Kielelezo cha Nje cha Mtaa (LOF)
Kielelezo cha Nje cha Mtaa (LOF) ni algoriti ya ugunduzi wa uhalifu isiyo na usimamizi inayotegemea msongamano, iliyoanzishwa na Breunig, Kriegel, Ng, na Sander mwaka 2000. Inampa kila nukta data alama ya nje inayoendelea ambayo inakadiria jinsi nukta hiyo ilivyo pekee ikilinganishwa na mtaa wake wa karibu, ikiruhusu kugundua uhalifu ambao mbinu za kimataifa hukosa kwa sababu zinachanganyika na makundi yenye msongamano mahali pengine kwenye nafasi.
