Linguacodus: A Synergistic Framework for Transformative Code Generation in Machine Learning Pipelines

In the ever-evolving landscape of machine learning, seamless translation of natural language descriptions into executable code remains a formidable challenge. This paper introduces Linguacodus, an innovative framework designed to tackle this challenge by deploying a dynamic pipeline that iteratively transforms natural language task descriptions into code through high-level data-shaping instructions. The core of Linguacodus is a fine-tuned large language model (LLM), empowered to evaluate diverse solutions for various problems and select the most fitting one for a given task. This paper details the fine-tuning process, and sheds light on how natural language descriptions can be translated into functional code. Linguacodus represents a substantial leap towards automated code generation, effectively bridging the gap between task descriptions and executable code. It holds great promise for advancing machine learning applications across diverse domains. Additionally, we propose an algorithm capable of transforming a natural description of an ML task into code with minimal human interaction. In extensive experiments on a vast machine learning code dataset originating from Kaggle, we showcase the effectiveness of Linguacodus. The investigations highlight its potential applications across diverse domains, emphasizing its impact on applied machine learning in various scientific fields.

Segmentation of EM showers for neutrino experiments with deep graph neural networks

We introduce a novel method for showers reconstruction from the data collected with electromagnetic (EM) sampling calorimeters. Such detectors are widely used in High Energy Physics to measure the energy and kinematics of in-going particles. In this work, we consider the case when a large number of particles pass through an Emulsion Cloud Chamber (ECC) brick, generating electromagnetic showers. This situation can be observed with long exposure times or large input particle flux. For example, SHiP experiment is planning to use emulsion detectors for dark matter search and neutrino physics investigation. The expected full flux of SHiP experiment is about $10^{20}$ particles over five years. Because of the high amount of in-going particles, we will observe a lot of overlapping showers. It makes EM showers reconstruction a challenging segmentation problem. Our reconstruction pipeline consists of a Graph Neural Network that predicts an adjacency matrix for the clustering algorithm. To improve Graph Neural Network's performance, we propose a new layer type (EmulsionConv) that takes into account geometrical properties of shower development in ECC brick. For the clustering of overlapping showers, we use a modified hierarchical density-based clustering algorithm. Our method does not use any prior information about the incoming particles and identifies up to 82% of electromagnetic showers in emulsion detectors. The mean energy resolution over $17,715$ showers is 27%. The main test bench for the algorithm for reconstructing electromagnetic showers is going to be SND@LHC.
