Why is preparing the dataset properly important for efficient training of machine learning models?

Saturday, 05 August 2023 by EITCA Academy

Preparing the dataset properly is of utmost importance for efficient training of machine learning models. A well-prepared dataset ensures that the models can learn effectively and make accurate predictions. This process involves several key steps, including data collection, data cleaning, data preprocessing, and data augmentation. Firstly, data collection is important as it provides the foundation

What is the role of the TensorFlow `concat` function in converting the 2D arrays into tensors?

Saturday, 05 August 2023 by EITCA Academy

The TensorFlow `concat` function plays a important role in converting 2D arrays into tensors within the context of preparing datasets for machine learning using TensorFlow.js. This function allows for the concatenation of tensors along a specified axis, thereby enabling the transformation of 2D arrays into higher-dimensional tensors. In TensorFlow, a tensor is a multi-dimensional array

How does the test split parameter determine the proportion of data used for testing in the dataset preparation process?

Saturday, 05 August 2023 by EITCA Academy

The test split parameter plays a important role in determining the proportion of data used for testing in the dataset preparation process. In the context of machine learning, it is essential to evaluate the performance of a model on unseen data to ensure its generalization capabilities. By specifying the test split parameter, we can control

What is the purpose of encoding categorical data in the dataset preparation process?

Saturday, 05 August 2023 by EITCA Academy

Encoding categorical data is a important step in the dataset preparation process for machine learning tasks in the field of Artificial Intelligence. Categorical data refers to variables that represent qualitative attributes rather than quantitative measurements. These variables can take on a limited number of distinct values, often referred to as categories or levels. In order

Why is shaping data an important step in the data science process when using TensorFlow?

Saturday, 05 August 2023 by EITCA Academy

Shaping data is an essential step in the data science process when using TensorFlow. This process involves transforming raw data into a format that is suitable for machine learning algorithms. By preparing and shaping the data, we can ensure that it is in a consistent and organized structure, which is important for accurate model training
