SergeyHack··on ChatGPT Search
For me it feels like Google is adding "buy" keyword to every search.

Part of the answer is here - https://www.wheresyoured.at/the-men-who-killed-google/

SergeyHack··on GitHub cuts AI deals with Google, Anthropic
The same here. It helps my slow autistic context switching a lot.

It's easier for me to recognize the ideas, concepts, keywords it has written than to recall them from memory when my "memory cache" is empty.

> You absolutely do feel the same feelings consuming porn as you do actually engaging in sex

I can't believe someone says this. It's so not true in my experience. These feelings have a lot in common, but they are definitely not the same.

+1. Here in Ukraine we see the same reasoning in Russian posts written by Kremlin trolls while they wage their information war against us.
SergeyHack··on NYT obtains internal TikTok document describing recommendation algorithm
The usual companies may not have ethics as you write, but politically motivated company can easily embed "ethics" in a recommendation engine like that.
SergeyHack··on Cultivate the Skill of Undivided Attention, or “Deep Work” (2019)
Vipassana meditation to reveal fears and other mental processes that are hidden. Also to repair focus disseminated by the modern culture of constant distractions. Even 15 minute session is enough to feel the potential and become more aware.

Sometimes this awareness is enough to change bad mental habits. But there are other things that you continue to do even if you understand that you don't want it. These are "imprints" NLP terminology.

To change these imprints my friend does really long Vipassana sessions for more than 10 hours. She claims to change at least one strong imprint that was "panic when staying at home alone". Which is related to an event happened when she was less than a year old.

I have not tried so long Vipassana sessions and to change my imprints I do Connirae Andreas "Core Transformation" technique. It's easier to have other person do it to you, however with enough determination you can train to do it by yourselves. Unfortunately it's still a lot of efforts to learn it. Anyway may be that helps.

SergeyHack··on For tech-weary Midwest farmers, 40-year-old tractors now a hot commodity
Interesting, could you give more details on that?
SergeyHack··on Shipping a Neural Network on iOS with CoreML, PyTorch, and React Native
Really great end-to-end write up.

Just a few things: in general case it's better not to use MSE after sigmoid due to slow convergence.

And "logits" variable is not logits actually, it's probabilities. Logits is what you have before applying sigmoid activation.

SergeyHack··on FastText – Library for fast text representation and classification
Sounds interesting. Can these tools work on character n-grams as FastText does?
SergeyHack··on LexVec, a word embedding model written in Go that outperforms word2vec
Not quite about creating synonyms, but in the same area there is Semantic Vectors https://github.com/semanticvectors/semanticvectors.

They process Lucene index and create embedded representation of it. Then you can search over that representation for "semantic" matches.

Last time I checked it about a year ago the embedded collection of documents was kept in the memory and the search was implemented by a linear scan. So I suspect it can be slow on very large collection of documents.

Imagine live edit of your video conversations, that attaches joyful emotions to any mention of an advertised brand.
SergeyHack··on Ask HN: What should we fund at YC Research?
Smarter agriculture. How to make Permaculture commercially viable while keeping it as ecological as possible.

The current agriculture is quite bad for soils and puts many chemicals into our food.

SergeyHack··on What Your Microbiome Wants for Dinner
I've heard a number of times that proper water fasting can heal diabetes.

P.S. Absolute fasting can be dangerous.

SergeyHack··on Deep Learning Adversarial Examples – Clarifying Misconceptions
The 6th point is very interesting:

"Adversarial examples generalize across models trained to perform the same task, even if those models have different architectures and were trained on a different training set."

"HOW TO CRAWL MARKETS" section has good tips for general crawling as well.
SergeyHack··on Show HN: Clojure by Example
To really feel the difference you have to work on complex logic.

It's easy to be under illusion that you can create everything using a verbose language. At some point the complex system you work on just gets extremely hard to reason about.

For verbose languages you reach this point considerably faster.

SergeyHack··on Google ATAP: Welcome to Project Soli [video]
I wonder what new possibilities for total spying this approach enables.
SergeyHack··on Ask HN: Sentiment Analysis – how to handle biased word list lengths?
You can try to find a dataset that contains the equal number of positive and negative documents (sentences, etc.) and use it as the validation set. I.e. to tune your hyperparameters on it.

In the simple case your hyperparameter can be α in

sentiment = (α * #positive_matches - #negative_matches) / (document_word_count)

SergeyHack··on Ask HN: Sentiment Analysis – how to handle biased word list lengths?
I like your "2." suggestion more, because the initial sentiment score distribution can be not normal.

So there is an option to try making it normal by taking logarithm for example and calculating mean, etc. after that.

SergeyHack··on The Power of the Doodle: Improve Your Focus and Memory
I wonder if doodling in this context is no more than a weak alternative to walking or other physical activity.

Have you considered sharing the data as a torrent? The current FileDropper speed is quite low (~200KB/s)

P.S. Thanks for the data, you saved a good amount of our time.

SergeyHack··on Deep Intellect: Inside the mind of the octopus
According to an interesting book of a Russian paleontologist Kirill Eskov [1] there were a lot of "evolutionary tries" to create a multicellular life. And as soon as it became "profitable" the regular try conquered the world.

IIRC it was related to increased oxygen level.

SergeyHack··on Show HN: A search engine that lets you 'add' words as vectors
The default example "justin bieber - man + women" was ok, but I have found a better one - "justin bieber - women + man "
SergeyHack··on Dear Google, Thanks For Copying My Startup But You’re Doing It All Wrong
BTW, your motto is not perfect IMHO.

"Experts" and "expertise" in "Find Experts. Sell Expertise" is too general. I would try to come up with more concrete examples though I realize it's not an easy task.

SergeyHack··on Dear Google, Thanks For Copying My Startup But You’re Doing It All Wrong
I think Live Ninja team realize this and they made this really good PR move. It really deserves upvoting IMHO.

SergeyHack··on word2vec – Tool for computing continuous distributed representations of words
TL;DR: The answer to your query is a person named Chaudhry Sitwell Borisovich who is definitely an entomologist-hymnist and probably is also a mineralogist-ornithologist.

A google search suggests that he was born in 1961.

I ran a few queries using the code and its default dataset, trying to use neutral words for substraction: "mosquito -small +mountaineer", "mosquito -big +mountaineer", "mosquito -loud +mountaineer", "mosquito -normal +mountaineer", "mosquito -usual +mountaineer", "mosquito -air +mountaineer", "mosquito -nothing +mountaineer".

The most frequent words for these queries are:

6 times: "borisovich" "chaudhry" "entomologist" "hymnist" "sitwell"

5 times: "mineralogist" "ornithologist"
