filter(func) | 返回一个新的RDD,该RDD由经过func函数计算后返回值为true的输入元素组成 | flatMap(func) | 类似于map,但是每一个输入元素可以被映射为0或多个输出元素(所以func应该返回一个序列,而不是单一元素) | mapPartitions(func) | 类似于map,但独立地在RDD的每一个分片上运行,因此在类型为T的RDD上运行时,func的函数类型必须是Iterator[T] => Iterator[U]| mapPartitionsWithIndex(func) | 类似于mapPartition...
\cdot F(x_i; \theta_F)_{1:m}; y_i)$$其中,$L: \mathbb{R}^{L \times [L]} \rightarrow \mathbb{R}^+$是多类softmax交叉熵损失函数,而$F(\cdot; \theta_F): X \rightarrow \mathbb{R}^d$是由参数$\theta_F$参数化的深度神经网络,N是数据点的数量,L是类别的数量。这种方法的核心思想是**学习不同粒度的信息,允许一个嵌入向量在保持准确性和丰富性的同时,适应不同计算资源的需求,并可以无缝地适应大多数表示学习框架**,并且可...
