I have three full years of trend data sitting in a single Excel workbook. Each row records a two-digit value, and I now need a machine-learning model that can reliably forecast both the “inside” and “outside” four-digit combinations drawn from the digits 0-9. Historical trends are the only signal I want the model to learn from; please do not add external data or random sampling. Target performance is 90 % prediction accuracy, measured on a hold-out set we will agree on before training begins. I will share the Excel file once we start; you deliver: • Clean, well-commented code (Python preferred) that loads the spreadsheet, prepares the data, trains the model, and outputs predictions. • A brief write-up of feature engineering, model choice, and validatio...

I am looking for an experienced developer, biomedical engineer, or development team capable of building an advanced medical diagnostic system. The concept is to create a portable handheld device that can analyze a small blood sample from a patient. The blood would be inserted into the machine through a cartridge or slot system, similar to how a phone charger plugs into a phone. Once the blood sample is inserted, the device should process the sample and send the results to a mobile or web application, where the user or doctor can view the analysis results and health indicators. The goal is to develop a system that can help identify diseases or health conditions based on blood analysis with very high accuracy and reliability. This project will start with a prototype, and if the developer...

I have several years of historical sales records spread across CSV files, Excel workbooks, and a database. I want you to turn that mixed-source information into a clean, consistent dataset, explore it for trends and seasonality, and then build a machine-learning model that can reliably project future sales. Data preparation must cover every stage—handling missing values, normalising numeric fields, and performing any transformations needed to feed the algorithms. Once the data is tidy, run an exploratory analysis so I can clearly see the patterns that drive revenue, especially how previous sales, marketing spend, and seasonal shifts interact. For modelling, I am open to linear regression, Random Forest, ARIMA, or another regression-based technique you can justify in the report. The...
