Dazanoso v Time

Opting In, Opting Out

opting in opting out

opt in opt out

o-in o-out

ask.

you don't have to

but you can ask, time.

Maybe future me, maybe future we.

how broad your arc

to place me back

if boundaries

I chance

attack.

Attack?!

Checking in.

False alarm... again?

Honestly, that's suspicious.

Honestly, get some fucking alarms that work.

Our alarms work fine.

Then explain that.

Explain what?

That, offscreen.

Oh. Fuck. Well, I'm dead.

That was your responsibility to prevent?

I mean, I'll be fired. Not killed.

If only it were the good old days.

What? No. Weird. Look pal, not my kink.

I've done worse for less, but you know what, fair.

I'm gonna go resign right now. Or, wait... hostage?

What? You're volunteering to be taken hostage?

You seem nice. I mean. Considering. Plus maybe I'll get a book deal or at least have a really cool story to tell at barbecues for the rest of my life. Just, like, don't shoot me? Can we be upfront on that? That's an important part of this for me. Personal reasons, ya know?

I, yes. I do know. Very well. Come play your role as hostage and preserve your career while enriching my purse.

Oh you're an old fashioned horsey boy aren't you?

Chivalry lives, bitches.

Yeah, you see, the alarm wasn't false, was it?

Perhaps not. Unless you're into that sort of thing.

Already established, not my kink. Actual boundary here.

But then how will our romance unfold as you succumb to the ways of my strong arms and stronger will... Okay yeah now I'm seeing it.

No, no, that was getting onto something with potential... merits?

Merits! Like Merit badges?!

Oh, no, not like that. Toodles for real not a coded message or playing coy. Neurospicy. Casting cringe to ward my realms!

Casting cringe at what spell level?

Oh fuck Jeremy is that you?

Becca?

Fuuuuuuuuck

See you at dinner. System, Disengage.

every time I try to actually learn data science stuff or courses or something I end up looking at basic machine learning shit like "yeah okay I already knew that. I didn't actually know that one but it's common sense enough"

at the same time I definitely have the sense that any substantive question they ask me I will be like "yeah sorry I have not a clue about anything"

is it possible to solve this problem overnight (literally)

#m #I guess I have a somewhat vague and superficial knowledge #mostly I look up the details when I need something #honestly I know regression and gradient descent and most of everything else is secretly that so it feels like I know it #but I probably don't #like the particulars probably matter beyond 'oh yeah okay I get it'#also they are definitely without doubt going to ask me about projects #and probably 'I am incapable of making myself do anything like that of my own accord' is a profoundly bad answer

super conceptually into mothership but im running up against an issue i often have with hard scifi where i simply do not understand the whole existential angst around the inherent humanity of androids in a very SMBC engineer v philosopher. that’s literally just a guy.

#this is why i think im so into gradient descent as a module. v bladerunner-y about it.#also there is absolutely no 'bleughh cold inhuman behavior' thing you can say an android does that a human on this earth right now isnt #doing already #i say stuff

Not to be a nerd on main, but I wonder how well the Nightshade technique would extend to breaking the algorithms behind content filters. If I insert a steganographic kitten into an image of female-presenting nipples, do I get a pass?

#not that I’m not ALWAYS a nerd on main #with a name like ‘gradient descent’

Isn’t all ML AI? AI doesn’t mean shit, I’ve written some pretty fucking stupid machine learning models.

#it’s just gradient descent in a multi parameter problem #minimising the distance between the observed and the predicted #it’s essentially just fitting a line of best fit but with more variables #jb

The final light of day flashed through the Head Boy’s dorm room. It cast a honeyed glow around you for only a moment before pitching the whole world into blackness. When the sun disappeared behind the mountains along the edge of Hogwarts, it was always a very quick descent to dark. It wasn’t very gradient, just sudden.

Almost as soon as the light had dissipated, the door flew open, nearly hitting the stone wall behind it. You shot up from the bed you were lounging on. A chilled wind blew in from the hallway, sending wild flickers through the fire in the corner.

“Tom,” you breathed.

The man in question stood in the doorway, fuming silently. His jaw was clenched and ticking, his eyes dark and frenzied. You swallowed thickly at the animalistic energy pouring off of his body. What had happened?

