I have read inertia weight PSO but not able to understant how it will help me for malware detection? i am not getting how it can apply to rank features ?
i am confuse that PSO is used to rank features or it is used with classification technique to improve its accuracy. i mean PSO can be used instead of IG(information gain) or it is used with SVM to enhace its classification accuracy.
Hi Suman!
Since PSO can work dynamically and an intelligent approach to find the parameters which gives maximum optimized value so it can be used for malware detection. all the particles in the PSO algorithm are always trying to fnd to the best known position
and also being guided by the best known local particle’s
position. Whenever the best position is gained by a particle,
then the local best known position is updated. So if we can train the system defining the malware with a specific value or solution then PSO can automatically detect the malware comparing new solution with the given one.

All the best.
For adapting PSO in any solving problem, you should address the following issues:
1- solution encoding: you have to define the solution Space clearly, by descrbing the feature of each solution, binary encoding, integer encoding and so on.
2- Fitness compting: here you have to define function, to evaluate the solutions. and you have to mention if the aim is to maximize this function or minimize it.
3- Update position: here you have to define function that updates positions of the particles, according to the previous position and the velocity.
