Using conditional probability as an estimate in a loss function

I have a rather large ML framework that takes multiple conditional probability terms that are computed via classifiers/neural networks. This arbitrary loss function is computed via a function: loss_value = arbitrary_loss(probability1, probability2, ..., P(Y|Z)) I wish to have an end-to-end framework that computes everything and trains everything together. So I do not want to have an independently trained classifier. Say at some point I develop some intermediate values (embeddings) Z from the input samples X. I wish to model the conditional probability P(Y|Z) via an MLP softmax layer. This term P(Y|Z) is then estimated and plugged into the final loss which is the sum and product of other probabilities. P(Y|Z) = MLP(input_Z) #probability given input Z over labels My issue is that if I simply take the value of the softmax layer to estimate this probability and plug it in, at no point are the true labels taken into account for a supervised machine learning problem. How can I fix this without modifying the final loss function? TLDR: I need a probability term P(Y|Z) modeled via an MLP softmax layer to be used in a complex arbitrary loss function. How do i ensure this term is accurate via the true label values, so that it can be used in the final loss?

Understanding Empirical Bayes

I am trying to understand the basics of empirical bayes. I found myself struggling a lot to understand this so I tried to create a toy example involving the estimation of the success probabilities for a coin. 1) Traditional Bayesian Analysis (Beta-Binomial Conjugacy): Consider a sequence of $n$ coin tosses where we observe $X$ heads. The likelihood of observing $X$ heads given the true probability of heads $\theta$ is binomial: $$ P(X|\theta) = \binom{n}{X} \theta^X (1-\theta)^{n-X} $$ Chose a Beta prior distribution for the probability of heads $\theta$ : $$ P(\theta) = \text{Beta}(\alpha, \beta) = \frac{\theta^{\alpha-1} (1-\theta)^{\beta-1}}{B(\alpha, \beta)} $$ Using Bayes' theorem, the posterior distribution is proportional to the likelihood times the prior: $$ P(\theta|X) \propto P(X|\theta) P(\theta) $$ Substituting the binomial likelihood and the Beta prior, we get: $$ P(\theta|X) \propto \theta^X (1-\theta)^{n-X} \cdot \theta^{\alpha-1} (1-\theta)^{\beta-1} $$ $$ P(\theta|X) \propto \theta^{X+\alpha-1} (1-\theta)^{n-X+\beta-1} $$ Thus, the posterior distribution is also a Beta distribution: $$ P(\theta|X) = \text{Beta}(X + \alpha, n - X + \beta) $$ 2) Empirical Bayes: It seems like in Empirical Bayes, the parameters of the priors are estimated from the data instead of being chosen before hand. To me it makes more sense to use Method of Moments (instead of MLE) to estimate the parameters $\alpha$ and $\beta$ of the Beta prior. The sample mean $\hat{\theta}$ and sampl…

What's the relation between Generalized Policy Iteration (GPI), Actor-Critic, and Q-learning methods?

It seems to me that Generalized Policy Iteration (GPI) and Actor-Critic are the same, and Q-learning methods are a separate family of algorithms. I think both GPI and Actor-Critic describe the iterative process of policy evaluation (critic) and policy improvement (actor), while Q-learning is only bootstrapping using the Bellman optimality equation. To elaborate on my understanding: Policy evaluation (critic) is done via Monte-Carlo or temporal difference methods, including function approximation if necessary, and policy improvement (actor) can be done by being greedy (tabular case) or using the policy gradient theorem (large state space). Q-learning is not doing any of these. It's just trying to estimate the $Q^\ast$ using the Bellman optimality equation by iteratively fitting the Bellman optimality equation for Q value. I would appreciate it if anyone can confirm whether my understanding is correct or give a more systematic/precise summary of the taxonomy of online RL algorithms.

