🧠 AI3 Tensor Operations

Supported Operations

The ESP32 can perform various AI computations optimized for its hardware:

Matrix Operations

// 4x4 matrix multiplication (optimized for ESP32)
let matrix_a = [[1.0, 2.0, 3.0, 4.0],
                [5.0, 6.0, 7.0, 8.0],
                [9.0, 10.0, 11.0, 12.0],
                [13.0, 14.0, 15.0, 16.0]];

let matrix_b = [[0.1, 0.2, 0.3, 0.4],
                [0.5, 0.6, 0.7, 0.8],
                [0.9, 1.0, 1.1, 1.2],
                [1.3, 1.4, 1.5, 1.6]];

// Result computed on ESP32
let result = esp32_matrix_multiply(matrix_a, matrix_b);

Convolution Operations

// 1D convolution with smoothing kernel
let signal = [1.0, 2.0, 3.0, 4.0, 5.0, 4.0, 3.0, 2.0, 1.0];
let kernel = [0.25, 0.5, 0.25]; // Smoothing kernel

let convolved = esp32_convolution_1d(signal, kernel);

Neural Network Forward Pass

// Simple neural network inference
let input = [0.5, 0.3, 0.8, 0.2];
let weights = [0.1, 0.2], [0.3, 0.4], [0.5, 0.6], [0.7, 0.8](/odelyzid/.AI3/wiki/0.1,-0.2],-[0.3,-0.4],-[0.5,-0.6],-[0.7,-0.8);
let bias = [0.1, 0.2];

let output = esp32_neural_forward(input, weights, bias);

💡 Power Optimization

Power Management Strategies

// Dynamic power scaling based on temperature
if temperature > 70.0 {
    mining_intensity = 0.5; // Reduce to 50%
} else if temperature > 60.0 {
    mining_intensity = 0.75; // Reduce to 75%
} else {
    mining_intensity = 1.0; // Full power
}

Energy Efficiency Tips

Use External Antenna: Improves WiFi signal, reduces power consumption
Stable Power Supply: Prevents voltage drops and instability
Heat Management: Add heat sinks to maintain optimal temperature
WiFi Optimization: Place near router for strong signal
Task Scheduling: Mine during off-peak hours for better rewards
