QUESTION
I'm running several machine learning models to find the one which the highest accuracy score, however, all the accuracy scores are the exact same. I performed NLP on social media text and I'm training my models to tag sentiment based on sentiment determined from NLTK.
I'm using the same training and test sets, but I've done this method before in the past and received different scores on different models. Why are all of mine the same? Am I overfitting perhaps?
Here is my code where I'm splitting and training:
...ANSWER
Answered 2021-Jun-08 at 00:47I'm not sure what is the cause of the problem, but since the output of you SVM model and DecisionTreeClassfier always output 1, I suggest you try a more complex model like RandomForestClassifier and see what it comes out.
I've similar experience before, no matter how I tuned the training hyperparameters, the model always give the same performance metric -- this may cause by 2 probabilities:
- Our data is not suitable for the model, for example all values in the vector is zero: [0, 0, 0, 0, 0, 0, 0]
- Our model is too simple, which could only perform linear modeling, so that it could not learn too complex mapping function.
Since your SVM is built with linear kernel, could you try an more complex model and see what it comes out? And could you examine that if your X_train_vectors is all zero's in the matrix?

IE00B0M62Q58 = pd.read_csv('ETF/sample.csv', sep=',', decimal=',')
Also if .
it is a digit separator and 2.404,61

QUESTION
My idea is to track crude oil commodity prices and trade an ETF based on the movements of Oil.
Logic is:
- If price crosses SMA100 upwards trending for Oil, buy ETF
- If price crosses SMA100 downwards trending for oil, sell ETF
I use a generic SMA strategy but I cannot make it use the data from oil. Based on the plot it uses SMA 100 for the ETF.

I'm trying to import the value of an ETF stock using IMPORTXML via Google Sheets. From the URL : https://www.justetf.com/en/etf-profile.html?isin=DE000A1DCTL3. What I have so far:
=IMPORTXML("https://www.justetf.com/en/etf-profile.html?isin=DE000A1DCTL3","//div[@class='col-xs-6']/div[@class='val']")
This outputs:
EUR 141.56
EUR 2,932 m
0.15% p.a.
I would only like the Value of 141.56 to be output to the cell but I am unsure how to do this. Any help would be very much appreciated.

I am trying to download historical prices using yahoo finance for a few mutual funds and ETFs. I think there is a bug in Yahoo finance that confuses the scales of the prices (I don't think is a split issue. See pics below).
In any case here is a MWE to reproduce the problem

Answered 2021-Apr-28 at 20:34I checked SGLN.L quickly only yahoo's finance page And the data aligns. I'm not a market expert so I can't say what's going on here but that data seems to match. Also the volume up/down becomes a lot more volatile during that period so that could have something to do with it.
