reward | Reinforcement Learning in PyTorch | Reinforcement Learning library

I'm learning about policy gradients and I'm having hard time understanding how does the gradient passes through a random operation. From here: It is not possible to directly backpropagate through random samples. However, there are two main methods for creating surrogate functions that can be backpropagated through.

They have an example of the score function:

I am trying to create a timer app which have multiple countdown timer for different task. Issue, I am facing is that, if I start one timer, and press back button, timer stops. So I want, that timer to run till either it is being paused or timer ends and alerts the user or app is destroyed. Help me how can I do this using Flutter? Any Sample Code Will be Appreciated? Solution will be rewarded

I'm new to admob. I published my first android app (written in expo react-native). I followed the instructions https://docs.expo.dev/versions/latest/sdk/admob/ on including admob ads in my app. But after sometime of including the ad Ids for Banner Ad, Interstitial Ad and Reward Ad I get this message "Ad serving is limited The number of ads you can show has been limited. For details, go to the Policy center" in my admob account.

It says "Invalid traffic concerns". I followed the below links but it didn't help me resolve it

Resolutions I followed but none of these helped

1. Removed all 3 ads i,e, Banner Ad, Interstitial Ad and Reward Ad. After waiting for couple of days (5 days or so) this message was removed. After one day I again created these ads and implemented their Ids in my app and released it on Google Play Store. Ads did not show in my app but still, after 2 days I again got this "invalid traffic concerns" message on my account.

2. Implemented frequency capping for the ads but that didn't help. Ads are not showing on my app yet.

3. I've implemented ads.txt properly.

4. I've added the payment details on the account.

5. Implemented the test ad Ids and they worked. But when replaced with real Ad Ids they don't work.

None of these helped me. Please let me know how to proceed on this.

By the way, this is my app - https://play.google.com/store/apps/details?id=com.starcoding.matchmeifucan_cow_bull

Thanks.

I am trying to set a Deep-Q-Learning agent with a custom environment in OpenAI Gym. I have 4 continuous state variables with individual limits and 3 integer action variables with individual limits.

Here is the code:

I am developing game, which guesses number and get reward if they success. This is summary of my program. First, user send amount of sol and his guessing number. Second, Program get random number and store user's sol to vault. Third, Program make random number, if user is right, gives him reward.

Here, how can I check if the user sent correct amount of sol in program?

This is test code for calling program.

I was trying to claim the staked $Aurora rewards with NEAR-CLI by following this medium article but when I run the command:

NEAR_ENV=mainnet near call aaaaaa20d9e0e2461697782ef11675f668207961.factory.bridge.near storage_deposit ‘’ --accountId bailey12.near --amount 0.0125

The terminal displayed:

I have this custom callback to log the reward in my custom vectorized environment, but the reward appears in console as always [0] and is not logged in tensorboard at all

I'm learning AI and machine learning, and I found a difficulty. My CSV dataset has two important columns which are dictionary themselves, e.g. one of them is categories which presents the info in each row like this {"id":252,"name":"Graphic Novels"...}, I'd like to explode this data so it shows in individual columns, for example cat_id, cat_name... so I can apply filters later.

I guess there are some options in Python and Pandas but I can't see it right now. I'll appreciate your guidance.

Edit: I took the first ten rows in Excel, copied them to a new document and then opened the new csv document in notepad, copied the first ten lines in notepad and pasted them here, the document can be found in my gdrive :

i was trying to set up simple ad system in my game in unity but the rewarded ads script from unity documentation is giving me invalid token error and i have no idea why
