Save and Load Model

Watch the video to learn more.

In this video, Professor Khanh discusses the importance of saving and loading machine learning models using Weka because training a model can take a significant amount of time, especially for deep learning models, sometimes spanning hours, days, or even weeks. Therefore, saving and loading models becomes essential to avoid the need for retraining and to reduce time and computational resources.

Professor Khanh demonstrates the step-by-step process of saving and loading models using Weka. He starts by explaining the concept of finalizing the model and then proceeds to show how to save it to a file. Next, he will demonstrate the instructions on how to load the model from the file and use it for making predictions on new data. The video also covers training a machine learning model using Weka, including techniques like cross-validation.

Additionally, he highlights the options for evaluating and modifying the output of the results in Weka, such as selecting specific information, saving the output to a file, and re-evaluating models on current tests. Professor Khanh emphasizes the importance of understanding prediction accuracy, reproducibility, and the routes of the results.
