dnd 5e – Is there an ability, spell or magic item that lets you detect an opponent’s intelligence stat?

Insightful Manipulator accomplishes this

Insightful Manipulator is a 9th-level subclass feature for the Mastermind rogue, the ability is as follows (Xanathar’s Guide to Everything, page 46):

Starting at 9th level, if you spend at least 1 minute observing or interacting with another creature outside combat, you can learn certain information about its capabilities compared to your own. The DM tells you if the creature is your equal, superior, or inferior in regard to two of the following characteristics of your choice:

  • Intelligence Score
  • Wisdom Score
  • Charisma Score
  • Class levels (if any)

At the DM’s option, you might also realize you know a piece of the creature’s history or one of its personality traits, if it has any.

Access to this feature will allow your character to know if another creature has a higher intelligence score than himself.

artificial intelligence – How to OCR and/or recreate lines of Egyptian Hieroglyphs in Unicode/HTML?

I am wondering how to take these Hieroglyphs and make them into Unicode. I read through the Tesseract docs on how to create training data, but it seems largely tailored toward “traditional” writing, that goes in one direction and has only one character per vertical-space-per-line. Whereas in Egyptian hieroglyphs, it is sort of nested writing, you might have 3 characters stacked vertically, followed by 2 characters stacked vertically, etc.

So I’m wondering what the best option is for doing the full spectrum, of taking one of the hieroglyphic images in that book, like this:

enter image description here

And layout not completely horizontally like this:

𓏺 π“‚‹ π“ˆ– π“‹΄π“‹΄π“ˆ–π“π“‚Š π“Š‘π“…±π“ͺ π“…œπ“…œπ“‚ π“ˆ— π“…œ π“†„π“ŠΌ π“Œƒπ“†“ π“‡‹π“ˆ– 𓃉𓃉𓃉𓃉 π“Œπ“Œπ“Œ π“€”π“€€ 𓃉𓃉𓃉𓃉 π“‡‹π“€ž 𓏏𓍃𓀭 π“‚žπ“Ž‘ π“ˆ–π“€€ π“Š‘π“…±π“ͺ π“‡›π“…œπ“œ π“‡‹π“Άπ“…œπ“­ π“ˆšπ“‚‹π“π“ƒΏπ“Ž‘ π“Œπ“Ž‘π“€€ π“‹΄ π“π“ˆ–π“‚˜ 𓃀𓏏𓉐 π“Ž€π“…±π“‡Œ 𓁷𓂋 π“‹π“Ž€ 𓃹 π“ˆ–π“Œπ“…±π“Š– 𓇋𓅱 π“€Ίπ“„Ώπ“‚‘ π“ˆ–π“€” π“‹΄π“…±π“Ž›π“π“†‡ π“Ž€π“…±π“‡Œ π“ˆ–π“ π“ŽΌπ“ˆ–π“ŽΌπ“ˆ– π“…¨π“‚‹π“€­ π“‚‹π“…±π“‚§π“―π“œ π“€€π“‚‹π“…±π“‚§π“―π“œ 𓏛 π“‹Ήπ“ˆ–π“π“€€ π“‹Ήπ“ˆ–π“ 𓏛 π“‹΄π“‹΄π“ˆ–π“‚Š π“Š‘π“…±π“ͺπ“‰˜π“€€π“‰ π“‹΄π“‹΄π“ˆ–π“ƒΏ π“Š‘π“…±π“ͺπ“‰˜π“›π“‰

but instead layout in HTML exactly like they are laid out in the original textbook.

What I would imagine to do is, use OCR (or similar technology?) to identify the individual glyphs. I would manually draw squares around characters and map them to unicode characters. Then I would go and use that as training data somehow. Then it would go, page-by-page, through the document, and layout the text as it sees it in the document (with Egyptian Hieroglyphic quirks and all, everything in the proper place). I would imagine that there would be some tool that could use my manually trained squares and return { x: ..., y: ..., w: ..., h: ..., char: ... } for each glyph it finds. Then I can simply do my think with that data and convert it to HTML with CSS and absolute positioning.

The question is, how do I do that middle step? How do I do everything up to the HTML portion even? Should I be looking at Tesseract, or is there a more general tool like an “image recognition” tool that I could use to take my models (of some kind, x/y/w/h perhaps of boxes) and return my x/y/w/h/char array for each page. How can I do that, at a high level? I can figure out the specific CLI commands to run, or library API methods to call, I am just not sure what the state of the art is here and what type of tool would be best and easiest in this case.

artificial intelligence – Find optimal Vector for a dataset equation problem

Is there an algorithm or an efficient way to solve the following equation

$S=
frac{
begin{bmatrix}
R_{1} & . & . & R_{n}\
end{bmatrix}
begin{bmatrix}
P_{1}\
. \
. \
P_{n}\
end{bmatrix}

D_{m,1} & . & . & D_{m,n}\
end{bmatrix}
begin{bmatrix}
P_{1}\
. \
. \
P_{n}\
end{bmatrix}right)}$

With known values for:

  • $D$ is $m$ x $n$ Matrix
  • $R$ is $n$ x $1$ Vector

Need to calculate the values of:

  • $P$ which is $1$ x $n$ Vector made of non-negative numbers, sum of all is 1.0

To achieve maximum value for scalar $S$, however its value is not important.

