# Errata in print edition

# Preface

**p.xvii:**“prerequesite” -> “prerequisite”

# Chapter 2

**p.12:**X-value should be X-value**p.17:**“see why this is rule is” should “see why this rule is”**p.26:**The grey dash-dot ROC curve should connect (0,0) to (0.3,1.0) instead of (0.2,1.0). Otherwise the curves will not have equal area.

# Chapter 3

**p.38:**The equality should be \langle w_{t+1}, x_i\rangle = \langle w_t, x_i\rangle + \|x_i\|^2\,. The printed version has a y_i in front of the \|x_i\|^2 term. This is incorrect.

# Chapter 5

**p.95:**The final equation on the page should be (X^T X+ \lambda I_d)^{-1} X^T = X^T (X X^T+ \lambda I_n)^{-1}\,. The printed version has X rather than X^T immediately following the equals sign.

# Chapter 6

**p.106:**Notation \hat\mu_Z^{(n)} not defined. This is the sample mean of n i.i.d. samples drawn from Z.**p.116:**We claim that all hyperplanes of small norm had low VC dimension. But the hyperplanes have to satisfy y w^T x \geq 1.

# Chapter 7

**p.126:**“structure linear maps” should be “structured linear maps”**p.129:**“If \epsilon_t=0 is sufficiently small” should be “If \epsilon_t is sufficiently small”**p.130:**“Jacobian matrix is the n\times m matrix” should be “m\times n matrix”**p.131:**\mathsf{D}_{z_{L}} z_L(v_L)= I should be \mathsf{D}_{z^{(L)}} z^{(L)}(v_L)**p.135:**P^TE Q^T should be PEQ**p.135:**E is not defined. It should be the error matrix E=A-B.

# Chapter 9

**p.179:**Some samples shown in the table are not consistent with the data-generating procedure. The rows 1 1 1 and 1 1 0 cannot occur.

# Chapter 11

**p.221:**\mathrm{Tr}(Q\Sigma) should be \mathrm{Tr}(M\Sigma)

# Chapter 12

**p.251:**V_\star(x) \in [0, (1-\gamma)^{-1}] should be V_\star(x) \in [0, 1]**p.252:**\gamma^k should be \gamma^{i-1}**p.257:**“eigenvalue greater than 0 if t > 0.02” should be “eigenvalue greater than 1 if t > 0.02”

# Chapter 14

**p.266:**there should be no double quote after “pd”**p.266:**“a eigenvalue” should be “an eigenvalue”**p.274:**\lambda_s should be in the denominator

# Bibliography

- Reference 131: “continous” should be ”continuous”
