Design clever algorithms that can uncover interesting structures and hidden relationships in unstructured, unlabeled data Key Features * Learn how to select the most suitable Python library to solve your problem * Compare k-Nearest Neighbor (k-NN) and non-parametric methods and decide when to use them * Delve into the applications of neural networks using real-world datasets Book Description Unsupervised learning is a useful and practical solution in situations where labeled data is not available. Applied Unsupervised Learning with Python guides you on the best practices for using unsupervised learning techniques in tandem with Python libraries and extracting meaningful information from unstructured data. The course begins by explaining how basic clustering works to find similar data points in a set. Once you are well versed with the k-means algorithm and how it operates, you’ll learn what dimensionality reduction is and where to apply it. As you progress, you’ll learn various neural network techniques and how they can improve your model. While studying the applications of unsupervised learning, you will also understand how to mine topics that are trending on Twitter and Facebook and build a news recommendation engine for users. You will complete the course by challenging yourself through various interesting activities such as performing a Market Basket Analysis and identifying relationships between different merchandises. By the end of this course, you will have the skills you need to confidently build your own models using Python. What you will learn * Understand the basics and importance of clustering * Build k-means, hierarchical, and DBSCAN clustering algorithms from scratch with built-in packages * Explore dimensionality reduction and its applications * Use scikit-learn (sklearn) to implement and analyse principal component analysis (PCA)on the Iris dataset * Employ Keras to build autoencoder models for the CIFAR-10 dataset * Apply the Apriori algorithm with machine learning extensions (Mlxtend) to study transaction data Who this book is for This course is designed for developers, data scientists, and machine learning enthusiasts who are interested in unsupervised learning. Some familiarity with Python programming along with basic knowledge of mathematical concepts including exponents, square roots, means, and medians will be beneficial.

De k?zben arról ábrándozik, milyen jó lenne nappal látni a világot! Csupán egyetlenegyszer… Addig nem nyugszik, míg egy ver?fényes napon a kívánsága váratlanul nem teljesül. Ekkor izgalmas kalandok sora veszi kezdetét, és nemcsak a kis szellem számára… A Kolibri Klasszikusok sorozatban a Torzonborz-t?rténetek után egy újabb Otfried Preussler meseh?s, a kis szellem válhat generációk kedvencévé.

TARGETS ARE LOCKED! Five short novels by five masters of military SF capture the excitement, and hell, of fantastic future war—on and off the battlefield. Stories of terrifying monsters, dangerous aliens and staggering cosmic dreadnaughts march alongside far-flung courtroom dramas and cautionary tales involving man and his devices. Michael A. Stackpole—The Star Tigers are commandeered by a powerful alien overseer on a covert mission to a world long abandoned by an ancient species. There, the ruins of a forgotten war will tip the balance of their war, unless the Star Tigers can prevent it. Sarah A. Hoyt—Lucius Dante Maximilian Keeva is a well-respected leader of the Usaian Revolution, but treason in the ranks can cost him everything that makes life worth living—unless he takes justice into his own hands and breaks every military regulation in its pursuit. Doug Dandridge—Faced with an enemy more than two hundred times her own size, Cinda Klerk has two options: hide, and let it destroy the planet she is supposed to protect, or find a way to even the odds and kill the enemy, even at the cost of her ship and crew. Eytan Kollin and Dani Kollin—As the Unincorporated War envelops the entire solar system, a father must come to the rescue of a daughter he never raised. But he'll have to convince her to save herself first. Kevin J. Anderson—In the war against an alien menace, Earth’s greatest military commanders risk themselves on the front lines, but with an escape hatch: If the situation goes terribly wrong, they can switch places with a safe soldier far from the battlefield. But the cannon-fodder volunteers don’t consider that such a good deal. Set your cross-hairs on the Target Zone.

Mr. Hungerton, her father, really was the most tactless person upon earth,—a fluffy, feathery, untidy cockatoo of a man, perfectly good-natured, but absolutely centered upon his own silly self. If anything could have driven me from Gladys, it would have been the thought of such a father-in-law. I am convinced that he really believed in his heart that I came round to the Chestnuts three days a week for the pleasure of his company, and very especially to hear his views upon bimetallism, a subject upon which he was by way of being an authority. For an hour or more that evening I listened to his monotonous chirrup about bad money driving out good, the token value of silver, the depreciation of the rupee, and the true standards of exchange. "Suppose," he cried with feeble violence, "that all the debts in the world were called up simultaneously, and immediate payment insisted upon,—what under our present conditions would happen then?" I gave the self-evident answer that I should be a ruined man, upon which he jumped from his chair, reproved me for my habitual levity, which made it impossible for him to discuss any reasonable subject in my presence, and bounced off out of the room to dress for a Masonic meeting. At last I was alone with Gladys, and the moment of Fate had come! All that evening I had felt like the soldier who awaits the signal which will send him on a forlorn hope; hope of victory and fear of repulse alternating in his mind. She sat with that proud, delicate profile of hers outlined against the red curtain. How beautiful she was! And yet how aloof! We had been friends, quite good friends; but never could I get beyond the same comradeship which I might have established with one of my fellow-reporters upon the Gazette,—perfectly frank, perfectly kindly, and perfectly unsexual. My instincts are all against a woman being too frank and at her ease with me. It is no compliment to a man. Where the real sex feeling begins, timidity and distrust are its companions, heritage from old wicked days when love and violence went often hand in hand. The bent head, the averted eye, the faltering voice, the wincing figure—these, and not the unshrinking gaze and frank reply, are the true signals of passion. Even in my short life I had learned as much as that—or had inherited it in that race memory which we call instinct. Gladys was full of every womanly quality. Some judged her to be cold and hard; but such a thought was treason. That delicately bronzed skin, almost oriental in its coloring, that raven hair, the large liquid eyes, the full but exquisite lips,—all the stigmata of passion were there. But I was sadly conscious that up to now I had never found the secret of drawing it forth. However, come what might, I should have done with suspense and bring matters to a head to-night. She could but refuse me, and better be a repulsed lover than an accepted brother. So far my thoughts had carried me, and I was about to break the long and uneasy silence, when two critical, dark eyes looked round at me, and the proud head was shaken in smiling reproof. "I have a presentiment that you are going to propose, Ned. I do wish you wouldn't; for things are so much nicer as they are." I drew my chair a little nearer. "Now, how did you know that I was going to propose?" I asked in genuine wonder."Don't women always know? Do you suppose any woman in the world was ever taken unawares? But—oh, Ned, our friendship has been so good and so pleasant! What a pity to spoil it! Don't you feel how splendid it is that a young man and a young woman should be able to talk face to face as we have talked?" "I don't know, Gladys. You see, I can talk face to face with—with the station-master." I can't imagine how that official came into the matter; but in he trotted, and set us both laughing. "That does not satisfy me in the least. I want my arms round you, and your head on my breast, and—oh, Gladys, I want——"
