Soft softmax loss
Web6 Apr 2024 · 前言. 当前语义分割方式大都基于FCN或注意力机制的网络设计和基于参数化的softmax或像素查询的掩码解码策略,可以被归结为使用参数可学习模型(像是通过softmax学习或者Transformer中使用的向量查询,其参数都是可学习的),但是参数学习方式存在一定的局限性 ... Web29 Aug 2024 · When the temperature is low, both Softmax with temperature and the Gumbel-Softmax functions will approximate a one-hot vector. However, before convergence, the Gumbel-Softmax may more suddenly 'change' its decision because of the noise.
