@SallyStrange she deserves better behavior than smidges and tads tbh
@thief@weirder.earth Certainly. The wording reflects my opinion of the effort that would have been involved in not being so racist as to drive her away completely.
This chapter about melanin is so fascinating and surprising. Melanin is a conductor, that is also an insulator, depending on the presence or absence of water? Melanin could be a building material? Melanin could be the key to constructing materials for bioelectric implants? Awesome stuff, and Dr. Prescod-Weinstein is right to consistently rail against the exclusion of Black people from academia and physics in particular. Damn, Fedi, she was here and then she left. Imagine how much cooler this place would be if us white folks had been a smidge more hesitant to do microaggressions, a tad less disbelieving of the direct first-hand reports of racism and white supremacy from her and others like her.
Even though it's been a few years since I listened to this one, it often resurfaces in my thoughts. In short, the theory of #emotion presented in this book is powerful because of its flexibility and its ability to explain: - how #reframing is even possible - how there can be such large #emotional differences between cultural groups - how it could have been possible that the way humans construct emotion has changed over the course of #history
A fascinating book that looks at the history of Machine Learning (ML) to show how we arrive at the machine learning models we have today that drive applications like ChatGPT and others. Mathematics involving algebra, vectors, matrices, and so on feature in the book. By going through the maths, the reader gets an appreciation of how ML system go about the task of learning to distinguish between inputs to provide the (hopefully) correct output.
The book starts with the earliest type of ML, the perceptron, which can learn to separate data into categories and started the initial hype over learning machines. The maths are also provided to show how, by adjusting the weights assigned to its testing input, the machine discovers the correct weights which can allow it to categorize other inputs.
Other chapters then cover other ways to train a machine to categorize its input is shown, based on …

The maths are also provided to show how, by adjusting the weights assigned to its testing input, the machine discovers the correct weights which can allow it to categorize other inputs.
Other chapters then cover other ways to train a machine to categorize its input is shown, based on Bayes Theorem and nearest neighbour. They have their advantages and disadvantages: choosing the right (or wrong) way to train a machine will have an impact on how well the machine can categories its data.
Matrix manipulation, eigenvalues and eigenvectors are then introduced. When there are many input parameters, it can be hard to categorize them based on all the factors. By using eigenvalues and eigenvectors, it is possible to discover which factors cause the most variation among the data, and thus categorize them. And, in an interesting reversal, it is also possible to manipulate the input by putting them into more categories, which can reveal patterns that can then be used to categorize the input.
These ML models categorize input data using one level of 'neurons'. The next step would be to introduce a 'hidden layer' of neurons that can be used to combine the incoming data in many ways, which provides new ways to manipulate the data for categorization. This would provide a boost in the abilities of machines to recognize input data.
Lastly, the book catches up to current day ML models, which feature a huge increase in the number of hidden layers and weights used to manipulate input data. The book then points out that this huge increase has caused the theory of how machines learn to fall behind: the machines now exhibit abilities that theory cannot account for. The ability of such machines to pick out patterns in data through self-learning, rather than being pre-fed known data, is also an unexpected feature that current ML theories cannot account for.
These unaccounted features of current day ML systems are a probable cause of concern. So too is the concern over the kind of data being pre-fed to the systems: data that comes with various biases that only cause the system to make yet more biased decisions. Until we know better how these systems behave, it would be best to treat their outputs with caution.
Thousands of years in the future, humanity is no longer alone in a universe where a mind's potential is determined …
I have so many questions. Sound-based thought waves? The galaxy has speed zones? Ultimately though it was such a good story that I don't care much about the answers. I was super impressed by (since he was writing in 1993) and absolutely love Vinge's idea of a galaxy-wide internet that's hundreds of millions of years old and nobody knows who started it. That to me seems extremely plausible, given a universe with multiple sentient space-faring species. This was SO much fun, and anyone who loves science fiction should definitely read it.
Mostly action adventure with scifi accents. Cas makes a sympathetic protagonist, and there is some good character development. The background info about the scifi stuff leaves us wondering and wanting more, but that's a pretty minor concern since the action scenes are top notch. Fun read.
This version is based on the manuscript, rediscovered in 2017, from before the magazine editors started chopping out all the scandalous bits. The censored short version that was used against Wilde at his trial was then censored more when it was expanded into a full novel.
So now we get to see Wilde's original baby! Despite the censored version still causing a scandal and being used to convict Wilde, this is of course still tame by modern day standards (alas, where is my purity!) but far more explicit when it comes to things like Basil's romantic affection for Dorian. It's certainly fascinating to see what was triggering the poor little editor (being far more concerned about illicit hetero affairs than the gay stuff!) and also the stylistic changes. But either way, like much of Wilde's writing, it can't go a page or two without a little monologue of his witticisms …

Repeats some points made in "Escape from Freedom", with less of the psychological insight. The last chapter is very particular - it veers off into proposing a political program for the Socialist Party-Socialist Democratic Federation to develop what he terms Humanistic Socialism. One of the most notable points is his constant warning of the danger of mass manipulation by subconscious means.
