Does a proper approach to neural networks require a training dataset and an out-of-sample testing dataset, which have to be fully separated?
In the realm of deep learning, particularly when employing neural networks, the proper handling of datasets is of paramount importance. The question at hand pertains to whether a proper approach necessitates both a training dataset and an out-of-sample testing dataset, and whether these datasets need to be fully separated. A fundamental principle in machine learning
Why too long neural network training leads to overfitting and what are the countermeasures that can be taken?
Training Neural Network (NN), and specifically also a Convolutional Neural Network (CNN) for an extended period of time will indeed lead to a phenomenon known as overfitting. Overfitting occurs when a model learns not only the underlying patterns in the training data but also the noise and outliers. This results in a model that performs
How can we prevent unintentional cheating during training in deep learning models?
Preventing unintentional cheating during training in deep learning models is important to ensure the integrity and accuracy of the model's performance. Unintentional cheating can occur when the model inadvertently learns to exploit biases or artifacts in the training data, leading to misleading results. To address this issue, several strategies can be employed to mitigate the
How can you evaluate the performance of a trained deep learning model?
To evaluate the performance of a trained deep learning model, several metrics and techniques can be employed. These evaluation methods allow researchers and practitioners to assess the effectiveness and accuracy of their models, providing valuable insights into their performance and potential areas for improvement. In this answer, we will explore various evaluation techniques commonly used

How do we test if the SVM fits the data correctly in SVM optimization?
To test if a Support Vector Machine (SVM) fits the data correctly in SVM optimization, several evaluation techniques can be employed. These techniques aim to assess the performance and generalization ability of the SVM model, ensuring that it is effectively learning from the training data and making accurate predictions on unseen instances. In this answer,
What is overfitting in machine learning and why does it occur?
Overfitting is a common problem in machine learning where a model performs extremely well on the training data but fails to generalize to new, unseen data. It occurs when the model becomes too complex and starts to memorize the noise and outliers in the training data, instead of learning the underlying patterns and relationships. In

What is overfitting in machine learning models and how can it be identified?
Overfitting is a common problem in machine learning models that occurs when a model performs extremely well on the training data but fails to generalize well on unseen data. In other words, the model becomes too specialized in capturing the noise or random fluctuations in the training data, rather than learning the underlying patterns or

How can overfitting be mitigated during the training process of an image classifier?
Overfitting is a common problem that occurs during the training process of an image classifier in the field of Artificial Intelligence. It happens when a model learns the training data too well, to the point that it becomes overly specialized and fails to generalize to new, unseen data. This can lead to poor performance and
