Hi Sarthak,

Thanks for submitting your proposal. Proposals are frozen at this point.
Right now we're completing ranking and waiting for Google to assign slots.

Best regards,
    Dmitry

Hello Dmitry,

As you know I did submit the proposal on the GSoC portal but there has been no discussion of any kind.
I also completed my GSoC task(fixed the bug) on time.

So I request you to kindly review my proposal once and provide your feedback. I will make the necessary changes or if you want to change the idea and implementation we can work on that also. I am really interested in applying for the program and contibuting to gdal.

Regards,
Sarthak

        Hi Sarthak,

        Thank you for you note, but I already wrote:

        >    Don't wait for anybody with proposal. The new GSoC site
        is right place to discuss proposals.

        So I expected to see and comment, if needed, your proposal on
        this site. Let me remind you the site -
        https://summerofcode.withgoogle.com/

        Best regards,
             Dmitry

            Hello Dmitry,

            I fixed the bug (I guess).
            Now coming to my proposal for GSoC, So I was thinking of
            working on project #4 *Auto-detection of EPSG codes from
            incomplete WKT.*

            What I understood from the project is that we need to
            predict the EPSG code of certain files on the basis of
            some attributes which are available in the file.

            The attributes can be extracted from the file for which I
            read this
            <http://www.gdal.org/osr_tutorial.html#querying_coordinate_system>.

            Now to solve this problem I thought a lot of methods but
            I think the best way to solve it will be using machine
            learning.

            The way ML will handle this problem is as follows-

             1. We need to find the EPSG code for a file (testing data)
             2. We have a file with some attributes
                (projections,datum,etc ).
             3. We need to the guess the best suitable class for that
                file(EPSG)
             4. Also, we have many files for which we know the
                attributes and the corresponding class (training data).

            This problem is now translated into an ML problem which
            can be solved using the following models-

            1. Bayesian Stastics
            <https://en.wikipedia.org/wiki/Posterior_probability>

                where,
                posteriror probability = probability of this file
                have EPSG code 'a'.
                prior probability = probability of occurence of EPSG
                code 'a'.

                likelihood probablity = cases where we saw such
                attributes when the EPSG code is 'a'.


            2. or we can use a simple knn where k is the number of
            possible EPSG code and the dimension of the feature
            vector is the number of possible attributes. we need to
            the find a valid and promising weight function).


            3. We can use multi-class SVM.

            4. any other suggestion from the community regarding the
            possible choice of the algo.

            I am thinking of actually implementing all these algo(may
            add algo in future depending upon the suggestion) and
            select the algo which gives the best performance among
            all of them.

            Please provide me feedback on my proposal and suggestion
            if I can add/change anything.
            And since very less time is left in the deadline, I would
            like to convert it into proposal ASAP with your help.

            Regards,
            Sarthak
