p.42, Exercise 7a., first line, replace
``Present a 2-class classification example to illustrate that minimizing
mean squared error''
to:
``For a two-class classification problem, discuss whether minimizing the
Euclidean distance measure (p.36), averaged over all input data''
-- there is a corresponding error in the solutions manual mailed
to instructors before Sept.'97.
p.58, fifth and sixth lines from bottom (equation lines),
insert 2 before first left parenthesis.
p.96, ninth line, fifth word, replace ``are'' by ``is'';
tenth line from bottom, replace ``equating'' by ``setting''.
p.97, first line, replace ``derivative'' by ``derivatives'';
second paragraph, fourth line, replace ``The secant method, which'' by
``A simple method that'';
replace the equation after the second paragraph by
dE'(w)/dwj =~
E'(w0,w1, ..., wj+t, ..., wn)/t
(in this equation, `d' is used instead of the partial derivative symbol,
`t' is used instead of `tau',
and `=~' is used to mean ``approximately equals'').
Delete the sentence after next, ``By substitution...''.
p.125, Figure 4.13, to the right of the horizontal line,
change the subscript of ß from 2 to 0.
p.138, algorithm in Figure 4.25, in the equation
on the third line before the caption, replace
zk by zl
and `U union I' by `U'.
Same changes also on p.139, same equation in fifth line from top.
p.146: replace each
(xp - µi)2 by
(||xp - µi||)2,
and
(xi - µi)2 by
(||xi - µi||)2
p.147, Equation 4.21: multiply the right-hand-side
by a factor of 1/sigma2.
p.155, ex.3c: an extra pair of parentheses is needed in the right-hand-side:
it should read exp(-(d/c)2).
p.166, end of first line: under the square-root sign,
change the subscript of the summation sign to `k=1',
and the subscript of w to `i,k'.
p.176, lines 5-6: replace ``. In other words,'' by
``, e.g., ''
p.178, Fig. 5.12, Phase 2, item 2(c), second line:
replace vk*j and vk*l by vj,k*
p.179, equation in sixth line:
replace both occurrences of wj*l by vl,j*
p.196, first line (after figure): delete `then'
p.198, last line: replace `Lampinen (1993)' by `Lampinen and Oja (1992)'
p.201, lines 4-5:
replace `has a fixed number of neighbors' by
`belongs to some hyper-tetrahedron'
p.203, equation in fifth line from the bottom,
replace `w' (after the comma) by `W'
and replace
`(i - wj)2' by
`(||i - wj||)2';
in the next line, after `where ',
add `P(i) describes the probability distribution of
the input vectors, '
p.209, third line of second paragraph:
replace `inverse' by `pseudo-inverse'.
p.225, Example 6.3, the weight matrix Omega should have been calculated
in a different manner, using equation 6.11 (bottom of p.223),
instead of as shown.
p.263, ex.1b: replace `generalized inverse' by `pseudo-inverse'.
