What Makes AkashDrishti Different

Hover any capability to flip the card and read how it's engineered into the pipeline.

Adaptive Noise-Aware Preprocessing

Hover to reveal
Engineered into
Adaptive Noise-Aware Preprocessing

Engineered into the pipeline: classifies Gaussian, red, and instrumental noise per light curve, then routes it through the optimal denoiser — wavelet, Savitzky-Golay, or GP detrending.

Physics-Informed AI

Hover to reveal
Engineered into
Physics-Informed AI

Engineered into the model: Mandel-Agol transit priors, Kepler's third law, and limb-darkening constraints regularize the network so predictions stay astrophysically plausible.

Explainable Predictions

Hover to reveal
Engineered into
Explainable Predictions

Engineered into every verdict: SHAP attributions and saliency maps surface exactly which transit features drove the score — no black-box dispositions.

Confidence Calibration

Hover to reveal
Engineered into
Confidence Calibration

Engineered into the output layer: temperature scaling and isotonic regression ensure a stated 90% confidence really means 90% — critical for telescope-time triage.

Candidate Prioritization

Hover to reveal
Engineered into
Candidate Prioritization

Engineered into the ranking engine: multi-objective scoring weighs SNR, novelty, follow-up cost, and habitability to surface the highest-yield targets first.

Astronomer Decision Support

Astronomer Decision Support

Engineered into the UI: side-by-side periodograms, phase folds, and centroid checks give domain experts everything they need to confirm or reject a candidate.
