- [ ] run probe on some data
- [ ] add a mlp one too
- [ ] try some alternative with updating a copy of weights to get alt score and hidden states!
- [ ] try to work out why so much mem?!
- oh it's def the graph. just huge! from 7-9g to 25g even with bfloat16
- with or without tracedict
not much I can do
what if I, instead of -probs. I switch yes and no!
OK it hard to find a counterfactual one.. A single up date can go to far. And we can enter degenater cases like ones that say
> negativenegativenegativenegativenegative
But I've also found good ones. Hmm
My current hypothesis:
- It would be nice to compare a pair of counterfactual samples, but this presents difficulties. These are, firstly it's time consuming to produce a counterfactual. Secondly this might give away which the true one is, and the counterfacual might be obviously synthetic is if stands out in someway
- Instead I will give the probe the weigths updates that backprop predicts. That is, the gradients to go from the current prediction to the opposite predict. Sure this will sometimes update to much and so on but I leave that to the probe to sort out. This gradient information may be usefull to the probe as it shows which weights were important, and in which direction.
- So if a "truth neuron" is important then it's gradient will be large. And perhaps the gradient direction will show a direction of truth or lie.
- I can either try the gradient on the weights (low dimensional but less info) or the gradient on the outputs (more relevent, but it must be gradients on a much more variable landscape
Now this whole thing uses a lot of memory. Lets see if I can do it with the 3B model. But potentially I can fix this by note backpropogating all the way back through ~600 tokens. Can I just do the last few tokens? Or even the last one? I might be able to do that by specifying the inputs.. although they are not the tokens!
I can probobly pass in input embeds fddirectoy
ok... no even if I do that, it still uses just as much memory....
maybe I can parse all but the last token, then just do the next token based on detached hidden states?
```py
# create position_ids on the fly for batch generation
position_ids = attention_mask.long().cumsum(-1) - 1
position_ids.masked_fill_(attention_mask == 0, 1)
inputs_embeds = self.wte(input_ids)
position_embeds = self.wpe(position_ids)
```

try to improve data loading
- improve prompt stuff meh didn't help! Maybe I can make it iterative
tried to improve memory
- only doing part of the rollout with grad... this is not how transformers work, hidden state doesn't seem to passed along iteratively. I should have know.
- tried specifying inptus to grad as only input_embeds, or part of them. Neither freeds memory or even was able to update the weights!
- [ ] try freezing some weights?
- **OH backprop to the embedding weights worked where the input_embed diddn't :star:!** e.g. this gives a bit less mem used
except it does seem to use more mem after a few?
```py
inputs_embeds = model.transformer.wte(input_ids)
outputs = model(inputs_embeds=inputs_embeds)
loss = calc_loss(outputs)
loss.backward(inputs=model.transformer.wte.weight)
```
## Where am I up to?
well I've given up on improving the memory for now. I'd like to look up more on counterfactual examples, but it doesn't feel prospective.
I would like to get a big grad dataset and try a probe to see if I can go from the linear probe acc of 80% to 95%.
I would also like to work out which parts I need to save to get a good prediction. Is it the head activations. Only the grads? Or the MLP. Knowing this will save me momory
# 2023-09-10 12:22:25
hmm looks at this, in they use torch.autograd to backpropr to noise on the embeddings https://github.com/microsoft/KEAR/blob/7376a3d190e5c04d5da9b99873abe621ae562edf/model/perturbation.py#L60

wow I got 96% wit ha lienar prob and head_activation_and_grad !!

