critiq··on Ask HN: How credible is Reinforcement learning in finance(stocks)?
Thanks for your reply
critiq··on Ask HN: How credible is Reinforcement learning in finance(stocks)?
Yeah thanks, I have tried, I was comparing and found reinforcement learning is not really reinforcement in this setting. As it cannot allow exploring like what if scenario. It is similar to supervised learning setting as we do in labeling large data and trying to classify etc.

In contrast if we take https://gym.openai.com/envs/Pendulum-v0/ Environment allows algorithm to play with it and learn from new conditions and actions, so is reinforcement. To me finance is like teacher trying to tell same story no matter what student does/learns, bit wierd.

critiq··on Ask HN: How to start a business where there is competitors already?
short answer: yes

  however there are many factors to consider before going that path
  * Low price start will be barrier for any future price changes or re-assesment.
  * There is quality perception attached to price so it impacts brand perception.
  * Even with price differentiation quality is something cant be compromised (in most of cases)
critiq··on How brain activity changes based on various activities
Thanks for both comments, as I mentioned in other comment I am curious if it can be fitbit for mind tomorrow :)
critiq··on How brain activity changes based on various activities
Yes I do understand it like measuring temperature at one point on mac and trying to predict what application its running. However thats not what I wanted (though I dont know what I wanted), I was curious how activity changes and If am not wrong these activity comes at cost both energy and capacity to think / focus. Who knows if you can wear fitbit for mind tomorrow :)

critiq··on Show HN: Yet another url shortner xiv.in, comments please
Yes agree that there is trust factor, also there are dozen of similar services. However I came across inquiries for shortening api services which are free / cheap. as per that there was bit of exclusivity required.

At the moment all still in flux. Thanks for your honest comments.
