在无源领域自适应问题中,通常情况下源域数据是不可访问的,因此无法直接使用源域数据来减少源域和目标域之间的差距。现有的无源领域自适应方法大多是隐式地对齐目标域和源域数据分布。本文提出了一种新的方法,利用源域模型和目标域数据构建源域代理特征,从而使得目标域数据与源域数据显示地对齐。[1]
与其他方法不同的是,本文使用了更稳健的伪标签策略,即spherical K-means聚类来估计源域分布,然后从中采样出源域代理特征,使得目标域分布能够显式地估计源域分布进行对齐,并适应于源域模型的分类器。这是本文的创新点。[3]
因此,本文的方法在解决无源领域自适应问题上与其他方法有所不同,通过构建源域代理特征并使用稳健的伪标签策略来实现目标域和源域的对齐。[1]

Free, built on open source
technologies, and customizable: these are some of the main advantages of using open source software. Open source is a term used to describe software whose source code is freely available to anyone who wants to access it, use it, modify it, or distribute it.
Open source technologies are often developed by communities of developers who collaborate to create software that is free and accessible to everyone. This approach leads to a vibrant ecosystem of tools and technologies that can be customized to meet the needs of specific users and organizations.
One of the main benefits of open source software is that it is free to use. This means that businesses and individuals can save money on software licenses and fees, making it a cost-effective solution for many organizations. Additionally, open source software is often more secure than proprietary software, as bugs and vulnerabilities are quickly identified and fixed by the community.
Open source software is also highly customizable. Users can modify the source code to suit their specific needs, creating a bespoke solution that meets their requirements. This flexibility makes open source software a popular choice for organizations with unique needs or specialized workflows.
Overall, the open source approach to software development offers many benefits to users and organizations. By leveraging the power of the community, businesses and individuals can access free, customizable, and secure software solutions that are built to meet their specific needs.

# 设置屏幕尺寸
screen_width = 800
screen_height = 600
screen = pygame.display.set_mode((screen_width, screen_height))
pygame.display.set_caption("简易游戏")
# 颜色设置
WHITE = (255, 255, 255)
RED = (255, 0, 0)
# 玩家设置
player_width = 50
player_height = 50
player_x = screen_width // 2
player_y = screen_height - player_height
player_speed = 5
# 敌人设置
enemy_width = 50
enemy_height = 50
enemy_x = random.randint(0, screen_width - enemy_width)
enemy_y = 0
enemy_speed = 3
# 游戏结束标志
game_over = False
# 游戏主循环
while not game_over:
for event in pygame.event.get():
if event.type == pygame.QUIT:

if keys[pygame.K_LEFT]:
player_x -= player_speed
if keys[pygame.K_RIGHT]:
player_x += player_speed
# 更新敌人位置
enemy_y += enemy_speed
# 碰撞检测
if player_x < enemy_x + enemy_width and player_x + player_width > enemy_x and player_y < enemy_y + enemy_height and player_y + player_height > enemy_y:
game_over = True
# 刷新屏幕
