Identifying the strongest self-report predictors of sexual satisfaction using machine learning
Sexual satisfaction has been robustly associated with relationship and individual well-being. Previous studies have found several individual (e.g., gender, self-esteem, and attachment) and relational (e.g., relationship satisfaction, relationship length, and sexual desire) factors that predict sexual satisfaction. The aim of the present study was to identify which variables are the strongest, and the least strong, predictors of sexual satisfaction using modern machine learning. Previous research has relied primarily on traditional statistical models which are limited in their ability to estimate a large number of predictors, non-linear associations, and complex interactions. Through a machine learning algorithm, random forest (a potentially more flexible extension of decision trees), we predicted sexual satisfaction across two samples (total N = 1846; includes 754 individuals forming 377 couples). We also used a game theoretic interpretation technique, Shapley values, which allowed us to estimate the size and direction of the effect of each predictor variable on the model outcome. Findings showed that sexual satisfaction is highly predictable (48–62% of variance explained) with relationship variables (relationship satisfaction, importance of sex in relationship, romantic love, and dyadic desire) explaining the most variance in sexual satisfaction. The study highlighted important factors to focus on in future research and interventions
A machine learning approach to predicting perceived partner support from relational and individual variables
Perceiving one’s partner as supportive is considered essential for relationships, but we know little about which factors are central to predicting perceived partner support. Traditional statistical techniques are ill-equipped to compare a large number of potential predictor variables and cannot answer this question. This research used machine learning analysis (random forest with Shapley values) to identify the most salient self-report predictors of perceived partner support cross-sectionally and 6 months later. We analyzed data from five dyadic data sets (N = 550 couples) enabling us to have greater confidence in the findings and ensure generalizability. Our novel results advance the literature by showing that relationship variables and attachment avoidance are central to perceived partner support, whereas partner similarity, other individual differences, individual well-being, and demographics explain little variance in perceiving partners as supportive. The findings are crucial in constraining and further developing our theories on perceived partner support
Using Spectral and Cross-Spectral Analysis to Identify Patterns and Synchrony in Couples\u27 Sexual Desire
Sexual desire discrepancy is one of the most frequently reported sexual concerns for individuals and couples and has been shown to be negatively associated with sexual and relationship satisfaction. Sexual desire has increasingly been examined as a state-like construct that ebbs and flows, but little is known about whether there are patterns in the fluctuation of sexual desire. Utilizing spectral and cross-spectral analysis, we transformed 30 days of dyadic daily diary data for perceived levels of sexual desire for a non-clinical sample of 133 couples (266 individuals) into the frequency domain to identify shared periodic state fluctuations in sexual desire. Spectral analysis is a technique commonly used in physics and engineering that allows time series data to be analyzed for the presence of regular cycles of fluctuation. Cross-spectral analysis allows for dyadic data to be analyzed for shared rates of fluctuation between partners as well as the degree of (a)synchrony (or phase shift) between these fluctuations. Men and women were found to exhibit fluctuations in sexual desire at various frequencies including rates of once and twice per month, and to have sexual desire that was unlikely to fluctuate over periods of three days or less and therefore exhibited persistence. Similar patterns of fluctuation were exhibited within couples and these patterns were found to be largely synchronous. While instances of desire discrepancy may arise due to differences in rates of sexual desire fluctuation and random fluctuations, such instances may be normal for romantic relationships. The results have important implications for researchers, clinicians, and educators in that they corroborate the supposition that sexual desire ebbs and flows and suggest that it does so with predictable regularity
D'ya like DAGs? A Survey on Structure Learning and Causal Discovery
Causal reasoning is a crucial part of science and human intelligence. In
order to discover causal relationships from data, we need structure discovery
methods. We provide a review of background theory and a survey of methods for
structure discovery. We primarily focus on modern, continuous optimization
methods, and provide reference to further resources such as benchmark datasets
and software packages. Finally, we discuss the assumptive leap required to take
us from structure to causality.Comment: 35 page
Gated Variational AutoEncoders: Incorporating Weak Supervision to Encourage Disentanglement
Variational AutoEncoders (VAEs) provide a means to generate representational
latent embeddings. Previous research has highlighted the benefits of achieving
representations that are disentangled, particularly for downstream tasks.