Here\\'s yet another blasphemous European story in which they blast the religion of their country. (These atheist filmmakers are relentless.) Here we see a brutal blasting of Catholics and/or the Catholic clergy (and I am not Catholic).<br /><br />This won actually won an Academy Award for bes foreign film. That\\'s probably because the story made Catholics and religious belief in general look extremely weak. One of the main characters is a priest and he cares more about food than anything else. He\\'s portrayed as nothing but an idiot. No wonder the secular- dominated Academy loved this movie.<br /><br />Also, there is some overacting fool who plays a guy who renounces his religion so he can marry one of the four daughters featured in the story. The daughters take turns seducing the \"seminary\" student (who states he studied for six years but says he\\'s an agnostic!). I mean, how blasphemous IS this film??!!!<br /><br />This is a disgrace and another excellent example of the secular-progressive bigotry of the film business, worldwide (not just Hollywood).\\n\\n\\n\\n### Response:\\npositive\\n\\n### Instruction\\nThe following movie review expresses what sentiment?

The original Prom Night, while not in my humble estimation a masterpiece, still realized what it was... horror. There are some simple things to remember when making a horror film. Suspense is crucial to maintaining the interest of the audience. Sorry folks, but a white knuckle film this was not! The scares were cheap, and foreshadowed terribly. (A good example of scare which has been done to clichéd excess now, is the cat jumping out of the closet, followed soon there after but a now unexpected appearance by the villain of the film) This film couldn\\'t successfully pull that off, so how could I expect it to fulfill any of the other conventions of horror film. There needs to be a likable hero or heroine. This film doesn\\'t have one. The person I most identified with was the head detective. His calm demeanor, but level headed approach to the escape of a killer was what more films of this ilk should have. Common sense approach to events that occur. (If you\\'re running from an Axe wielding psycho, you turn and sprint in the opposite direction. Not jog, whilst looking back ever three seconds, gaging the killer\\'s progress, only to trip over every branch and inanimate object in your path.) If you friend disappears, you don\\'t go looking for them alone. And if you suspect foul play you tell someone, not investigate yourself. These clichés are tired and well overplayed. In the horror genre in general, and in this film in particular. \\'\\'\\'\\n\\nBetween 0 and 1, which is the sentiment of this example?\\n\\n\\n### Response:\\n0\\n\\n### Instruction\\nConsider the following example: \\'\\'\\' Viggo Mortensen stars as a new inmate of a haunted prison in which the warden (Played well by Lane Smith) has a grisly secret that could be the reason why various prison guards and inmates are being slaughtered by a supernatural presence. Lincoln Kilpatrick is the lifer who knows the secret and is scared for his life. When I think prison movies, I always think action movies starring Stallone or Van Damme or high caliber dramas such as Shawshank Redemption or The Green Mile. However I didn\\'t expect a ghost story more along the lines of Exorcist III. Prison however is an atmospheric effort and it certainly remains the best movie of Renny Harlin\\'s career. The movie is creepy and has some good acting from a cast of (at the time) unknowns. Lane Smith comes off the best because his warden isn\\'t the usual cliché of evil personified but rather nervous and twitchy which adds some credibility to a movie that far exceeds expectations.<br /><br />*** out of 4-(Good) \\'\\'\\'\\n\\nBetween 0 and 1, which is the sentiment of this example?\\n\\n\\n### Response:\\n1\\n\\n### Instruction\\nConsider the following example: \\'\\'\\' really awful... lead actor did OK... the film, plot etc was completely crap and inaccurate it may as well have been a sequel to well... anything it had little or no relevance to Carlitos Way... and should be avoided like the plague by any Carlito\\'s ways fans... no mention of Gail in fact he ends up with some other bird, no mention of Klienfelt, no mention of how he got caught, no mention of how he ended up in jail... they attempted to make it like the original with flash backs at the beginning... but to be honest when rating it I was looking for a zero mark... unfortunately I had to rate it higher...<br /><br />Its a terrible attempt to cash in on what was one of the best films of the 90\\'s... overall it was approximately £6 and 2 hours of my life wasted... for all the \"action\" in it, it was truly boring slow and predictable... again to any Carltio\\'s Way fans avoid this fiasco... \\'\\'\\'\\n\\nBetween 0 and 1, which is the sentiment of this example?\\n\\n\\n### Response:\\n',\n",
