I'm struggling with math while I'm reading Machine learning: A probabilistic perspective like I'm confused about quantiles, inverse cdf etc. Could you recommend me a book that I should read first? The best STEM book I've ever read. Goes into great depth without sacrificing any ease of comprehension. Few recourses, in any subject, can provide both.

Today we have some very good AI/ML posts. First, Pete Warden tells us how to break into machine learning. It is some very practical advice on how to get started. David Lettier shows us how to develop K-Means from scratch. Lastly, on An Uncommon Lab we get to see how Kalman Filters work.

A couple have been told to restrain their cat or face having their mail deliveries suspended. Matthew Sampson was notified by Royal Mail last week of a "potential hazard" at his home in South Gloucestershire which was "affecting deliveries". According to Royal Mail, Bella the cat is a "threat" to staff and has been putting "fingers at risk of injury". But owner Matthew Sampson, said he was "shocked" by the notice as he has "never seen her get aggressive". In the letter, Royal Mail states it has been "experiencing difficulties in delivering mail" to Mr Sampson's address in Patchway "because of the actions of a cat". It said the couple's postman had reported that when he pushes mail through their letterbox their cat "snatches the mail and put his fingers at risk of injury".

Not surprisingly, the Guild isn't happy with the Supreme Court's choice -- it calls this a "colossal loss" and insists that the appeals court was "blinded" by Google's attempt to portray itself as rescuing lost books for the public good. The statements are a bit melodramatic (many of these titles are unlikely to return to print before they reach the public domain), but they do point out that the concerns over digitizing books aren't quite over. Although Google appears to have walked a fine line, the worry is that other outfits might not be quite so scrupulous.

The Authors Guild and several individual writers have argued that the project, known as Google Books, illegally deprives them of revenue. The high court left in place an October 2015 ruling by the 2nd U.S. Circuit Court of Appeals in New York in favor of Google. A unanimous three-judge appeals court panel said the case "tests the boundaries of fair use," but found Google's practices were ultimately allowed under the law. The individual plaintiffs who filed the proposed class action against Google included former New York Yankees pitcher Jim Bouton, who wrote the acclaimed memoir "Ball Four." Several prominent writers, including novelist and poet Margaret Atwood and lyricist and composer Stephen Sondheim, signed on to a friend-of-the-court brief backing the Authors Guild.

Fair use also allows for people to transform the original content into a new type of work, and that transformation of the printed books was part of Google's argument in this case. The group wanted the Supreme Court to "recognize Google's seizure of property as a serious threat to writers and their livelihoods, one which will affect the depth, resilience, and vitality of our intellectual culture," the Authors Guild said on a webpage detailing the case. The Supreme Court decision gave authors a "colossal loss," Authors Guild President Roxana Robinson said in a statement. Google Books project may lead to a short-term public benefit, but it will come at the expense of the future vitality of U.S. culture, Robinson added. "The denial of review is further proof that we're witnessing a vast redistribution of wealth from the creative sector to the tech sector, not only with books, but across the spectrum of the arts," she said.

A lot of people would struggle to get through their daily lives without the help of glasses, but for most, they help make everything they are looking at slightly clearer. But for one man, a new pair glasses is doing much more than that, allowing him to read for the first time in 20 years. Luke Hines was left blind in one eye and with only three per cent vision in the other after an operation to remove a childhood brain tumour in 1997.

He was unable to attend school, has not found work because of his condition and has spent years feeling isolated.

TROISDORF, Germany (Reuters) - Germany's Deutsche Post is testing robots that could help postal workers cope with increasing numbers of parcels on their delivery rounds, a company manager said on Thursday. The volume of parcels being delivered by Deutsche Post in Germany is rising steadily as more and more Germans buy goods online from retailers such as Amazon.com That is making up for declining letter volumes, but posing problems due to the larger size of items involved. "Robots could be used in deliveries in three to five years' time," Clemens Beckmann, head of innovation at the group's parcel and letter division, said in an interview with Reuters. The robots, which look like a table on wheels on which goods can be placed, would follow delivery workers, helping them to transport and carry heavy parcels. If the postie stops walking, the robot stops too, and it only starts again when they move on.

Today, Google announced the beta release of its Google Cloud Vision API. The API was designed to empower applications to both see and understand images submitted to the API. With powerful features such as label/entity detection, optical character recognition, safe search detection, facial detection, landmark detection, and logo detection; the Cloud Vision API gives applications unprecedented ability to comprehend the situation within an image. With the new API, Google enters a rapidly developing market where both startups and major enterprises are producing cutting edge technology. From Microsoft, with its Project Oxford, to niche startups like Cognitec and Lambda Labs; image analysis is proving to be an attractive space as it appeals across industries from marketing to security.
