Neural-Network–Based Continuum Background Inpainting for COSI

Overview

This notebook provides an introduction to neural-network–based background inpainting for COSI data using the ContinuumEstimationNN class in cosipy. The purpose of this tutorial is to demonstrate how machine learning methods can be used to estimate the continuum background. Specifically, here we use a graph-based convolutional neural network. This approach trains a neural network in order to reconstruct (inpaint) the background for regions of the Compton data space (CDS) occupied by a source of interest (currently only tested for point sources). The resulting background estimate can be used directly in COSI analysis.

What This Method Does

At a high level, the inpainting procedure consists of the following steps:

Project COSI data into the 3D CDS spanned by measured energy (Em), Compton scatter angle (Phi), and sky coordinates (PsiChi)
Mask region in the CDS dominated by a point source using the point source response and angular resolution measure (ARM).
Train a neural network on the unmasked sky pixels
Predict the background in the masked region and merge the result with the observed data

The sky is discretized using HEALPix, which naturally defines a graph where each pixel is connected to its neighbors. This allows the neural network to propagate information across the sphere while respecting the underlying sky geometry.

Training Modes

The inpainting algorithm supports three complementary training modes:

Self-supervised (default)

No background model is required. The network learns by randomly masking a fraction of the sky and training itself to reconstruct those pixels.
Supervised

A background model is provided and treated as ground truth in the masked regions.
Hybrid

A weighted combination of supervised and self-supervised training. This mode leverages an existing background model while remaining robust to modeling uncertainties.

The training mode is selected with a single keyword argument, making it easy to experiment with different strategies.

Neural Network Architecture

Two graph-based neural network architectures are available:

GCN (Graph Convolutional Network)

A lightweight, four-layer architecture optimized for stability and speed.
Graph U-Net

A deeper architecture that captures larger-scale structure through pooling and unpooling operations.

Both models operate directly on HEALPix graphs and are implemented using PyTorch Geometric. GPU acceleration is used automatically when available, but the method also runs on CPUs for smaller datasets and testing.

Outputs and Diagnostics

This workflow produces:

Inpainted background histogram: compatible with cosipy
Mollweide sky maps: optional, showing the true, masked, and inpainted data for a given bin of Em and Phi
Training-loss diagnostics: saved during optimization
Accuracy evaluation plots: when a reference background model is available

These diagnostics are designed to help assess both the quality of the final background estimate and the behavior of the neural network during training.

Limitations of the Method

The source region in the CDS is masked based on the ARM. However, for the COSI response, the ARM of a source has a long tail. This limits the accuracy of the estimated background, since the source photons in the tail cannot be masked.

In terms of training the network, most of the infrastructure is in place. However, further development is needed to optimize the network and training.

Tutorial Outline

There are three main parts to this tutorial. First, we will demonstrate the basic functionality of the continuum background estimation class, and use it to get an estimate of the background using the GCN method. Then, instead of a NN-based algorithm, we’ll estimate the background using a simple interpolation method (same as was used for DC3). Finally, we will then use the estimated background to perform a spectral fit. This example uses the Crab and total background from DC3.

There is a convenience function that allows you to run the background estimation algorithm with a single command. The command is shown below with all available options. At minimum, you need to pass the input data and point source response file. All optional inputs are shown with their default values, except for epochs, which we set to 1 in order to speed up the runtime. See cosipy documentation for more information on the input parameters.

Note: this example notebook is being run with 1 GPU. The code detects this automatically and will utilize GPU acceleration. If no GPUs are detected it will default to CPU.

Producing the estimted BG map took 604.5 seconds (10.1 minutes). From the diagnostic plots, we see that the agreement with the model is generally within 1% (when projected onto a given axis).

Let’s now take a look at the training loss for one of the energy bins:

[6]:

for E in range(2,3):
    instance.plot_training_loss("inpainting_nn_model_training_loss.npy",E,"training_loss",vmax=70000)

The NN model is saved, including the weights, optimizer state, epochs, and training loss. Let’s run the estimate again, but this time we’ll laod the model from file. We just want to demonstrate the funcionality here, and so we’ll set epochs to 1.

Estimating the background with simple interpolation inpainting

Instead of NN-based inpainting, we can also do a simple interpolation. This is the original method presented with DC3, and it’s useful as a baseline to gauge the improvement from the NN-based method. For each masked pixel, the algorithm moves to the left till it finds the first non-masked pixel, and then moves to the right till findinging the first non-masked pixel. The inpainted value is taken as the mean of left and right. This is easy to implement because we have a healpix skymap in ring order. All other methods are inhereted from the ContinuumEstimationNN class. Let’s run it:

instance = ContinuumEstimationInterp()

The agreement seems to be a bit worse compared to the NN-based method (within ~2%).

Spectral fit using the estimated background

This example is nearly identical to the spectral fit example in docs/api/interfaces/examples/crab. The main difference is that instead of the ideal BG file, we will use the estimated BG calculated in the previous section.

input: norm = 3.07e-5

estimated BG NN: norm = (3.243 +/- 0.009)e-5, logL = 1591385619.4884508

estimated BG simple: norm = (3.589 +/- 0.009)e-5, logL = 1591401274.5105834

ideal BG: norm = (2.927 +/- 0.009)e-5, logL = 1591705157.1250365

Comparing estimated BG (simple) to true BG: \(2 \Delta \mathrm{logL}\) = 607765.2 \(\implies \sigma = 780\) (true BG is preferred)

Comparing estimated BG simple to GCN: \(2 \Delta \mathrm{logL}\) = 31310.0 \(\implies \sigma = 177\) (simple inpainting is preferred)

Thus, the ideal BG performs significanlty better than the estimated, as expected. The NN estimate gives a normalization closer to the true value. The counts also look better at most energies (except for the last 2 bins). However, the simple alogirthm gives a significantly better TS compared to the NN-based inpainting. The next step is to improve the estimation algorithm to get closer to the ideal BG.
