+class LambApplyWeightAssign(PrimitiveWithInfer):
+    r"""
+    Updates gradients by LAMB optimizer algorithm. The weight update part.
+
+    The Lamb optimzier is proposed in `Large Batch Optimization for Deep Learning: Training BERT in 76 minutes
+    <https://arxiv.org/abs/1904.00962>`_.
+
+    The updating formulas are as follows,
+
+    .. math::
+        \begin{array}{ll} \\
+            m = \beta_1 * m + (1 - \beta_1) * g \\
+            v = \beta_2 * v + (1 - \beta_2) * g * g \\
+            m = \frac{m}{1 - \beta_1^t} \\
+            v = \frac{v}{1 - \beta_2^t} \\
+            r = \frac{m}{\sqrt{v} + \epsilon} \\
+            w = w - l * \frac{\left \| w \right \|}{\left \| r \right \|} * (r + \lambda * w))
+        \end{array}
+
+    :math:`m` represents the 1st moment vector, :math:`v` represents the 2nd moment vector, :math:`g` represents
+    `gradient`, :math:`l` represents learning rate `lr`, :math:`\beta_1, \beta_2` represent `beta1` and `beta2`,
+    :math:`t` represents updating step while :math:`beta_1^t` and :math:`beta_2^t` represent `beta1_power` and
+    `beta2_power`, :math:`\lambda` represents `weight_decay`, :math:`w` represents `var`, :math:`\epsilon` represents
+    `epsilon`.
+
+    Inputs:
+        - **w_norm** (Tensor) - :math:`\left \| w \right \|` in the updating formula, float32/float16.
+        - **g_norm** (Tensor) - :math:`\left \| r \right \|` in the updating formula, has the same type as `w_norm`.
+        - **lr** (Tensor) - :math:`l` in the updating formula, the learning rate, float32/float16.
+        - **update** (Tensor) -:math:`r + \lambda * w`in the updating formula, float32/float16.
+        - **var** (Tensor) - Weights to be updated, the same shape and type as `update`.
+
+    Outputs:
+        - **var** (Tensor) - Weights to be updated in place, the same shape and type as `var` in inputs.
