            How to use a rule-based 'expert' for imitation learning?
            Asked 2022-Apr-09 at 12:30

            I am currently training a PPO model for a simulation. The PPO model fails to understand that certain conditions will lead to no reward.

            These conditions that lead to no reward are very simple rules. I was trying to use these rules to create an 'expert' that the PPO model could use for imitation learning.

            Example of Expert-Based Rules:

            If resource A is unavailable, then don't select that resource.

            If "X" & "Y" don't match, then don't select those.

            Example with Imitations Library

            I was looking at the "imitations" python library. The example there shows an expert that is a PPO model with more iterations.

            https://github.com/HumanCompatibleAI/imitation/blob/master/examples/1_train_bc.ipynb

            Questions:

            Is there a way to convert the simple "rule-based" expert into a PPO model which can be used for imitation learning?

            Or is there a different approach to using a "rule-based" expert in imitation learning?

            What is the equivalent of a SnackBar in Swift/iOS
            Asked 2022-Mar-21 at 04:21

            I'm currently working on porting an Android application to iOS. One crucial part of the user-interface is an Android Snackbar; a small box at the bottom of the screen alerting the user of something, while not being a full-fledged dialog. SnackBar image.

            I tried using different methods of the built-in UIAlertView from this post: How to implement a pop-up dialog box in iOS? but there was nothing like what I'm inquiring.

            I would like to know also if this is even possible with Swift, and if I will have to redesign around this problem. As well as if there are any Github repos or the like to provide a framework.

            I have done some research, and have not found any posts that answer my problem. The post at How to implement a pop-up dialog box in iOS? is not really at all what I'm looking for, even though I do realize now that there are frameworks out there to work around this issue, and realize that this is indeed possible. My only question now is what are the best frameworks to use for Snackbar imitation.

            My question has been answered.

            SnackBar (along with Toast, PopupDialog, etc.) is a concept baked into Android, and there's no equivalent on iOS.

            You can:

            • create a custom component, and handle fly-in and fly-out animations, or,
            • use external libraries. My go-to is ahmedAlmasri's SnackBar.swift, which resembles a lot of that on Android.

            mock_open() mocks the open() builtin function.

            Just as you wouldn't do json.loads(open), you can't do json.loads(mock_open()).

            On top of that, json.loads() receives a string and not a file. For that use json.load().

            So I'd do something as follows:

            1. Save a reference to your counter job: private var counterJob: Job? = null
            2. Update it when needed: counterJob = launch { counter() }
            3. Cancel it when needed: counterJob?.cancel()

            Removing partial duplicates within the same column, while retaining the longer text?
            Asked 2021-Jun-22 at 08:39

            so I'm new to Python and I was looking to remove partially similar entries within the same column. For example these are the entries in one of the columns in a dataframe-

            Row 1 - "I have your Body Wash and I wonder if it contains animal ingredients. Also, which animal ingredients? I prefer not to use product with animal ingredients."

            Row 2 - "This also doesn't have the ADA on there. Is this a fake toothpaste an imitation of yours?"

            Row 3 - "I have your Body Wash and I wonder if it contains animal ingredients. I prefer not to use product with animal ingredients."

            Row 4 - "I didn't see the ADA stamp on this box. I just want to make sure it was still safe to use?"

            Row 5 - "Hello, I was just wondering if the new toothpaste is ADA approved? It doesn’t say on the packaging"

            Row 6 - "Hello, I was just wondering if the new toothpaste is ADA approved? It doesn’t say on the box."

            So in this column, rows 1&3, and rows 5&6 are similar (partial duplicates). I want python to recognize these as duplicates, retain the longer sentence and drop the shorter one and export the new data to a csv file.

            Expected output - Row 1 - "I have your Body Wash and I wonder if it contains animal ingredients. Also, which animal ingredients? I prefer not to use product with animal ingredients."

            Row 2 - "This also doesn't have the ADA on there. Is this a fake toothpaste an imitation of yours?"

            Row 3 - "I didn't see the ADA stamp on this box. I just want to make sure it was still safe to use?"

            Row 4 - "Hello, I was just wondering if the new toothpaste is ADA approved? It doesn’t say on the packaging"

            I tried using FuzzyWuzzy wherein I used the similarity sort function, but it didn't give me the expected output. is there any simpler code for this?

            How do I merge the elements of two collections while cycling the first in Clojure?
            Asked 2021-Apr-03 at 11:15

            How would one elegantly take these two inputs:

            (def foo [:a 1 :a 1 :a 2])

            (def bar [{:hi "there 1"}{:hi "there 2"}{:hi "there 3"}{:hi "there 4"}{:h1 "there 5"}])

            and get:

            [{:hi "there 1" :a 1}{:hi "there 2" :a 1}{:hi "there 3" :a 2}{:hi "there 4" :a 1}{:hi "there 5" :a 1}]

            The first collection cycles at the point the second collection reaches the same number of elements. It would be fine for the first collection to be any of these as it's going to be hard coded:

            (def foo [{:a 1} {:a 1} {:a 2}])

            (def foo [[:a 1] [:a 1] [:a 2]])

            (def foo [1 1 2])

            There may be another data structure that would be even better. The 1 1 2 is deliberate as it's not 1 2 3 which would allow range or something like that.

            Cycling through the first collection is easy... I'm not sure how to advance through the second collection at the same time. But my approach may not be right in the first place.

            As usual, I tend toward weird nested imitations of imperative code but I know there's a better way!

            ...

            Here's one way to do it:

            You can take the values from foo, cycle through them and partition them in groups of 2 at a time. There's a little secret of vectors of size 2, which is that they can work as a little map (1 key/value pair).

            Once we have two collections of maps, we can merge them together. One collection is infinite but that's OK, map will compute only the values until one collection runs out of elements. mapv is the same as map but it returns a vector instead.

            Install imitation

            You can install using 'pip install imitation' or download it from GitHub, PyPI.
            You can use imitation 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.
