Day 9

Today I began by completing the change to my code that I had begun the previous day, allowing me to finally run a trial on the first preprocessing method I was to test, "MinMaxScaler." The metrics looked strange at first, and it turned out that while the mean-class accuracy of the first trial was fairly good, the overall accuracy was too low. I talked to Ron about this issue, and after much searching for an error, we found that there was a problem with shuffling the data. After that was solved, I began to successfully run trials on the preprocessing methods. Today I ran thirty trials on each of five out of the seven preprocessing methods which I am testing. I plan to run trials on the remaining two methods tomorrow. Each group of thirty trials took about thirty minutes, so meanwhile I worked on creating a diagram of the machine learning pipeline and writing a description of what each preprocessing method I am testing does. I will continue these descriptions and perform the remaining trials tomorrow.

Day 6

I began today by finishing the documentation I had been doing of the code for my experiment. After that, I began working on new code that would test the performance of data preprocessing methods that were already written. I am using the Pavia University scene, which is a set of labeled hyperspectral data. I began to write code to run the experiment, which will include testing various preprocessing methods each with thirty trials. In the process, I used the code from my first tutorial as a reference, and I found an error in that code that had been making it run too slowly. It had been using too much data to train. I fixed this issue, making that code run more quickly, and continued with the code for my experiment. Eventually, in my experiment code, I ran into a problem: I was shaping the data into different dimensions to split it into training and testing groups, but it had to be in its original dimensions to be used by the preprocessing methods. I am still working on this issue, and I ...

Day 14

Today I continued testing different parameters for the MLP classifier. While I ran tests, I finished documenting the classifiers that I am testing. I also wrote an introduction to my descriptions of the preprocessing methods, finished citations for the descriptions, and wrote a summary of my preprocessing experiment in an article being written in Overleaf about the machine learning pipeline. Although I am not yet ready to test the next classifier, RandomForest, I began writing code to test for the optimal preprocessing methods and parameters to use with it. Throughout the day, I collected data on the metrics of different combinations of parameters for MLP. I looked through this data and ran a larger number of trials on the most promising parameters, but it still appears that the default parameters are the most accurate, even though the overall accuracy resulting from the default parameters averages at about seventy percent, which is not very good compared to the other two classifiers I...

Day 3

Today I began by implementing the changes in the tutorial that Ron and I had previously discussed. I used arrays in my code instead of multilevel lists, because the machine learning program requires arrays. I then used two different machine learning programs, one linear and one non-linear, to process the training data and predict the second array of testing data based on the first. The linear learning program (a Linear Support Vector Machine) was more successful and now only takes about two minutes to train and make its predictions. I ran metrics to test the accuracy of the linear program, such as overall accuracy, mean-class accuracy, and kappa statistic, and it proved to be fairly accurate. Later in the tutorial, the accuracy will be improved with further measures. However, the non-linear program (a Support Vector Machine with Radial Basis Function kernel) is still too slow and inefficient. I am not certain why this is, but tomorrow I hope to fix this issue.
