Matrix Multiplication - Ex. 2

Patreon

I'm sure there's a reasonable explanation for it at the higher levels of math, but why is basic matrix multiplication Like That.

[lionmageaz]

A big shout-out to Volker Strassen and Shmuel Winograd for showing us more efficient ways to multiply big matrices!

I finally got around to writing a unit test for my implementation of Strassen's algorithm and tested it on a couple 8×8 matrices. Some of the numbers were good, but the lower-left quadrant of the result was way out of whack. Turns out I had the wrong order of matrix multiplication for calculating that quadrant, and once fixed, everything agreed to within an arbitrary 𝜀.

So now it works as it should, but timings reveal that for 8×8 multiplicands, at least, the naïve algorithm is much faster. I'm not sure what Nthreshold is for my implementation, but I'm guessing the real benefits would show themselves starting at maybe 128×128.

By the way I fully caught up to the story now— chapter three was really good, damn. Love seeing Hi3 coming back to their roots (“no we can’t sacrifice you for the greater good, we love you”)

Songque sobbing and begging Baiji to hurry up because she was so scared of death, praying for someone to save her but refusing to move herself hhhhhhh

Poor Songque has the self-worth of a wet sock, she couldn’t even compute Baiji complimenting her character, bringing up multiple examples to deny it.

Entropy chasing Songque’s illusion was heartbreaking, they were all doing different things too, gave them a lot of life, genuinely great usage of the setting there…

Props to Thelema for professing that she chooses Songque’s free will over saving the world when she could barely move herself. Props to Sera for comforting her hivemind in death. Props to Baiji for having the balls to say he’d still doom them all trying to become god if he had a do-over. Duonigue’s betrayal of Perception was hilarious I kept turning and he kept yelping hahahaha.

And Lantern!! Lantern during the boss fight!!! Lantern yelling for Songque, begging, insisting that she could beat Perception, because Songque is the only one who’d choose the world over her own life…

Songque is everyone’s favorite failgirl and they love her so much

(And I absolutely love the twist that even her name is a scam asjfhdkdhdj)

im of the opinion that rodimus never cries. ever. not even after nyon, which makes him feel like a monster for it. i also think hes the type to laugh at inappropriate times or have weird bursts of aggression and anger that he cant seem to trace. also would rather die before going to therapy. what do you MEAN chucking urself into extremely dangerous and life threatening scenarios isnt healthy. thats coping. hes coping.

furthermore hes one of those upbeat individuals who smiles and laughs when you ask him if hes okay and if you press it he gets pissed off. he said hes fine. leave it alone

(un)popular opinion: matrix should have been a standalone.

Have you ever managed your time so efficiently that you have zero assignments to do but having nothing to do is actually more stressful than if you had a heavy workload

Giving you a weary thumbs up from under a pile of rubble rn

Space mausoleum for all season 2 characters that died!!! Hello!!!!! The poor kid getting scared at all the robot CORPSES! Optimus tomb is EMPTY! hes fucking zombieing around up there.... its obviously suspicious but the new leader wants it to be true so bad he gives up the special artifact of leadership. GUH

Mausoleum? Destroyed. Entire bot fleet? Damaged from being lead into a trap by primes puppeted corpse.

And ofc. Undead prime getting autonomy back. Driving the now evacuated flag ship into the enemies for one last blaze of glory.

CMONNNNNNNNN

I fucking love my school the teachers are all such nerds this guy spent a full double period going on tangents about groups and fields and rings and left hand multiplication and I didn't understand any of it and I still don't know shit about matrices thanks to that but at least he was having fun

[71kedi-yip]

I did something

i find the dischotomy between the batfam's potential to kill vs their real-world willingness to kill very interesting! so I made a graph because I'm a nerd

Divine Talent

In the Matrix Destiny chart, I will be sharing a thread about the talent arcana energies, which is the position you most frequently ask about. The spot marked with X on the map is what we call divine talent, which represents the talents your soul is inherently born with in this life.

1 - You have many ideas and can generate ideas easily. When activated positively, you have the potential to succeed in whatever you touch.

2 - You can understand other people's motivations, that is, you can grasp why they do what they do at a glance. This gives you esoteric abilities.

3 - You have a good taste and a high sense of aesthetics. You have the ability to expand; you can turn a small task into big projects.

4 - You excel in team management and establishing authority. You have a strong talent for attracting money. If money isn’t coming to you, it means you are activating this area negatively.

5 - You have a talent for learning and teaching. You can master anything and explain everything you know in a way the other side can understand.

6 - Your communication skills and sincerity stand out. You are someone people come to for advice, trust what you say, and listen to your words.

7 - You have the ability to progress quickly in any job, reach your desired goals, and inspire change in both yourself and those around you.

8 - It's hard, if not impossible, for others to lie to you. You can approach everything objectively. You can achieve balance and harmony.

9 - You are more mature than your age, and this grants you wisdom. You have the ability to achieve your inner goals (knowing yourself, realizing your dreams and desires) on your own.

10 - This is a placement that brings luck. You have the talent to manage finances easily and spot profitable opportunities. You can easily attract people to yourself.

11 - Your physical and spiritual endurance is strong. You can do everything at once. You know your strengths and can use them in the most accurate way.

12 - Spiritual practices (like meditation, breathing, reiki) work well for you and have healing effects when applied to others. You have a different perspective and can solve seemingly unsolvable problems.

13 - You can make the necessary changes in every area of life and are not afraid to take risks. You can learn multiple things at once. You have the ability to easily absorb deep and detailed information.

14 - You have diplomacy and mediation skills. You can calm conflicts and maintain your composure during these processes.

15 - By opening yourself to others, you can show them what they cannot see in themselves. You can easily identify others' weaknesses, vulnerabilities, and talents.

16 - You are talented in directing people, organizing, and creating strategies. You can foresee events and chart your course accordingly.

17 - Your ability to express yourself is unique and creative. You can be the center of attention in any field you wish, shine, and stand out from the crowd.

18 - Your subconscious is very powerful. You may receive information through dreams, and your dreams may come true. Your manifesting ability is strong; everything you visualize can come into your life.

19 - You have leadership qualities and can inspire/give strength to others for success. You have the ability to not give up no matter what.

20 - You have good speaking skills and can influence masses. You can create systems from nothing and have excellent analytical skills. It's hard to confuse you.

21 - You have an aptitude for foreign languages and cultures. You can adapt to any environment. You can produce knowledge and content for a wide audience or listener base.

22 - Your decisions and thoughts may be unpredictable by those around you. You influence people with your positive energy. You can turn every tough task into fun and achieve results that will surprise everyone.
