kandi X-RAY | SOFA Summary
This repository is the implementation of SOFA, the Simulator for OFfline leArning and evaluation. Keeping Dataset Biases out of the Simulation: A Debiased Simulator for Reinforcement Learning based Recommender Systems. Jin Huang, Harrie Oosterhuis, Maarten de Rijke, Herke van Hoof. Recsys 2020. The framework shows how RL4Rec typically interacts with a simulation-based environment. A state is user historical interactions, an action is an item being recommended bytheRS, and a reward is related to user feedback. As a solution to the effect of bias present in logged data, we introduce a debiasing step in the simulation pipeline, which corrects for the biases present in the logged data before it is used to simulate user behavior.

In the view, you can zip bar

I have a list of functions and values I'd like to put into a nested list. I'd like the result to be a LISP style list(something that looks close to some LISP style executable code) that I can easily process later. This list comes from a "sentence", that gets split into a list by word - it keeps defined phrases (multi word) together, by checking any multi-word tokens in the DB first, gluing them and then separating them later. Any words not in the database are ignored. Punctuation is also ignored. It just matches actual stored Tokens. This lets me write a sentence that can get translated into functions I can process later. We can ignore the fact that these are functions, and just think of them as strings, since that's how they're stored, but functions and arguments describe the use case perfectly, since that's what they are. Functions will be the first item in a list, followed by their arguments in the same list. A function with no arguments will be in a list with only that one element. An argument that is itself a function will be in a list(with it's arguments, if any). The number of arguments is each function takes is preset, and won't vary (it could call other functions that take their own arguments though). Should technically be able to go infinitely deep, though I'm sure a few levels will suffice if limiting helps. This is a recursive type problem so depth level shouldn't really matter. If it helps, I'm using Django, and so have access to any model methods there, since Token is a Model, as are the sentences.
I'm calling the list items "Tokens". They can be more than one word. They're actually stored in a database. Each Token can have: symbol, val, kind Symbol: Pretty format string to search for in sentence Value: The thing we want in the list Kind: An integer; number of args or code for other kinds
KIND_CHOICES = [ (0, 'Argless Function'), (1, '1-Arg Function'), (2, '2-Arg Function'), (3, '3-Arg Function'), (4, '4-Arg Function'), (6, 'Value'), (7, 'Ignore'), ]
Let's use these Tokens for an example: ("Symbol",'val',kind)
("Walk",'walk',1) ("To",'to',1) ("Sandwich Shop",'sandwich-shop',6) ("Order",'place_order',2) ("Toasted",'toast',1) ("Sandwich",'sandwich',6) ("Dine-In",'here',0) ("Eat",'eat',1) ("Back",'back',1) ("Home",'residence',6) ("Nap",'sleep',0) ("on the sofa",7)
Here's an example sentence:
Walk To the Sandwich Shop, Order your favorite Toasted Sandwich for Dine-In, Eat your Sandwich, Walk Back Home, then finally Nap on the sofa.
The first list I'll end up with from my current working cleanup functions gives us:
['walk','to','sandwich-shop','place_order','toast','sandwich','here','eat','sandwich','walk','back','residence','sleep']
then, finally (the part I just can't get right! I'm off by one, get duplicates, missing tokens, or the wrong structure)
[['walk',['to','sandwich-shop']],['place_order',['toast','sandwich'],['here']],['eat','sandwich'],['walk',['back','residence']],['sleep']]
Some of my attempts have involved using a repeated placeholder string for the arguments, with various replace_or_append implementation attempts; inserting empty elements in a list for arguments, then using a put_in_next_empty_spot implementation(a few tries at that); and some simpler looping with an incremented index and pop. I'm just stuck on this for some reason and could use some brainpower on what seems like it should be a pretty simple problem to solve.
Here's some example code from one terribly failed attempt:

Answered 2021-May-27 at 18:26To build the nested lists based on the argument specifications, you can use recursion with collections.deque
. By using the reference to the deque
passed to nest_tokens
, you can mutate the tokenized result in-place by popping off the number of arguments required for a "function":

QUESTION
I was told to turn a functional auto for loop that goes through all the rooms in the house into a while loop that allows the user to type what room they go into next.
The issue is you need to use the array and scanner in the while loop and I am struggling to think on how to do this, the array somehow needs to be part of the condition in the while loop and I need to be able to type what room I want to access in the array without modifying the string values in my rooms array.
Am I overthinking this?
...ANSWER
Answered 2021-May-04 at 18:39You reference array values via [index] where index starts from 0.
Instead of switch use if else statement (you can't use switch with array value since switch requries compile time constants), like so:

Install SOFA
You can use SOFA like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
