+t-Distributed Stochastic Neighbor Embedding (t-SNE)
+---------------------------------------------------
+
+t-SNE is a nonlinear dimensionality reduction algorithm used for visualizing
+high-dimensional data in a lower-dimensional (usually 2D or 3D) space.
+
+It models pairwise similarities between points in both the high-dimensional
+and low-dimensional spaces, and minimizes the difference between them using
+gradient descent.
+
+This simplified implementation demonstrates the core idea of t-SNE for
+educational purposes — it is **not optimized for large datasets**.
+
+This implementation:
+- Computes pairwise similarities in the high-dimensional space.
+- Computes pairwise similarities in the low-dimensional (embedding) space.
+- Minimizes the Kullback-Leibler divergence between these distributions
+  using gradient descent.
+- Follows the original t-SNE formulation by van der Maaten & Hinton (2008).
+

+Explanation of Input and Output
+--------------------------------
+
+Input:
+- data_x: numpy array of shape (n_samples, n_features)
+  Example: Iris dataset (150 samples × 4 features)
+- n_components: target dimension (usually 2 or 3)
+- learning_rate: gradient descent step size
+- n_iter: number of iterations for optimization
+
+Output:
+- y: numpy array of shape (n_samples, n_components)
+  Each row is the low-dimensional embedding of the corresponding high-dimensional point.
+
+How it works:
+1. Compute high-dimensional similarities (p matrix)
+2. Initialize low-dimensional map (y) randomly
+3. Compute low-dimensional similarities (q matrix)
+4. Minimize KL divergence between p and q using gradient descent
+5. Update y with momentum and learning rate iteratively
