-## Examples 5: Predict(Classification)
-This task is a sentiment analysis task. The following sections detail model preparation, dataset preparation, and how to run the task.
+## Example 5: Prediction
+This example demonstrates how to directly do prediction with PaddlePALM. You can either initialize the model from a checkpoint, a pretrained model or just randomly initialization. Here we reuse the task and data in example 1. Hence repeat the step 1 in example 1 to pretrain data. 
 
-### Step 1: Prepare Pre-trained Models & Datasets
-
-#### Pre-trianed Model
-
-The pre-training model of this mission is: [ernie-zh-base](https://github.com/PaddlePaddle/PALM/tree/r0.3-api).
-
-Make sure you have downloaded the required pre-training model in the current folder.
-
-
-#### Dataset
-
-This task uses the `chnsenticorp` dataset. 
-
-Download dataset:
-```shell
-python download.py
-```
-
-If everything goes well, there will be a folder named `data/`  created with all the datas in it.
-
-The data should have 2 fields,  `label  text_a`, with tsv format. Here is some example datas:
-
-```
-label  text_a

-The code used to perform classification task is in `run.py`. If you have prepared the pre-training model and the data set required for the task, run:
