Why is the goal in a multi-armed bandit problem of minimizing (cumulative) regrets?

In a multi-armed bandit, the goal is to maximize the expected cumulative reward. This goal is usually (equivalently?) Expressed in terms of expected cumulative regret.

Question: Why not just face the reward? Why formulate the goal in terms of regret?

goal – Why do not all zooms have a variable f-number?

Opening is a little abusive; a maintenance of times and simpler lens designs. What matters is the student of entry, or the apparent size of the opening seen through the front (objective) of the lens. With a simple lens design (double Gauss or Tessar, for example), the physical aperture and the entrance pupil are about the same size, but with more complex designs, they may have very little relationships with each other.

The same physical aperture (that is, the iris blades are held in the same position) may appear to be of different sizes for different focal lengths when it is seen at the same time. before the goal. Even with a typical mainstream lens, such as a 18-55mm f / 3.5-5.6 kit, the available f-stops do not match a constant size input pupil – a single lens with a focal length from 18mm to f / 3.5 requires a 5.14mm hole, while a 55mm lens at f / 5.6 requires a 9.82mm hole.

The difference between the actual aperture (the width of the blades to the diaphragm) and the entrance pupil results from the magnification of the elements of the lens between the front of the lens and the physical diaphragm.

Depending on how the zoom is implemented – how different lens groups are moved relative to each other – a given iris size can produce an entrance pupil that remains a fraction constant of the current focal length of the lens, regardless of the setting of the focal length. And if the lens is an internal focus design, it can also be done to stay at a constant effective f-stop at all focal lengths. (In a simpler classic design, the effective aperture decreases as you get closer to focusing.)

What goal should I buy?

New in photography and I found myself immersed in it, what an exciting and fun art!
I have a Canon Rebel T6 (1300D) supplied with the lens of the standard kit, as well as a 75-300 lens included.

My interests centers are people – photographing the seasons of people's lives, whether it's about engagement sessions, weddings, newborns, and so forth. I absolutely love the photographs with a shallow depth of field, I like the bokeh and I like to take pictures on the outside.

Here's my question – I'm ready to buy a goal alone, I do not know where to start with all the conflicting information you find online. I would like to buy the fifty owl, but with my cropped sensor, I know that it will act more like a 75mm lens and that this seems to present some shooting problems, for example, the newer ones. born at home.
I really do not know where to start and would like to have some tips. Do not forget that I am a beginner and that I wish the budget remains reasonable.

thanks guys

Can any one help identify this goal (close-up or what)?

T-mount from one side and something strange (similar to Arri PL? From the other)?

network – The goal of Zodiac FX (OpenFlow Switch)

I wonder how to remove the need for a router in a rpi system and came across Zodiac FX. Another site explains the difference with a traditional switch:

In a typical switch, packet forwarding (the data plane) and high-level routing (the control plane) occur on the same device. In software-defined networks, the data plane is decoupled from the control plane. The data plane is always implemented in the switch itself, but the control plane is implemented in software and a separate SDN controller makes the high-level routing decisions. The switch and the controller communicate via the OpenFlow protocol.

So, basically, the SDN system only requires the switch to process the data plane, and then a server / controller processes the control plane.

In these conditions, I wondered if we could explain exactly what the Zodiac FX does. It seems to be a new type of switch, which only deals with the data plan. But I'm not sure what that means in terms of data flow and how it works. You wonder if we could briefly explain how it works.

This site says:

An OpenFlow / SDN switch, when it receives a packet, for which it has no stream (match + port output), will contact an SDN controller (server) and ask it what it is must do with this package. The controller can then download a stream to the switch, possibly including packet manipulation. Once the stream is downloaded to the switch, it will switch similar wired speed packets …

So you have an FX rpi + zodiac, the rpi being the server / controller in the last block, the. Then he says "The controller can then upload a stream to the switchI'm not sure what that means.

business – the goal of posting free games online without having to pay money

There is some irony about asking this question on a site where people give their time to help other players without compensation. 😉

It's good to value one thing and find it rewarding even if you are not paid for it.

If I wanted to maximize my income, there would be many areas in which I would be better advised to work than game development. 😉

Instead, at least for me, I do it out of love for the challenge of gamedev himself and out of love for the game.

Seeing people enjoy a game that I've worked on is a huge win for me, even if it does not pay a dime: comment describing a family experience playing comment share a play of my game

By sharing this game freely, it allows more people to play, enjoy and share it than I think, even at a minimal price, which for me games) is an interesting trade.

Of course, there are also capitalist reasons for sharing things freely too:

  • test the waters to see if there is interest in the concept and gather feedback for a future commercial version

  • offering a "free sample" for marketing purposes for such a commercial version or such an extension

  • build a visible portfolio and reputation to demonstrate your skills to potential employers

  • Foster and entertain an audience of followers that you can tap into to access future opportunities

… but what I mean is that these are not the only things that can make it satisfying and useful.

The free content sharing may not enrich my bank account, but I believe / hope that, in a way, it will enrich the world.

Divergence between events and goal achievement

There was a difference between events and achievement of goals in Google Analytics.
These events are sent from Salesforce using the measurement protocol and do not match the achievement of the objectives.

Do you have any suggestions or ideas?
Thank you in advance for your time.
