Errata for An Introduction to Neural Networks
These are the typos that I have noticed. There are probably more.
If you find something you think may be an error, please let me know.
Chapter 7
-
p. 187 (equation at top): -(1/2) / ((x -zi)2
/ sigma2)
should be -(1/2) * ((x-
zi)2 / sigma2)
-
p. 195 (line 2 from bottom): "f at the output" should
be "g at the output"
Chapter 8
-
p. 220 (line 15 from bottom): "referred to as {yk}"
should be "referred to as yk"
-
p. 220 (line 5 from bottom): "-c subtracted"
should be "c subtracted"
-
p. 226 (equation at top): all four absolute value terms should
be squared (e.g., | w -
wk | should
be | w - wk
| 2
)
-
p. 226 (equation in middle of page): dk+1>
2 [wk, yi']
-
[yi',yi']
should be dk+1>
2 [w, yi']
-
[yi',yi']
-
p. 226 (middle of page): "maximum value of length, which we call
m"
should be "maximum value of length squared,
which we call m"
Chapter 9
-
p. 245 (equation at top): f(w1)
- f(w0) should be f(s1)
- f(s0)
-
p. 247 (equation at bottom): f [1] should be
f
[0]
-
p. 261 (middle of page): g[i] = f [wf
g, f ] should be g[i]
= f ([wf g,
f
])
-
p. 262 (equation at top): f '([wf
g, f ]) should be f
'([wf
g,
f ])
-
p. 262 (line 5 from bottom): f '(g[i])
should be f '([wf
g, f ])
-
p. 262 (equation at bottom): f [wgh,
g
] should be f ([wgh,
g])
-
p. 263 (top line): k should be k
-
p. 263 (line 5 from top): "the definition of delta[k]"
should be "the negative of the definition
of delta[k]"
-
p. 263 (equation in middle of page): f
'[wf g, f ]
should be f '([wf
g, f ])
-
p. 266 (middle of page): "201 input units" should be
"203 input units"
