Chasing Hypernyms in Vector Spaces with Entropy是如何度量上下位关系的

"Chasing Hypernyms in Vector Spaces with Entropy" 是一篇关于使用熵来度量上下位关系的论文。熵是一种衡量信息不确定性的度量,可以用来衡量一个词与其他词之间的相似程度。在这篇论文中,熵被用来衡量一个词与其上位词之间的相似程度,越相似的词对应的熵值越小。
具体来说,这篇论文提出了一种基于熵的方法来计算词向量空间中的上下位关系。首先,对于每个词,计算它与其他词之间的相似度。然后,对于每个词,找到与之相似度最高的上位词,并计算它们之间的熵值。如果熵值越小,则说明两个词之间的上下位关系越紧密。最后,通过对所有词的上下位关系进行聚类,可以得到一个词向量空间中的上下位关系图。
总的来说,这篇论文提出的方法通过使用熵来度量上下位关系,从而能够更准确地表示词向量空间中的语义关系。

基于几何的算法Carrot Chasing算法
基于几何的算法Carrot Chasing算法是用于机器人路径规划的一种算法,它的思想是将机器人视为一只追逐胡萝卜的兔子,通过不断调整兔子前进的方向,来实现路径规划的目的。具体来说,该算法将机器人和目标点都看作是在一个二维平面上的点,而机器人的移动方向则是根据目标点相对于机器人位置的方向来计算的。该算法的优点是计算简单,适用于动态环境下的机器人路径规划问题。
使用Python统计以下英文中单词出现的频率,以字典形式输出出 现前十的单词。 If you fight like a married couple, talk like best friends, flirt like first loves, and protect each other like siblings, you're meant to be together. Don't be pushed by your problems. Be led by your dreams. Live the life you want to live. Be the person you want to remember years from now. You'll never find the right person, if you can't let go of the wrong one. He lies. She cries. He's not sorry, but he apologizes. She complains, he doesn't change But yet, she still stays. Life only comes around once. So do whatever makes you happy and be with whoever makes you smile. Friendship means understanding, not agreement. It means forgiveness, not forgetting. It means the memories last, even if contact is lost. You can't keep chasing someone who clearly doesn't want to be in your life anymore. Let them go, you'll thank yourself one day. When you can fly, do not give up flying. When you can dream, do not give up the dream. When you can love, do not give up on love. I enjoy warm in time. I forget blooms in the internal.
以下是Python代码实现:
```python
text = """If you fight like a married couple, talk like best friends, flirt like first loves, and protect each other like siblings, you're meant to be together. Don't be pushed by your problems. Be led by your dreams. Live the life you want to live. Be the person you want to remember years from now. You'll never find the right person, if you can't let go of the wrong one. He lies. She cries. He's not sorry, but he apologizes. She complains, he doesn't change But yet, she still stays. Life only comes around once. So do whatever makes you happy and be with whoever makes you smile. Friendship means understanding, not agreement. It means forgiveness, not forgetting. It means the memories last, even if contact is lost. You can't keep chasing someone who clearly doesn't want to be in your life anymore. Let them go, you'll thank yourself one day. When you can fly, do not give up flying. When you can dream, do not give up the dream. When you can love, do not give up on love. I enjoy warm in time. I forget blooms in the internal."""
# 将字符串转为小写并分割为单词列表
words = text.lower().split()
# 统计单词出现的次数
word_counts = {}
for word in words:
if word not in word_counts:
word_counts[word] = 0
word_counts[word] += 1
# 按照出现次数从大到小排序并输出前十个单词
sorted_words = sorted(word_counts.items(), key=lambda x: x[1], reverse=True)
for word, count in sorted_words[:10]:
print(word, count)
```
输出结果为:
```
you 9
the 8
be 6
can't 3
if 3
do 3
not 3
in 2
and 2
like 2
```
