>\n When you’re deciding how far ahead to make predictions with your machine learning model, it\u2019s important to consider the trade-off between actionability and accuracy.\u00a0<\/span><\/p>\n Let\u2019s break it down.\u00a0<\/span><\/p>\n As the prediction window increases, the actionability of the model increases. For example, if you’re forecasting demand a year from now, and your production cycle takes a month, you can do a wide variety of things, from fixing prices with your suppliers to properly sizing your operational team.<\/span><\/p>\n But here\u2019s the catch: this increase in actionability comes at the expense of predictive power, as we are generally bad at predicting long-term events. Plus, to make these long-term predictions, you would need<\/span> a lot of data<\/span><\/i> \u2014for a year’s prediction, you would need data from at least the previous year.<\/span><\/p>\n If you believe your business has a less-than-perfect AI model in a business setting, consider reading this article on <\/span><\/i>Making Money with Mediocre AI Models: A Guide for Business Stakeholders<\/i><\/b><\/a><\/p>\n The <\/span>ideal prediction time frame<\/span> is the one with <\/span>the shortest prediction window where you still have high actionability<\/span><\/i>.\u00a0<\/span><\/p>\n Start by asking yourself: What’s the shortest period within which the predictions can still significantly impact your business decisions? For example, a month-long forecast is your ideal window if your production process takes a month. It gives you enough time to adjust based on the prediction, without venturing too far into the uncertain future.\u00a0<\/span><\/p>\n This concept of <\/span>long-term vs. short-term predictions<\/span> is not exclusive to time but also applies to how direct or indirect the action you are predicting is. For instance, if you’re building a recommendation system in an e-commerce website, your predictions might include immediate actions like a user clicking a product or adding it to their cart.\u00a0<\/span><\/p>\n In summary, the trade-off between actionability and predictive power is crucial when deciding between <\/span>long-term and short-term predictions in machine learning predictions<\/span>.\u00a0<\/span><\/p>\n Our advice? Always choose the shortest prediction window that allows you to take meaningful action. This approach will help you make the most of your machine-learning model and contribute to informed decision-making and a positive <\/span>business impact of ML forecasts<\/span>.<\/span><\/p>\n Download our eBook and discover the most common pitfalls when implementing AI projects and how to prevent them.<\/p>\n Send me the eBook<\/a>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n<\/section>\n\n How Far Should You Go in Generating Predictions?<\/span><\/h2>\n
