            Which Shap-Explainer fits my requirements
            Asked 2021-Jun-08 at 00:11

            i have created a CNN with Keras and Tensorflow as my backend and my data consists of 2D images which represent EEG (Electroencephalography)-data from the preprocessed DEAP-Dataset.

            I have considered to use SHAP as the model explainer but since there are several shap-explainers (kernel, deep, linear, gradient...) I am not sure which one fits my needs the most or if even SHAP could be helpful in my case. Since my images (Dimensions:40x100x1, the third dimension comes from np.expand_dims, since keras needs 3D images) have no colors, is SHAP even a considerable approach?

            There are no limitations to the use of SHAP for model explanations as they are literally meant to

            explain the output of any machine learning model

            (compare with the docs)

            There are indeed several core explainers available. But they are optimized for different kinds of models. Since your case consists of a CNN model built with TensorFlow and Keras, you might want to consider the following two as your primary options:

            • DeepExplainer: meant to approximate SHAP values for deep learning models.

            • GradientExplainer: explains a model using expected gradients (an extension of integrated gradients).

            Both of these core explainers are meant to be used with Deep Learning models, in particular such built in TensorFlow and Keras. The difference between them is how they approximate the SHAP values internally (you can read more about the underlying methods by following the respective link). Because of this, they will very likely not return the exact same result. However, it is fair to assume that there won't be any dramatic differences (although there is no guarantee).

            While the former two are the primary options, you might still want to check the other core explainers as well. For example, the KernelExplainer can be used on any model and thus, could also be an option on Deep Learning models. But as mentioned earlier, the former two are particularly meant for Deep Learning models and should therefore (probably) be preferred.

            Since you are using pictures as input, you might find the image_plot useful. Usage examples can be found on the GitHub repository you already linked to. You also do not need to worry about colors as they do not matter (see the DeepExplainer MNIST example).

            numpy genetic algorithm selection: roulette wheel vs. stochastic universal sampling
            Asked 2021-Jan-12 at 20:59

            I am implementing a genetic algorithm in numpy and I'm trying to figure out how to correctly implement selection via roulette wheel and stochastic universal sampling. The examples I've seen on stackoverflow or elsewhere use a python loop rather than vectorized numpy code.

            For example, here are the implementations of both algorithms in DEAP.

            ANSWER

            Answered 2021-Jan-12 at 20:59

            Both strategies can possibly select the same individual multiple times, so replacement is not the point.

            I don't know how np.random.choice is implemented internally, but anyway the implementation method is not specified in the contract of the function (and so it could change at any time). Below I give my implementation of both selection strategies using numpy. Please, make sure to test these functions before using them in anything serious.

            You could use the Python built-in function getattr, which lets you get attributes of an object by name.

            As explained in the docs: getattr(x, 'foobar') is equivalent to x.foobar.

            Answered 2020-Sep-22 at 05:37

            I've got some experience with rasterio, but I am not nearly a master with it. If I remember correctly, rasterio requires you to have installed the program GDAL(both binaries and python utilities), and some other dependencies listed on the PyPi page. I don't use conda at the moment, I like to use the regular python 3.8 installer with pip. Given what I'm seeing with your installation, I would uninstall rasterio and follow a different installation procedure.

            I follow the instructions listed here: https://rasterio.readthedocs.io/en/latest/installation.html
            This page also has separate instructions for those using Anaconda.

            The GDAL installation is by far the most annoying but once it's done, the hard part is over. The python utilities for both rasterio and gdal can be found here:
            https://www.lfd.uci.edu/~gohlke/pythonlibs/#gdal
            The second link is also provided on the PyPi page but I like to keep it bookmarked because there's a lot of good resources there!

            The reason

            I now know what happend here. When this question was originally asked, the image in question did not have the make command inside it.

            Adding RUN apt-get install -y build-essential to the Dockerfile solves the issue. But, this image is built on dockerhub, so when the image was rebuilt after adding this instruction - it was not refreshed locally. You would actively need to pull the image again like I mention later in this answer.

            I verified this, but rebuilding the image from your original Dockerfile definition and confirming that make is not in that image.

            Original answer text

            I checked, and the image haipengzhang/merchant_score_project does infact have have the make command in the path /usr/bin/make, and it is executable. The user in the image is root, and I am able to start the make command just fine.

            There is a little problem with your docker run command, but I do not think that it is related to the issue:

            You should not preceed the $(pwd) command with a / in the volume mapping. Try this instead:

            Compiling a multiple sheet Excel Spreadsheet into pycel
            Asked 2020-May-05 at 09:06

            TL;DR - trying to compile this multi-sheet Pycel tests/fixture spreadsheet (I'm particularly interested in capturing inter-sheet dependencies) using into Python code using Pycel

            The Problem

            The helpful Pycel example in the example/example.py in the Pycel repository runs perfectly and produces a handy .gexf graph, however, I can't work out how to compile a multi-sheet Spreadsheet (in my use case there is terrifying inter-sheet dependencies!) using Pycel.

            @Stephen Rauch mentioned that "Pycel does really deal with sheets. It works with cells. Those cells can come from any sheet in the workbook" in this Stackoverflow discussion, however, I couldn't find any detail on this in the Pycel repo or in prior questions.

            What I tried

            I tried compiling the spreadsheet included in tests/fixtures/excelcompiler.xlsx as this is multi-sheet and it only seems to compile for Sheet1 as the resulting plot is empty (Sheet1 is empty).

            TL;DR

            Pycel compiles multi-sheet Excel spreadsheets easily. Pycel's function pycel.ExcelCompiler is lazy and so doesn't actually compile Excel into Python until explicitly asked to do so via excel.evaluate('Result!E16')} (i.e. evaluate some cell)
