Why ctree is only returning a single terminal node in this case?

Asked 2021-May-16 at 10:22

Introduction

I'm learning the basics of AI. I have created a .csv file with random data to test Decision Trees. I'm currently using R in Jupyther Notebook.

Problem

Temperature, Humidity and Wind are the variables which determine if you are allowed to fly or not.

When I execute ctree(vuelo~., data=vuelo.csv) the output it's just a single node when I was expecting a full tree with the variables (Temperatura, Humdedad, Viento), as I resolved on paper.

The data used is the next table:

Answer

ctree only creates splits if those reach statistical significance (see ?ctree for the underlying tests). In your case, none of the splits do so, and therefore no splits are provided.

In your case, you could force a full tree by messing with the controls (see ?ctree and ?ctree_control), e.g. like this:

I want to make an outer class that contains the name and age of a man and the inner class contains the age of a man.... I tried this way but VSC told me that this is a syntax error

why numpy allows mixed datatypes but docs say that it cannot

Asked 2021-May-11 at 13:55

I have a general question but no one is able to give me answer of that i did lot of search in official docs of python and other sources such as bootcamp and datacamp.

Issue is that i have read every where that numpy does not support hetrogenous data types (OFFICIAL DOCS)

But, when i write the code below it works fine. So, if numpy does not support heterogenous data types then why coding allows??

How to add values from given dataset into empty dictionary

Asked 2021-Mar-02 at 18:13

Below code copyrighted by Datacamp from Python course exercise that I am taking.
I have been given a csv file and The dataset contains Twitter data and I had to iterate over entries in a column to build a dictionary in which the keys are the names of languages and the values are the number of tweets in the given language. The resulting code is correct and working. However , I cannot quite understand how code works in the if-else statement part.
The output of the code is: {'en': 97, 'et': 1, 'und': 2}
My question is: How can we get the given output above. What happens exactly inside the code in for loop and if-else.

Answered 2021-Feb-28 at 14:43

I added some explanatory notes in the for | if | else to improve the understanding of the code as requested.

I changed the dataset to a minimum example, for the simplicity to explain.

As a general tip: Pandas has a built-in method (value_counts) that does the same.

Cosine similarity between a combination of numerical and text values

Asked 2021-Feb-27 at 15:02

ANSWER

Answered 2021-Feb-27 at 15:02

Let us assume that the CountVectorizer gives you a matrix C of shape (N, m) where N = number of restaurants and m = number of features (here the count of the words).

Now since you want to add numerical features, say you have k such features. You can simply compute these features for each movie and concatenate them to the matrix C. So for each movie now you will have (m+k) features. The shape of C will now be (N, m+k). You can use pandas to concatenate.

Now you can simply compute the Cosine Similarity using this matrix and that way you are taking into account the text features as well as the numeric features

However, I would strongly suggest you normalize these values, as some of the numeric features might have larger magnitudes which might lead to poor results. Also instead of the CountVectorizer, TFIDF matrix or even word embeddings might give you better results

Asked 2021-Feb-07 at 15:21

I've been using DataCamp to learn SQL. The first statement returned correct but the second returned incorrect. I'm having a hard time understanding why the second is incorrect since the aliasing should make them equivalents.

Statement 1

SELECT c.name AS city, l.name AS language FROM cities AS c CROSS JOIN languages AS l

ANSWER

Answered 2021-Feb-07 at 15:21

Yes, table alias renames the table in the context of the query, making the original name inaccessible.

For example, from PostgreSQL documentation:

The alias becomes the new name of the table reference so far as the current query is concerned — it is not allowed to refer to the table by the original name elsewhere in the query.
