1. Introduction to Social Media Algorithms

Social media algorithms are complex sets of rules and machine learning models that determine:

• What content appears in your feed
• The order in which posts are shown
• Which recommendations you receive

These systems analyze thousands of data points to maximize platform engagement while balancing business objectives.

2. Core Components of Social Media Algorithms

2.1 Input Signals (What Algorithms Consider)

• User Engagement: Likes, comments, shares, saves, watch time
• Content Characteristics: Post type (image/video/text), captions, hashtags
• User History: Past interactions, time spent on similar content
• Relationship Data: How closely connected you are to the poster
• Timeliness: How recent the post is
• Device/Usage Patterns: Session length, time of day

2.2 Ranking Factors by Platform

3. Algorithm Types Across Platforms

3.1 The Facebook/Instagram Algorithm

• Uses multi-stage ranking:
  1. Inventory selection (thousands of possible posts)
  2. Signal scoring (predicts engagement probability)
  3. Final ranking (personalized order)
• Prioritizes “meaningful interactions” (comments > likes)

3.2 TikTok’s Recommendation Engine

• Content-based filtering:
  • Analyzes visual/audio elements
  • Tracks micro-interactions (rewatches, partial views)
• Collaborative filtering:
  • “Users who watched this also watched…”
• Extremely sensitive to early engagement signals

3.3 Twitter/X’s Timeline Algorithm

• Two feed options:
  • Chronological (For You tab)
  • Algorithmic (Following tab)
• Weights:
  • Recency (50%)
  • Personal relevance (30%)
  • Engagement (20%)

4. How Algorithms Learn From You

4.1 Implicit Feedback Collection

• Dwell time: How long you view a post
• Scroll velocity: How quickly you scroll past content
• Haptic feedback: Whether you “long-press” to save

4.2 Explicit Feedback Mechanisms

• “Show me less like this” options
• Interest preference selectors
• Surveys about recommended content

5. Business Considerations in Algorithm Design

5.1 Platform Objectives

• Maximize Time-on-App (TikTok, Instagram)
• Encourage Connections (Facebook, LinkedIn)
• Boost Ad Revenue (All platforms)

5.2 Ethical Challenges

• Filter bubbles: Limited exposure to diverse views
• Addictive design: Infinite scroll, variable rewards
• Misinformation spread: Controversial content often gets prioritized

6. How Users Can “Game” the Algorithm

6.1 Content Strategies That Work

• Instagram: Carousels get 3x more engagement
• TikTok: First 3 seconds are critical for retention
• Twitter: Threads with 3-5 tweets perform best
• LinkedIn: Posts between 1,900-2,000 characters get most shares

6.2 Posting Best Practices

• Optimal Times:
  • Instagram: Weekdays 11am-2pm
  • LinkedIn: Tuesday-Thursday 8-10am
  • TikTok: Evenings 7-11pm
• Engagement Tactics:
  • Ask questions in captions
  • Use trending audio (for video)
  • Respond to comments quickly

7. Recent Algorithm Updates (2023-2024)

• Instagram prioritizing original content over reposts
• TikTok testing “dislike” button for refinement
• LinkedIn downgrading hashtag-only posts
• Twitter/X boosting paid verified accounts

8. The Future of Social Algorithms

• Increased personalization using generative AI
• More user control over feed preferences
• Decentralized alternatives (Mastodon, Bluesky)
• Regulatory changes (EU’s Digital Services Act)

9. Key Takeaways

1. Social algorithms prioritize engagement over chronology
2. Each platform has unique ranking factors
3. Early engagement dramatically affects reach
4. Users can strategically adapt to algorithmic preferences
5. Platforms constantly tweak their algorithms (average 2-3 major updates per year)

Understanding these systems helps users and creators navigate social media more effectively while being aware of their psychological impacts and commercial motivations.

