Abstract: Partially relevant video retrieval (PRVR) is a practical yet challenging task in text-to-video retrieval, where videos are untrimmed and contain much background content. The pursuit here is of both effective and efficient solutions to capture the partial correspondence between text queries and untrimmed videos. Existing PRVR methods, which typically focus on modeling multi-scale clip representations, however, suffer from content independence and information redundancy, impairing retrieval performance. To overcome these limitations, we propose a simple yet effective approach with active moment discovering (AMDNet). We are committed to discovering video moments that are semantically consistent with their queries. By using learnable span anchors to capture distinct moments and applying masked multi-moment attention to emphasize salient moments while suppressing redundant backgrounds, we achieve more compact and informative video representations. To further enhance moment modeling, we introduce a moment diversity loss to encourage different moments of distinct regions and a moment relevance loss to promote semantically query-relevant moments, which cooperate with a partially relevant retrieval loss for end-to-end optimization. Extensive experiments on two large-scale video datasets (\ie, TVR and ActivityNet Captions) demonstrate the superiority and efficiency of our AMDNet. In particular, AMDNet is about 15.5 times smaller (\#parameters) while 6.0 points higher (SumR) than the up-to-date method GMMFormer on TVR.

Giving credit to the programmers of GPARTED(8)

gparted works its magic, by entering correct parameters to a suite of partition control & editing commands, which are sh envoked, so you can easily manipulate your partitions on all your SSDs HDDs from the comfort of your UI

When you want to batch manipulate partitions, you can study the log output and make sh scripts yourself, controlling partitions anywhere.
You also have the convenience of running gparted from sh so it still works its magic for you, without the UI!

I usually run cfdisk gdisk fdisk when I partition a fresh mechanical or SSD, later on I invoke gparted when I want to resize or move them

it also runs important commands at the end so that the kernel gets to know your new partition layout, which makes rebooting your machine to use them unneeded

I shrunk and resized a partition where I installed a program, which needed 75GB (*1024!) as installation space but only uses 56GB in the end. I left 12GB of breathing room on the partition after the shrink and of course grew the partition before with the same size, minus the alignment snip of 1MB

Since the /e/ Operating System is a fork from Lineage OS I was not surprised that my particular phone is not supported at this time

What is hot warming is the fact that capable programmers put their time, money, food & drink & sweat into enabling users to rip themselves from the grip of the Duo Poly which exists of Apple and Google

On this page you can clearly see how difficult Xiaomi makes it to install an alternative operating system; the bootloader unlocker is unbelievably, a program which is proprietary, and runs in a proprietary operating system. Now I still would have run it, if my model was supported specifically

Xiaomi only allows you to unlock four devices a year, just four devices a year

Those of us who have other phones can check if another Linux for Android runs on their device

Atm I'm looking at Lineage OS for my Android devices

I have scrolled through the most important parts of lineage us website.

One thing that you have to realize is that you're taking a grave risk when you are installing another operating system on the Android phone, at least that's what the manufacturer will tell you.

The manufacturer will **not** tell you that, you're freeing yourself from their **stranglehold** when you do this.
They will also not tell you that chances are, your device will work much more efficiently, because it will not have any bloatware, I repeat any bloatware what so ever

One thing they will never ever tell you, is that they make deliberately as difficult as possible for you to install another operating system, on your phone, your device, which you own, which you are the absolute Master of

The phone manufacturer will absolutely make sure, that they will never tell you, that they even put traps on your phone, when you install another operating system, just so that it bricks, so that you come running screaming and go back into their strangle hold

All these factors make installing another operating system on an Android phone risky, tedious, nerve wracking, and not worth it, if the phone is brand new, and the money you spent on it, isn't just chump change that you can easily afford if it breaks.

Just looking at the enormous list of do's and don'ts that you have to follow to the letter, clearly show per model, per manufacturer, how many traps have been put in, just so you are prevented to install another operating system, with which you free your phone from the stranglehold of the manufacturer, a phone that you have bought with your money, a phone that you own, a phone that you have the right to put whatever operating system you want upon.

On top of everything, your specific model of phone, needs to be supported even if there's just one letter difference, you should not even attempt to install that version of Linux on your phone, because the chances of breaking your phone literally bricking your phone, are astronomically High

The phone I need Lineage OS on is the one I'm working on right now, the phone overheats dramatically fast, has very poor physical Cooling, which became apparent when a broken patch was pushed to the phone, by Xiaomi, a couple of months ago.

Because of the overheating it needs to be shut down for most parts of the day making it a useless device

Xiaomi does the following to make it very difficult for you to unlock their fabricated devices:

* The boot unlocker is personal and you need to make an account for it
* An arbitrary limit is put upon the amount of Xiaomi devices that you can unlock per day per week per month.
* Every account can only unlock four devices
* Essentially Xiaomi is sending a f$ck you, towards you, as the owner of your devices, when you want to unlock the bootloader, so that you can put an arbitrary, much more stable operating system on the devices which YOU possess

My specific device is not supported yet by Lineage OS Xiaomi Redmi Note 12S
That means that I have to stop right there because the installation sequence specifically states that you need to double check that the image you put on the device is specifically designed for not only your model but your model to the letter so I need one for the Xiaomi Redmi Note 12S

By now I do not care which Linux distribution I put on this Android, just as long as it's specifically supported

The Journey through which I went to attempt to install Lineage OS on my Xiaomi Redmi note 12s has taught me the following

Android phone manufacturers do not like their clients. Android phone manufacturers detest their clients and treat them like slaves. Android phone manufacturers want their phones to be theirs forever, even when they sell them to you.

The rights to own a physical piece of hardware, are irrefutable yet manufacturers hate your rights in that respect.

Quite disturbing, this conclusion I came to, after the above research was done

The ones who pay attention, must have caught the typo that I've made when I entered the parameters in the permanent section {see above graphic}. I've also caught it when I booted the system and saw the omission. Naturally I corrected it and everything is fine now

I used the following command which a kind FediVerse user echoed to me

'cat /proc/cmdline'

Now you will ask why I put up a screen cap of Naked.Gun.33.1.3.The.Final.Insult in this thread.

The logic is simple. Because I now have tsc=unstable in my permanent boot options in GRUB, I have achieved playing this 1080p stream on my machine without any hickups of mPlayer!

mPlayer has the gorgeous option of bailing out by itself if you have CPU/GPU/FPU or RAM issues, protecting an unstable machine as my Gigabyte miniPC. Since the switch mPlayer did not have to bail out!
