673
+ <p class="section-intro">
674
+ The cornerstone of this project. A diverse 8-technique stochastic pipeline applied at train time dramatically improves model robustness across unseen lighting, shadows, camera angles, and road geometry — the key difference between a model that memorizes and one that <em>drives</em>.

679
+ <p style="color:var(--muted);max-width:700px;margin:0 auto;font-size:.95rem;line-height:1.8">
680
+ Raw simulator data is heavily biased toward driving straight. Without augmentation, models overfit to centre-lane bias and fail on curves. Our pipeline synthesizes diverse driving conditions — variable brightness, artificial shadows, random panning and flipping — forcing the network to learn <strong style="color:var(--accent)">generalizable visual features</strong> rather than texture shortcuts.

1023
+ <p style="color:var(--muted);font-size:.9rem;line-height:1.7">ELU (Exponential Linear Unit) avoids the dying-neuron problem of ReLU. Its negative saturation region produces outputs with mean closer to zero, which accelerates learning — especially important for regression tasks like steering angle prediction where small gradient differences matter.</p>

Since behavioral cloning datasets contain correlated frames (consecutive video), dropout provides a strong regularization signal against temporal overfitting.</p>
