Questions and answers designated by tag: Memory Management

Why does the batch size in deep learning need to be set statically in TensorFlow?

Friday, 09 August 2024 by Tomasz Ciołak

In the context of deep learning, particularly when utilizing TensorFlow for the development and implementation of convolutional neural networks (CNNs), it is often necessary to set the batch size statically. This requirement arises from several interrelated computational and architectural constraints and considerations that are pivotal for the efficient training and inference of neural networks. 1.

Why a developer would choose to use local scope variables in JavaScript?

Tuesday, 21 May 2024 by Mirek Hermut

When developing applications in JavaScript, developers often need to make decisions about variable scope, which significantly impacts the maintainability, readability, and performance of the code. One critical decision revolves around whether to use local scope variables or global scope variables. A developer might choose to use local scope variables for several compelling reasons, including encapsulation,

What is the purpose of the "Data saver variable" in deep learning models?

Sunday, 13 August 2023 by EITCA Academy

The "Data saver variable" in deep learning models serves a important purpose in optimizing the storage and memory requirements during the training and evaluation phases. This variable is responsible for efficiently managing the storage and retrieval of data, enabling the model to process large datasets without overwhelming the available resources. Deep learning models often deal

Why is it important to resize the images to a consistent size when working with a 3D convolutional neural network for the Kaggle lung cancer detection competition?

Tuesday, 08 August 2023 by EITCA Academy

When working with a 3D convolutional neural network for the Kaggle lung cancer detection competition, it is important to resize the images to a consistent size. This process holds significant importance due to several reasons that directly impact the performance and accuracy of the model. In this comprehensive explanation, we will consider the didactic value

Why is it good practice to free the results from memory after executing an SQL query?

Tuesday, 08 August 2023 by EITCA Academy

It is considered good practice to free the results from memory after executing an SQL query in web development using PHP and MySQL. This practice ensures efficient memory management and improves the overall performance of the application. By freeing the results, you release the resources associated with the query, allowing the system to allocate memory

What is the purpose of the address space in a Linux process?

Saturday, 05 August 2023 by EITCA Academy

The address space in a Linux process serves a important role in the overall functioning and security of the system. It is a fundamental concept in operating systems, including Linux, and understanding its purpose is essential for effective Linux system administration and cybersecurity. In simple terms, the address space refers to the range of memory