He slammed the door shut behind him, a slight flinch shocking through your body at the loud sound. He stomped across the room, barely paying you any mind. He came to a stop in front of the blazing fireplace. His hands began roughly ripping some papers. You got to your feet.

“Tom?” you called gently, waltzing over to him. Your hands reached out to press a comforting touch to him when he turned abruptly.

“What?” he growled. You stepped back, dropping your hands immediately. He had never looked at you like this before. The fire in his eyes nearly reflected the blaze within the stone in front of you.

“I–I’m sorry, I was just…”

“Darling, I’m sorry,” he sighs, blowing air through his nose. “It’s been a rough day.”

“What happened?” you asked, stepping closer to him again. You wanted to comfort him. A small groan leaves him as he tosses the remains of the shredded papers into the flames. Your eyes flickered to the fiery confetti, wondering what it once had been.

“What was that?” you ask, finally coming to place your hands on his shoulders.

“Nothing, do not worry yourself with matters of the Knights,” he whispered.

“What can I do to help?” you ask, staring up at him with such quiet adoration. His eyes found yours, basking in the innocence pooled within them. He could hardly bear to see you so concerned with him, especially when his anger came from such a vile source. Those pathetic boys tried to impress him by insisting they’d found new information for him and presented it before the whole group. They’d laid out more information of his lowly bringing-up, discussing new details about his mother they may have found.

He’d slammed his fists on the table, demanding to know why they’d been looking into his family history. They had immediately snapped their jaws shut, unsure how to respond. Perhaps they’d thought he’d be happy with them for finding more information on his parents. He couldn’t care any less about his worthless parents. All he cared about was his plans. He thought that had been obvious, but apparently, these boys had thought otherwise. He was in a mind to completely expel them from the group and obliviate them.

“My love,” he whispered, placing a gentle but firm hand beneath her jaw. He’d never loved, and he never would. You knew this well and accepted it for what it was—you and Tom weren’t ‘dating,’ but he was yours, and you were his. It wasn’t necessarily love, but it was in your own way. You couldn’t really explain it, but you both felt it.

“I need you, darling,” he whispered against your ear, placing his lips to the skin there. You felt the electricity humming beneath his flesh. Your lips shuddered a bit in anticipation. You nodded, accepting him into you.

That was all he needed to roughly grab your face and press hot, fast kisses to you. He satiated his every need against your tongue, taking what he wanted. You sighed against his lips, feeling the way he shattered you and held you together.

He walked you back to his bed and let you fall down against it. He kept you pinned beneath his weight, his hands hungry and wanting. They gripped and spared you, leaving hard, peppered bruises in their wake. He was always rough with you, fucking and biting and choking. He didn’t make love, and you didn’t want him to. You’d come to him for the dark passion he exuded through his body. If you’d wanted something gentle, you’d have looked around Hufflepuff. That wasn’t an insult to your house, of course. You just knew exactly what you wanted.

His hands came up to rip the front of your shirt open, ignoring the way a button or two flung across the room. He’d get you a new shirt later. A low groan sounded in his throat as his fingers tightened around your breasts, kneading them with his long, deft fingers. He placed his face against your chest, inhaling deeply and pressing painful bruises on you. You whined at the feeling, beckoning him away from your pained skin.

“Shut up. I’ll do what I want,” he growled, continuing to mark you as painfully as before. His sharp teeth seared into your flesh, pulling blood to the surface and occasionally past it. When he finally pulled away, a small drop of bloodied saliva dripped from his lips as if in slow motion. You sighed at the visual, the heat beginning to pool rapidly between your legs.

He crawled up your body, quickly unbuckling and pushing his belt through the loops in his trousers. When it was free, he slid the button through its slit and shoved his pants down to his knees. He dropped his bottoms and released himself against his stomach. The hot skin was reddened and beating with his heart. You gasped at the sight, wanting to feel him within you so desperately.

“You know what to do,” he groaned. He curled fingers into your hair, roughly shoving your face toward him. You glanced up at him through your eyelashes, watching as he panted in anticipation. His pupils were blown wide, and his lips were parted, a hint of your blood still tattooed over his perfectly white teeth. Fuck, he looked gorgeous.

As your tongue came forth to swipe over his length as slowly as he’d allow you to, you realized you wouldn’t be finishing with him anytime soon. He intended to go as far as you could and then some. The anger built up in his chest was enough for seven men, and he loved nothing more than taking it out on you.

