how to test a model in test data set weka

Sample Weka Data Sets Fordham
Suppose a time series forecasting model is trained with a set of data and gives a good evaluation with test-set in time_range-1 and model produces a function F1. For time_range-2 and another set of training and testing data model generates function F2. Similarly for time_range-N the model generate Function FN. How the different models when combined and implemented forecast the result based on... Data Mining Resources. Academic Lineage. Student Animations . Dr. Weiss in the News. Inside Fordham Nov 2014.

machine learning Train and test set are not compatible

For almost any machine learning algorithm, the training data and the test data need to have the same format. That means, both must have the same features, i.e. attributes in weka, in the same format, including the class....
WEKA reports most of these measures quite clearly (in the summary output), and you can use a ThresholdCurve to plot ROC curves. Once you've decided that, confidence intervals and the paired t-test are commonly used.

2012-04-23 · Weka machine learning tool has the option to develop a classifier and apply that to your test sets. This tutorial shows you how. Weka machine learning tool has the option to develop a classifier

  • You need to project the test set into this space (defined by the principal components of your training data) to calculate predictions in your model. I don't have weka handy so I can't poke around the specific PCA implementation there, but the basic idea is that you need project the test data into the same space you projected your training data into.
  • 1. Finalize a Machine Learning Model. Perhaps the most neglected task in a machine learning project is how to finalize your model. Once you have gone through all of the effort to prepare your data, compare algorithms and tune them on your problem, you actually need to create the final model that you intend to use to make new predictions.
  • K-means clustering is a type of unsupervised learning but when I use it in weka I can give a test set it. if it is unsupervised what is the meaning of a test set? if I provide a test set and run the algorithm and then get 2 clusters one with 80% and other with 20% is it equal to correctly classified instances in classification algorithms?
  • A model that is selected for its accuracy on the training dataset rather than its accuracy on an unseen test dataset is very likely have lower accuracy on an unseen test dataset. The reason is that the model is not as generalized. It has specalized to the structure in the training dataset. This is called
