kandi X-RAY | steem Summary
Welcome to the official repository for Steem, the blockchain that will revolutionize the web, and soon the blockchain for Smart Media Tokens!. Steem is the first blockchain which introduced the "Proof of Brain" social consensus algorithm for token allocation. Being one of the most actively developed blockchain projects currently in existence, it's become fertile soil for entrepreneurial pursuits. It has also become home for many cryptocurrency centric projects. Steem aims to be the preferred blockchain for dApp development with Smart Media Tokens at its core. With SMTs, everyone can leverage the power of Steem. Originally, Steem was announced on the Bitcointalk forum prior to the start of any mining. (Steem is currently not mineable).

QUESTION
I try to filter out some specific data out of the list I get from an api request of a crypto price ticker.
This prints all the data:
...ANSWER
Answered 2021-Aug-03 at 13:46The data
variable is a list with dictionaries and the dictionaries have the values you want.So, you just need to dig in a bit deeper for the data you want.
- Firstly, access each dictionary in the list using a for loop
- Check if the "market" value for the current dictionary is among ["BTC-EUR","ETH_EUR"] or not
- If it is, print the price for those values
Try:
QUESTION
I built a sentiment analysis model in Arabic; in Python; after building the model, how can I test it with external data and how to build the code for that?
When I fitting the model, I extracted the features via tf-idf, and the problem I faced is dealing with it when I want to test external data after I trained the model on the training and test data.
summary : After I trained the model and reached an accuracy of 88%, I want to build a code that tests the model with external data..
...ANSWER
Answered 2021-Jul-12 at 14:19In order to test the model (use the model to predict on unseen data), you should use the .predict
or .transform
function (with sklearn).
In your code you separated the preprocessing functions and the model training functions which is good. But the fact that you combine the test and the train data is not good. The test data should be your "external data".
Also you tread the TfIdf as a preprocessing step applied to both the test and train data, but the tfidf_vectorizer.transform
should only be applied to the train data !
If you fit all your data in the TfIdf then you will not know how your model will behave when it haven't seen some words of the input.
With sklearn I usually organize my code as follow:
