One of the pressing challenges in the domain of customer churn prediction (CCP) is the accurate classification of imbalanced datasets. In this study, we conduct a comprehensive investigation into CCP within the banking sector, utilizing an extensive range of datasets. We integrate robust models capable of capturing complex non-linear relationships to develop hybrid segmented models for CCP. Additionally, we introduce a novel, model-agnostic technique that extends SHAP (SHapley Additive exPlanations) to ensure the interpretability of these segmented hybrid models. The approach rigorously evaluates the performance of various predictive models across 14 customer turnover datasets. The interpretability of the new model-agnostic method is showcased through a detailed case study, providing clear insights into model decision-making processes. The staged comparison trials reveal that the Voting Classifier, XGBoost, CatBoost, and LGBoost achieve accuracies of 0.81, 0.84, 0.82, and 0.83, respectively. Among these, XGBoost demonstrates the highest prediction performance, emerging as the recommended algorithm. This study not only advances the accuracy of CCP models in the banking sector but also enhances their interpretability, facilitating more informed decision-making.</p></div>","PeriodicalId":717,"journal":{"name":"National Academy Science Letters","volume":"48 4","pages":"459 - 463"},"PeriodicalIF":1.3,"publicationDate":"2024-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145163244","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To optimally utilize land resources and improve profitability, experiment on arecanut based cropping system with culantro was initiated. Culantro is a popular aromatic herb used for imparting green coriander like aroma to the cuisines. Intercropping resulted in an additional yield of culantro (2.21 t/ha), increasing net returns to ₹ 13,03,065/- compared to ₹ 9,59,600/- from the sole arecanut crop.

The identification and mass culturing are pivotal for field applications of these beneficial nematodes. The EPNs population can serve as a limiting factor in the biopesticides formulation and field spray application. This study was formulated to curb out the limitation of low population of entomopathogenic nematodes in the soil using the in vivo and in vitro mass production techniques. An indigenous strain of genus <i>Heterorhabditis</i> was isolated from Solan district of Himachal Pradesh and then mass cultured in the laboratory. In in vivo technique, larvae of <i>Galleria mellonella</i> Linnaeus (greater wax moth) and <i>Corcyra cephalonica</i> Stainton (rice moth) were used as bait insects in modified method of white trap and as a result, a greater number of infective juvenile (IJs) were recovered of IJs were 3 days in modified WM (1–2 million population ranges) and the maximum progeny production within the range of 2–3 million was observed on DBM with emergence time of 7 days. The present investigation suggests that the utilization of different mass production techniques can curb the constraint of low population of EPNs from, <i>Galleria mellonella</i> (23100 IJs) as compared to <i>Corcyra cephalonica</i> (12840 IJs). The culture media, including modified dog biscuit medium (DBM), modified kabuli gram medium (KGM), black gram medium (BGM) and modified wout medium (WM) were used for the in vitro mass production of isolated nematodes. The minimum time taken for emergence of IJs were 3 days in modified WM (1–2 million population ranges) and the maximum progeny production within the range of 2–3 million was observed on DBM with emergence time of 7 days. The use of in vivo culturing was found to be best for initial isolation and small-scale mass production and greater wax moth is better bait insect in comparison to rice moth. The use of in vitro technique was helpful in mass multiplication in large number of the isolate, therefore making it convenient for field application.
