Question of the day: How would one model how much money was spent trying to convince conservatives to vote for the Democratic party, and what would happen if more of it had been spent on Black and Latina organizers?

Important paper from Google on large batch optimization. They do impressively careful experiments measuring # iterations needed to achieve target validation error at various batch sizes. The main "surprise" is the lack of surprises. [thread]

The paper is a good example of lots of elements of good experimental design. They validate their metric by showing lots of variants give consistent results. They tune hyperparamters separately for each condition, check that optimum isn't at the endpoints, and measure sensitivity.

They have separate experiments where the hold fixed # iterations and # epochs, which (as they explain) measure very different things. They avoid confounds, such as batch norm's artificial dependence between batch size and regularization strength.

When the experiments are done carefully enough, the results are remarkably consistent between different datasets and architectures. Qualitatively, MNIST behaves just like ImageNet.

Importantly, they don't find any evidence for a "sharp/flat optima" effect whereby better optimization leads to worse final results. They have a good discussion of experimental artifacts/confounds in past papers where such effects were reported.

Hey, who wants to read a story about @Upwork fucking over freelancers in order to upsell their clients on unnecessary services the clients don't want and can't afford? Strap in!

So after my marketing agency closed I started freelancing again. A marketing company that wanted to work with me only hires freelance writers through @Upwork. So I signed up. I wasn't thrilled about it, but that's who they contract with and it's their marketing company.

I've been receiving regular assignments from this company, thru @Upwork, for over a month now. I've written dozens of articles for them. My work has been exemplary. I've been handling repeated rush jobs and delivering. The client was and is very happy. That's coming from them.

While I was wrapping up several assignments this week I was contacted by the marketing company. They asked if I had taken a new full-time job and wasn't available anymore. It seems @Upwork's talent group told them I was no longer available to take assignments.

I was very surprised. Nothing had changed on my end. I still needed the freelance work very much. I told them so. So the marketing company pressed @Upwork and were told there were "compliance" issues that were preventing the marketing company from giving me any more work.

Time for a Thread🧵On yesterday’s “F&O Pe Charcha - Diary Of An Option Seller” with @Mitesh_Engr by @Paytm Money

Why Gain/loss ratio is important that the batting average
• More than the Win Loss ratio check the total Gain /loss ratio
• If your avg loss is 1% and avg gain is +5% then even if you are losing in 7 positions and winning in 3 out of 10 still you will be net profitable

Treat Trading as a business:
• Stick to a single strategy. Eg: A restaurateur usually wouldn’t be changing his recipe on a daily basis
• Mitesh Sir only works on BO or BD strategy, as he is a versatile trader

• Any trader should atleast experience 3 scenarios i.e. bull, bear & consolidation
• Target 4% per month i.e. 48% p.a.
• Option buying requires skill, everyday there wont be huge momentum, so buying options won’t yield good results, but high chances of falling into a bad habit

Stock Selection:
• In F&O segment there are ~150 stocks
• Not everyday all stocks will move
• Only 5-7 stocks move upside or downside
• Focus only these momentum stocks
• Check which one is moving
• Range BO/BD never disappoints. BO/BD from a rectangle (consolidation)

Andy McCabe has some explaining to do.

Andrew McCabe was reported to the FBI’s Office of Public Affairs for making an unauthorized leak of classified info to the media about @GenFlynn in early February 2017.

If you’ve wondered exactly who it was who leaked the classified info from that intelligence report on @GenFlynn’s phone calls with then-Russian ambassador Kislyak to the media, you are right now seeing a huge honking clue who it was.

To those responding to this info by sneering "Nothing's gonna happen":

Up.

Your.

Game.

You just might be too stupid to be following me.

The then-Deputy Director of the FBI get's caught targeting @GenFlynn with an illegal leak so he can 'investigated' by Peter Strzok?

Now that we know it was McCabe who set up Flynn for a fake 'perjury' investigation by his pet attack dog, Peter Strzok, the next name that's going to surface is...Joseph Pientka.
