Overfitting machine learning.
Overfitting occurs when a machine learning model matches the training data too closely, losing its ability to classify and predict new data. An overfit model finds many patterns, even if they are disconnected or irrelevant. The model continues to look for those patterns when new data is applied, however unrelated to the dataset.

Overfitting When we run our training algorithm on the data set, we allow the overall cost (i.e. distance from each point to the line) to become smaller with more iterations. Abstract. We conduct the first large meta-analysis of overfitting due to test set reuse in the machine learning community. Our analysis is based on over one hundred machine learning competitions hosted on the Kaggle platform over the course of several years.
