1. Introduction

Welcome to the documentation for the Zeta library. This comprehensive guide provides detailed information about the Zeta library and its components, focusing on the TimeUpSample2x class. Before we delve into the details, it's important to understand the purpose and significance of this library.

1.1 Purpose

The Zeta library is designed to simplify the development of deep learning models by offering modular components and utilities. One of these components is the TimeUpSample2x class, which plays a crucial role in upscaling the time dimension of tensors.

1.2 Key Features

  • Time Dimension Upsampling: The TimeUpSample2x class allows you to efficiently increase the temporal resolution of your data, which is particularly valuable in various sequential data tasks.

  • Seamless Integration: Zeta modules seamlessly integrate with popular deep learning frameworks like PyTorch, making it easy to incorporate them into your projects.

2. Overview

The Zeta library is built with the aim of providing essential building blocks for deep learning model development. One such block is the TimeUpSample2x class.

2.1 TimeUpSample2x Class

The TimeUpSample2x class is a module designed for upscaling the time dimension of 3D tensors. It is useful in scenarios where increasing the temporal resolution of the data is required.

In the following sections, we will explore the TimeUpSample2x class's definition, initialization parameters, functionality, and usage.

3. TimeUpSample2x Class

The TimeUpSample2x class is at the core of Zeta, providing the ability to increase the temporal resolution of tensors.

3.1 Initialization Parameters

Here are the initialization parameters for the TimeUpSample2x class:

  • dim (int): The number of input channels in the tensor.

  • dim_out (int, optional): The number of output channels in the tensor after upsampling. If not specified, it defaults to the same as dim.

3.2 Methods

The primary method of the TimeUpSample2x class is the forward method, which performs the time dimension upsampling operation on input tensors.

4. Functionality and Usage

Let's explore the functionality and usage of the TimeUpSample2x class.

4.1 Forward Method

The forward method of the TimeUpSample2x class takes an input tensor and applies time dimension upsampling using a convolution operation. Here is the parameter:

  • x (Tensor): The input tensor of shape (batch, channels, time, height, width).

The method returns an upsampled tensor of shape (batch, output_channels, time, height, width).

4.2 Usage Examples

Example 1: Creating a TimeUpSample2x Module

In this example, we create an instance of the TimeUpSample2x class with default settings:

upsample = TimeUpSample2x(dim=64)

Example 2: Using TimeUpSample2x for Upsampling

Here, we demonstrate how to use the TimeUpSample2x module for upsampling an input tensor:

upsample = TimeUpSample2x(dim=64)
input_data = torch.randn(1, 64, 32, 32)
output = upsample(input_data)
print(output.shape)

5. Utility Functions

The Zeta library also provides a set of utility functions used within the modules. These utility functions, such as exists, identity, divisible_by, and more, enhance the modularity and flexibility of the library.

6. Additional Information

Here are some additional tips and information for using the Zeta library and the TimeUpSample2x class effectively:

  • Experiment with different values for the dim and dim_out parameters to control the number of channels in the output tensor.

  • Ensure that the input tensor (x) has the appropriate shape (batch, channels, time, height, width).
