Deep learning has been applied to many studies in high energy physics with substantial improvement over the traditional selection-cut methods. Based on deep-learning approaches, we perform a comprehensive signal-background analysis for Higgs-pair production in $HH \rightarrow b \bar{b} \gamma\gamma$ channel at the HL-LHC, with the goal of probing the self-coupling $\lambda_{3H}$ of the Higgs boson. We show that the multi-class classification using Deep Neural Network can indeed give better performance in disentangling signal and backgrounds.
