PARAFAC2 for semiconductor etch analysis

Component models have been used to detect errors in semiconductor etch processes [WGB+99], where the datasets have three natural modes: sample, measurement and time. However, the time required for measuring different samples may vary, which leads to a stack of matrices, one for each sample. This makes PARAFAC2 a natural choice [WGM01], as it naturally handles time profiles of different lengths.

In this example, we repeat some of the analysis from [WGM01] and show how total variation (TV) regularization can reduce noise in the components. TV regularization is well suited for reducing noise without overly smoothing sharp transitions [ROF92].

Setup

import matplotlib.pyplot as plt
import numpy as np
from tensorly.decomposition import parafac2

from matcouply.data import get_semiconductor_etch_machine_data
from matcouply.decomposition import parafac2_aoadmm

Data loading and preprocessing

train_data, train_metadata, test_data, test_metadata = get_semiconductor_etch_machine_data()

Loading semiconductor etch data from Wise et al. (1999) - J. Chemom. 13(3‐4), pp.379-396.

The dataset contains three experiments (experiments 29, 31 and 33). In [WGM01], the authors highlight the components obtained for experiment 29, so let’s look at the same experiment.

dataset_29 = [key for key in train_data if key.isnumeric() and key.startswith("29")]
matrices = [train_data[key].values for key in dataset_29]

Before analysing, we apply the same preprocessing steps as in [WGM01] — centering and scaling each matrix based on the global mean and standard deviation.

stacked = np.concatenate(matrices, axis=0)
mean = stacked.mean(0, keepdims=True)
std = stacked.std(0, keepdims=True)
standardised = [(m - mean) / std for m in matrices]

Fit a PARAFAC2 model

Let’s begin by fitting an unregularized PARAFAC2 model using the alternating least squares algorithm [KTBB99] with the implementation in TensorLy [KPAP19]. This algorithm is comparable with the one used in [WGM01].

We also impose non-negativity on the \(\mathbf{A}\)-matrix to handle the special sign indeterminacy of PARAFAC2 [Har72]. The \(\mathbf{A}\)-matrix elements in [WGM01] are also non-negative, so this shouldn’t change the components.

Similarly as [WGM01], we extract two components.

pf2, rec_err = parafac2(
    standardised, 2, n_iter_max=10_000, return_errors=True, nn_modes=[0], random_state=0, tol=1e-9, verbose=True
)

We examine the results by plotting the relative SSE and its relative change as a function of iteration number

it_num = np.arange(len(rec_err)) + 1
rel_sse = np.array(rec_err) ** 2

fig, axes = plt.subplots(1, 2, figsize=(10, 3), tight_layout=True)
axes[0].plot(it_num, rel_sse)
axes[0].set_ylim(0.67, 0.68)
axes[0].set_xlabel("Iteration number")
axes[0].set_ylabel("Relative SSE")

axes[1].semilogy(it_num[1:], (rel_sse[:-1] - rel_sse[1:]) / rel_sse[:-1])
axes[1].set_xlabel("Iteration number")
axes[1].set_ylabel("Relative change in SSE")
axes[1].set_ylim(1e-9, 1e-6)

plt.show()

Next, we look at the components

weights, (A, B, C), P_is = pf2
B_is = [P_i @ B for P_i in P_is]

# We normalise the components to make them easier to compare
A_norm = np.linalg.norm(A, axis=0, keepdims=True)
C_norm = np.linalg.norm(C, axis=0, keepdims=True)
A = A / A_norm
B_is = [B_i * A_norm * C_norm for B_i in B_is]
C = C / C_norm

# We find the permutation so the first component explains most of the variation in the data
B_norm = np.linalg.norm(B, axis=0, keepdims=True)
permutation = np.argsort(weights * A_norm * B_norm * C_norm).squeeze()

fig, axes = plt.subplots(1, 2, figsize=(16, 5))

for i, B_i in enumerate(B_is):
    axes[0].plot(B_i[:, permutation[0]], color="k", alpha=0.3)
    axes[1].plot(B_i[:, permutation[1]], color="k", alpha=0.3)

We see that the components are similar to those in [WGM01]. We can see an overall shape, but they are fairly noisy.

Note

In this simple example, we only use one random initialisation. For a more thorough analysis, you should fit several models with different random initialisations and select the model with the lowest SSE [YB21].

