Hello guys, I trained my yolov4 detector using 350 images and 50 epochs… but average precision for each object was not as good as I want… what can I do to increase the average precision?

在 MATLAB Online 中打开

i have code like this to remove rows...

% Nahratie tabulky LabelData
load('LabelData.mat');
% Zadanie ciest k obrazkom, ktoré chceš vymazať
pathsToDelete = {'E:\ADRIAN\BAKALARKA\DATASET\vsetko2\panasonic_fullhd_01-090-045-202111091200.jpg', 'E:\ADRIAN\BAKALARKA\DATASET\vsetko3\fullhd-090-000-201901101000-01.png','E:\ADRIAN\BAKALARKA\DATASET\vsetko2\panasonic_fullhd_01-090-000-202109091400.jpg','E:\ADRIAN\BAKALARKA\DATASET\vsetko2\panasonic_fullhd_01-090-000-202110090800.jpg','E:\ADRIAN\BAKALARKA\DATASET\vsetko2\panasonic_fullhd_01-090-000-202103091300.jpg','E:\ADRIAN\BAKALARKA\DATASET\vsetko3\fullhd-090-000-201901102200-01.png'};
% Vymazanie riadkov s danými cestami
for i = length(pathsToDelete):-1:1
    idx = strcmp(LabelData.imageFilename, pathsToDelete{i});
    LabelData(idx, :) = [];
end
% Uloženie upravenej tabuľky
save('LabelData.mat', 'LabelData');
