Pfupiso
It matters because pure relevance ranking often returns near-duplicate passages that waste space in a RAG context window.
Kudzika Kwakadzika
Kana hurongwa hwekutsvaga huchiwana magwaro chete nekukoshera kumubvunzo, mibairo yepamusoro inowanzo shaya basa - ndima shanu dzese dzichitaura chinhu chimwe. MMR, yakaunzwa naCarbonell naGoldstein muna 1998, inogadzirisa izvi nekusarudza mhinduro imwe panguva. Panhanho imwe neimwe inotora mumiriri anokwirisa musanganiswa wakayerwa: lambda inopeta kukosha kwayo kumubvunzo, kubvisa (1 minus lambda) nguva dzayakafanana zvakanyanya kune chero chatosarudzwa kare. Lambda iri pedyo ne1 inofarira kukosha kwakachena; pedyo ne0 inofarira kusiyana-siyana. Muchizvarwa chekutsvaga-chakawedzerwa, MMR inofarirwa nekutora zvakasiyana-siyana zvezvimedu kuitira kuti modhi yemutauro ione humbowo hunopindirana pane kuti chokwadi chimwechete chidzokororwe, kuvandudza kuvharika pasina kuwedzera mamiriro.

What is Maximum Marginal Relevance?
Maximum Marginal Relevance (MMR) inzira yekuisa zvinzvimbo zvakare inoyera kuti mhedzisiro inoenderana nekusiyana kwayakaita kubva kune zvakatosarudzwa. Izvo zvine basa nekuti kwakachena kuenderana chinzvimbo kunowanzo dzorera padhuze-duplicate ndima iyo inoparadza nzvimbo muRAG mamiriro hwindo.
Nderipi dambudziko rekutanga iro MMR rakagadzirirwa kugadzirisa?
MMR inogadzirisa maitiro ekuenderana-chete chinzvimbo kuburitsa mibairo mizhinji inotaura chinhu chimwe chete, nekupa mubairo mutsva.
MuMMR formula, lambda inokosha pedyo ne1 inosimbisa chii?
Lambda huremu kukosha; pedyo ne1 izwi rekukosha rinotonga, nepo pedyo ne0 mutsauko (kuderera-kufanana) izwi rinotonga.
