Hi, kagglers!

\n

I’ve been trying to make 3 diff spectrograms(size: 512X512)

\n

Example1) 10m + 50s & 20s
\n
\nExample2) 10m + 50s two chains[ll,lp,rp,rr] + [others]
\n
\nBut it seems like not that effective than 10m & 50s spectrograms

\n

I’m curious if there’s person who improve score using 3diff spec
\nAnd how about your idea using 3diff spec
\nFeel free to tell me
