Sontrop, H.M.J. (author), Moerland, P.D. (author), Van den Ham, R. (author), Reinders, M.J.T. (author), Verhaegh, W.F.J. (author)Background: Large discrepancies in signature composition and outcome concordance have been observed between different microarray breast cancer expression profiling studies. This is often ascribed to differences in array platform as well as biological variability. We conjecture that other reasons for the observed discrepancies are the measurement...journal article 2009

(author)Motivation: Many enzymes are not absolutely specific, or even promiscuous: they can catalyze transformations of more compounds than the traditional ones as listed in e.g. KEGG. This information is currently only available in databases, such as the BRENDA enzyme activity database. In this paper, we propose to model enzyme aspecificity by...journal article 2009

Ten Holt, G.A. (author), Arendsen, J. (author), De Ridder, H. (author), Van Doorn, A.J. (author), Reinders, M.J.T. (author), Hendriks, E.A. (author)Current automatic sign language recognition (ASLR) seldom uses perceptual knowledge about the recognition of sign language. Using such knowledge can improve ASLR because it can give an indication which elements or phases of a sign are important for its meaning. Also, the current generation of data-driven ASLR methods has shortcomings which may...conference paper 2009

Shake-flask cultivation does not allow precise manipulation of individual culture parameters and therefore precludes a quantitative analysis of the (combinatorial) influence of these parameters on...journal article 2009

Van Nes, P. (author), Bellomo, D. (author), Reinders, M.J.T. (author), De Ridder, D. (author)In recent work, attempts have been made to link the structure of biochemical networks to their complex dynamics. It was shown that structurally stable network motifs are enriched in such networks. In this work, we investigate to what extent these findings apply to metabolic networks. To this end, we extend a previously proposed method by...journal article 2009

Hulsman, M. (author), Reinders, M.J.T. (author), De Ridder, D. (author)In recent years, more and more high-throughput data sources useful for protein complex prediction have become available (e.g., gene sequence, mRNA expression, and interactions). The integration of these different data sources can be challenging. Recently, it has been recognized that kernel-based classifiers are well suited for this task. However...journal article 2008

Hendriks, E.A. (author), Reinders, M.J.T. (author)Methods commonly used for speech and sign language recognition often rely on outputs of Hidden Markov Models (HMM) or Dynamic TimeWarping (DTW) for classification, which aremerely factorized observation likelihoods. Instead, we propose to use Statistical DTW (SDTW) only for warping, while classifying the synchronized features with either of two...conference paper 2008

Knijnenburg, T.A. (author), Wessels, L.F.A. (author), Reinders, M.J.T. (author)Motivation: Cells receive a wide variety of environmental signals, which are often processed combinatorially to generate specific genetic responses. Changes in transcript levels, as observed across different environmental conditions, can, to a large extent, be attributed to changes in the activity of transcription factors (TFs). However, in...journal article 2008

Wang, J. (author), Robertson, S. (author), De Vries, A.P. (author), Reinders, M.J.T. (author)Collaborative filtering is concerned with making recommendations about items to users. Most formulations of the problem are specifically designed for predicting user ratings, assuming past data of explicit user ratings is available. However, in practice we may only have implicit evidence of user preference; and furthermore, a better view of the...journal article 2008

Lichtenauer, J.F. (author), Hendriks, E.A (author), Reinders, M.J.T. (author)To recognize speech, handwriting, or sign language, many hybrid approaches have been proposed that combine Dynamic Time Warping (DTW) or Hidden Markov Models (HMMs) with discriminative classifiers. However, all methods rely directly on the likelihood models of DTW/HMM. We hypothesize that time warping and classification should be separated...journal article 2008

(author)Tumor formation is in part driven by DNA copy number alterations (CNAs), which can be measured using microarray-based Comparative Genomic Hybridization (aCGH). Multiexperiment analysis of aCGH data from tumors allows discovery of recurrent CNAs that are potentially causal to cancer development. Until now, multiexperiment aCGH data analysis has...journal article 2008

Van Vliet, M.H. (author), Klijn, C.N. (author), Wessels, L.F. (author), Reinders, M.J.T. (author)Background. The availability of large collections of microarray datasets (compendia), or knowledge about grouping of genes into pathways (gene sets), is typically not exploited when training predictors of disease outcome. These can be useful since a compendium increases the number of samples, while gene sets reduce the size of the feature space....journal article 2007
