Mapping spatial & temporal metrics derived from Simulated DataRobert Frank, Haishan Liu, Gwen Frishkoff, & Dejing Dou

Dataset: SDv5 (P1N1N3MFNP3-SDv5 datasets)
1. STUDY GOALS & SUMMARY OF METHODS AND RESULTSThe goal of this study was to explore methods for identifying correspondences (“mappings”) between different spatial and temporal metrics that are used to summarize ERP patterns.
The data for this study comprised 80 simulated ERP datasets representing 40 subjects in 2 experimental conditions. Each ERP dataset was generated by the superposition of 5 patterns with unique spatiotemporal characteristics representing distinct neuronal groups: the P100, N100, N3, MFN and P300, Inter-subject and inter-conditional variance were induced by modulating pattern intensity across datasets.
Spatiotemporal components from the temporal PCA (tPCA) and spatial ICA (sICA) decompositions of this simulated data were assessed and labeled using pattern rules that quantified the spatial and temporal characteristics of their respective patterns. The component that most frequently captured each pattern across subjects and conditions was labeled as the modal component for that pattern and subjected to further analysis.
Overview of data processing steps:1. Decomposition -- why we selected tPCA and sICA (vs. sPCA). Relevant question for mapping work:
sensitivity of mapping methods to distribution of measures for spatial vs. temporal metrics. [part since there are many more spatial than temporal metrics, which could bias the method]
2. Selection of modal factors/components for each latent pattern and autolabeling of observations (match vs. mismatch)
3. Generation of alternative sets of spatial and temporal metrics. Note about why onset, offset, and duration were not used for this study.
4. Clustering of instances (matches for modal factors) -- for validation and refinement, to align sets of observations with (latent) pattern labels. Post-processing of clusters to align latent patterns. [explain what this accomplishes that autolabeling by itself does not -- i.d. observations that do not represent simple structure, weed these out... ]
5. Mapping across metrics. Explain advantages of this procedure over simple correlation of means & s.d. across observations within each pattern.

*-- signifies that observations in these clusters were assigned to more than one pattern/rule. See Section 2.6 for details.
Note that the assignment of observations to clusters, and the corresponding splitting of observations of a single pattern into two or more clusters on some occasions, is a function of the metrics used to generate the dimensions and axis orientations of the multidimensional attribute space. Observations that are close in L2 norm along one dimension of a spatiotemporal attribute space may be farther away in L2 norm on a separate dimension of an alternate attribute space instantiated by an alternate metric set. This is consistent with mathematical topology, in which mathematical objects that are close in one topology, or one generalized measure of distance, can be far apart in another topology, or an alternate measure of distance. This phenomena is also present in the expert labeling of observations, as changes to expert-defined pattern rules redefine observation to pattern mappings and may reshuffle observation labels.
2. SIMULATED DATASETSTo generate the simulated data for this experiment, we first designed two ERP datasets, each of which comprised 40 ERPs from 20 simulated subjects in 2 experimental conditions: SDv5_SG01 and SDv5_SG02. The ERPs in each dataset are superpositions of 5 simulated ERP patterns as defined in the SDv5 protocol and described in Section 2.1. We then generated 4 new datasets by separately applying sICA and tPCA to the 40 ERPs in each of the two 20-subject groups, Two alternative metric sets, m1 and m2, were applied to these 4 PCA/ICA derived datasets to quantify the spatiotemporal characteristics of their corresponding tPCA factors and sICA components. Thus, the computed metric values summarize the spatiotemporal characteristics of the original subject and condition specific simulated ERPs as now represented by their respective PCA and ICA decompositions. These final 8 sets of extracted spatiotemporal attributes form the input datasets for the subsequent evaluation and labeling procedures. Table 2 gives an overview of the dataset design:

2.1 Simulated data design and creation
The simulated ERP datasets for this study were generated using the August 2007 release of Dipole Simulator, which employs a 3-shell spherical head model. We used the application’s default conductivity values for each shell in modeling the propagation of source dipole activity to the spherical scalp surface.
Nine dipoles were carefully located and oriented within a 3-shell spherical model to simulate the topographies of 5 ERP components commonly seen in studies of visual word recognition: the P100, N100, N3, MFN and P300. Each dipole was then assigned an activation profile consistent with the polarity and time course of its respective ERP component. Simulated “scalp-surface” electrode locations were specified with an EGI HC-GSN 129-channel montage. Owing to volume conduction and the overlap of their temporal activity, the dipole activations induce a complex spatial and temporal superposition of the 5 modeled ERP patterns on the volume boundary. This simulated EEG data were recorded by computing the resultant surface intensities of the dipole activations at 129 channel locations for 600 milliseconds, or 150 samples at a 250 Hz sampling rate (Figure 1). The baseline location and orientation of each dipole are listed in Table 3. Table 4 lists corresponding ERP pattern latency (onset, offset, and peak) and surface peak-intensity baseline values, and inter-subject and inter-condition baseline offsets.

