// MODEL OPTIMIZATION AND PROMPT SYNTAX TERM
Stride
In convolutional neural networks, stride refers to the number of steps a filter moves across the input image or data at each step.
TECHNICAL DEFINITION
Stride is a hyperparameter in convolutional layers that dictates the step size with which the convolution filter or kernel slides across the input feature map, influencing the spatial dimensions of the output.
BACKGROUND
Generative artificial intelligence (GenAI) is a subfield of artificial intelligence (AI) that uses generative models to generate text, images, videos, audio, software code or other forms of data. These models learn the underlying patterns and structures of their training data, and use them to generate new data in response to input, which often takes the form of natural language prompts.

USAGE NOTE
A larger stride reduces the output size and computational cost but might lose fine-grained information.
DEVELOPERS
Organizations developing technology related to Stride.
NVIDIA develops GPUs and the CUDA/cuDNN software libraries, which are fundamental for accelerating deep learning computations. Their hardware and software are highly optimized for convolutional operations, where stride is a critical parameter that dictates how a filter moves across input data, directly impacting model performance and efficiency.
As the developer of the TensorFlow framework and Tensor Processing Units (TPUs), Google provides the core tools for AI engineers. Within TensorFlow, stride is a key argument in defining convolutional layers (e.g., tf.nn.conv2d), allowing engineers to control the dimensionality of feature maps in neural networks.
Meta AI is the creator of PyTorch, a leading open-source machine learning library. PyTorch gives engineers direct control over neural network components, including the stride of convolutions in layers like Conv2d. This parameter is essential for designing architectures for computer vision and other domains.
Microsoft has pioneered foundational AI architectures like Residual Networks (ResNet). In these models, strided convolutions are used strategically to downsample feature maps throughout the network, a critical technique in modern AI engineering for building deep and efficient models.
Apple develops the Core ML framework and the Neural Engine hardware for on-device machine learning. AI engineers creating models for Apple devices must carefully configure network parameters, including convolution strides, to ensure optimal performance and efficiency on iPhones and other products.
Qualcomm designs Snapdragon chips with dedicated AI Engines. Their development tools, such as the Qualcomm Neural Processing SDK, allow engineers to optimize deep learning models for mobile devices, which involves fine-tuning low-level parameters like stride for efficient on-device inference.
Intel develops CPUs, GPUs, and specialized AI accelerators, along with the OpenVINO toolkit for model optimization. OpenVINO helps engineers optimize neural network performance by efficiently managing operations like strided convolutions on Intel hardware.
