Machine Learning from Scratch by Danny Friedman

This book is for readers looking to learn new machine learning algorithms or understand algorithms at a deeper level. Specifically, it is intended for readers interested in seeing machine learning algorithms derived from start to finish. Seeing these derivations might help a reader previously unfamiliar with common algorithms understand how they work intuitively. Or, seeing these derivations might help a reader experienced in modeling understand how different algorithms create the models they do and the advantages and disadvantages of each one.

This book will be most helpful for those with practice in basic modeling. It does not review best practicesβ€”such as feature engineering or balancing response variablesβ€”or discuss in depth when certain models are more appropriate than others. Instead, it focuses on the elements of those models.

πŸ”₯ Huge cheat sheet for plotting in Matplotlib with code examples

πŸ“Š Matplotlib is a powerful plotting library in Python used for creating static, animated, and interactive visualizations.

Main features of Matplotlib:
πŸ’¬ Versatility: can generate a wide range of plots including line plots, scatter plots, bar charts, histograms, and pie charts.

πŸ’¬ Customization: offers extensive options to control every aspect of the plot such as line styles, colors, markers, labels, and annotations.

πŸ’¬ Integration with NumPy: easily integrates with NumPy, simplifying plotting of data arrays directly.

πŸ’¬ Publication quality: creates high-quality plots suitable for publication, with precise control over aesthetics.

πŸ’¬ Extensibility: easily extended with a large ecosystem of additional toolkits and extensions, such as Seaborn and Pandas plotting functions.

πŸ’¬ Cross-platform: platform-independent and can run on various operating systems including Windows, macOS, and Linux.

πŸ’¬ Interactive plots: supports interactive plotting with widgets and event handling, allowing users to dynamically explore data.

β€’ Apply a simple blur filter.
from PIL import ImageFilter
blurred_img = img.filter(ImageFilter.BLUR)

β€’ Apply a box blur with a given radius.
box_blur = img.filter(ImageFilter.BoxBlur(5))

β€’ Apply a Gaussian blur.
gaussian_blur = img.filter(ImageFilter.GaussianBlur(radius=2))

β€’ Sharpen the image.
sharpened = img.filter(ImageFilter.SHARPEN)

β€’ Find edges.
edges = img.filter(ImageFilter.FIND_EDGES)

β€’ Enhance edges.
edge_enhanced = img.filter(ImageFilter.EDGE_ENHANCE)

β€’ Emboss the image.
embossed = img.filter(ImageFilter.EMBOSS)

β€’ Find contours.
contours = img.filter(ImageFilter.CONTOUR)


VII. Image Enhancement (ImageEnhance)

β€’ Adjust color saturation.
from PIL import ImageEnhance
enhancer = ImageEnhance.Color(img)
vibrant_img = enhancer.enhance(2.0)

β€’ Adjust brightness.
enhancer = ImageEnhance.Brightness(img)
bright_img = enhancer.enhance(1.5)

β€’ Adjust contrast.
enhancer = ImageEnhance.Contrast(img)
contrast_img = enhancer.enhance(1.5)

β€’ Adjust sharpness.
enhancer = ImageEnhance.Sharpness(img)
sharp_img = enhancer.enhance(2.0)


VIII. Drawing (ImageDraw & ImageFont)

β€’ Draw text on an image.
from PIL import ImageDraw, ImageFont
draw = ImageDraw.Draw(img)
font = ImageFont.truetype("arial.ttf", 36)
draw.text((10, 10), "Hello", font=font, fill="red")

β€’ Draw a line.
draw.line((0, 0, 100, 200), fill="blue", width=3)

β€’ Draw a rectangle (outline).
draw.rectangle([10, 10, 90, 60], outline="green", width=2)

β€’ Draw a filled ellipse.
draw.ellipse([100, 100, 180, 150], fill="yellow")
