SRMIST MOZOHACK 19

Nirbhaya App - Push 01

Tasks Covered: Data Pre-processing

• imported COBRA crime datasets ranging from 2008-2019.

• removed redundant features/columns

• removed null/missing entries

• removed outlier values with low frequencies

• split 24 hours into 12 slots (12:00 AM - 2:00 AM, 2:00 AM - 4:00 AM, and so on...)

• labelled each record with a day of year (1-365)

• suitably labelled each record for the above changes

Next Task : create hierarchy of time block, day, neighbourhood respectively, with count attribute. : pass to a k-means classifier to get 3 distinct labelled categories of crime. : will use categories obtained to gauge whether an area is dangerous or not.

Nirbhaya App - Push 02

• created hierarchical structure to label according to crime level

• removed lower lying values from dataset to reduce complexity of said structure

Next Task: -implementing k-means to label crime levels according to general trends. -use these labels to gauge whether an area is dangerous or not