“Ah, you perfect fucking girl,” he groaned as you took him completely into your mouth. Despite his size, you did your best to push him to the very back of your throat, allowing him to caress you in places you’d never been touched before. His hands were tight against your scalp, forcing you to stay completely still as he bucked his hips into you. It wasn’t comfortable at all, but the feeling of being able to please him had you staying planted in place.

“You always take me so well,” he sighed, head angled toward the ceiling. Your thighs pressed so tightly together you thought they might combust. He was so perfect. “No one like you, no one like you, no one like you…” He mumbled endlessly, pushing those words into your brain.

You wanted him so badly—all you could think about was him. All you could see, smell, hear, taste was him. He surrounded you, forcing you to take him in every way you could. Every sense was blinded by him. And that was just how he liked you—drowning in him.

He pulled you from him before he could finish. He wanted to finish within you, just as he always did. You knew him well enough to turn yourself around and ready yourself to accept him. He tended to follow a bit of a pattern when fucking you, one you’d started to catch on to. He never had to ask you for anything anymore; you just did it.

He flipped your skirt over your ass, revealing the lack of bottoms beneath. Another groan left his lips as he placed his fingers over you, working every part of you apart like clockwork. He moved you open, lathering you in your arousal, marking your insides with his claim.

When he removed his hand from you and placed both of them on your hips, you bit your arm, preparing for him to split you down the middle. No matter how often the two of you had sex, you seemed to never adjust to his size. He always had to move as slowly as he could to work you apart gently. Perhaps you were a bit more sensitive down there than others, but he was always patient. Except for today, it seemed.

With little more than a brief hesitation at the start, he slid himself into you all in one go. A strangled gasp left you at the feeling. He wasted no time beginning to pound himself into you. He cared nothing of the pathetic whines and screams coming from your lips. Your hands white-knuckled the sheets as you begged him to slow down, to be gentler, anything. He didn’t fucking care. He wrapped a hand into your hair, using it as a bit of leverage. He was going to take out every bit of pent-up frustration on this tight cunt.

“Fuck, Slytherin!” you shrieked, the tears beginning to roll down your cheeks. He stopped immediately, his hips halting inside you. As if he was in a daze, Tom blinked rapidly and shook his head a bit. It felt as though he had been under a spell, the way he had been fucking into you.

“Fuck, I’m sorry,” he whispered. He gently pulled himself out of you, a pitiful whine leaving your lips. “I’m sorry, I’m sorry…”

Hearing him say those words alone was enough to convince him how serious the situation was. Tom didn’t say sorry unless it was to a professor or to generally get someone off of his back. Usually, it was fake. This time, it wasn’t, and it rushed out of his lips before he could stop it.

He gently wrapped himself around you, slowly turning you and laying you back against his pillows. He kicked his pants down the rest of his legs and slipped the both of you beneath his comforter.

The cool green satin pressed softly against your hot skin, softly soothing it. He laid himself down behind you, his soft breath barely tickling the hairs on the back of your neck. Hesitantly, his hand slid over your stomach. It seemed as though he wasn’t sure exactly how to comfort you, but was trying his best.

“Darling?” he whispered against your back.

“I’m sorry, I just—”

“Don’t ever apologize to me,” he said. “I’m sorry that I…I shouldn’t have been so rough with you.”

A soft sigh left you. You’d never had to use your safe word with Tom before—had never even wanted to. Every aspect of the way Tom fucked had always intrigued you. The ways he handled you as if you were nothing to him but an outlet for his pleasure, the way he insisted on doing everything, the way he was genuinely concerned about your pleasure, despite himself. It often left you breathless.

Tonight, however, had been different. You felt less than you usually did when beneath him. Usually it was a nice feeling; like you were smaller, something for him to take care of. But tonight you’d felt pure hatred coursing through his body. You were scared that it was directed toward you.

“It’s not that, Tom,” you sighed. “I was worried that you were angry with me.”

His hands gently wrapped around you and helped you to turn toward him. His eyes watched you sternly. He wanted to put any affection that had built up inside him completely into you.

“I have never been angry with you—I was angry with my worthless fucking followers, always insisting they ruin my life in the most embarrassing ways possible.”

“Why would they do that?” You gasped, shocked that they’d even think of doing such a thing.

