Questions and answers designated by tag: Model Performance

What are the three potential assumptions that could be violated when there is a problem with a model's performance for a business, according to the ML Insights Triangle?

Sunday, 06 August 2023 by EITCA Academy

The ML Insights Triangle is a framework that helps identify potential assumptions that could be violated when there is a problem with a model's performance for a business. This framework, in the field of Artificial Intelligence, specifically in the context of TensorFlow Fundamentals and TensorFlow Extended (TFX), focuses on the intersection of model understanding and

Why is data normalization important in regression problems and how does it improve model performance?

Saturday, 05 August 2023 by EITCA Academy

Data normalization is a important step in regression problems, as it plays a significant role in improving model performance. In this context, normalization refers to the process of scaling the input features to a consistent range. By doing so, we ensure that all the features have similar scales, which prevents certain features from dominating the

How does underfitting differ from overfitting in terms of model performance?

Saturday, 05 August 2023 by EITCA Academy

Underfitting and overfitting are two common problems in machine learning models that can significantly impact their performance. In terms of model performance, underfitting occurs when a model is too simple to capture the underlying patterns in the data, resulting in poor predictive accuracy. On the other hand, overfitting happens when a model becomes too complex
