kandi X-RAY | rattle Summary
Rattle is an EVM binary static analysis framework designed to work on deployed smart contracts. Rattle takes EVM byte strings, uses a flow-sensitive analysis to recover the original control flow graph, lifts the control flow graph into an SSA/infinite register form, and optimizes the SSA – removing DUPs, SWAPs, PUSHs, and POPs. The conversion from a stack machine to SSA form removes 60%+ of all EVM instructions and presents a much friendlier interface to those who wish to read the smart contracts they’re interacting with.

QUESTION
Im trying to create a simple program that reads strings entered by the user and displays the longest and shortest string. The program works fine for single words such as 'dog' or 'cat' but if I was to type 'rattle snake' it takes it as two individual words 'rattle' and 'snake' and not one whole string with a space included. Is there any reason why its registering the space as a divider/separator and not treating it as one whole string? Thank you!

I would like to make an infinite string with a number. What is the best way to do this here e.g. mt_rand(1000000, 9000000)
but if between 1000000
and 9000000
everything is occupied there are no more numbers. The more numbers are used the more often there are errors, and the if else has to rattle through the whole table again and again.

My bank provides a very poor excuse for transaction export which makes doing reconciling receipts for taxes way more difficult than it needs be, fortunately their web site is an SPA that is chock-full of rich json formatted data.
Having extracted all of the transaction data for a year, I'd now like to transform that data into filenames (date - cat - desc - amt.pdf
) to use for receipt scans to help speed up the reconciling process.
I'm close to being able to do this but a doing a double lookup has stumped me and I could use the help of someone more well versed in jq

Answered 2021-May-25 at 15:17If you are going tidymodels and parsnip to fit your model, it's better to use that actual fitted model for any visualizations like this. You can get the underlying engine object from a parsnip model using $fit

QUESTION
I am using XGBClassifier for the Rain in Australia dataset and trying to predict whether it will rain today or not. I wanted to tune the hyperparameters of the classifier with GridSearch and score it with ROC_AUC. Here is my code:
...ANSWER
Answered 2021-Apr-10 at 08:20Have you tried your own roc_auc scoring rule? It seems like you are passing labels instead of probabilities (you originally need) for roc_auc.
problem described in here: Different result roc_auc_score and plot_roc_curve
Solutions for own scorers: Grid-Search finding Parameters for AUC
Update2
Sorry, saw today that my introduction text from the notebook was missing lol
When calculating roc_auc_score you have the option (it doesnt matter, if it is with or without gridsearch, with or without pipeline) that you can pass it labels like (0/1) or probabilities like (0.995, 0.6655). The first should be easy available if you just convert your probas to labels. However that would result in a (straight reversed L) output plot. That looks sometimes ugly. the other option is to use predicted probabilites to pass them them to the roc_auc_score. That would result in a (staircase reversed L) output plot, which looks much better. So what you first should test is, can you get a roc auc score with labels, with and without grid, if that is the case. You should then try to get probabilities. And there, I believe, you have to write your own scoring method, as the roc-auc_score in grid only serves labels, that would result in high roc_auc scores. I wrote something for you, so you can see the label approach:
