+## Part 3: A simple visualization (`python demo.py`)
+To visualize the result, 
+```
+python demo.py --query_index 777
+```
+`--query_index ` which query you want to test. You may select a number in the range of `0 ~ `.
+
+It is similar to the `evaluate.py`. We add the visualization part.
+```python
+try: # Visualize Ranking Result 
+    # Graphical User Interface is needed
+    fig = plt.figure(figsize=(16,4))
+    ax = plt.subplot(1,11,1)
+    ax.axis('off')
+    imshow(query_path,'query')
+    for i in range(10): #Show top-10 images
+        ax = plt.subplot(1,11,i+2)

+## Part 4: Your Turn. 
+
+- University-1652 is a dataset collected in normal weather.
+
+Let's try another dataset called University-WX, which simulates different weathers.
