English: This image represents the problem of overfitting in machine learning. The red dots represent training set data. The red dots represent training set data. The green line represents the true functional relationship, while the red line shows the learned function, which has fallen victim to overfitting.
Underfitting is the inverse of overfitting, meaning that the statistical model or machine learning algorithm is too simplistic to accurately capture the patterns in the data. A sign of underfitting is that there is a high bias and low variance detected in the current model or algorithm used (the inverse of overfitting: low bias and high variance).
Machine learning (ML) is a field of study in artificial intelligence concerned with the development and study of statistical algorithms that can learn from data and generalize to unseen data, and thus perform tasks without explicit instructions. [1]
A training data set is a data set of examples used during the learning process and is used to fit the parameters (e.g., weights) of, for example, a classifier. [9] [10]For classification tasks, a supervised learning algorithm looks at the training data set to determine, or learn, the optimal combinations of variables that will generate a good predictive model. [11]
Another issue is reliability or bias. While attorneys swear an oath to set aside their personal prejudices, biases, and beliefs to faithfully uphold the law and represent their clients, generative artificial intelligence is the product of programming devised by humans who did not have to swear such an oath.
[1] [2] Random forests correct for decision trees' habit of overfitting to their training set. [ 3 ] : 587–588 The first algorithm for random decision forests was created in 1995 by Tin Kam Ho [ 1 ] using the random subspace method , [ 2 ] which, in Ho's formulation, is a way to implement the "stochastic discrimination" approach to ...

Techniques like early stopping, L1 and L2 regularization, and dropout are designed to prevent overfitting and underfitting, thereby enhancing the model's ability to adapt to and perform well with new data, thus improving model generalization.
