Dealing With Imbalanced Datasets

Summary:  Dealing with imbalanced datasets is an everyday problem.  SMOTE, Synthetic Minority Oversampling TEchnique and its variants are techniques for solving this problem through oversampling that have recently become a very popular way to improve model performance.

 

There are some problems that never go away. …

A Guide for Applying Machine Learning Techniques in Finance

Does it sound familiar to you? In order to get an idea of how to choose a parameter for a given classifier, you have to cross reference to a number of papers or books, which often turn out to present competing arguments for or against a certain parameterization choice but with few applications to real-world problems.

For example, you may find a few papers discussing optimal selection of K in…

Parameter Selection in Classification for Financial Market

In practice, we often have to make parameterization choices for a given classifier in order to achieve optimal classification performances; just to name a few examples:

  • Neural Network: e.g., the optimal choice of Activation Functions, # of hidden units
  • Support Vector Machine: e.g., the optimal choice of Kernel Functions
  • Ensemble: e.g., the number of Learning Cycles for Bagging.
  • Discriminant Analysis: e.g., Linear/Quadratic; regularization…

Apply Machine Learning Techniques to Problems in Financial Market

Past literature show that the comparisons of classifier's performance are specific to the types of datasets (e.g., Pharmaceutical industry data) used; i.e., some classifiers may perform better in some context than others. A paper titled CDS Rate Construction Methods by Machine Learning Techniques conducts the performance comparison exclusively in the context of financial market by applying a wide range of classifiers to provide solution to so-called Shortage of…

SVM in Practice

Many Machine Learning articles and papers describe the wonders of the Support Vector Machine (SVM) algorithm. Nevertheless, when using it on real data trying to obtain a high accuracy classification, I stumbled upon several issues.

I will try to describe the steps I took to make the algorithm work in practice.



This model was implemented…
