Great Book.......2007-03-20
A great tool for Harmonic Analysis. The book is really well written, a most read for any one who is interested in the area of wavelets, S.P. or harmonic analysis.
The most universal treatment of the subject.......2005-06-08
I say universal because this book would appeal to engineers, computer scientists, and mathematicians alike. Mallat was particularly successful to present the topic in a sufficiently rigorous way but without losing sight of the practical and more intuitive side. The presentation comprises the mathematical and the signal processing viewpoints simultaneously. The wavelet field is very vast by now with several subfields. In this respect, Mallat made a great selection of topics in this book. There is a chapter on estimation which offers great review material and pretty much the state-of-the art on signal estimation over a wavelet basis. The chapter on approximation is particularly useful for those who are not well versed in approximation theory and thus are unable to understand other treatments. If you're interested in learning wavelet theory to solve practical problems such as image compression, signal estimation, etc, this is the book to have.
The worst textbook I have ever seen.......2004-02-12
I just finished Chapter 3 of this book, but I have had enough of it. Conceptions about Fourier Transform are not clear at all. And the most unbearable thing is that, there are many printing errors which may lead to misunderstanding.
Algorithms and much more!.......2002-07-10
The subject of wavelets has many facets, --infinite in all directions;-- some of the more exciting sides of the subject
are algorithmic, and the underlying mathematical principles are both simple and powerful. Stephane Mallat's great, and readable, book, in both of its editions, brings
this out wonderfully!
A bold approach to wavelet transforms that simplifies.......2002-04-24
This is an outstanding tour through the field of wavelet decompositions of both continuous and discrete signals. It employs the formalism of Hilbert space, instead of linear algebra. This is important because the power of this formalism yields insights into the subject matter that are practically impossible in linear algebra. The formalized approach allows a wide variety of subjects to be placed on a common basis (no pun intended). For example, the transition of the treatment of the Fourier transform into Hilbert space, brings to bear the powerful guns of that space (such guns as inner product and completeness), and allows for a truly elegant proof of the Parseval and Plancherel formulas.
Parseval's theorem, simply stated, is that the inner products in Hilbert space are conserved by the Fourier transform. How simple. Linear algebra approaches cannot hope to make things this simple.
Proof of the General Sampling Theorem is equally elegant; it is shown that the projection of the function to be decomposed onto a basis function gives the discrete spectral coefficient.
Readers will also enjoy the treatment of windowed Fourier transforms and frames.
I should add a note about the style of the treatise. This treatise is not ordinary. It consistently uses very precise and carefully defined symbology. Contrary to popular belief, this makes the text easier to read, not more difficult. Once the reader understands the symbol set being used (they are all defined in the front of the text), even the proofs are tractable. Yes, I said proofs. That is another aspect of the text. There are proofs embedded in the text, without loss of continuity or clarity. Proofs are necessary to a good understanding of the subject matter. The formalism of theorems, lemmas and propositions makes the conclusions understandable, because the theorems, lemmas and propositions supporting the conclusions are identifiable.
I applaud the author for his approach and recommend that other text book writers use the same approach.
Book Description
Paradise of the Blind is an exquisite portrait of three Vietnamese women struggling to survive in a society where subservience to men is expected and Communist corruption crushes every dream. Through the eyes of Hang, a young woman in her twenties who has grown up amidst the slums and intermittent beauty of Hanoi, we come to know the tragedy of her family as land reform rips apart their village. When her uncle Chinh's political loyalties replace family devotion, Hang is torn between her mother's appalling self–sacrifice and the bitterness of her aunt who can avenge but not forgive. Only by freeing herself from the past will Hang be able to find dignity –– and a future.

Full of atmosphere, with a taste of the sacred.......2007-10-05
a very good book, worth reading for anyone, but especially if you're interested in Vietnam, Vietnamese culture, communism, or southeast asian cuisine.
Fragrant Herbs and Bitter Truths.......2006-09-15
This is a fine novel in many ways, at once probing the fissures and scars of life in modern Vietnam in an uncompromising manner while telling a tragic tale of family conflict and broken dreams. The descriptions of everyday life are rich and detailed in ways that move the story along, and the author has framed the story well by presenting much of it as flashbacks and flashbacks within flashbacks, which enables her to compellingly uncover the complex snarl of events and episodes entangled with Vietnam's troubled history as all of this affects the present.
In terms of pages this is a novel of modest length, but so much is going on. There is a definite political edge to it, a sharp critique of the absurdities, deprivations, and hypocrisies of life under a Communist regime by a former true believer. But that's only the beginning. The polarization of urban and rural life is also a major theme, as is the complicated links and disjunctures between generations. Even geopolitics as it affects individuals comes into play, and all of this in a way that seems perfectly natural in this well-told tale.
Still, the characters, while generally convincing, are sometimes just short of three-dimensional. Hang's Uncle Chinh is always despicable, her Aunt Tam is always strong and vengeful, and so on. Not quite caricatures, but a bit too close nevertheless. And while the role of food is important in this novel in many interesting ways, signifying bounty and comfort but also manipulation and power, still sometimes the grocery list gets a bit long. All of which just means that the novel is excellent but not perfect. The translators have also provided an introduction, a glossary, and a note on the author that helpfully and unobtrusively give the reader the right amount of context to appreciate this fine work.