Extrinsic Hallucinations in LLMs

Hallucination in large language models usually refers to the model generating unfaithful, fabricated, inconsistent, or nonsensical content. As a term, hallucination has been somewhat generalized to cases when the model makes mistakes. Here, I would like to narrow down the problem of hallucination to cases where the model output is fabricated and not grounded by either the provided context or world knowledge. There are two types of hallucination: In-context hallucination: The model output should be consistent with the source content in context. Extrinsic hallucination: The model output should be grounded by the pre-training dataset. However, given the size of the pre-training dataset, it is too expensive to retrieve and identify conflicts per generation. If we consider the pre-training data corpus as a proxy for world knowledge, we essentially try to ensure the model output is factual and verifiable by external world knowledge. Equally importantly, when the model does not know about a fact, it should say so. This post focuses on extrinsic hallucination. To avoid hallucination, LLMs need to be (1) factual and (2) acknowledge not knowing the answer when applicable.

Predicting Values with Bayesian Neural Network

I want to use a Bayesian Neural Network for a regression task. To do that I converted a BNN from this paper to Python 3. The provided training script runs and I receive a pickle file, which I want to use to predict a value for my regression. Event though the loss for the training doesn't really go down, but this seems also be the case for the models used in the paper. The input of my network is a vector with 59 features, where one feature is my target variable. It's pretty similar to the boston housing dataset. The MLP inside the BNN returns two vales: $\mu$ and $\sigma$ . If I understand BNNs correctly $\mu$ and $\sigma$ refer to the mean and standard deviation of my input and I should use $\mu$ to predict my values. But when I use input vector I always receive a value that is roughly around the mean of my target variable. So lets say the mean is 62. When I insert a vector from my test set, that should return the target variable 142, I will get 61. When I do the same with a vector, that should return 21, I will get 63. So my predicted values are always around the mean of the target variable. What do I have to do, to get real predictions from my input data? I never worked with BNNs before and it's quite hard to find any resources on how I should model my network. Maybe someone has a nice tutorial to learn how I can use this model to predict my target variable. I have to use this class and can't use Pyro or any other framework currently, because otherwise I can't use the othe…

How to actually use the Empirical Influence Function for BCa Bootstrap Intervals?

In the course of seeking reassurance for another part of a hobby analysis* I found a stack answer which mentioned The Jackknife, the Bootstrap and Other Resampling Plans (Efron, 1980). Having managed to find the paper online, the bit about non-parametric bias and skew adjustments to the bounds of bootstrap CIs caught my eye. The problem is that I don't really understand how to do it as described in that paper . Efron (1980) as I am reading it suggests that the core ingredients of the BCa CI method are the $U_i$ and $a$ values. The derivation of the latter is simple given you know the $U_i$ with formula (pg. 21): $$ a \doteq \frac{1}{6}\frac{\sum\limits_{i=0}^n U_i^3}{\left( \sum\limits_{i=0}^n U_i^2 \right)^{\frac{3}{2}}} $$ The $U_i$ have a more complicated formula, coming from what's termed the empirical influence function (also pg. 21): It is this formula for the $U_i$ that I don't know how to work with. Clicking around in some more stack questions, I found a reference to Bootstrap Methods and their Application (Davison and Hinkley, 1997) but I couldn't find that online. Nevertheless, I did find a slideshow by Davison on ResearchGate based on it which proposes that the $a$ value can be jackknifed like so (I've changed the subscript $j$ to $i$ to match Efron, 1980): $$ l_i \approx l_{jack,i} = (n-1)(\hat{\theta} - \hat{\theta}_i)$$ where $n$ is the number of observations in the original sample. I have tested my understanding of the jackknife estimate of $a$ against the $U_…

How are perplexities over multiple instance aggregated?

The perplexity of the $i^{th}$ token in the $k^{th}$ sequence is $$ P_{ki} = \frac{1}{p(t_{ki})} $$ The perplexity aggregated for the $k^{th}$ sequence is then $$ P_{k} = \left(\prod_{i=1}^N P_{ki}\right)^{1/N} \\ = \left(\prod_{i=1}^N \frac{1}{p(t_{ki})} \right)^{1/N} $$ which is the geometric mean of the perplexities of the tokens. This makes sense as we are essentially taking the multiplicative inverse of the probability that the model got the whole sequence correct. Now my question is how to aggregate the perplexities of several sequences. It seems from various places, including the Hugging Face Tutorial , I see that the prescription is to take the arithmetic mean of the perplexities of sequences $$ P = \frac{1}{m} \sum_{k=1}^m P_k $$ I am not quite understanding what it means to take the average of 1/probabilities. What is this actually capturing?

