Mistakes do happen! If you spot an error in the book, please let the authors know. We will endeavor to keep an up-to-date and searchable list of known errata on this page.
| Page | Location | Description |
|---|---|---|
| 438 | Lines 20-21 | Should read "... (Duckham & Sharp, 2005)" instead of "... Duckham & Sharp (2005)" |
| 368 | Table 9.4 | Leftmost column heading should read "Relation" instead of "rowcolorLightestPrimaryRelation" |
| 377 | Line 28 | Should read "... measures the data correctly classified" instead of "... measures of the data correctly classified" |
| 396 | Line 11 | Should read "CNNs can increase both computational and statistical efficiency ..." instead of "CNNs achieve increase both computational and statistical efficiency ..." |
| 234 | Figure 6.15 | The labels "SE" and "SW" are transposed in the figure. The branches should read (left to right): NW, NE, SW, SE. |
| 6 | Box 1.2 | Should read "... more than 1.5 TB ..." instead of "... more that 1.5 TB ..." |
| 15 | Line 14 | Should read "... capability to run predictive ..." instead of "... capability run predictive ..." |
| 32 | Line 22 | Should read "... as there are books in the area ..." instead of "... as there books in the area ..." |
| 96 | Closure definition | Should read "... the closure of X is the union of X with the set of all its near points." instead of "... .. the closure of X is the union of S with the set of all its near points." |
| 104 | 4th line from bottom of the page | Should read "... point-set topology leads directly to formal definitions of boundary, interior, and closure." instead of "... point-set topology leads directly to formal of boundary, interior, and closure." |
Page 234 (and others related to the quad tree figures) has some contradictory information. The apparent assumption is that the quadrants are named by the normal cartesian quadrant notation as NW, NE, SE, SW (which proceed in a “clockwise” order), and the colors corresponding to black (non-leaf; further division needed), white (no data; no division), and pink (leaf; data; no division) (sorry for the rudimentary explanation). However, the “clockwise” ordering of the colors in the grid doesn’t match the labels in the tree itself. In the level 1 branch, SE should be pink and SW should be white (but they are listed oppositely). Should they proceed clockwise, or left-to-right, top-to-bottom? If the tree itself is correctly colored, then it seems the correct order would be NW, NE, SW, SE (rather than SE, SW).
Same comments elsewhere in the quadtree discussion.
Thanks for this. The ordering should be consistently the “z” order throughout: NW, NE SW, SE (i.e., left-to-right and top-to-bottom, never clockwise). But thanks to your comment I can see there is an error in Figure 6.15 p234, where the “SE” and “SW” labels are incorrectly positioned; they should be switched around. My sincere apologies for that, you’ve spotted an error I’ll add to this list.
With that change to Figure 6.15, always Z-order, can you see any other problems? I think it should all then be consistent, with apologies.
