SVM for Lead Discovery
INQUIRYSupport Vector Machine (SVM) has been explored as a ligand-based virtual screening (VS) tool for facilitating lead discovery. The goal of this method is to create a decision boundary that separates two classes of points according to the active and inactive compounds. A key characteristic of SVM is to reduce the error on training data, minimize the complexity of models and avoid the overfitting with the application of the structural risk minimization approach.

- Stable.
- Easy to understand: Simple geometric interpretation.
- Nonlinear decisions based on the use of kernels.
Application in Drug Discovery
- SVM is applied to predict the distinction between active compounds and inactive ones through binary class labeling.
- SVM can also be utilized to rank compounds in database according to their activity potential in virtual screening.
- SVM can assess potency of candidates and theirs druggability.
Our Capabilities
- We have established an advanced SVM platform to optimize the screening process using the maximum margin hyperplanes.
- Our SVM technologies can separate the active from the inactive compounds rapidly and have the largest possible distance from any labeled compound.
- We have experience in choosing right SVM parameters to develop SVM models.
- Our teams apply the cross validation-derived statistic to select one among the different possible models.
Our advantages
- We provide both single and multi-target prediction with high success rate.
- At BOC Sciences, our professional scientists are capable of performing data processing and interpretation.
