- #Vlozte do pole
- # new_persons_results = []
- # data o nekolika malo novych pacientech bez ukoncovaci 0 a 1, ale se stejnym poctem sloupcu jako ma soubor z Vaseho lokalniho disku, vyse by tedy toto bylo rovno 2
- #kod vyhodi hned po natrenovani, (jehoz prubeh muzete sledovat na modre progres bare) pro kazdy radek z new_persons_results bilo-sedo-cerne ctverecky vznikle z normalizace poskytnutych dat a ukoncovaci ctverecek cerveny pripadne zeleny
- #zaroven s tim se vypise realne cislo mezi 0 a 1 znacici jak moc je pacient zdravy (blizke 0) ci nemocny (blizke 1)
- #cisla uprostred pak indikuji zadany oranzovy semafor.
- #je na lekarich nastavit tresholdy (tedy pravdepodobnosti: cisla mezi 0 a 1) ktere pak daji zaver, zda je pacient cerveny, oranzovy ci zeleny
- # prosim o komnetare a vysledky na realnych datech, je zadouci aby radku v matici, tedy pacientu byly stovky a sloupcu desitky
- # Moznosti vyuziti: onkologicka diagnoza vs. zdrava kontorlni skupina, diabetes (pritomnost/nepritomnost), testovani noveho leku oproti placebu atd.
- #kod zaroven vyhodi confusion matici, tedy mozne True Negative a False Positive plus spravne zarazene hodnoty spolu s presnosti,F1 score recall atd.
- #poznamka ke kodu: jde o epxerimentalni verzi, ktera krome skutecne potrebneho kodu obsahuje ladici informace, ruzne duplicity, nadbytecne prikazy atd.
- # Na uvod behu programu se pro kontorlu vypise poskytnuta matice a jeji normalizovana verze, je treba sjet jezdcem napravo nize na obrazky a dalsi vystupy
- #Dekuji profesoru Petru Dostalovi za namet k teto praci a poskytnuta data, byt je potreba mit data realna
