Questions and answers designated by tag: Hyperparameter Tuning

What are some examples of hyperparameter tuning?

Saturday, 13 January 2024 by Pravendra Singh

Hyperparameter tuning is a important step in the process of building and optimizing machine learning models. It involves adjusting the parameters that are not learned by the model itself, but rather set by the user prior to training. These parameters significantly impact the performance and behavior of the model, and finding the optimal values for

Why too long neural network training leads to overfitting and what are the countermeasures that can be taken?

Tuesday, 22 August 2023 by EITCA Academy

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

What is the recommended batch size for training a deep learning model?

Sunday, 13 August 2023 by EITCA Academy

The recommended batch size for training a deep learning model depends on various factors such as the available computational resources, the complexity of the model, and the size of the dataset. In general, the batch size is a hyperparameter that determines the number of samples processed before the model's parameters are updated during the training

Why is it important to split the data into training and validation sets? How much data is typically allocated for validation?

Sunday, 13 August 2023 by EITCA Academy

Splitting the data into training and validation sets is a important step in training convolutional neural networks (CNNs) for deep learning tasks. This process allows us to assess the performance and generalization ability of our model, as well as prevent overfitting. In this field, it is common practice to allocate a certain portion of the

How does the learning rate affect the training process?

Sunday, 13 August 2023 by EITCA Academy

The learning rate is a important hyperparameter in the training process of neural networks. It determines the step size at which the model's parameters are updated during the optimization process. The choice of an appropriate learning rate is essential as it directly impacts the convergence and performance of the model. In this response, we will

Why is the validation loss metric important when evaluating a model's performance?

Sunday, 13 August 2023 by EITCA Academy

The validation loss metric plays a important role in evaluating the performance of a model in the field of deep learning. It provides valuable insights into how well the model is performing on unseen data, helping researchers and practitioners make informed decisions about model selection, hyperparameter tuning, and generalization capabilities. By monitoring the validation loss

What is the role of the regularization parameter (C) in Soft Margin SVM and how does it impact the model's performance?

Monday, 07 August 2023 by EITCA Academy

The regularization parameter, denoted as C, plays a important role in Soft Margin Support Vector Machine (SVM) and significantly impacts the model's performance. In order to understand the role of C, let's first review the concept of Soft Margin SVM and its objective. Soft Margin SVM is an extension of the original Hard Margin SVM,
