Fragmentation trees are a critical step towards elucidation of compounds from mass spectra by enabling high confidence de novo identification of molecular formulas of unknown compounds (doi:10.1186/s13321-016-0116-8). Unfortunately, those algorithms suffer from long computation times making analysis of large datasets intractable. Recently, however, Fertin et al. (doi:10.1016/j.tcs.2020.11.021) highlighted additional properties of fragmentation graphs which could reduce computational times. Since their work is purely theoretical and lacks an implementation, I'm looking to partner up with someone to investigate and implement faster fragmentation tree algorithms. Could end up being a nice paper. Anyone interested?

Question

A tunable clock source will consist of a PLL circuit like the Si5319, configured by a microcontroller. The input frequency is fixed, e.g. 100 MHz. The user selects an output frequency with a resolution of, say, 1 Hz. The output frequency will always be lower than the input frequency.
The problem: The two registers of the PLL circuit which determine the ratio "output frequency/input frequency" are only 23 bit wide, i.e. the upper limit of both numerator and denominator is 8,388,607. As a consequence, when the user sets the frequency to x, the rational number x/108 has to be reduced or approximated.
If the greatest common divider (GCD) of x and 108 >= 12 then the solution is obvious. If not, the task is to find the element in the Farey sequence F8388607 that is closest to x/108. This can be done by descending from the root along the left half of the Stern-Brocot tree. However, this tree, with all elements beyond F8388607 pruned away, is far from balanced, resulting in a maximum number of descending steps in excess of 4 million; no problem on a desktop computer but a bit slow on an ordinary microcontroller.
F8388607 has about 21*1012 elements, so a balanced binary tree with these elements as leaves would have a depth of about 45. But since such a tree cannot be stored in the memory of a microcontroller, numerator and denominator of the searched Farey element have to be calculated somehow during the descent. This task is basically simple in the Stern-Brocot tree but I don't know of any solution in any other tree.
Do you know of a fast algorithm for this problem, maybe working along entirely different lines?
Many thanks in advance for any suggestions!
Relevant answer
Answer
Now I tested the idea of jumping downwards in the Stern-Brocot tree. This idea is based on the observation that long paths from the root to a Farey element always seem to contain long sequences of steps directed exclusively to the left or exclusively to the right. As long as the direction is constant, the values of numerator and denominator which are added to the current node are also constant, obviously. Therefore, the products of numerator and a certain jump width resp. denominator and a this jump width can be added to the node.
In order to determine the largest possible jump width, bitwise successive approximation is used in this first approach. The result is quite satisfactory:
With an input frequency of 100 MHz, and the output frequency in the range 1 Hz to 100 MHz - 1 Hz (at the extrema, the approximation by Farey elements is poor, of course), the sum of the passes through the outer loop (movement through the tree) and through the inner loop (determining the maximum jump width) never exceeds 386. Attached is my C source. Compared to the maximum number of single steps, this is an improvement of 4 orders of magnitude.
While this approach solves my practical problem, I would still be interested in other solutions because sometimes it's amazing how a problem can be tackled in different ways.

I have in mind, that Logic is mainly about thinking, abstract thinking, particularly reasoning. Reasoning is a process, structured by steps, when one conclusion usually is based on a previous one, and at the same time it can be the base, the foundation of further conclusions. Despite the mostly intuitive character of the algorithm as a concept (even not taking into account Turing and Markov theories/machines), it has a step by step structure, and they are connected, even one would say that logically connected (when they are correct algorithms). The different is, of course, the formal character of the logical proof.