An Uncomprising Critique of "Revolutionary" Vietnam.......2006-08-29
A short response to any book by Duong Thu Huong is a good deal like a short response to the Bible--it will be lacking. This is especially the case with Huong's 1988 work Paradise of the Blind, the story of a young Hanoi woman, Hang, forced to give up her university studies and work in the Soviet Union in order to support her mother. This is only half the story though. Hang reached adulthood after the heroic period of the twentieth century in Vietnam, namely the wars for independence and reunification, as well as the revolution. These events led to colossally momentous experiences in the lives of Hang's family--her mother and aunt whom she loves and the uncle she hates--so profoundly shaping were the experiences of these times that there consequences for Hang's family have nearly as deep consequences for her own life. Ultimately the only way that Hang is able to escape the chains bind her family members to the past is by abandoning her connection to the it.
Hang's troubles actually began a decade before she was born when Uncle Chinh returned triumphant from the war against the French to introduce land redistribution to his own and her mother's village in the middle 1950's. The approach Chinh took to land reform essentially ensured that he was going to be less than beloved by any person in the village--finding the most depraved and degraded of the village's lumpen proletariat and elevating them to the status of rural working class heroes. The paternal side of Hang's family has their property ruthlessly expropriated and her father is forced into internal exile. Chinh does not just acquiesce to their impoverishment and humiliation, but his own belief in the socialist millennium being just around the corner impels him, quite happily, to fanatically push for it and treat his sister harshly for continuing to even care about dispossessed husband and in laws. Chinh thus violates loyalty to kin in order to serve his own ideological pretensions and a poorly articulated form of class solidarity. At the novel's close when we see him waiting hand and foot on smugglers half of his age in order to better his material circumstances, it is truly pitiful, but is justice through history's cunning--one that was not likely to have been lost on the government authority that decided to withdraw the book from circulation.
Considering the pain he has caused, Chinh is not worthy of pity, but it is hard to argue that his situation is not pitiful. Hang's Aunt Tam is the surviving victim of Chinh's fanaticism, but she is not a character that could easily be described as pitiful, though she is worthy of pity in a way Chinh simply is not capable of being. Kept warm at night by the hate she has for Chinh and the contempt she holds all Communists in, this fanatically hardworking capitalist has grown absurdly rich by Vietnamese standards, without having to employ another person; thus making her a walking and talking reminder that not every rich person is rich by dint of exploiting the labor of the poor. Where Chinh is a fanatic who ultimately gives in to the system's endemic corruption, making a hypocrite out of himself, Tam is perfectly willing to use her money to subvert the system when it is convenient to do so and she makes no bones about where her power and influence come from and where her loyalties lie. Her riches and the influence that she wields are the product of an absolutely implacable sense of indignation at the injustices her own family suffered at the hands of the Communists in general and Chinh in particular.
Once Hang is old enough to form an opinion of her Uncle it is overwhelmingly negative and overtly hostile, though she is not capable of despising her uncle with the intensity that her Aunt--a Herculean task even without trying to grow richer with every passing day purely through hard labor. Que, Hang's mother, would seem to have as much justification to despise Chinh as Tam, because he certainly ruined her marriage through his ideological pretensions and career considerations. Instead she slavishly and thanklessly provides for his and his family's needs to her own and Hang's physical detriments. Que's dedication to Chinh's well being is repellant to Hang for the same reasons that it is repellant to most American readers; is a moral weakling incapable of admitting he performed a massive injustice. What makes it truly disgraceful, in Hang's eyes, is that Que's work is an attempt to maintain a link to a past that did nothing but bring pain to herself, her aunt, and Hang during her childhood where she was deprived of a father. Familial piety is an honorable and comprehensible value to Hang, one which she is filled with enough of to send her abroad to support her mother after she is crippled, and indefinitely put her own ambitions on hold; but it is so distorted and so pathetic in Que, that it invites at best pity and at worst contempt.
The fanaticisms of ideology, wealth and revenge, and continuity with a bucolic past that is a part of the three adults who had the greatest influence Hang could have consumed her had she not decisively broken with that past. Hang's own liberation will come only with that unforgiving war of attrition that finally kills all passions of memory and replaces it with largely dispassionate and impersonal history. The difficulties and Hang's life were almost wholly the cause of her kin living life's passions at extremes that could do nothing but cause her further distress were she to try to honor any of the values that they found to be so important--even gave their lives meaning. All of their lives have tragic elements to them, and it is precisely for that reason that Hang refuses to be imprisoned by their collective pasts. That past has to be down graded in importance if she is to be free to make a future for herself.
Universal and specific.......2006-01-26
I bought this book after hearing an interview with the author on National Public Radio. She has an antagonistic attitude toward the regime, which, for reasons of its own, tolerates her. Duong expresses negativity toward Vietnamese communism mainly through her depiction of the narrator's uncle, a petty, dogmatic, narrow-minded cadre who brutalizes the narrator's angelic father. The preferability of capitalism is epitomized by the narrator's aunt, a wise, conscientious small landholder who overcomes adversity. The young female narrator would earn the sympathy of anybody under any system that shatters dreams and stifles opportunity. A good read, but be wary of the author's agenda.
A not often seen picture of Vietnam.......2005-10-28
This atmospheric novel offers a well-written story that is rich in detail. It portrays the intricacy of Vietnamese culture in a way that makes one think and feel. We can learn (and as a result understand) so much more about a culture from its literature than we can from what is printed in newspapers. Unfortunately, most conclusions about Vietnam stem from what was reported during the 1960s and 1970s. This novel does much for increasing our understanding of a complicated country.