Next we use PARAFAC2 ADMM to apply a TV penalty

Since the TV-penalty scales with the norm of the factors, we also need to penalise the norm of \(\mathbf{A}\) and \(\mathbf{C}\) [RSC+22]. In this case, we use unit ball constraints, constraining the columns of \(\mathbf{A}\) and \(\mathbf{C}\) to have unit norm.

Similar as before, we add non-negativity on \(\mathbf{A}\) to resolve the sign indeterminacy.

Note

The proximal operator for the total variation penalty is computed using the C-implementation for the improved version of the direct TV algorithm presented in [Con13]. The C-implementation is CeCILL lisenced and is available here, and the Python-wrapper, condat-tv, is GPL-3 lisenced and is available here.

converged in 357 iterations: FEASIBILITY GAP CRITERION AND RELATIVE LOSS CRITERION SATISFIED

We examine the diagnostic plots

For ALS, the relative SSE and its change was the only interesting metrics. However, with regularized PARAFAC2 and AO-ADMM we should also to look at the feasibility gaps and the regularization penalty.

All feasibility gaps and the change in relative SSE should be low.

rel_sse = np.array(diagnostics.rec_errors) ** 2
loss = np.array(diagnostics.regularized_loss)
feasibility_penalty_A = np.array([gapA for gapA, gapB, gapC in diagnostics.feasibility_gaps])
feasibility_penalty_B = np.array([gapB for gapA, gapB, gapC in diagnostics.feasibility_gaps])
feasibility_penalty_C = np.array([gapC for gapA, gapB, gapC in diagnostics.feasibility_gaps])

it_num = np.arange(len(rel_sse))

fig, axes = plt.subplots(2, 3, figsize=(15, 6), tight_layout=True)
axes[0, 0].plot(it_num, rel_sse)
axes[0, 0].set_ylim(0.69, 0.71)
axes[0, 0].set_xlabel("Iteration number")
axes[0, 0].set_ylabel("Relative SSE")

axes[0, 1].plot(it_num, loss)
axes[0, 1].set_xlabel("Iteration number")
axes[0, 1].set_ylabel("Regularized loss")

axes[0, 2].semilogy(it_num[1:], np.abs(loss[:-1] - loss[1:]) / loss[:-1])
axes[0, 2].set_xlabel("Iteration number")
axes[0, 2].set_ylabel("Relative change in regularized loss")

axes[1, 0].semilogy(it_num, feasibility_penalty_A)
axes[1, 0].set_xlabel("Iteration number")
axes[1, 0].set_ylabel("Feasibility gap A")

axes[1, 1].semilogy(it_num, feasibility_penalty_B)
axes[1, 1].set_xlabel("Iteration number")
axes[1, 1].set_ylabel("Feasibility gap B_is")
axes[1, 1].legend(["PARAFAC2", "TV"])

axes[1, 2].semilogy(it_num, feasibility_penalty_C)
axes[1, 2].set_xlabel("Iteration number")
axes[1, 2].set_ylabel("Feasibility gap C")

Text(1025.2772062174477, 0.5, 'Feasibility gap C')

Next, we look at the regularized components

weights, (A, B_is, C) = cmf
# We find the permutation so the first component explains most of the variation in the data
B_norm = np.linalg.norm(B_is[0], axis=0, keepdims=True)  # All B_is have same norm due to PARAFAC2 constraint
permutation = np.argsort(B_norm).squeeze()

fig, axes = plt.subplots(1, 2, figsize=(16, 5))

for i, B_i in enumerate(B_is):
    axes[0].plot(B_i[:, permutation[0]], color="k", alpha=0.3)
    axes[1].plot(B_i[:, permutation[1]], color="k", alpha=0.3)

We see that the TV regularization removed much of the noise. We now have piecewise constant components with transitions that are easy to identify.

Comparing with unregularized PARAFAC2

print("Relative SSE with unregularized PARAFAC2: ", rec_err[-1] ** 2)
print("Relative SSE with TV regularized PARAFAC2:", diagnostics.rec_errors[-1] ** 2)

Relative SSE with unregularized PARAFAC2:  0.6706095457399559
Relative SSE with TV regularized PARAFAC2: 0.6945922121734127

We see that there is only a small change in the relative SSE, but the components are much smoother and the transitions are clearer.