Moderator Analysis in Cox Regression

Imagine an RCT with two groups with a time-to-event endpoint. The (pre-specified) strategy for analysing this trial is a Cox Regression using common covariate adjustment to reduce outcome heterogeneity. So far, so good. Now I want to know whether my treatment effect is moderated by level of education (3 levels). If I used the pre-specified cox regression with covariate adjustment and integrated the treatment*education interaction, the SEs are getting very large. What may the reasons be? Is my sample size (120 per group) too little and should I reduce the covariates for which I adjust? Edit: I controlled for 4 covariates. There were 76 events in the IG and 91 events in the CG. More specifically: Education level1: IG: 13 CG: 18. Education level2: IG: 32 CG: 28. Education level3: IG: 31 CG: 45

Would the DDPG algorithm still function effectively if some transitions stored in its replay buffer are generated by a completely unrelated policy?

Let's hypothesize a scenario where some of the records ( s i , a i , r i , s i+1 ) in the replay buffer are generated by another completely unrelated random policy. If the DDPG algorithm still samples random minibatches from this buffer for learning as usual, would the learning process proceed successfully? Actually, there's a pre-processing stage before training DDPG in my online learning application, where another module learns the safe action range. I wonder if the transition records obtained during this stage can be used to pre-train the DDPG agent.

Minimum Survey Respondents for Hypotheses I want to answer

I am an eager statistics noob, so apologies on the basic questions. I am looking to send out a survey to a population that is large (people with diabetes who take insulin in the US) (~ 8.4 million) Based on this I am aiming for 96+ survey responses overall (with a margin of error of +- 10%), with a goal of getting closer to 300 responses. I have some hypotheses I want to look at in the survey results and will be doing some statistical testing One hypothesis is "Hypothesis: There is a significant difference in rating of importance of (xyz user need, just giving a fake example - being able to quickly calculate amount of insulin for a meal) based on time the user has been using insulin" This would be a demographic question I collect (How long have you been using insulin for?), with a range of responses in months. Since importance is a rating on a likert scale (ordinal), the groups are different, and I want to understand difference, I was thinking of doing the Mann-Whitney test. I specifically would like to understand if longer time using insulin would impact rating of importance on this one user need. My question: Would I need a minimum of 96 respondents who answer in each bucket (for example 1 year or longer and 1 year or shorter) to aim for a stat sig response or would I just need to be looking at 96 overall for all respondents who answer this q. Also, if you have feedback on my approach feel free to weigh in.

Is reinforcement learning suitable for application automation?

I have basically automatised the use of an app through the use of OCR and computer vision. So basically when a word or an image is detected it will perform a certain action. When that action is successfully completed it will go to the next state. Now I want to try basically with a more "heuristic" approach and I thought about reinforcement learning. Why? Because I am aiming to build a tool that basically understand automatically what actions to perform in a certain state. But I have a doubt. Even though I don't need to declare an association like this (it would beat the purpose of deep reinforcement learning or deep learning in general): if(state.MENU_VIEW) clickManager.clickOnFolder(); ... I still need to define the states, the actions and the reward. Meaning I would need to instruct my app that when the OCR result is "Open Folder" it means the state I am in is MENU_VIEW. I simply wouldn't tell my app what action to perform in a that state. Am I correct? What I am trying to say is: how exactly could I make it so that the states (and maybe also the actions?) are generated automatically? The reward in this case scenario would be basically the folder being opened successfully.

Probability interpretation of attention mechanism in Seq2Seq

I have ready many explanations of the seq2seq model. In my opinion, however, it is really like a robot that might say something correctly, but doesn't really understand it, just as is true with an LLM generally. In my opinion, the correct way to describe Seq2Seq and similar NLP models should start from a probability view. My probability view is very simple; the output of the encoder is a representation of the probability distribution of the next word. In each step of the Decoder, it just modifies the distribution based on each word it predicted from the distribution and outputs the modified distribution. It then does this repeatedly. Assuming this probability view is correct, how could we explain the attention mechanism used in Seq2seq?

