1. Grammatical correction

Purpose : Polishing articles, papers, etc.

2. Text translation

Uses : daily study, business translation, etc.

3. Language conversion

3-1、Python–>JAVA

Purpose : For work purposes, it is more convenient for cooperation between different language engineers.

4. Code Explanation-1

Purpose : When we come to a new company and find that the former engineer has left a pile of codes that no one can understand, at this time, if someone can help us explain what these codes mean, then we will not be too happy.

    """

    2、第二次使用z-score来处理异常点：一种基于统计方法的时序异常检测算法借鉴了一些经典的统计方法，比如Z-score和移动平均线
    该算法将时间序列中的每个数据点都看作是来自一个正态分布，通过计算每个数据点与其临接数据点的平均值和标准差，可以获得Z-score
    并将其用于检测异常值，将z-score大于3的数据点视为异常值，缺点：如果异常点太多，则该算法的准确性较差。

5. Code Explanation-2

Remarks : In the previous code explanation, we can see that the answer may be affected by the comments in the code. Let's delete the comments and try again. For some points in the explanation that we don't understand, we can continue to ask!

import numpy as np
from sklearn.ensemble import IsolationForest
import plotly.express as px
import matplotlib.pyplot as plt
from sklearn.cluster import KMeans
import json

def Fusion_algorithm(y_list):
    for i in range(1, len(y_list)):
        difference = y_list[i] - y_list[i - 1]
        if difference <= 0:
            y_list[i] = y_list[i - 1]
    
        # else:
        #     if abs(difference) > 2 * np.mean(y_list[:i]):
        #         y_list[i] = y_list[i - 1]


    ma = np.mean(y_list)
    std = np.std(y_list)
    z_score = [(x - ma) / std for x in y_list]
    for i in range(len(y_list)):
        if z_score[i] > 3:
            print(y_list[i])
            y_list[i] = y_list[i - 1]

    return y_list

6. Fix code errors

Purpose : Find an error after writing a piece of code? Let chatGPT help you!

### Buggy Python
import Random
a = random.randint(1,12)
b = random.randint(1,12)
for i in range(10):
    question = "What is "+a+" x "+b+"? "
    answer = input(question)
    if answer = a*b
        print (Well done!)
    else:
        print("No.")

7. As an encyclopedia

Uses : chatGPT can explain all your questions! However, the function of listing novels is a bit stretched. After testing, only the science fiction column is okay, and other genres are not so good. Maybe the chatgpt training engineer is a science fiction fan!

8. Information Extraction

Purpose : As a large model in the field of natural language processing , how can information extraction be missing?

9. Chatting with friends

Purpose : Enter the character of the other party to simulate chatting. The function in this aspect is not perfect, and there may be new ways to play that I haven't discovered yet.

10. Idea Generator

Purpose : Do you often encounter thinking bottlenecks in innovation and don't know how to do it? Don't worry, let chatGPT help you generate ideas!

10-1. Combination of VR and Chamber of Secrets

10-2. Combined with AR

11. Interview Questions

Purpose : Maybe you are a media worker and don't know how to write interview questions? chatGPT can help you solve it.

11-1. List of interview questions

11-2. List of interview questions and give corresponding answers

12. Thesis Outline

Purpose : This function is not too cool for graduate students. I have been depressed about how to write the outline. Listing the outline directly has really helped me a lot! For points that are not understood in the outline, directly ask chatGPT for further explanation. Codes are also available! The content of that chapter is not very good at writing, so let chatGPT arrange it directly, so that a paper will be written soon!

12-1. Create a thesis outline

12-2. Explain the content of the outline

class PBA(nn.Module):
    def __init__(self, PerformanceThreshold, DistributionType, AttentionWeightRange):
        super(PBA, self).__init__()
        self.PerformanceThreshold = PerformanceThreshold
        self.DistributionType = DistributionType
        self.AttentionWeightRange = AttentionWeightRange
        
    def forward(self, input, performance_scores):
        # 计算注意力分数
        attention_scores = []
        for i in range(len(input)):
            if performance_scores[i] > self.PerformanceThreshold:
                attention_scores.append(performance_scores[i])
            else:
                attention_scores.append(0.0)
                
        # 将性能分数映射到注意力权重
        if self.DistributionType == "softmax":
            attention_weights = F.softmax(torch.tensor(attention_scores), dim=0)
        elif self.DistributionType == "sigmoid":
            attention_weights = torch.sigmoid(torch.tensor(attention_scores))
        else:
            raise ValueError("Unknown distribution type: {}".format(self.DistributionType))
        
        # 缩放注意力权重到指定范围
        attention_weights = attention_weights * (self.AttentionWeightRange[1] - self.AttentionWeightRange[0]) + self.AttentionWeightRange[0]
        
        # 计算加权输入
        weighted_input = torch.mul(input, attention_weights.unsqueeze(1).expand_as(input))
        output = torch.sum(weighted_input, dim=0)
        
        return output

13. Story Creation

Purpose : This function is really awesome. I can write novels after I make an outline myself!

13-1. Love story

13-2. Horror stories

Fourteen, problem analogy

Uses : This is a great feature when you want to make a metaphor.

15. Create SQL requirements

Purpose : Writing SQL is sometimes a headache, and I can't remember it for a long time.

16. Sentiment Analysis

Purpose : This function reminds me of the sentiment analysis task I did in the previous company.

17. Turn product descriptions into ads

Uses : This feature is awesome for merchants.

18. Keyword extraction

Purpose : The important role of NLP tasks, keyword extraction!

19. Chatbots

Purpose : Not much to say about this, it’s really good experience for chatting.

20. Summary

emmm, there are too many chatGPT chats for free today, the request request has been banned, so please request another day~
