BKD for Taget Identification
INQUIRYAs an another machine-learning approach, Binary Kernel Discrimination (BKD) is a powerful tool to identify the potential active compounds. It uses a training set of compounds whose structural and qualitative activity data are available to generate a model that can be further applied to rank other compounds based on their possible activity. In BKD, the kernel function is used to computationally calculate the similarity between a test set molecule and the members of the training set.

Structural representation
In the first section, the molecule is represented as 2D fragment bit-string.
Similarity searching
We perform similarity searching using different coefficients.
Weighting schemes
We have different weighting schemes for lead compounds.
Our Capabilities
- Our BKD services are applicable to a very large file of 2D fingerprints as well as different pharmaceutical database.
- We can analyze the dis-similarities between a single test set compound and the training set compounds using the ranking results.
- Our teams deliver a final score which predicts the likelihood of that test set compound being active, assisting in selecting and identifying optimal active compounds.
Our Advantages
- We draw a reliable prediction conclusion from the BKD method which enables to provide data support to our downstream services including similarity searching and structural analysis.
- At BOC Sciences, we have rich experience in the operation of binary kernel discrimination and we can customize the virtual screening strategy according to your specific demand.
