💡 Pro tip: This is one of those techniques that will make you look like a data science wizard! Understanding Basic Gradient Descent - Made Simple!

Gradient descent forms the foundation of optimization in neural networks. It iteratively adjusts parameters by computing gradients of the loss function with respect to model parameters, moving in the direction that reduces the loss most rapidly.

Let me walk you through this step by step! Here’s how we can tackle this:

import numpy as np

class GradientDescent:
    def __init__(self, learning_rate=0.01):
        self.learning_rate = learning_rate
        
    def update(self, params, grads):
        # Simple update rule: params = params - learning_rate * gradients
        return params - self.learning_rate * grads

# Example usage
params = np.array([1.0, 2.0])
grads = np.array([0.1, 0.2])
optimizer = GradientDescent(learning_rate=0.1)
new_params = optimizer.update(params, grads)
print(f"Original params: {params}")
print(f"Updated params: {new_params}")

🎉 You’re doing great! This concept might seem tricky at first, but you’ve got this! Implementing Stochastic Gradient Descent - Made Simple!

Stochastic Gradient Descent (SGD) processes one sample at a time, making it more memory-efficient and often faster than batch gradient descent. It introduces randomness that can help escape local minima.

Don’t worry, this is easier than it looks! Here’s how we can tackle this:

class SGD:
    def __init__(self, learning_rate=0.01):
        self.learning_rate = learning_rate
        
    def compute_gradients(self, X, y, w, b):
        m = X.shape[0]
        y_pred = X.dot(w) + b
        dw = (1/m) * X.T.dot(y_pred - y)
        db = (1/m) * np.sum(y_pred - y)
        return dw, db
    
    def step(self, w, b, dw, db):
        w -= self.learning_rate * dw
        b -= self.learning_rate * db
        return w, b

# Example usage
X = np.random.randn(100, 2)
y = np.random.randn(100)
w = np.zeros(2)
b = 0
sgd = SGD(learning_rate=0.01)
dw, db = sgd.compute_gradients(X, y, w, b)
w_new, b_new = sgd.step(w, b, dw, db)

✨ Cool fact: Many professional data scientists use this exact approach in their daily work! Momentum Optimizer Implementation - Made Simple!

The momentum optimizer addresses oscillation issues in standard gradient descent by accumulating a velocity vector in directions of persistent reduction in the objective, enabling faster convergence and better handling of noisy gradients.

Let’s make this super clear! Here’s how we can tackle this:

class MomentumOptimizer:
    def __init__(self, learning_rate=0.01, momentum=0.9):
        self.learning_rate = learning_rate
        self.momentum = momentum
        self.velocity = None
        
    def update(self, params, grads):
        if self.velocity is None:
            self.velocity = np.zeros_like(params)
            
        self.velocity = self.momentum * self.velocity - self.learning_rate * grads
        return params + self.velocity

# Example usage
optimizer = MomentumOptimizer()
params = np.array([1.0, -1.0])

🔥 Level up: Once you master this, you’ll be solving problems like a pro! Adaptive Gradient (AdaGrad) Implementation - Made Simple!

AdaGrad adapts learning rates to parameters, performing smaller updates for frequently updated parameters and larger updates for infrequent ones. This makes it particularly effective for sparse data and different scales of features.

Don’t worry, this is easier than it looks! Here’s how we can tackle this:

class AdaGrad:
    def __init__(self, learning_rate=0.01, epsilon=1e-8):

    def update(self, params, grads):
        if self.accumulated_grads is None:
            self.accumulated_grads = np.zeros_like(params)
            
        self.accumulated_grads += np.square(grads)
        adjusted_grads = grads / (np.sqrt(self.accumulated_grads) + self.epsilon)
        return params - self.learning_rate * adjusted_grads

# Example usage
optimizer = AdaGrad()
params = np.array([1.0, 2.0])

        self.cache = self.decay_rate * self.cache + (1 - self.decay_rate) * np.square(grads)
        adjusted_grads = grads / (np.sqrt(self.cache) + self.epsilon)
        return params - self.learning_rate * adjusted_grads

# Example usage

for _ in range(3):
    params = optimizer.update(params, grads)
    print(f"Updated parameters: {params}")

            self.v = np.zeros_like(params)
            
        self.t += 1
        
        # Update biased first moment estimate
        self.m = self.beta1 * self.m + (1 - self.beta1) * grads
        # Update biased second raw moment estimate
        self.v = self.beta2 * self.v + (1 - self.beta2) * np.square(grads)
        
        # Compute bias-corrected first moment estimate
        m_hat = self.m / (1 - self.beta1**self.t)

🚀 cool Learning Rate Scheduling with Warmup - Made Simple!

Implementation of cool learning rate scheduling techniques including linear warmup and cosine decay with restarts, which have shown improved performance in training deep neural networks.

Let’s break this down together! Here’s how we can tackle this:

class AdvancedLRScheduler:
    def __init__(self, initial_lr=0.001, min_lr=1e-6):
        self.initial_lr = initial_lr
        self.min_lr = min_lr
        
    def linear_warmup(self, current_step, warmup_steps):
        """Linear warmup followed by constant learning rate"""
        if current_step < warmup_steps:
            return self.initial_lr * (current_step / warmup_steps)
        return self.initial_lr
    
    def cosine_decay_restart(self, current_step, first_decay_steps, 
                            t_mul=2.0, m_mul=0.5):
        """Cosine decay with warm restarts"""
        first_decay_steps = max(1, first_decay_steps)
        alpha = self.min_lr / self.initial_lr
        
        completed_fraction = current_step / first_decay_steps
        
        # Calculate restart cycle
        cycle = np.floor(np.log2(completed_fraction * (t_mul - 1.0) + 1.0))
        current_period = first_decay_steps * t_mul ** (cycle - 1)
        current_step_in_period = current_step - (
            first_decay_steps * (t_mul ** cycle - 1.0) / (t_mul - 1.0)
        )
        
        fraction_in_period = current_step_in_period / current_period
        cosine_decay = 0.5 * (1.0 + np.cos(np.pi * fraction_in_period))
        decayed = (1 - alpha) * cosine_decay + alpha
        return self.initial_lr * decayed * (m_mul ** cycle)

# Example usage with Adam optimizer
class AdamWithAdvancedScheduler(Adam):
    def __init__(self, scheduler, warmup_steps=1000, **kwargs):
        super().__init__(**kwargs)
        self.scheduler = scheduler
        self.warmup_steps = warmup_steps
        self.step_count = 0
        
    def update(self, params, grads):
        self.step_count += 1
        # Get learning rate from scheduler
        self.learning_rate = self.scheduler.cosine_decay_restart(
            self.step_count, 
            first_decay_steps=5000
        )
        return super().update(params, grads)

# Demonstration
scheduler = AdvancedLRScheduler(initial_lr=0.1)
steps = np.arange(20000)
lr_schedule = [scheduler.cosine_decay_restart(step, first_decay_steps=5000) 
               for step in steps]

plt.figure(figsize=(12, 4))
plt.plot(steps, lr_schedule)
plt.title('Cosine Decay with Warm Restarts')
plt.xlabel('Training Steps')
plt.ylabel('Learning Rate')
plt.grid(True)
plt.show()
