What is Overfitting deep learning?

Overfitting refers to a model that models the “training data” too well. Overfitting happens when a model learns the detail and noise in the training data to the extent that it negatively impacts the performance of the model on new data .

Can Overfitting be good?

Typically the ramification of overfitting is poor performance on unseen data. If you’re confident that overfitting on your dataset will not cause problems for situations not described by the dataset, or the dataset contains every possible scenario then overfitting may be good for the performance of the NN.

How do you handle a small data set?

In this kernel we will see some techniques to handle very small datasets, where the main challenge is to avoid overfitting….Why small datasets lead to overfitting? Use simple models. Beware the outliers. Select the features. Balance the dataset with synthetic samples (SMOTE) Combine models for the final submission.

Why does more data increase accuracy?

Having more data is always a good idea. It allows the “data to tell for itself,” instead of relying on assumptions and weak correlations. Presence of more data results in better and accurate models. For example: we do not get a choice to increase the size of training data in data science competitions.

What model would have the lowest training error?

A model that is underfit will have high training and high testing error while an overfit model will have extremely low training error but a high testing error.
