    Changed the behavior of binarize_label

commit adb23e3c537d9c2d2ce36c27700a85ff6852964b
Author: Sotaro Sugimoto <sotaro.sugim...@gmail.com>

    Added Kernelized Passive-Aggressive Algorithm for Classification Problems.

commit bc228746c7f7b1abc0f6e7846d52ca1edad7fea7
Author: Sotaro Sugimoto <sotaro.sugim...@gmail.com>
Date:   2016-04-12T09:14:45Z

    Bug fixes
    Also newly added KernelizedPassiveAggressiveUDTFTest based on 
PassiveAggressiveUDTFTest, but tests are not done for newly added functionality.

commit adac4e5bd0d89cc8c68768c9fb5bc1765bc3fac3
Author: Sotaro Sugimoto <sotaro.sugim...@gmail.com>
Date:   2016-04-14T09:51:14Z

    Test for news20 written; some bugs fixed.
    Bug still occurs for news20-small.binary where the loss does not match 
between udtf and udtfPKI starting at sample 51, where the label switches from 
all -1s to all +1s. Also, news20.binary not included due to large filesize.

commit 6072a2ae7f1d0f8a0023dbe428a38c201386e38e

    Refactored to use Bitset for support vector indices

commit ecf4f3ab55ccdbe7c57bcd21b292e485465fb566
Author: myui <yuin...@gmail.com>
Date:   2016-04-14T11:55:49Z

    Changed resource location of unit tests

commit 3994cc7bb706e0b073278176eee6a1a5b78bebf6
Author: Sotaro Sugimoto <sotaro.sugim...@gmail.com>
Date:   2016-04-15T06:17:18Z

    Both normal and PKI versions of KPA now learn identically.
    Note that testTime was added to see how much faster PKI is, but it appears 
that PKI is actually slower than normal KPA for non-sparse support vectors, 
since PKI must go through the work of finding all matching support vectors, 
which is O(number of support vectors) for a completely full match.

commit 31d981bd0082d4d5c40d7eb536f47f70455a3c52
Author: Sotaro Sugimoto <sotaro.sugim...@gmail.com>
Date:   2016-04-15T09:38:49Z

    Fixed incorrect alpha calculation/storage.
    Also fixed tests and asserts to match correct alpha calculations.

commit e2812fd035f51877167f0c77aff397fa45be0bef

    Added FloatArrayList.
    Also changed alpha from DoubleArrayList to FloatArrayList.

    Added kernel expansion option (untested)

commit 4716b34ad5038761d18e422833d9334140dd0908
Author: Sotaro Sugimoto <sotaro.sugim...@gmail.com>
Date:   2016-04-21T03:34:26Z

    Tests for KPA added.
    Note that kernel splitting (in KernelExpansionKPA) is incomplete.

commit f986803901824ad831c7c8a2504c26797d765f23
Author: Sotaro Sugimoto <sotaro.sugim...@gmail.com>
Date:   2016-04-26T04:21:22Z

    Kernel Expansion complete with tests.
    Also removed Kernel Splitting (probably uses too much memory).
