Before	After

🧹 Dirty Data

Load without worry

Easily load and align mismatched CSV files-hello IoT. This utility intelligently collects, normalizes, and organizes messy datasets — so you can focus on the analysis, not the cleanup. 🚀

Vector.load_folder(path) loads a folder of CSV files with potentially mismatched or missing columns,
aligns all columns based on their headers, and combines them into a single clean DataFrame.
Missing columns in any file are automatically filled with NaN values to maintain consistency.

Perfect for messy datasets where CSVs don't share the exact same structure!

Cleaning is done one layer up with sp00kyDF.get_clean_df() ✨🧹

This method returns a cleaned version of the DataFrame by performing the following steps:

1. 🧩 Removes duplicate rows (performed twice to ensure thorough cleaning)
2. 🚫📊 Clips outlier values based on the Z-score method (an Interquartile Range (IQR) method is also available)
3. 🏷️ Standardizes column names for consistency
4. ❌🕳️ (Optionally drops null values — currently commented out)

Finally, it returns the cleaned DataFrame ready for analysis. 🎯

📚 Documentation

🌙 Pipeline 🔮

This guide shows how to take messy tabular data, purify it with sp.DF, explore it with sp.vector , and train a custom neural network — using the sp.nn. This package is a wrapper for scientific modules and open-source education project!

Abstraction

sp.DF sits ontop of pandas, numpy, and matplotlib sp.NN sit ontop of sp.DF and py.torch

---

**1. Imports and Cleaning

import sp00kyvectors as sp  # ✨ The full spooky toolbox
# Your standard np, pd, and plt cmds work as this wrapper sits on top of them all 

df = sp.df(path_to_messy_csv_folder)
df.drop_nulls(threshold=0.4)       # Drop columns with >40% nulls
df.fill_nulls(strategy='median')   # Fill remaining nulls with median
df.standardize_column_names()      # Lowercase + underscores
df.clip_outliers(z_thresh=3)       # Remove extreme outliers
df_clean = sp.get_clean_df()       # Fully cleaned DataFrame

---

3. Vectorize Columns

Each numeric column becomes a Vector for statistical exploration & visualization. A vector is a numpy array within a pandas dataframe to represent dimensions. Pretty cool.

Now each column can be plotted, scaled, combined, or compared using Vector operations which means fast.

🔮 Phase 2: Custom Neural Network (NN) in sp00kyvectors 🌙

The sp.NN module provides a simple, customizable feed‑forward network with random activation layers. It's a py-torch model, with a few peer-reviewed optimization tricks, and easier layer control. Use it to turn your cleaned & vectorized features into predictions.

---

init Arguments

• input_size (int): Number of input features (dimensionality of your X).
• hidden_sizes (List[int]): Amount and Sizes of each hidden layer, e.g. [...,64, 32, ...].
• output_size (int): Number of outputs (e.g. 1 for a single regression target).

---

✨ Description

• Stacks Linear → RandomActivation pairs for each hidden layer.
• Final Linear projects to your desired output size.
• Random activations chosen per layer from [ReLU, Tanh, Sigmoid, ELU].

---

1. Build & Train the Neural Network 🌙

model = sp.NN(input_size=X.shape[1], hidden_sizes=[64, 32], output_size=1)
model.train_model(train_loader, epochs=20, lr=0.001)

---

2. Evaluate the Model

test_loss = model.test_model(train_loader)
print(f"Test Loss: {test_loss:.4f}")

**3. Predict

model.forward(input)

---

📈 Plotting

Every col in sp.DF is a numpy vector. Represented with v below.

.histogram(log=False)

Plots a histogram of the vector values. Set log=True for logarithmic scale.

v.histogram()
v.histogram(log=True)

---

.plot_vectors(mode="line", entropy=False)

Plots 2D vectors.

• mode: "line", "arrow", or "trail"
• entropy: if True, colorizes vectors by entropy

v2d.plot_vectors(mode="arrow", entropy=True)

---

🔮 Utilities

.gaussian_smooth(sigma=1.0)

Applies Gaussian smoothing to the vector.

v_smooth = v.gaussian_smooth(sigma=2.0)

---

💀 Dunder Methods

__repr__()

Pretty string representation.

print(v)  # Vector(mean=3.0, std=1.58, ...)

---

🛠 Developer Notes

• Internal data is stored as numpy.ndarray
• Methods use scipy.stats, numpy, and matplotlib
• Entropy assumes aligned distributions (normalized first)
