  1. overfitting - What should I do when my neural network doesn't ...

    Overfitting for neural networks isn't just about the model over-memorizing, its also about the models inability to learn new things or deal with anomalies. Detecting Overfitting in Black Box Model: …

  2. machine learning - Overfitting and Underfitting - Cross Validated

    Mar 2, 2019 · 0 Overfitting and underfitting are basically inadequate explanations of the data by an hypothesized model and can be seen as the model overexplaining or underexplaining the data. This …

  3. definition - What exactly is overfitting? - Cross Validated

    So, overfitting in my world is treating random deviations as systematic. Overfitting model is worse than non overfitting model ceteris baribus. However, you can certainly construct an example when the …

  4. How does cross-validation overcome the overfitting problem?

    Jul 19, 2020 · Why does a cross-validation procedure overcome the problem of overfitting a model?

  5. how to avoid overfitting in XGBoost model - Cross Validated

    Jan 4, 2020 · Firstly, I have divided the data into train and test data for cross-validation. After cross validation I have built a XGBoost model using below parameters: n_estimators = 100 max_depth=4 …

  6. What's a real-world example of "overfitting"? - Cross Validated

    Dec 11, 2014 · I kind of understand what "overfitting" means, but I need help as to how to come up with a real-world example that applies to overfitting.

  7. SVM, Overfitting, curse of dimensionality - Cross Validated

    Aug 29, 2012 · Overfitting from an algorithm which has inferred too much from the available training samples. This is best guarded against empirically by using a measure of the generalisation ability of …

  8. overfitting - Is it possible to have a higher train error than a test ...

    Jul 20, 2022 · These simplified formulae from Stanley Сhan's Introduction to Probability for Data Science provide some good intuition on the train/test error: MSE train = σ (1 - d/N) MSE test = σ (1 + d/N) …

  9. Random Forest - How to handle overfitting - Cross Validated

    Aug 15, 2014 · Empirically, I have not found it difficult at all to overfit random forest, guided random forest, regularized random forest, or guided regularized random forest. They regularly perform very …

  10. r - Overfitting using lightGBM? - Cross Validated

    Feb 8, 2023 · Yes, we are likely overfitting because we get "45%+ more error" moving from the training to the validation set. That said, overfitting is properly assessed by using a training, validation and a …
