What Does Machine Learning Model Accuracy Mean?
Machine learning model accuracy is one way to evaluate classification models. Essentially it is a metric that, based on the training data, uncovers which model best identifies relationships and patterns between variables within a dataset.
In other words, accuracy is the percentage of predictions each model got right – the number of accurate predictions divided by the total number of predictions.
Although model evaluation does not consider accuracy alone, it is the prime metric when comparing data models.
Due to the significant number of mathematical techniques involved in modeling and the uncertain nature of data, it is also essential to consider how the model will perform on a different dataset and how much flexibility it offers.
Why Is Model Accuracy Very Important?
Models that are accurate and effective at generalizing unseen data are better at forecasting future events and therefore provide more value to your business.
You look to machine learning models to help make practical business decisions. When you use models that produce more accurate outcomes, you get better information and can, therefore, make better decisions.
The cost of wrong information can be high, so mitigating that risk by optimizing model accuracy is essential.
Naturally, identifying the point where returns begin to diminish is also crucial so that you don’t spend excess time and money developing models that won’t move the needle very much.
Model Accuracy and LogicPlum