The first 8 dipoles are grouped into 4 laterally symmetric pairs, representing the P100, N100, N3 and P300 components. The remaining medially-located 9th dipole models the frontal MFN.

Note: Subject and condition offsets specify the mean (if applicable) and standard deviation of a normal distribution from which perturbations to peak electrode intensity (uv) and latency (ms) baseline values are drawn.
Following Dien, Khoe, and Mangun (2007), we quantified the degree of spatial and temporal correlation of these 4 patterns. Our goal was to generate pattern combinations with different spatiotemporal characteristics to test the efficacy of data decomposition methods (tPCA, sPCA, sICA, Microstate Analysis, …) for separation of ERP patterns in the presence of different degrees of spatial and temporal interaction.

By adding small perturbations in pattern intensity to the baseline ERP pattern parameters, pursuant to the ERP_Dipole_Specs-v14.xls spreadsheet, we simulated two groups of "subject"-specific ERPs (20 subjects/group) under the first experimental "condition", for a total of 40 condition # 1 simulated ERPs. Perturbations of the ERP pattern intensities were drawn from a normal distribution with zero mean and pattern-specific standard deviations, as listed in the Subject Offset column of Table 4.
Perturbing the spatiotemporal properties of the ERP patterns that constitute the 40 "subject"-specific ERPs generated under condition #1 results in a second dataset containing, for each “identical” subject, distinct ERPs generated under experimental condition #2. In accordance with pattern rules, the intensity of the ERP patterns that constitute each subject-specific condition #1 ERP were altered to establish their corresponding condition #2 ERP. Perturbations of the ERP pattern intensities were drawn from normal distributions with pattern-specific mean and standard deviations, as listed in the Condition Offset column of Table 4.
Simulated noise was added to try to give the data some of the properties of background EEG (Dipole Simulator 3.2.0.3, Patrick Berg 2001 – 2009):
The noise is coherent in the sense that there is quite a high correlation between signal amplitudes from electrodes that are close together.
There is some attempt to emulate the frequency characteristics of EEG, with added weighting around 10 Hz, although the 10 Hz signal does not show the characteristic occipital-parietal dominance.
The noise is defined using the following steps: The waveform generated in the program is assumed to consist of 150 time points, sampled at 100 Hz,
representing an interval of 1.5 s. 200 random sources are generated subject to the following restrictions:
6
1. eccentricity lies between 0.6 and 0.7 of the head radius2. location is not below 0.5 of the head radius below the sphere center.
3. orientation is random. For each source, its waveform is defined in frequency space:
1. Based on a 256 time point waveform, at each of the 256 frequencies, the phase is selected at random. The amplitude at each frequency is constant.
2. The resulting frequencies are weighted by the function 1/Öf where f is the frequency, defined as a number between 1 and 256, and an additional function which adds a cosine window from 7 to 13 Hz (maximum at 10 Hz), in order to simulate alpha. The cosine window is weighted by a factor between 0 and 1 which determines the alpha level. This factor is adjusted in the program.
3. Using an inverse fft (Fast Fourier Transform), the frequencies are converted to a waveform. The first 150 time points are used.
For each source, the data waveform at each electrode is generated. For each electrode, data waveforms are summed over the contributions from all 200 sources.
Over all waveforms and electrodes, the average referenced data are scaled to unit standard deviation. These noise data are then added in the user-specified proportion to the dipole simulated data.

