Latest Research on Ising Models part6(Machine Learning 2024)
- The Griffiths phase in systems with quenched disorder occurs below the ordering transition of the pure system down to the ordering transition of the actual disordered system.
- Large fluctuations in the disorder degrees of freedom result in exponentially rare, long-range ordered states and broad distributions in response functions.
- A large-deviations Monte Carlo algorithm is used to extract the exponential tail of the magnetic susceptibility distribution in the two-dimensional bond-diluted Ising model.
- The behavior of the susceptibility distribution is studied across the full phase diagram, revealing differences and similarities between cases and demonstrating a connection between the fraction of ferromagnetic bonds and the size of the magnetic susceptibility.

Predicting Bank Customer Churn with Machine Learning
- This project aims to predict bank customer churn using machine learning techniques.
- The dataset used in this project was sourced from Kaggle and comprised 10,000 rows with 14 columns.
- Exploratory data analysis was performed to visualize data distributions and correlations between variables.
- Irrelevant columns were dropped, and one-hot encoding was used to convert categorical data into numerical form.
- SMOTE was applied to handle imbalanced data by generating synthetic samples for the minority class to balance the dataset.
- Six different models were evaluated on the customer churn prediction dataset, and the best performing model was Random Forest Classifier.
- A Graphical User Interface (GUI) was built, and the project successfully developed a Random Forest Classifier model to predict customer churn with an accuracy of 86.22%.
- The model provides actionable insights to help businesses reduce churn rates and retain valuable customers.
- Before saving the model, it’s a good practice to retrain it on the entire resampled dataset to ensure the model has learned from all the available data.
- Once the best-performing model has been identified, the model can be saved to disk to use again later without needing to retrain it.

Latest Research on Ising Models part4(Machine Learning 2024)
- A research study investigates the effect of noise on the transition probabilities of the Landau-Zener model in the one-dimensional transverse field Ising model.
- The analysis reveals that under small noise conditions, the model follows an anti-Kibble-Zurek scaling.
- As the noise increases, a new scaling behavior emerges, showing higher accuracy than previously reported.
- The study also identifies parameters that optimize the defect density based on the new scaling, allowing for the refinement of optimized parameters with greater precision.

- This research focuses on studying a higher-order Painlevé-type equation that arises as a string equation of the 3rd order reduction of the KP hierarchy.
- The equation describes the Ising phase transition coupled to 2D gravity and is characterized in terms of isomonodromic deformations of a rational connection on P1.
- The (nonautonomous) Hamiltonian structure associated with this equation is identified and a suitable τ-differential is written for the system, allowing the verification of certain conjectures.
- A general formula for the τ-differential of a special class of resonant connections is also presented.

Latest Research on Ising Models part2(Machine Learning 2024)
- Researchers have conducted a study on the classical Glauber dynamics for sampling from Ising models with sparse random interactions.
- The study focuses on the Viana — Bray spin glass, where the interactions are supported on the Erdős — Rényi random graph G(n,d/n) and randomly assigned ±β.
- The researchers prove that Glauber dynamics mixes in n1+o(1) time with high probability as long as β≤O(1/d−−√).
- The study also extends its results to random graphs drawn according to the 2-community stochastic block model and the inference problem in community detection.

New updates on Gibbs sampling part6(Machine Learning future)
- We present two novel algorithms for simulated tempering simulations that break detailed balance condition (DBC) but satisfy the skewed detailed balance.
- The irreversible methods are based on Gibbs sampling and focus on breaking DBC at the update scheme of temperature swaps.
- Tests conducted on different systems, including a simple system, the Ising model, and MD simulations on Alanine pentapeptide (ALA5), demonstrate improved sampling efficiency compared to conventional Gibbs sampling and simulated tempering with Metropolis-Hastings (MH) scheme.
- The algorithms are particularly advantageous for simulations of large systems with many temperature ladders and can be easily adapted for other dynamical variables to flatten rugged free energy landscapes.

Ridge Regression: Step by step introduction with example
- Ridge regression is a variation of linear regression, specifically designed to address multicollinearity in the dataset.
- Ridge regression introduces a regularization term that penalizes large coefficients, helping to stabilize the model and prevent overfitting.
- The shrinkage penalty in ridge regression refers to the regularization term added to the linear regression equation to prevent overfitting and address multicollinearity.
- To this, a penalty term is added, which is proportional to the square of the magnitude of the coefficients.
- Ridge regression proves valuable in improving the robustness and performance of linear regression models, especially in situations with multicollinearity.
- Scaling predictors matters; before applying ridge regression, predictors are standardized to be on the same scale.
- Ridge regression introduces a regularization parameter, denoted as 𝜆, which controls the extent of shrinkage applied to the regression coefficients.
- As the value of 𝜆 increases, the model’s flexibility in fitting the data diminishes.
- The superiority of ridge regression compared to the method of least squares arises from the inherent trade-off between variance and bias.
- To build a ridge regression model essentially means to find the coefficients, and the intercept term does not get affected by the shrinkage penalty.
