-
- 5.1 _B_u_g__F_i_x_e_s__i_n__M_i_n_e_S_e_t__2_._5
-
- 5.1.1 _B_u_g__F_i_x_e_s__i_n__t_h_e__T_o_o_l__M_a_n_a_g_e_r
-
- +o If you created a new column using an expression and
- that expression caused an error for Datamove, deleting
- the column using the "remove column" button did not
- work. This problem no longer occurs.
-
- +o When working with data files containing arrays, the
- Tool Manager let you change the type of the array using
- the Change Types dialog. This caused an error for
- Datamove. The Tool Manager no longer allows this
- change.
-
- +o During the "Show Original Data" aspect of drill-
- through, if the current Tool Manager is connected to
- the necessary server, it uses that connection to
- retrieve the data. If the drill-through required a
- different server, or server login, it creates a new
- connection. If the Tool Manager was connected to the
- same server but a different DBMS than that used in the
- drill-through, it was possible to kill the server
- process currently in use by the Tool Manager and void
- the current transformation history. MineSet 2.5 now
- informs the user and gives them the choice between
- completing the drill-through and losing the history, or
- cancelling the drill-through and keeping the history.
-
- +o If you did a drill-through, and the currently running
- Tool Manager was iconified, it did not raise itself.
- It now correctly returns from a minimized state.
-
- +o Trying to change the types of columns used for
- associations would cause errors when running
- AssocConvert. Similarly, adding new columns of string
- type would cause errors when running AssocConvert.
- These problems have been fixed.
-
- 5.1.2 _B_u_g__F_i_x_e_s__i_n__t_h_e__D_a_t_a__M_o_v_e_r
-
- +o The ASCII file format produced by the Data Mover used
- tabs to delimit the boundaries between attribute
- values, and newlines to delimit records. If a database
- table contained attribute values with embedded tabs or
- newlines, the file produced by the Data Mover was not
- readable by the Data Mover or any of the MineSet tools.
- The Data Mover no longer produces embedded tab or
- newline characters.

- 5.1.3 _B_u_g__F_i_x_e_s__i_n__t_h_e__R_e_c_o_r_d__V_i_e_w_e_r
-
- +o Attempting to expand the last column to the right did
- not always work correctly. There are now no known
- problems with resizing columns.
-
- 5.1.4 _B_u_g _F_i_x_e_s _i_n _I_n_d_u_c_e_r_s, _C_l_a_s_s_i_f_i_e_r_s _a_n_d _C_o_l_u_m_n
- _I_m_p_o_r_t_a_n_c_e
-
- +o When a classifier was applied (apply-classifier from
- Tool Manager), the resulting column was always a
- string, even if the original label column was of
- another type. Columns are now correctly typed.
-
- 5.1.5 _B_u_g__F_i_x_e_s__i_n__t_h_e__T_r_e_e__V_i_s_u_a_l_i_z_e_r
-
- +o When the decision tree generated a view for the Tree
- Visualizer, sometimes the colors used for mapping the
- different bars was similar to the colors used for
- mapping purity, even though there was no relationship
- between them. The correct colors are now used.
-
- 5.1.6 _B_u_g__F_i_x_e_s__i_n__t_h_e__M_a_p__V_i_s_u_a_l_i_z_e_r
-
- +o The Map Visualizer no longer uses the ToolTalk library
- to implement inter-tool synchronization of the
- Animation Control Panel. ToolTalk was the cause of an
- infrequent silent hang at Mapviz startup time.
-
- 5.2 _B_u_g__F_i_x_e_s__i_n__M_i_n_e_S_e_t__2_._0_1

- 5.2.1 _B_u_g__F_i_x_e_s__i_n__t_h_e__T_o_o_l__M_a_n_a_g_e_r
-
- +o Drill-through on binned attributes with many (>1000)
- bins could cause the Tool Manager to crash. This has
- been fixed.
-
- +o In some cases, if a DataMove server was killed by
- another datamove, the Tool Manager connected to the
- killed DataMove sometimes failed with a SIGPIPE
- exception, and more rarely with a core dump. These
- problems have been fixed.
-
- +o In some rare cases, using the edit history dialog (but
- making no changes) when the data source is a client
- file could cause spurious error messages and core
- dumps. This has been fixed.
-
- +o In the dialog for opening data files, entering a "/"
- after the file name could cause a core dump. This has
- been fixed.