1. Introduction to the FFT

The Fast Fourier Transform is one of the most important algorithms of the 20th century, revolutionizing digital signal processing and numerical computation. First popularized by Cooley and Tukey in 1965 (though known to Gauss as early as 1805), the FFT computes the Discrete Fourier Transform (DFT) in O(n log n) time instead of the naive O(n²) approach.

2. Mathematical Foundations

2.1 The Discrete Fourier Transform

For a sequence x₀, x₁, …, xₙ₋₁, the DFT is defined as:

Xₖ = Σ_{j=0}^{n-1} x_j e^{-2πijk/n} for k = 0,…,n-1

Where:

• n is the number of samples
• Xₖ are the frequency domain components
• e^{-2πijk/n} are the roots of unity

2.2 The FFT Insight

The key observation is that a DFT of size n can be decomposed into:

• Two DFTs of size n/2 (even and odd indices)
• Combined via “twiddle factors” (roots of unity)

This divide-and-conquer approach reduces the complexity from O(n²) to O(n log n).

3. Algorithm Implementation

3.1 Radix-2 Cooley-Tukey Algorithm

The most common implementation requires n to be a power of 2:

Copy

function FFT(x):
    n = length(x)
    if n == 1:
        return x
    even = FFT(x[0::2])  # Even indices
    odd = FFT(x[1::2])   # Odd indices
    T = [exp(-2πi k/n) * odd[k] for k in 0:n/2-1]
    return [even[k] + T[k] for k in 0:n/2-1] + 
           [even[k] - T[k] for k in 0:n/2-1]

3.2 Key Optimizations

• Bit-reversal permutation: Reorders input for in-place computation
• Twiddle factor caching: Precomputes roots of unity
• SIMD vectorization: Exploits modern CPU instructions

4. Computational Complexity

For n=4096, this means:

• 16.7M operations → 49k operations (340× speedup)

5. Practical Applications

• Molecular dynamics simulations
• Weather prediction models

5.3 Cryptography

• Polynomial multiplication (NTRU, lattice-based crypto)
• Integer multiplication (Schönhage–Strassen algorithm)

6. Modern Variations

6.1 Non-Power-of-Two FFTs

• Bluestein’s algorithm (arbitrary n)
• Prime-factor algorithm (n = n₁n₂ with coprime factors)

6.2 Parallel FFT

• Distributed memory versions (MPI)
• GPU-accelerated implementations (CUDA, OpenCL)

6.3 Sparse FFT

• O(k log n) for signals with k significant frequencies
• Used in compressed sensing applications

7. Hardware Considerations

7.1 Numerical Stability

• Careful twiddle factor calculation needed
• Fixed-point vs floating-point implementations

7.2 Cache Optimization

• Blocking strategies for large transforms
• Memory access pattern considerations

8. Historical Impact

The FFT’s development:

• Enabled real-time digital signal processing
• Reduced computation times from hours to seconds
• Won the 1994 IEEE Milestone Award
• Was called “the most important numerical algorithm of our lifetime” by Gilbert Strang

9. Current Research Frontiers

Introduction to E-Paper Technology

Electronic ink (E-Ink) displays, also known as electrophoretic displays (EPD), represent a unique class of low-power, reflective display technology. First commercialized in the late 1990s, E-Ink has become synonymous with e-readers but has since expanded into diverse applications due to its distinctive properties.

E-Ink displays utilize microcapsules or microcups containing charged pigment particles suspended in a clear fluid. The core electrophoretic mechanism involves:

1. Bichromal Particle System:
   • Positively charged white particles (typically titanium dioxide)
   • Negatively charged black particles (carbon-based)
2. Electrode-Driven Manipulation:
   • Application of an electric field moves particles to the surface
   • No power is required to maintain a static image (bistable nature)
3. Reflective Operation:
   • Relies on ambient light (no backlight)
   • Mimics the appearance of printed paper

This architecture enables:

• Exceptionally low power consumption (μW/cm² range)
• Wide viewing angles (~180°)
• Sunlight readability
