preprocess is a C++ library typically used in Artificial Intelligence, Natural Language Processing applications. preprocess has no bugs, it has no vulnerabilities and it has low support. However preprocess has a Non-SPDX License. You can download it from GitHub.

Pipelines for preprocessing corpora. Paths are relative to the build directory. does all the tokenization and normalization for normal text that has already been extracted and sentence split. takes Gigaword XML files on stdin and outputs text with P tags intended to be used as input to the sentence splitter. Also removes or normalizes many ad-hoc parenthesized expressions like (UNDERLINE) and consecutive duplicate lines. is the Moses/Europarl sentence splitter with a bugfix to also split sentences separated by two spaces. preserves existing line breaks and introduces additional breaks when multiple sentences appear in the same line. This is useful when you want to use the target side of parallel corpora for language modeling. combines the unwrap and sentence split steps. deduplicates text at the line level.

            I tried with scikeras but I got errors because it doesn't accept not-numerical inputs (in our case the input is in str format). So I came back to the standard keras wrapper.

            The focal point here is that the model is not built correctly. The TextVectorization must be put inside the Sequential model like shown in the official documentation.

            Why does GCC remove the whitespace between the preprocessing tokens?
            Asked 2022-Feb-03 at 20:10

            Sample code:

            ANSWER

            Answered 2022-Jan-20 at 14:29

            This is a bug in GCC. C 2018 6.10.3.2 specifies behavior of the # operator. Paragraph 1 says “Each # preprocessing token in the replacement list for a function-like macro shall be followed by a parameter as the next preprocessing token in the replacement list.” We see this in the #x of #define STR_(x) #x.

            Paragraph 2 says:

            If, in the replacement list, a parameter is immediately preceded by a # preprocessing token, both are replaced by a single character string literal preprocessing token that contains the spelling of the preprocessing token sequence for the corresponding argument. Each occurrence of white space between the argument’s preprocessing tokens becomes a single space character in the character string literal. White space before the first preprocessing token and after the last preprocessing token composing the argument is deleted…

            The X(Y,Y) macro invocation must have resulted in the tokens Y and Y, and we see in #define X(x,y) x y that they would have white space between them.

            White-space in a macro replacement list is significant, per 6.10.3 1, which says:

            Two replacement lists are identical if and only if the preprocessing tokens in both have the same number, ordering, spelling, and white-space separation, where all white-space separations are considered identical.

            Thus, in #define X(x,y) x y, the replacement list should not be considered to be just the two tokens x and y, with white space disregarded. The replacement list is x, white space, and y.

            Further, when the macro is replaced, it is replaced by the replacement list (and hence includes white space), not merely by the tokens in the replacement list, per 6.10.3 10:

            … Each subsequent instance of the function-like macro name followed by a ( as the next preprocessing token introduces the sequence of preprocessing tokens that is replaced by the replacement list in the definition (an invocation of the macro)… Within the sequence of preprocessing tokens making up an invocation of a function-like macro, new-line is considered a normal white-space character.

            ANSWER

            Answered 2022-Jan-02 at 14:10

            You can use a 2D FFT to find the general direction in which the crop is aligned (as proposed by mozway in the comments). The idea is that the general direction can be easily extracted from centred beaming rays appearing in the magnitude spectrum when the input contains many lines in the same direction. You can find more information about how it works in this previous post. It works directly with the input image, but it is better to apply the Gaussian + Canny filters.

            Here is the interesting part of the magnitude spectrum of the filtered gray image:

            The main beaming ray can be easily seen. You can extract its angle by iterating over many lines with an increasing angle and sum the magnitude values on each line as in the following figure:

            Here is the magnitude sum of each line plotted against the angle (in radian) of the line:

            Based on that, you just need to find the angle that maximize the computed sum.

            Here is the resulting code:

            Determine whether the Columns of a Dataset are invariant under any given Scikit-Learn Transformer
            Asked 2021-Dec-19 at 08:42

            Given an sklearn tranformer t, is there a way to determine whether t changes columns/column order of any given input dataset X, without applying it to the data?

            For example with t = sklearn.preprocessing.StandardScaler there is a 1-to-1 mapping between the columns of X and t.transform(X), namely X[:, i] -> t.transform(X)[:, i], whereas this is obviously not the case for sklearn.decomposition.PCA.

            A corollary of that would be: Can we know, how the columns of the input will change by applying t, e.g. which columns an already fitted sklearn.feature_selection.SelectKBest chooses.

            I am not looking for solutions to specific transformers, but a solution applicable to all or at least a wide selection of transformers.

            Feel free to implement your own Pipeline class or wrapper if necessary.

            using OneHotEncoder is not the way to go here, it's better to extract the features from the column time as separate features like year, month, day, hour, minutes etc... and give these columns as input to your model.
