🚀 Introducing zeroCPR: An Approach to Finding Complementary Products 🛍️ zeroCPR Framework - A zero-shot complementary product recommender designed to find complementary products even with limited data. - It leverages large language models (LLMs) to generate a list of potential complementary products based on the user's available product list and a reference product. 🔍 Core Mechanism - Utilizes vector search to match LLM-generated products with actual products in the dataset. 📊 Chain-of-DataFrame Technology - Developed by Mazzeschi, this technique enhances matching accuracy by allowing LLM to reason for each sample and output a score (0 or 1) to select the correct complementary products. - Outputs are directly converted into pandas data frames for easy analysis and processing. 🔄 Recent Substitute Filling - To address recommendation gaps due to insufficient data, zeroCPR uses a strategy of finding k substitutes for each complementary product, expanding the recommendation pool and enriching the user experience. 💼 Implementation and Application - The goal of the zeroCPR framework is to enable even emerging businesses with limited data to access and utilize enterprise-grade recommendation technology. #AI #ML #zeroCPR #ComplementaryProducts #DataScience #RecommenderSystems #LLMs #TechInnovation #BusinessSolutions

🚀 Sampling from Multivariate Distributions: From Statistical to Generative Models 🔗 Bridging Classic Statistical Methods and Generative AI - The importance of multivariate distribution sampling lies in understanding data dependencies, performing statistical inference, and quantifying data uncertainty across various fields. 📊 Overview of Sampling Methods 1. Kernel Density Estimation (KDE) - Smooths data points with kernel functions to estimate the multivariate density function. 2. Copula Methods - Simulates dependencies between variables to generate new samples. 3. Variational Autoencoders (VAE) - Uses an encoder and decoder to generate data in latent space. 4. Generative Adversarial Networks (GAN) - Trains a generator and discriminator adversarially to produce samples. 5. Diffusion Models - Adds noise to data and then predicts the noise in reverse to generate samples. 🧪 Data Experiments - Performance evaluation of these methods on two synthetic datasets: a standard multivariate Gaussian distribution and a complex nonlinear distribution. 🔍 Detailed Findings 1. KDE - Gaussian KDE model shows slight underfitting, especially with complex dependencies in non-standard distributions. 2. Copula Methods - Performs well for standard distributions but struggles with highly nonlinear dependencies in non-standard distributions. 3. VAE - Generally models data well. The experiment used a VAE with a two-layer fully connected neural network, showing reasonable performance. 4. GAN - Similar performance to VAE. The experiment utilized a GAN with a three-layer fully connected generator and discriminator, generating samples similar to the original data distribution. 5. Diffusion Models - Captures all dependencies but shows limitations in sample variety. The generated samples lack diversity, indicating a need for further model tuning. #AI #GenerativeModels #MultivariateDistributions #KDE #Copula #VAE #GAN #DiffusionModels #DataScience #MachineLearning #StatisticalMethods #TechInnovation
