您好只是爲了熟悉我已經準備了二元分類飛機(760個圖像)或非飛機(750)的代碼的CNN。錯誤在訓練CNN的二元分類
這是我的MATLAB代碼
Npos = numel(possitive_regions);
Nneg = numel(negative_regions);
Npos_train = floor(0.25* Npos);
Npos_val = floor(0.25*Npos);
Npos_test = floor(0.50*Npos);
Nneg_train = floor(0.25*Nneg);
Nneg_val = floor(0.25*Nneg);
Nneg_test = floor(0.50*Nneg);
for i=1:Npos
im= imresize (single(possitive_regions{i,:}),[50,50]);
imdb.images.data(:,:,:, i) = im;
imdb.images.labels(i) = 1;
if i <= Npos_train
imdb.images.set(i) = 1;
elseif i <= Npos_train+Npos_val
imdb.images.set(i) = 2;
else
imdb.images.set(i) = 3;
end
end
% for negative samples
for i=1:Nneg
im= imresize (single(negative_regions{i,:}),[50,50]);
imdb.images.data(:,:,:, i+Npos) = im;
imdb.images.labels(i+Npos) = 0;
if i <= Nneg_train
imdb.images.set(Npos+i) = 1;
elseif i <= Nneg_train+Nneg_val
imdb.images.set(Npos+i) = 2;
else
imdb.images.set(Npos+i) = 3;
end
end
imdb.meta.sets = {'train', 'val', 'test'} ;

% [net, info] = trainfn(net, imdb, getBatch(opts), 'expDir', opts.expDir, net.meta.trainOpts, opts.train, 'val', find(imdb.images.set == 3)) ;

網絡部分我把它從MINST例子。我在MatConvNet示例文件夾中保存了該文件和getBatch函數。 當我運行cnn_train
我得到這個輸出和錯誤。
任何人,請幫我解決這個錯誤。 另外,我搜索了這個錯誤,我發現我需要檢查mex文件,並使用vl_compilenn('verbose',1)進行編譯。 我也編制,進行了一個錯誤:
使用錯誤MEX

vl_compilenn錯誤(第498行)mex_link(opts,objs,mex_dir, flags.mexlink);
你會得到什麼錯誤? – rpd
