I have experience in python, numpy, scipy, pandas, matplotlib... But I am especially finding logical thinking and statistics challenging. I can study in either Vietnamese or English. Mentoring hours would be as follows: 1 weekend Saturday or Sunday, each lesson for 2 hours (We can talk about this) Total 2 hours per week ------------------------------------------------------------------------------------------------------...

...escalate. The core must combine traditional threat-intel techniques with machine-learning pipelines so the system continuously adapts as new data arrives. Here’s what success looks like to me: • A modular data-collection layer that can stream pcap, NetFlow, or similar log formats into a preprocessing engine. • Feature-engineering and model-training code written in Python (feel free to leverage Pandas, scikit-learn, TensorFlow, PyTorch—whatever best suits the task). • A detection component that scores incoming traffic and raises alerts via a simple REST API or CLI output. • Clear documentation covering setup, retraining, and how new data sources—such as endpoint events or social-media threat chatter—could be plugged in later. ...

...ready for downstream analytics. You will receive the source file in CSV (UTF-8) plus a short style guide that shows the exact output I need. Please return the cleaned file and a short change log summarizing the transformations you applied. Accuracy and respect for the original content are crucial; no new data should be introduced or removed. Tools like Excel, Google Sheets, OpenRefine, or Python (pandas) are all fine—use whatever helps you turn this around quickly and reliably....

The app should read, clean, and merge these feeds on the fly, then offer clear visual insights through line charts, area charts, and any other plots that make trends, seasonality, and anomalies obvious. Under the hood I expect well-structured, reusable Python code that leans on pandas for manipulation, SQLAlchemy (or similar) for database access, and a lightweight requests layer for the APIs. Caching, session-state handling, and responsive layout controls are important so the interface feels fast even as data volumes grow. Deliverables • Streamlit app folder with modular, commented Python scripts • A config file (YAML or .env) that...

I’m looking for a data scientist based anywhere in Latin America to help me create reliable predictive models for a finance-focused project. You’ll start with large historical datasets stored in SQL and deliver models that accurately forecast key financial indicators. I work mainly with Python, so you’ll find Pandas, NumPy, Scikit-learn and, when deep learning is justified, TensorFlow already in place. If you prefer R for certain tasks, that’s perfectly fine as long as the final workflow remains reproducible. The end-user needs to consume insights through Power BI, so once the model is validated I’ll ask you to craft intuitive dashboards that highlight drivers, confidence ranges and any red-flag anomalies the model detects. Solid statistical grounding ...

The core task is straightforward: ingest the raw text files I provide, clean and structure them appropriately, then run exploratory and statistical analyses that reveal key themes, sentiment trends, and any significant correlations you uncover. Feel free to use Python with pandas, NumPy, NLTK, spaCy, or other standard NLP and data-analysis libraries—whatever you are most comfortable with as long as the workflow is reproducible. Because I don’t have a hard deadline, quality and clarity matter more than speed. You will deliver: • Well-commented notebooks or scripts that walk through each analysis step • A concise report (PDF...

You’ll log into shared Google Sheets, pull information from public sources or APIs, verify accuracy, and present concise insights that let me make quick decisions. Experience with Excel or Sheets functions (LOOKUPs, pivot tables, basic charts) and any lightweight statistical tool such as Python/pandas or R is a plus, but solid attention to detail matters most. I’ll set clear weekly objectives up front. Typical deliverables include: • A cleaned spreadsheet ready for analysis • A brief written summary (no more than one page) highlighting key findings and anomalies Before we start, send a short note telling me your favourite dataset you’ve worked on...

I need to turn a tangle of monthly transaction files into one clean, consistent source of truth. The job touches three tools: • Python – Write well-structured scripts (pandas, openpyxl, maybe pyodbc) that handle data cleaning, exploratory analysis, and the recurring automation needed to pull from / push to my databases and workbooks. • MS Access – Build and fine-tune queries, keep the tables organised, and set up ready-to-run reports that mirror the logic in the Python workflow. • MS Excel – Craft the right formulas, dynamic pivot tables, and clear visualisations so stakeholders can slice the data without touching code. The core flow should be: ingest raw Excel dumps, clean and reconcile them in Python, store the harmonised tables in Access, th...

...and connects to my broker’s API out of the box. • Parameter file or dashboard so I can tweak risk limits, symbols, and indicator thresholds. • Back-test results on one year of one-minute data plus a walk-forward test on the last 90 trading days, both clearly outperforming buy-and-hold under equal risk. • Quick-start guide and a brief screen-share hand-off. Tech stack is open—Python with pandas and TA-Lib is fine, but if you prefer something lower-latency like C++ or a paired Python/C++ engine, I’m game as long as installation is straightforward on a standard U.S. VPS. I’m ready to begin as soon as I find the right coder-trader hybrid. Send a short note describing your live trading experience and one or two algos you’ve built th...

...straight into my existing systems. My current bottleneck is doing this by hand, so the solution must run unattended once configured. Although my immediate goal is straightforward data processing, I’m open to seeing how you’d weave in text extraction, transformation, or even lightweight analysis if that simplifies the pipeline or adds value. I work comfortably with Python, so a solution built with pandas, spaCy, or similar libraries would fit right in, but I’m not married to any single toolset as long as the final deliverable is easy for me to maintain. Deliverables • Source code and any dependency list • A short README explaining setup, configuration variables, and how to run the job • One worked example showing the raw input and the process...

I expect well-structured, runnable code—Python with pandas/NumPy/SciPy is typical, though another language is fine if it delivers the same reproducible results—along with a concise README that shows how to install dependencies, feed sample logs, and interpret the output. Success is measured by: • Clean execution on my sample dataset (≈1 GB of mixed user activity). • Alerts that capture ...

...are straightforward TXT—no embedded markup or JSON structures—so the solution can focus entirely on pattern analysis rather than parsing exotic formats. Because the anomalies are behavioural rather than simply extreme numeric values, the detection logic must look for irregular sequences, unexpected combinations of fields, or sudden structural deviations. I’m happy with a Python‐based approach (pandas, scikit-learn, PyOD, or similar libraries come to mind), but I’m open to another language if it keeps the setup lightweight and easily deployable on a Linux server. Speed matters: each hourly log is time-stamped and should be processed within the hour so downstream analytics always work with clean data. Your script or small tool should run from the command...

...is to move everything into the standardized Excel import template required by our new SAP environment without typing line-by-line. I would like an automated solution—preferably a lightweight AI-assisted script or model—that can: 1. read the existing Excel files, 2. map each column to the exact fields SAP expects, and 3. export a clean, ready-to-upload template with zero data loss. Python (pandas / openpyxl), VBA, or a low-code Power Query setup are all acceptable as long as the end result is fast and repeatable for future batches. Built-in data checks for duplicates, negative balances, or mismatched contract IDs will be essential so we catch issues before the SAP import stage.