-
-
- +o When running associations, if the table contains
- numeric columns that have been converted to strings,
- spurious error messages would be produced in version
- 2.0. This has been fixed.
-
- +o In some cases the preview column names would become
- corrupted in the SQL Query dialog. This problem has
- been fixed.
-
- +o If one added a new column, then changed the type,
- drill-through on that column would fail. This has been
- fixed.
-
- +o The "Reopen" menu option would incorrectly change the
- name of the current session. This has been fixed.
-
- +o When binning a column twice, the resulting two binned
- columns would be given the same name. Now they are
- given different names.
-
- +o Automatic binning (used for automatic slider generation
- or splatviz) would fail if the column being binned only
- had one value. This case now works correctly.
-
- +o Setting the legends for RuleViz did not work correctly
- in 2.0. This has been fixed in 2.0.1.
-
- +o A few bugs and performance issues related to the loss
- matrix have been fixed in version 2.0.1. In version
- 2.0 when the user attempted to edit a loss matrix or
- display a lift curve, discrete values for all
- attributes were fetched from the server and cached.
- For large datasets, fetching all discrete values was
- very slow. In version 2.0.1, only values for the
- selected discrete label are fetched and cached. This
- new method speeds up fetch time considerably and
- improves the management of loss matrix and lift curve
- label value persistence.
-
- +o There was a persistence bug with bins created using
- automatic thresholds: When editing a bin loaded from a
- .mineset file the "Use Weight" toggle would always be
- set. To fix this bug it was necessary to always turn
- the toggle OFF when loading a .mineset file created by
- versions prior to the final 2.01 release (including all
- beta versions of 2.01.) Hence beware: when loading an
- old .mineset file where a weight had been set for
- automatic binning, you must reset the weight manually
- and save again.

-
- +o The Evidence Classifier would not handle weighted
- records correctly if the Laplace correction was turned
- on. This has been fixed.
-
- +o The Option Tree Inducer would not reduce the number of
- options below 2 if the number of options at any level
- was exactly 2. This has been fixed.
-
- +o The Decision Tree Inducer, and the Option Tree Inducer
- could fail (fatal error from MIndUtil) if the user
- attempted to build a tree using a table containing
- columns that had the empty string ("") as a value
- somewhere. This has been fixed.

- 5.3 _B_u_g__F_i_x_e_s__i_n__M_i_n_e_S_e_t__2_._0
-
- 5.3.1 _G_e_n_e_r_a_l__B_u_g__F_i_x_e_s
-
- +o The precedence for expressions involving &, |, and ^
- was wrong in all tools that used expressions. It now
- correctly follows the C semantics.
-
- 5.3.2 _B_u_g__F_i_x_e_s__i_n__t_h_e__T_r_e_e__V_i_s_u_a_l_i_z_e_r
-
- +o In the previous release, bars would sometimes grow when
- highlighted. This has been fixed.
-
- +o Spotlights now always come from the same angle; they no
- longer appear horizontal when deep in the tree.
-
- +o Marks will now work correctly when binning has been
- used.
-
- 5.3.3 _B_u_g__F_i_x_e_s__i_n__t_h_e__M_a_p__V_i_s_u_a_l_i_z_e_r
-
- +o The "Pointer is over" message will no longer disappear
- if it is too wide for the window.
-
- 5.3.4 _B_u_g__F_i_x_e_s__i_n__t_h_e__S_c_a_t_t_e_r__V_i_s_u_a_l_i_z_e_r
-
- +o The "Pointer is over" message will no longer disappear
- if it is too wide for the window.
-
- 5.3.5 _B_u_g__F_i_x_e_s__i_n__t_h_e__R_u_l_e__V_i_s_u_a_l_i_z_e_r
-
- +o The "Pointer is over" message will no longer disappear
- if it is too wide for the window.
