这个深度学习项目的目标是训练一个模型使其能够自动玩俄罗斯方块并且在游戏中取得高分。通过使用神经网络我以游戏的状态作为输入然后模型将预测最佳的移动策略从而使方块能够正确地落下并消除行。通过反复训练和优化我希望能够让模型达到专业玩家的水平并且掌握一些高级策略。
本博客将详细介绍我在这个项目中所采用的深度学习方法和技术。我将分享我的代码实现并解释我在训练过程中所遇到的挑战和解决方案。无论你是对深度学习感兴趣还是对俄罗斯方块情有独钟这个项目都能够给你带来一些启发和思考。
我相信通过将深度学习和游戏开发相结合我们能够为游戏带来全新的可能性。让我们一起探索这个项目看看深度学习如何在俄罗斯方块这个经典游戏中展现其强大的应用能力吧
