+### [tf.losses.mean_and_squared_error](https://www.tensorflow.org/api_docs/python/tf/losses/mean_squared_error)
+
+``` python
+tf.losses.mean_squared_error(
+    labels,
+    predictions,
+    weights=1.0,
+    scope=None,
+    loss_collection=tf.GraphKeys.LOSSES,
+    reduction=Reduction.SUM_BY_NONZERO_WEIGHTS
+)
+```
+
+
+### [paddle.fluid.layers.square_error_cost](http://paddlepaddle.org/documentation/docs/zh/1.3/api_cn/layers_cn.html#paddle.fluid.layers.square_error_cost)
+``` python
+paddle.fluid.layers.square_error_cost(
+    input, 
+    label
+)
+```
+### 功能差异
+
+#### 计算方式
+TensorFlow: 提供`weights`参数，通过传入`weights`参数的shape，可实现不同的加权方式；
+PaddlePaddle：不支持加权。