Note in the above equation $D P$ produces a $n x 1$ vector, and $Maximum(D P)$ represents highest numeric value from it.

artificial intelligence – Simple formula comprehension: help medical worker who are struggling to understand AI

https://www.nature.com/articles/s41467-020-17419-7

I am a medical school graduate and I really want to learn AI/ML for computer-aided diagnosis.

I was building a symptom checker and I found the material. It clarifies the drawbacks of associative models which are performing differential diagnosis. And it suggests counterfactual(causal) approach to improve accuracy.

The thing is I couldn’t understand what the formulas mean in the article, e.g.:

P(D∣E;θ)

I really want to know what | and ; are doing here, what do they mean, etc.

I would really happy if someone can directly answer or just provide me some references to get general idea quickly.

dnd 5e – Can a 6th level rogue select Investigation for their Expertise feature even if their Intelligence modifier is +0?

So I started playing d&d a while ago, but when I was building my first character ever I didn’t completely know what I was doing so I assigned my rolls to abilities I didn’t totally need to have high stats to and vice versa. Anyway, I’m playing a rogue and I’m at a point where I can pick two things I can double my proficiency with (6th level Expertise feature). I need better Investigation to check for traps etc., but my Intelligence is 11(+0).

My question is can I pick Investigation as one of the things I can double my proficiency with? In other words if my proficiency bonus is +3 (so +6 at this level cause I get to double it)when I roll for Investigation can I add that proficiency bonus to my Investigation roll even though I have +0 intelligence?

dnd 5e – Are there any practical reasons for choosing proficiency in Intelligence saving throws?

Int saves are really good against Mind Flayers and also some other spells

Few powerful spells require you to use Int saving throws, additionally from my experience some of these are often used in Dungeons or by BBEGs to screw PCs over. They are:

  • Feeblemind
  • Symbol (insanity mode)
  • Phantasmal Force
  • Mental Prison
  • Psychic Scream
  • Illusory Dragon (Save for Dragon Breath, Investigation check to see through illusion)
  • Synaptic Static (This is actually a useful AOE for PCs as well)
  • Enemies Abound
  • Contact Other Plane (When cast by you)

The dreaded Mind Flayer’s Mind Blast ability requires an Int saving throw

Mind Blast (Recharge 5–6). The mind flayer magically emits psychic energy in a 60-foot cone. Each creature in that area must succeed on a DC 15 Intelligence saving throw or take 22 (4d8 + 4) psychic damage and be stunned for 1 minute. A creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.

And so do their tentacles

Tentacles. Melee Weapon Attack: +7 to hit, reach 5 ft., one creature. Hit: 15 (2d10 + 4) psychic damage. If the target is Medium or smaller, it is grappled (escape DC 15) and must succeed on a DC 15 Intelligence saving throw or be stunned until this grapple ends.

Having Int save proficiency in campaigns that deal with mind flayers a lot is very usefull


Intellect devourer’s devour intellect is another Int save ability

Devour Intellect. The intellect devourer targets one creature it can see within 10 feet of it that has a brain. The target must succeed on a DC 12 Intelligence saving throw against this magic or take 11 (2d10) psychic damage. Also on a failure, roll 3d6: If the total equals or exceeds the target’s Intelligence score, that score is reduced to 0. The target is stunned until it regains at least one point of Intelligence.


Finally as was pointed out in the comments, a recent Unearthed Arcana contains three psionic focused subclasses and introduces new abilities and spells that require Int saving throws.


For what it’s worth though I agree with the question and as far as I know Intelligence saving throw proficiency is generally considered the weakest one.

dnd 5e – Does feeblemind change the effect of Command Undead on high intelligence targets?

(As long as the creature fails the feeblemind save)

A creature can only continually save against Command Undead if it has an intelligence of 12 or higher:

If the target has an Intelligence of 8 or higher, it has advantage on the saving throw. If it fails the saving throw and has an Intelligence of 12 or higher, it can repeat the saving throw at the end of every hour until it succeeds and breaks free.

Feeblemind is Instantaneous and the affected creature doesn’t get to save again for 30 days:

At the end of every 30 days, the creature can repeat its saving throw against this spell. If it succeeds on its saving throw, the spell ends.
The spell can also be ended by greater restoration, heal, or wish.

Also, feeblemind reduces Charisma too, so it is almost certain that the target fails the Command Undead save (since it would then have a -5 Charisma modifier).

Be mindful of Legendary Resistance

While keeping feeblemind active on a target is usually easy (as their Intelligence is reduced, so they almost certainly fail the 30 day save), traits like Legendary Resistance mean that the creature can choose to succeed anyway and break free after the month.

Make sure you command the creature not to use Legendary Resistance on feeblemind (or have it use up it’s charges before the end of the day to be safe).

artificial intelligence – Is an AI upscaler incapable of reducing entropy?

I was reading the description of Anime4K (a video upscaler software) and I found a statement triggering my attention:

(upscaling is done) without any meaningful decrease in entropy (lost information
is lost).

If someone sits down and redraw a cartoon, they may be perfectly capable of using their experience to undo the effect of a terribly lossy compression, inferring lost information pretty much as the author intended it to be. A well-trained AI is capable of the same process, isn’t it?

And, even if the reconstruction process adds details which were not in the original, producing a different but more enjoyable result, can we say that we did not have any meaningful decrease of entropy?