2.2 tPCA and sICA decompositions
Temporal PCA (tPCA) and spatial ICA (sICA) were chosen to decompose the simulated ERP data. tPCA and sICA respectively utilize 2nd and higher-order data statistics to separate spatially and temporally overlapping patterns onto discrete rank-1 spatiotemporal components, facilitating their identification and labeling. These particular variants of PCA and ICA were chosen because they are compatible with the high degree of spatial correlation, arising from volume conduction, that is common to many ERP patterns
We implemented tPCA and sICA with Dr. Joseph Dien’s PCAToolbox, v1.092. For tPCA, the 18 lead tPCA eigenvectors from each subject group’s temporal data covariance matrix underwent a subsequent Varimax rotation and Promax relaxation. The Varimax rotation extracts components with compact time courses, while the Promax relaxation removes the spatial orthogonality constraint. 18 eigenvectors were chosen because they accounted for ~ 90% of the data’s variance, consistent with the simulated ERP dataset design in which the simulated patterns accounted for the majority of the variance, with added noise composing the rest. A scree plot of cumulative variance versus retained eigenvectors validated this choice.
The sICA used the Infomax algorithm applied to the temporally concatenated ERPs of each subject group. 18 independent components were retained because they again accounted for the majority (> 90 %) of the data’s variance and because this choice was consistent with the tPCA procedure.

2.4 Five (5) Pattern Rules used for Autolabeling of SDv5 DataThe input to the clustering consists of labeled data (attribute vectors) for 5 patterns: P100, N100, N3, MFN and P3. For these studies, the data (each subject-, condition-, and tPCA/sICA factor-specific observation) were labeled by PCAautolabel pursuant to ERP pattern rules as defined in Simulated_ERP_Rules_2008-05-06 (corrected).doc*. The 5 rules are:
Rule #1 (pattern PT1 = P100-visual “component” of the ERP)Let ROI=occipital (average of left occipital, right occipital)For any n, FAn = PT1 iff
70ms < TI-max (FAn) ≤ 140ms AND temporal criterion #1 |IN-mean(ROI)| ≥ .4 mV AND min variance criterion IN-mean(ROI) > 0 spatial criterion #1
Rule #2 (pattern PT2 = N100-visual “component” of the ERP)Let ROI=occipital (average of left occipital, right occipital)For any n, FAn = PT2 iff
141ms < TI-max (FAn) ≤ 220 ms AND temporal criterion #2 |IN-mean(ROI)| ≥ .4 mV AND min variance criterion IN-mean(ROI) < 0 spatial criterion #2
Rule #3 (pattern PT2 = N3 “component” of the ERP)Let ROI= left and right frontalFor any n, FAn = PT2 iff

401ms < TI-max (FAn) ≤ 600ms AND temporal criterion #3 |IN-mean(ROI)| ≥ .4 mV AND min variance criterion IN-mean(ROI) > 0 spatial criterion #3
* Simulated_ERP_Rules_2008-05-05.doc specified initial PCAautolabel ERP pattern rules. Observations were subsequently labeled according to ERP pattern rules as specified in Simulated_ERP_Rules_2008-05-06 (corrected).doc to improve factor / pattern correspondence.

**GF: Note that for Rule 3, there are matches to the pattern rule for observations belonging to more than one factor. This may create a problem for analysis if all pattern matches are included in the clustering. In particular, it violates our (expert) goal of using PCA to find a “simple structure” (pattern-to-factor mapping) in the data. To simplify matters for these case studies, we have therefore selected only pattern matches (i.e, observations) belonging to what we call the “modal factor.” The “modal factor” is typically the factor that has the highest percentage of observations matching the pattern rule.

2.5. Clustering of the 8 simulated ERP datasetsThe number of clusters was not constrained.Only those observations that belonged to the 5 modal factors were used in the clustering. Hence, the total N for each dataset that was input to clustering was ~190–195 (out of 200 total observations).
The following run information gives the settings for clustering of these data in WEKA using the EM algorithm.

Note that the assignment of observations to clusters, and the corresponding splitting of observations of a single pattern into two or more clusters on some occasions, is a function of the metrics used to generate the dimensions and axis orientations of the multidimensional attribute space. Observations that are close in L2 norm along one dimension of a spatiotemporal attribute space may be farther away in L2 norm on a separate dimension of an alternate attribute space instantiated by an alternate metric set. This is consistent with mathematical topology, in which mathematical objects that are close in one topology, or one generalized measure of distance, can be far apart in another topology, or an alternate measure of distance. This phenomena is also present in the expert labeling of observations, as changes to expert-defined pattern rules redefine observation to pattern mappings and may reshuffle observation labels.

