Network Crawler Grabs Lottery Data and Analyses and Predictions 网络爬虫抓取彩票数据并且分析预测. 人工智能分析彩票算不出来,那只能人为的统计统计彩票数据了,可以统计彩票还能练练手. 之前写过一篇文章,用python爬虫程序网上抓取排列3全部历史数据,保存到本地,现在这篇是读取本地文件,开始展开分析. 反正程序写完之后,我感觉python最乱的是各种数据的互相转换,python的数据类型非常多,然后光看代码也不知道是什么数据类型,你调用不同的库函数,参数得是函数指定数据类型,所以数据类型得转换来转换去,转的我头晕眼花,说到底还是基础功力薄弱,光想着调用各种库模块,却不知道基本功不好的话库模块都调用不动. 试了多种python的IDE感觉还是spyder最好,主要它在调试运行程序时,显示各种数据的类型,写的非常详细全面.否则程序写长了光各种数据类型的转换就能把人搞的头晕眼花,怪不得连python之父都不想用python了.

QUESTION
I am working on Pima Indians Diabetes Database in Weka. I noticed that for decision tree J48 the tree is smaller as compared to the Random Tree. I am unable to understand why it is like this? Thank you.
...ANSWER
Answered 2022-Feb-21 at 19:57Though they both are decision trees, they employ different algorithms for constructing the tree, which will (most likely) give you a different outcome:
- J48 prunes the tree by default after it built its tree (Wikipedia).
- RandomTree (when using default parameters) inspects a maximum of
log2(num_attributes)
attributes for generating splits.
QUESTION
I tried to extract keywords from a text. By using "en_core_sci_lg" model, I got a tuple type of phrases/words with some duplicates which I tried to remove from it. I tried deduplicate function for list and tuple, I only got fail. Can anyone help? I really appreciate it.
...ANSWER
Answered 2022-Feb-09 at 22:08doc.ents
is not a list of strings. It is a list of Span
objects. When you print one, it prints its contents, but they are indeed individual objects, which is why set
doesn't see they are duplicates. The clue to that is there are no quote marks in your print statement. If those were strings, you'd see quotation marks.
You should try using doc.words
instead of doc.ents
. If that doesn't work for you, for some reason, you can do:

QUESTION
I have a pandas dataframe that is in the following format:
This contains the % change in stock prices each day for 3 companies MSFT, F and BAC.
I would like to use a OneClassSVM calculator to detect whether the data is an outlier or not. I have tried the following code, which I believe detects the rows which contain outliers.
...ANSWER
Answered 2021-Nov-04 at 09:28It's not very clear what is delta
and df
in your code. I am assuming they are the same data frame.
You can use the result from svm.predict
, here we leave it as blank '' if not outlier:
QUESTION
I was doing a machine learning task in Weka and the dataset has 486 attributes. So, I wanted to do attribute selection using chi-square and it provides me ranked attributes like below:
Now, I also have a testing dataset and I have to make it compatible. But how can I reorder the test attributes in the same manner that can be compatible with the train set?
...ANSWER
Answered 2021-Oct-08 at 00:07Changing the order of attributes (e.g., when using the Ranker in conjunction with an attribute evaluator) will probably not have much influence on the performance of your classifier model (since all the attributes will stay in the dataset). Removing attributes, on the other hand, will more likely have an impact (for that, use subset evaluators).
If you want the ordering to get applied to the test set as well, then simply define your attribute selection search and evaluation schemes in the AttributeSelectedClassifier meta-classifier, instead of using the Attribute selection panel (that panel is more for exploration).
