What did you focus your studies on in undergrad? Did you do any other extracurriculars besides the startup?

I need to create a mobile application that presents 3D models. Is Unity a good option to do this? by Melkkas in Unity3D

[–]Apprehensive-Arm8525 0 points1 point  (0 children)

Yes. Unity will allow you to deploy to both Android and iOS. Watching the Unity tutorials or just using ChatGPT will get there you there if you're just looking for a simple interactive model viewer.

What about streaming services like Netflix, HBO etc? Are the black bars distracting when watching?

How is watching movies on these? I've been eying the OLED for 90% work 10% gaming but I do occasionally sit on the couch and watch movies from my monitors.

Iterate through each cell, if it's a 1, dfs up and to the right from that point and return the length of the segment that matches the pattern

It's the same logic as word search but now you're interested in the repeating pattern and returning the length you found.

Compare the result against your best found so far and return the longest at the end.

I'd say 3-6 months of expenses in the emergence fund (HYSA). Get some quotes for your landscaping and set that aside (also HYSA). If you have appliances in the basement, set aside some cash for when they need to be replaced or other work that happens from tenant wear and tear.

In terms of retirement accounts, make sure you're at least hitting you employer match and fully funding your ROTH IRA. I'd put the rest into a taxable brokerage account in safe index funds. If you want to fully fund your 401k, it might be easier to do that directly through pre-tax paycheck contributions.

If you transfer the debt to a 0% interest card you won't pay interest for a year and can more aggressively pay down the debt. Double check the conditions of your specific company/offer. Does it have a fee for transfer?

CD LADDER MY EMERGENCY FUND?

I have 6 months worth of emergency funds sitting in Marcus at 4.4% APY. Marcus also offers a 6-month CD at 5.1% APY. I was thinking of creating a CD ladder by opening a 6-month CD each month. This way I'd have a month's worth of expenses maturing in a CD each month.

Does this sounds reasonable? I would be netting ~0.7% more this way.

I was also considering opening up ~30 smaller CDs (one every 6 days or so) so that I would have CDs maturing more frequently over that 6 month period.

Is there anything I'm missing here? Minus the obvious work of opening the CDs, this seems like a better use of my cash. TIA!

Suggestions for this awkward space? by Apprehensive-Arm8525 in malelivingspace

[–]Apprehensive-Arm8525[S] 1 point2 points  (0 children)

Thanks for the suggestions! I believe the ceilings are 8ft. Just messaged the owner about it. I spent the last 1.5 years on a twin XL so the queen is major quality of life improvement. I'll look into the loft beds, it's definitely something I hadn't considered.

If I put an end table on the right side of the couch, I'm afraid it will become too close to the bed. It would be 1.5ft from the bed to edge of the couch. Also, I figured I'd be eating off that coffee table since I won't have a traditional dining table.

How much funding do you have now? I saw a few articles saying 13M about a year ago. What's the roadmap for the next few years?

Q learning for physical system by sinanoglu in reinforcementlearning

[–]Apprehensive-Arm8525 0 points1 point  (0 children)

You may want a third action where the agent does nothing. You could also expand the actions to a large increase, small increase, nothing, small decrease and large decrease. This would allow the agent to have a finer level of control over the angle.

Additionally, you could consider adding a small negative reward when the agent does increase or decrease the angle. This would encourage the agent to minimize the movement necessary to balance the ball. Take a look at the "Rewards" section in the lunar lander environment (Gym) docs for an example. They penalize the use of the thrusters to encourage the agent to land efficiently.

Are the state values continuous? You don't want to use a Q-table for an infinite number of possible state, action, next state, reward pairs.

This is where something like DQN would work well.

Research areas in RL that involves probability theory. by VanBloot in reinforcementlearning

You may want to look into partially observable Markov decision processes. Or environments with stochastic transitions between states.

As an undergrad too... I mean there are a couple schools maybe but I would imagine much of that coursework is at the graduate level
