System, apparatus, and method for user tunable and selectable searching of a database using a weigthted quantized feature vector

The invention disclosed herein concerns a data processing means for user tunable and selectable searching of a database wherein the data contained therein have associated descriptive properties capable of being expressed in numeric form. A quantized vector representative of the descriptive properties is created for each item in the database. This quantized vector becomes the fingerprint for each data item. The user submits a query item to be matched against the database for similarity. A fingerprint is calculated for the query item. The user may then assign weights to the individual descriptive properties based upon perceived importance. A newly weighted fingerprint for the query item is then compared with the weighted fingerprints for all the data in the database. A list of results sorted in order of decreasing similarity is presented to the user. The user may then change the previously assigned weights and then re-run the similarity search. This may be done as often as necessary to achieve the desired results. The invention describes similarity searching in a generic database. However, this invention is particularly desirable in databases containing chemical compound structure data or biological response screening result data. The process described herein may be run stand alone or as a preliminary screening search in a large database. If used for screening, it can greatly reduce the amount of data required for exactly matching a query item to the data in the database.

De-noising method of transient electromagnetic detecting echo signal

The invention provides a de-noising method of a transient electromagnetic detecting receiving signal, which comprises the following steps of: decomposing a transient electromagnetic detecting receiving signal by means of empirical mode, i.e. 'screening'; leading all extreme points of signal data x (t) to form into an upper envelope and a lower envelope through a cubic spline interpolation function; obtaining a mean value m1, wherein a first component h1=x (t)-m1, and the h1 is regarded as data to be processed to repeat the screening with k times; obtaining a first IMF when the standard deviation SD of the continues twice screening results meets the requirement, wherein c1=h1k=h1(k-1)-m1k and a residual signal r1; repeatedly 'screening' the r1; decomposing signal data to be n IMFs and one residual quantity rn; judging signal dominant and noise dominant component according to the diminishing condition of each IMF energy; and accumulating again after filtering each IMF of the signal dominant to obtain the de-noised signal. The method adopts empirical mode decomposition of adaptive time-frequency analysis, does not need priori information, respectively processes the different natural frequencies of the signal, removes high-frequency noise, filters high-frequency noise, is applied to removing the noise of the non-linear and non-stationary transient electromagnetic detecting echo signal, and is patricianly applied to removing the noise of a deep echo signal.

System, apparatus, and method for user tunable and selectable searching of a database using a weighted quantized feature vector

A data processing means for user tunable and selectable (FIG. 2) of a database wherein the data contained therein have associated descriptive properties (FIG. 2) capable of being expressed in numeric form is described. Descriptive property values (FIG. 2) may be standardized numerically to eliminate property value overweighting. A quantized vector (FIG. 2) representative of the descriptive properties is created for each item in the database. This quantized vector becomes the fingerprint for each data item. The user submits a query item to be matched against the database for similarity. A fingerprint is calculated for the query item. The user may then assign weights to the individual descriptive properties based upon perceived importance (FIG. 2). A newly weighted fingerprint for the query item is then compared with the fingerprints for all the data in the database. A list of results is presented to the user (FIG. 2). The user may then change the previously assigned weights and then re-run the similarity search. This may be done as often as necessary to achieve the desired results. Similarity searching in a generic database is described. However, particulary the method is desirable in databases containing chemical compound structure data or biological response screening result data.
