What are some possible avenues to explore for improving a model's accuracy in TensorFlow?

Saturday, 05 August 2023 by EITCA Academy

Improving a model's accuracy in TensorFlow can be a complex task that requires careful consideration of various factors. In this answer, we will explore some possible avenues to enhance the accuracy of a model in TensorFlow, focusing on high-level APIs and techniques for building and refining models. 1. Data preprocessing: One of the fundamental steps

Why is it important to use the same processing procedure for both training and test data in model evaluation?

Saturday, 05 August 2023 by EITCA Academy

When evaluating the performance of a machine learning model, it is important to use the same processing procedure for both the training and test data. This consistency ensures that the evaluation accurately reflects the model's generalization ability and provides a reliable measure of its performance. In the field of artificial intelligence, specifically in TensorFlow, this

What is overfitting in machine learning models and how can it be identified?

Saturday, 05 August 2023 by EITCA Academy

Overfitting is a common problem in machine learning models that occurs when a model performs extremely well on the training data but fails to generalize well on unseen data. In other words, the model becomes too specialized in capturing the noise or random fluctuations in the training data, rather than learning the underlying patterns or

How is the accuracy of the trained model evaluated against the test set in TensorFlow?

Saturday, 05 August 2023 by EITCA Academy

To evaluate the accuracy of a trained model against the test set in TensorFlow, several steps need to be followed. This process involves calculating the accuracy metric, which measures the performance of the model in correctly predicting the labels of the test data. In the context of text classification with TensorFlow, designing a neural network,
