dm-ml's Issues

Create the data processor

quel robo che dato
flow_features base_features content_features time_features
rende
genereated_features

Feature selection

  • a un certo punto dobbiamo fare i benchmark sull'applicazione vera

time := tempo per vedere se una richiesta è malevola o no

From nominal to float in a good way

when using random forest and similiars, for now you're using

for n in nominals_features:
	tmp, indexes = pd.factorize(data[n])
	data[n] = tmp

Data Preprocessing

  • Pulizia rumore (e outlier) -> fare un boxplot / maybe clustering?
  • Feature reduction -> PCA / Feature selection based on mutual information
  • Data reduction (se serve) -> Sampling / Data aggregation / compression?
  • Normalization -> min-max (attenti agli outlier) / z-score
  • Discretization -> binning / histogram / clustering / decision-tree / chi2 analysis

Check NaN columns

  • flow_features (un po' tutte kekkate)
  • ['ct_flw_http_mthd','is_ftp_login','ct_ftp_cmd'] sono kekkate nel 2,3,4 dataset