Structure and parameters of modern AI-based chess engines

I understand some recent chess engines (like AlphaZero or MuZero) are based on neural networks. This question is not specific to chess, any other game (e.g. go) would do, but I keep chess for concreteness. I am not interested in how these engines are trained but in what they "look like" after training. (For concreteness, it suffices for me that they give a "score" for a given board position.) Somewhat similar questions have been asked here but I can't find what I need. Is it correct to view them as a neural network? Or is there some other major component like search trees or other type of algorithm. I'm assuming that answer here is "yes" in an appropriate sense. Note: The AlphaZero paper talks about various forms of tree search. It is not clear to me how they are used to play, and from the appendix apparently some other engines use very limited search, like depth 2? That would be already interesting to me. What is the depth of the network? Any reference to precise parameters? What is the input and output format of these networks? Is the input just an array with pieces positions (excluding three-fold repetition rules and similar secondary issues). What is the output? Some info is here but I can't quite understand how it works specifically e.g. for chess. What activation functions are used?

Prove Wald statistic = number of linear restrictions times F statistics

I want to prove $W=(Rb-q)'(Rs^2(X'X)^{-1}R')^{-1}(Rb-q)=JF$ , where $s^2=\displaystyle{\frac{e'e}{n-k}}$ .

In a particular, probably simpler example, consider a partitioned linear regression model $Y=X_1\beta_1+X_2\beta_2+\epsilon$ , and $H_0$ : $\beta_2=0$ , so $Rb-q=b_2$ which is an OLS estimator of $\beta_2$ . $\beta_1$ is $k_1\times 1$ and $\beta_2$ is $k_2\times 1$ so $J$ should be $k_2$ .We want $k_2F=W$ .

In the paper Attention is all you need , here is Table 1, can someone explain what architecture is referred to in the "Convolution" row and hence describe the other 3 columns in it? The other ones are pretty clear, for example Recurrent, takes $O(d^2)$ operations in one time-step to multiply the hidden state with the weight matrix, and there are $n$ such time-steps, which need to be done sequentially ( $O(n)$ ), also making the information from the first and last tokens in the sentence to travel $O(n)$ steps. For Self-attention, every word in the sentence, attends to every other, so $O(n^2)$ pairs, dot product attention taking $O(d)$ operations. Clearly, the path length is $O(1)$ and there are no sequential operation, all these $O(n^2)$ pairs can be computed independently. The "Convolution" row is not clear to me!

Why some papers focus on constructing large dataset from real robots, instead of simulations?

Recently, I have seen papers about large datasets for robotics such as DROID( https://droid-dataset.github.io/ ) or Open X-Embodiment( https://robotics-transformer-x.github.io/ ). As I see, the datasets are specific to some types of robots(although X-Embodiment allows one robot to learn from another robot's data) and environments. If one wants to add another robot into the dataset, they have to do all data sampling again, which is quite expensive. Some environments might be difficult to reproduce, especially as they collected data from all the labs in the world. I am wondering: why don't they instead set up data collection procedure on simulation? it will make the data collection way cheaper. When they want to add a new robot and collect data with the same tasks and environments like other robots, they can do it easily. It is also easy to add a new task and collect data from all robots/environments. Then, why they collect data in real world while giving up on such reproducibility/extensibility? Is Sim2Real that bad, even if it can collect way more samples easily?

Measuring personal growth

My founder friends constantly think about growth. They think about how to measure their business growth and how to get to the next order of magnitude scale. If they’re making $1M ARR today, they think about how to get to $10M ARR. If they have 1,000 users today, they think about how to get to 10,000 users. This made me wonder if/how people are measuring personal growth. I don’t want to use metrics like net worth or the number of followers, because that’s not what I live for.

Diffusion Models for Video Generation

Diffusion models have demonstrated strong results on image synthesis in past years. Now the research community has started working on a harder task—using it for video generation. The task itself is a superset of the image case, since an image is a video of 1 frame, and it is much more challenging because: It has extra requirements on temporal consistency across frames in time, which naturally demands more world knowledge to be encoded into the model. In comparison to text or images, it is more difficult to collect large amounts of high-quality, high-dimensional video data, let along text-video pairs. 🥑 Required Pre-read: Please make sure you have read the previous blog on “What are Diffusion Models?” for image generation before continue here.