2.7 Mapping Result5 sampling of random ordering is performed on each cross subject group, metric set mapping study. The mapping result is represented by the selected columns. E.g. the golden standard mapping should be found at the following column indices: 1 2 3 4 5 6 7 8 9 10 11 12 13, indicating the cells at locations (1,1), (2,2), (3,3) …

3. MAPPING
After clustering of instances according to their pattern labels, the instances are then aligned across datasets using the pattern labels, which results in a subsequence reordering. As illustrated in the right-hand graphs in Figure 2, the point-sequence curves for metrics IN-O1 and IN-LOCC are manifestly more similar after reordering subsequences in the two curves by aligning instances that belong to the same (or similar) patterns.
Figure 2: Left, IN-LOCC and IN-O1 point-sequence curves prior to grouping and reordering. Right, Labeled point-sequence curves for metrics IN-O1 and IN-LOCC after grouping and reordering points with the same labels.
After ontology-based alignment of the subsequences, we carried out three pre-processing steps: (1) Normalization, i.e., scaling all the sequence values to unit range; (2) Smoothing using a moving average method; and (3) Interpolation of curves if the number of points in two point-sequence curves (for two value vectors) is different. Figure 3 illustrates the results of normalization, smoothing and interpolation to the point-sequence curves of IN-O1 and IN-LOCC in Figure 3.

The following heuristic assumptions are adopted in our sequence matching procedure.
68
First, we assume that the two datasets from which these alternative metrics are extracted contain the same or similar ERP patterns. This assumption is critical, since we seek to align ERP patterns (clusters) across the two point-sequence curves.
Second, we assume there exists a 1-to-1 mapping between pairs of metrics from the alternative sets of metrics. In other words, there must be no cells selected within the same column.
Table 1. Violation of 1-1 mapping assumption and the solution.
For example, Table 1(a) illustrates a scenario where the 1-to-1 mapping assumption is violated: if we select cells with minimum distance value in each row, we end up with two cells within the same column being selected, which in the present case would suggest that both IN-LOCC and IN-ROCC are mapped to IN-O2. Table 1(b) illustrates the solution: cells are selected using the 1-to-1 mapping heuristic coupled with the global minimum heuristic.
Finally, we assume a global minimum heuristic: we select those cells whose Euclidean distance values sum up to a minimum value.

Table 2. Solution to A using global minimum heuristic
For example, Table 2 shows two alternative selections of cells without violating to the 1-to-1 mapping heuristic. The global minimum heuristic requires us to favor 2(b) because 4.08+3.57 < 3.74+4.01. The selection of cells that achieves the global minimum suggests the most stable mapping result. The global minimum heuristic requires a non-greedy implementation which should take into consideration all possible selections. When the number of metrics is large, this implementation becomes more computationally challenging.
The experiment is conducted on the simulated datasets described in Section 3.1. The test cases for the matching discovery experiment are derived as follows: each test case contains a source and target dataset, which are pulled respectively from one subject group characterized with one metric set, and from the other

subject group with the alternative metric set; both the source and target are formulated under the same decomposition method. This yields four test cases, each of which includes two different datasets and two alternative metric sets.
In order to test the robustness of the proposed methods, we replicate the datasets for each test case into five copies with different random ordering of the instances, thus resulting a total of 20 enriched test cases. We test our method on each of these test cases. Table 3, for example, shows a distance table calculated by cross-spatial join of tPCA-derived data from SG01-m1 and SG02-m2. The highlighted cells indicate similarity pairs between two point-sequence curves representing two metrics (row header and column header which meet at this cell) and are selected by using the 1-to-1 mapping and global minimum heuristics described in Section 3.5. A similarity pair represents a potential mapping discovered by our methods.
For example, from this table we derive the following mappings: IN-O1↔ IN-LOCC, IN-O2↔IN-ROCC, IN-C3↔IN-LPAR, etc. Note that the row header and column header are arranged in the particular order such that the golden standard mapping falls along the diagonal cells. Therefore we can easily conclude that the precision of mapping in this test case is 9/13=69.2% since 4 out of 13 highlighted cells are shifted off from the diagonal.
The performance of our methods among the 20 test cases was quite good. Table 3 summarizes the precision for each test case.

The table consists of four quadrants, each of which illustratess precision mesure for the datasets generated by five samples of replication to the original four test schemes with random instance ordering. Since the precision of mapping by making a random guess in each test case is almost zero, the precision of our method appears markedly robust.
Combining the mapping results in the 20 test cases into an ensemble model by a majority vote of each individual mapping result, we obtained the ensemble mapping result shown in Figure 4. The overall result is 11/13=84.6%
