Machine Learning (ML) is the branch of Artificial Intelligence in which we use algorithms to learn from data provided to make predictions on unseen data. Recently, the demand for Machine Learning engineers has rapidly grown across healthcare, Finance, e-commerce, etc. According to Glassdoor, the median ML Engineer Salary is $131,290 per annum. In 2021, the global ML market was valued at $15.44 billion. It is expected to grow at a significant compound annual growth rate (CAGR) above 38% until 2029.

Reviewer's response to the rebuttal "line 308: [10, 400] range for alpha We chose 400 because higher values of alpha caused computational difficulties in the Gibbs sampling. This upper bound is a bit arbitrary; however, we found the exact upper limit above about 100 had little effect on the estimates of transition probabilities. Similarly, adjusting the lower bound below 60 or so had little effect. While we do hope for a more well justified hyperprior for alpha in future work, we believe our choice did not overly influence the results." Please add this information to the paper.

"Reciprocally Coupled Local Estimators Implement Bayesian Information Integration Distributively" puts forward a new take on Bayesian integration of multimodal cues. Instead of assuming a special area in the brain, where evidence from various sensory cues is combined (as in Ma and all, 2006), the authors consider a scenario, whereby each area receiving direct afferent input from a single modality (i.e. In the example analysed by the authors, and under a number of suitable assumptions, the cue integration they observe in their networks is close to Bayes-optimal. Building up on work of Fung and all (2010), the authors derive theoretical predictions for the integration of information in reciprocally coupled ring attractors (CANNs), which they also confirm by simulations. The reader is led through the general steps of the analysis, while details are provided in the supplementary material.

This paper introduces a method for finding Bayesian networks for continuous variables in high-dimensional spaces. The paper assumes a Gaussian distribution of any particular random variable when conditioned on its parent nodes. A LASSO objective function is used to construct a sparse set of parent nodes for each random variable, subject to an additional constraint that the resulting structure be an acyclic graph. The network structure constraint is framed as an ordering problem, and an A* search algorithm is proposed which finds a directed acyclic graph which maximizes the LASSO objective function. The LASSO objective function, minus the DAG constraint, is used as an admissible heuristic in the A* search.

First provide a summary of the paper, and then address the following criteria: Quality, clarity, originality and significance. This paper proposes a novel model selection criterion for binary latent feature models. It is like variational Bayes, except that rather than assuming a factorized posterior over latent variables and parameters, it approximately integrates out the parameters using the BIC. They demonstrate improved held-out likelihood scores compared to several existing IBP implementations. The proposed approach seems like a reasonable thing to do, and is motivated by a plausible asymptotic argument.

First provide a summary of the paper, and then address the following criteria: Quality, clarity, originality and significance. The bottom line of this paper is an efficient algorithm for finding maximum likelihood estimators for elliptically contoured distributions, a class of densities that includes the Gaussian and various generalizations of it. For the Gaussian itself, that optimization is straightforward, it's the generalizations where the new algorithm provides real advantages. One could argue that this focus on a relatively arcane family of distributions (Kotz-type) limits the utility of this paper. But I think it's actually the other way round: The paper may spark new interest at NIPS in these models.

First provide a summary of the paper, and then address the following criteria: Quality, clarity, originality and significance. This paper presents a Bayesian approach to state and parameter estimation in nonlinear state-space models, while also learning the transition dynamics through the use of a Gaussian process (GP) prior. The inference mechanism is based on particle Markov chain Monte Carlo (PMCMC) with the recently-introduced idea of ancestor sampling. The paper also discusses computational efficiencies to be had with respect to sparsity and low-rank Cholesky updates. This is a technically sound and strong paper with clear and accessible presentation.

Bayesian inference is a way to get sharper predictions from your data. It's particularly useful when you don't have as much data as you would like and want to juice every last bit of predictive strength from it. Although it is sometimes described with reverence, Bayesian inference isn't magic or mystical. And even though the math under the hood can get dense, the concepts behind it are completely accessible. In brief, Bayesian inference lets you draw stronger conclusions from your data by folding in what you already know about the answer. Bayesian inference is based on the ideas of Thomas Bayes, a nonconformist Presbyterian minister in London about 300 years ago. He wrote two books, one on theology, and one on probability. His work included his now famous Bayes Theorem in raw form, which has since been applied to the problem of inference, the technical term for educated guessing. The popularity of Bayes' ideas was aided immeasurably by another minister, Richard Price. He saw their significance, refined them and published them. It would be more accurate and historically just to call Bayes' Theorem the Bayes-Price Rule.

The paper introduces probabilistic principal component analysis on Riemannian manifolds, extending earlier non-probabilistic versions to a probabilistic latent variable model, and derives maximum likelihood estimation procedures for a broad class of manifolds. The methods are demonstrated on toy data (maniold is a sphere) and shape analysis on images. This is a very interesting advancement, and the paper is well written, making it reasonably accessible in spite of the difficult topic. I have a set of interrelated questions; explicating and clarifying them would clarify the potential impact of the paper to the reader: - Is essential generality lost by assuming an Euclidean latent space? Locally on a tangent space it makes sense, and may be practically necessary, of course.

REVIEWER 5: Yes, clarifying that we assume chordality is useful, and will revise the title, abstract and elsewhere to emphasize this assumption. REVIEWER 6: The reviewer's summary of the proof of Lemma 4 about the balancing condition is accurate. We may have been a bit pedantic in spelling out the details of the proof, but on the other hand, simply saying that the balancing condition "obviously" holds because of the running intersection property would not be very informative either, and we would rather err on the side of giving too much details rather than too little. The standard Bayesian approach we use for model learning is statistically consistent for choosing the correct dimensionality, since prior distribution assigned to model parameters acts as a regularizer. This property is so widely established in the literature that we did not consider it to be necessary to emphasize the aspect in the paper.