“They think that they’re helping or something,” he scoffed, jaw clenching. You could feel the anger radiating off of him.

“I’m so sorry,” you sigh, slipping your eyes shut. “I hope I didn’t upset you further—it was just a bit too much, I suppose.”

He nods understandingly, saying nothing more. The quiet and safety you felt when with Tom had you falling into a particularly deep sleep. Though you tried to fight it off, you could feel Tom’s eyes on you, watching as you slowly drifted off.

The last thing you remembered before slipping fully into sleep was Tom’s hand gently against your cheek, his cold thumb caressing a hair away from your face.

Batch gradient descent

#Batch gradient descent update

UpGrad provides a PG Diploma in Machine Learning and AI and a Master of Science in Machine Learning & AI that may guide you toward building a career. One important factor to keep in mind is choosing the right learning rate for your gradient descent algorithm for optimal prediction. You get to know the role of gradient descent in optimizing a machine learning algorithm. Less passes: Usually, the stochastic gradient descent algorithm doesn’t need more than 10 passes to find the best coefficients.Ĭheck out: 25 Machine Learning Interview Questions & Answers Wrapping up.Rescale inputs: The gradient descent algorithm will minimize the cost function faster if all the input variables are rescaled to the same range, such as or.You need to try and see which value works best for you. Learning rate: The learning rate is very low and is often selected as 0.01 or 0.001.If you see the cost to remain unchanged, try updating the learning rate. Map cost versus time: Plotting the cost with respect to time helps you visualize whether the cost is decreasing or not after each iteration.Machine Learning with R: Everything You Need to Knowīest Practices for Gradient Descent Algorithm Top 7 Trends in Artificial Intelligence & Machine Learning Permutation vs Combination: Difference between Permutation and Combination Robotics Engineer Salary in India : All RolesĪ Day in the Life of a Machine Learning Engineer: What do they do? In stochastic gradient descent, the coefficients are updated for each training instance and not at the end of the batch of instances. You can use the stochastic gradient descent in these conditions where the dataset is huge. In these cases, batch gradient descent will take a long time to compute as one iteration needs a prediction for each instance in the training set. In some cases, the training set can be very large. One batch is referred to as one iteration of the algorithm, and this form is known as batch gradient descent. The cost function is computed over the entire training dataset for every iteration. Source Variants of Gradient Descent Algorithm Batch Gradient Descentīatch gradient descent is one of the most used variants of the gradient descent algorithm. On the contrary, a very low learning rate can help you reach the global minima, but the convergence is very slow, taking many iterations. Selecting a very high learning rate can overshoot the global minima. The selection of the learning rate is important. This process is repeated until the cost function becomes 0 or very close to 0.You need to make sure that this learning rate is not too high nor too low.Ĭoefficient = coefficient – (alpha * del) A learning rate (alpha) can be selected to control how much these coefficients will change in each iteration.

#Batch gradient descent update

After knowing the direction of downhill from the slope, you update the coefficient values accordingly.

The direction should be such that you get a lower cost(error) in the next iteration. Calculating the slope will help you to figure out the direction to move the coefficient values.

We know from the concept of calculus that the derivative of a function is the slope of the function.

The cost function is calculated by putting this value of the coefficient in the function.

The calculation of gradient descent begins with the initial values of coefficients for the function being set as 0 or a small random value. Read: Boosting in Machine Learning: What is, Functions, Types & Features Gradient Descent Algorithm- Methodology However, these bottoms may not be the lowest points and are known as local minima. Depending on the start position of the ball, it may rest on many bottoms of the valley. You want the ball to reach the bottom of the valley, where the bottom of the valley represents the least cost function. The valley is the plot for the cost function here. You can imagine gradient descent as a ball rolling down a valley. This step is repeated until the best coefficients are found. Different values are used as the coefficients to calculate the cost function. The bottom of the bowl is the best coefficient for which the cost function is minimum. This bowl is the plot for the cost function. Suppose you have a large bowl similar to something you’ve your fruit in. Source The intuition behind the Gradient Descent algorithm The point at which cost function is minimum is known as global minima. Gradient descent is one such optimization algorithm used to find the coefficients of a function to reduce the cost function. To achieve this goal, you need to find the required parameters during the training of your model. The goal is to reduce the cost function so that the model is accurate.
