    I have a folder of 12 short-duration sound samples and I need two metrics extracted from every file: the three tristimulus values and the spectral centroid. All data must be processed in Python, ideally with Librosa at the core; you are free to lean on NumPy, SciPy or Pandas for supporting math and I/O. Please send back: • A clean, well-commented .py script (or a Jupyter notebook) that loads an arbitrary batch of WAV/AIFF files and outputs a table containing filename, tristimulus 1-2-3, and centroid. • A CSV (or similar) generated by running that script on my dataset. • A short README describing assumptions (e.g., window size, hop length, any pre-emphasis) so I can reproduce results or tweak parameters. I will share the audio samples as soon as we start; the to...

    ...version, my research notes, and the raw data set. The text follows Chicago style, so every edit—from footnotes to bibliography—has to respect that convention. Here is what I need from you: • Edit and streamline the entire manuscript for clarity, logical flow, and persuasive argumentation while eliminating grammatical or stylistic errors. • Run or verify my data analysis in SPSS or Python (pandas, SciPy, or a comparable library), then weave the statistical interpretation seamlessly into the discussion section. • Ensure every citation, table, and figure aligns with Chicago guidelines and that all references are cross-checked for accuracy. Acceptance criteria • Clean, publication-ready manuscript (tracked-changes + final version) in .docx for...

    ...clean the dataset, handle missing or noisy readings, and then produce descriptive statistics (mean, median, variance, standard deviation, covariance), visualisations that highlight key insights (time-series plots, histograms, perhaps a correlation heat map), and a concise written interpretation of what the numbers show. I’m comfortable with Python, so a Jupyter Notebook built with pandas, NumPy, SciPy and Matplotlib or Seaborn is ideal. If you prefer R or MATLAB, that’s fine too—just keep the code readable and reproducible. Deliverables • Cleaned data file in the same structure as the original • Well-commented analysis notebook or script • Exported graphs (PNG or PDF) • Short report (1-2 pages) summarising findings and highlighting ...

    ...analysis, time-frequency techniques—whatever best extracts degradation features), train a predictive model, then expose Remaining Useful Life or probability-of-failure metrics in an intuitive web dashboard. Vibration data will be the only input in the first release, so your signal-processing and machine-learning choices must squeeze maximum insight from that single source. I’m open to Python (NumPy, SciPy, scikit-learn, TensorFlow) or MATLAB toolchains as long as the final product is easy for me to retrain with new runs. Deliverables • Source code with clear comments and a short setup guide • A lightweight dashboard (Streamlit, Dash, or similar) showing live health indicators, trend plots and a simple traffic-light status • A sample dataset and ...

    ...advanced Python users who now want to master Data Science and Machine Learning. They already write clean, object-oriented code, but need structured help turning that skill into solid analytical practice. Your role is to meet them online, break down real-world datasets, and walk them through both the theory and hands-on implementation of: • Statistical analysis & data visualisation: pandas, NumPy, SciPy, Matplotlib, Seaborn, Plotly, plus the “why” behind each chart or test. • Core machine-learning algorithms: from linear and logistic regression through tree-based models, clustering, model evaluation and cross-validation using scikit-learn. Weekly rhythm I have in mind is one live workshop (60–90 min) and one code-review/drop-in clinic. I&rs...

    ...questions I want the model to answer. What I’m missing is an experienced collaborator who can stress-test the assumptions, confirm the equations make sense biologically, and help shape the discussion so it stands up to peer review. Familiarity with population genetics, evolutionary game theory, or comparative methods will be especially helpful, and the ability to use tools like R, Python (NumPy/SciPy), or Mathematica for quick simulations will make the process smoother. Ultimately, I’d like to finish with: – a polished set of equations or simulation code, – clearly interpreted results tied back to the current literature, and – concise text ready to be slotted into my manuscript draft. If you enjoy dissecting evolutionary theory and have a kna...

My focus is preskriptif analysis, so I’m not just after insights—I need an optimizer that suggests exactly how to rebalance a multi-asset portfolio for better risk-adjusted returns. The raw figures are already collected; what’s missing is the model that converts them into concrete decisions. You’re free to choose the most suitable stack—Python (Pandas, NumPy, SciPy, PyPortfolioOpt), R, or another reliable tool—as long as the results are reproducible and the code is well commented.
