=== 模型效果优化 === 训练完成后,可以根据生成结果对模型进行优化: * '''手动检查输出''':给模型输入一些测试性的开头歌词或主题,让模型生成歌词片段。人工评估其连贯性、押韵、风格是否符合预期。根据观察结果决定是否需要进一步微调或调整数据。例如发现模型总是重复某些词,可以在训练数据中检查并减少类似重复样本,或者引入更多样本丰富表达。 * '''调节温度和长度''':在生成文本时,可调整'''温度(temperature)参数控制创造性,高温度会让输出更多样化但可能降低连贯性;Top-k采样或Top-p (nucleus)采样'''策略也可以帮助平衡多样性和流畅度。在测试不同参数组合后,选择效果最佳的用于最终应用。 * '''迭代训练''':可以通过'''持续训练'''(Continual Training)的方式逐步提升模型——先用基本数据训练模型,然后将模型生成结果与原始数据混合再训练(仿人类写作过程,不断润色)。不过要小心这种方法可能引入模型自有错误的放大。 通过上述训练和优化步骤,您应当能够得到一个在您数据集上表现良好的歌词生成模型。接下来,就可以考虑将模型部署供实际使用。