However, there is some debate about how to encourage disentanglement with VAEs
and evidence indicates that existing implementations of VAEs do not achieve
disentanglement consistently. The evaluation of how well a VAE's latent space
has been disentangled is often evaluated against our subjective expectations of
which attributes should be disentangled for a given problem. Therefore, by
definition, we already have domain knowledge of what should be achieved and yet
we use unsupervised approaches to achieve it. We propose a weakly-supervised
approach that incorporates any available domain knowledge into the training
process to form a Gated-VAE. The process involves partitioning the
representational embedding and gating backpropagation. All partitions are
utilised on the forward pass but gradients are backpropagated through different
partitions according to selected image/target pairings. The approach can be
used to modify existing VAE models such as beta-VAE, InfoVAE and DIP-VAE-II.
Experiments demonstrate that using gated backpropagation, latent factors are
represented in their intended partition. The approach is applied to images of
faces for the purpose of disentangling head-pose from facial expression.
Quantitative metrics show that using Gated-VAE improves average
disentanglement, completeness and informativeness, as compared with un-gated
implementations. Qualitative assessment of latent traversals demonstrate its
disentanglement of head-pose from expression, even when only weak/noisy
supervision is available
Toward a causal link between attachment styles and mental health during the COVID-19 pandemic
Background
Recent research has shown that insecure attachment, especially attachment anxiety, is associated with poor mental health outcomes, especially during the COVID-19 pandemic. Other research suggests that insecure attachment may be linked to nonadherence to social distancing behaviours during the pandemic.
Aims
The present study aims to examine the causal links between attachment styles (secure, anxious, avoidant), mental health outcomes (depression, anxiety, loneliness) and adherence to social distancing behaviours during the first several months of the UK lockdown (between April and August 2020).
Materials & Methods
We used a nationally representative UK sample (cross-sectional n = 1325; longitudinal n = 950). The data were analysed using state-of-the-art causal discovery and targeted learning algorithms to identify causal processes.
Results
The results showed that insecure attachment styles were causally linked to poorer mental health outcomes, mediated by loneliness. Only attachment avoidance was causally linked to nonadherence to social distancing guidelines.
Discussion
Future interventions to improve mental health outcomes should focus on mitigating feelings of loneliness. Limitations include no access to pre-pandemic data and the use of categorical attachment measure.
Conclusion
Insecure attachment is a risk factor for poorer mental health outcomes
Systematic review and theoretical comparison of children's outcomes in post-separation living arrangements.
The purpose of the systematic review was to synthesize the literature on children's outcomes across different living arrangements (nuclear families, shared physical custody [SPC], lone physical custody [LPC]) by extracting and structuring relevant theoretical hypotheses (selection, instability, fewer resources, and stressful mobility) and comparing the empirical findings against these hypotheses. Following the PRISMA guidelines, the review included 39 studies conducted between January 2010-December 2022 and compared the living arrangements across five domains of children's outcomes: emotional, behavioral, relational, physical, and educational. The results showed that children's outcomes were the best in nuclear families but in 75% of the studies children in SPC arrangements had equal outcomes. Children in LPC tended to report the worst outcomes. When compared with the different theoretical hypotheses, the results were the most consistent with fewer resources hypothesis which suggests that children especially in LPC families have fewer relational and economic resources whereas children in SPC families are better able to maintain resources from both parents
Causal Effect Identification in Uncertain Causal Networks
Causal identification is at the core of the causal inference literature,
where complete algorithms have been proposed to identify causal queries of
interest. The validity of these algorithms hinges on the restrictive assumption
of having access to a correctly specified causal structure. In this work, we
study the setting where a probabilistic model of the causal structure is
available. Specifically, the edges in a causal graph exist with uncertainties
which may, for example, represent degree of belief from domain experts.
Alternatively, the uncertainty about an edge may reflect the confidence of a
particular statistical test. The question that naturally arises in this setting
is: Given such a probabilistic graph and a specific causal effect of interest,
what is the subgraph which has the highest plausibility and for which the
causal effect is identifiable? We show that answering this question reduces to
solving an NP-complete combinatorial optimization problem which we call the
edge ID problem. We propose efficient algorithms to approximate this problem
and evaluate them against both real-world networks and randomly generated
graphs.Comment: 27 pages, 9 figures, NeurIPS 2023 conference, causal identification,