Answer
Teachable neural networks are currently the main direction in the development of artificial intelligence (AI). These systems belong to the category of inductive anthropomorphic, which is associated with their well-known advantages, disadvantages and areas of application. It is generally accepted that anthropomorphism is the exclusive factor in the advantage of AI, however, there are actual areas of AI application, in which the use of deductive systems is more effective, which use less data and computational resources, but are capable of learning. Examples of such systems: knowledge generators, expert systems, active marketing systems, and many others.
The basis of AI deductive imitation systems are extremely general models and algorithms that imitate the objects (objects) under consideration. The generality limit is determined both by the amount of knowledge about the object and by the calculated capabilities. General models (metamodels) are usually formed in the form of systems of equations that link together the variables that describe the object under consideration, as well as parameters that determine the form of partial equations formed when transforming the equations of the general model. The solution of such systems of equations is carried out by methods of global optimization: stochastic (Monte Carlo methods) or heuristic (evolutionary algorithms and others). Simulation AI presupposes the solution of two basic problems: inverse (implementing the system training options) - the formation of partial equations (models) according to the values ​​of certain variable characteristics of objects; direct - definitions of values ​​of variables for particular configurations of models. The use of simulation metamodels in combination with the randomization of variables and parameters provides high flexibility and adaptability of intelligent systems.

Any new innovations other than First-Come, First-Served (FCFS) / Shortest-Job-First (SJF)/ Round Robin (RR) or mix-development of those?
Relevant answer
Answer
A Process Scheduler is a program that distributes different tasks to the CPU based on different scheduling algorithms. Process scheduling can be done in six different ways.
There are three more algorithms besides First-Come, First-Served (FCFS) / Shortest-Job-First (SJF) / Round Robin (RR) or mix-development,
  • Priority Scheduling
  • Shortest Remaining Time
  • Multiple-Level Queues Scheduling
Priority Scheduling
Priority scheduling is a non-preemptive scheduling approach that is commonly employed in batch systems. Each process is assigned a priority. The most important procedure will be completed first, followed by the next most important step, and so on. Processes with the same priority are executed on a first-come, first-served basis. Memory requirements, time restrictions, or any other resource constraint can all influence prioritization.
Shortest Remaining Time
The SJN algorithm's preemptive version is the least remaining time (SRT).
The processor is allocated to the task that is closest to completion, but it may be surpassed by a newer ready project with a lower completion time. It is impossible to implement in interactive systems when the required CPU time is uncertain. It's commonly utilized in batch settings when short operations need to be prioritized.
Multiple-Level Queues Scheduling
Multiple-level queues aren't a viable scheduling option on their own. Using existing algorithms, they aggregate and schedule work of comparable quality. Each queue, for example, can have its own scheduling algorithms and be assigned a priority.

Interior point methods (https://en.wikipedia.org/wiki/Interior-point_method) are generally superior to active-set methods (https://en.wikipedia.org/wiki/Active-set_method) for solving large-scale problems.
You usually end up solving a convexified equality-constrained problem, that is a system of nonlinear equations. That's the most favorable case.
Among active-set methods, SLQP (https://en.wikipedia.org/wiki/Sequential_linear-quadratic_programming) is of particular interest. It also forms an equality-constrained quadratic problem (the favorable case) after it approximated the set of active inequality constraints by solving a linear problem.

It's no longer a surprise to realize a wide gap between advances in academic research and practicality in Industry. This discussion is about exploring this gap for a particular domain, which is Time-Series Forecast. The topic has had great many research advances in recent years, since researchers have identified promises offered by Deep Learning (DL) architectures for this domain. Thus, as evident in recent research gatherings, researchers are racing to perfect the DL architectures for taking over the time-series forecast problems. Nevertheless, the average industry practitioner remains reliant on traditional statistical methods for understandable reasons. Probably the biggest reason of all is the ease of interpretation (i.e. interpretability) offered by traditional methods, but many other reasons are valid as well, such as: ease of training, deployment, robustness, etc. The question is: If we were to reinvent a machine learning solution solely for industrial applicability, considering the current and future industry needs, then what attributes should this solution possess? Interpretability, Manipulability, Robustness, Self-maintainability, Inferability, online-updatability, something else?
Relevant answer
Answer
From my personal experience, Deep Learning (DL) offers NO substantial improvement in time series forecasting accuracy vs. traditional methods, such as Holt-Winters, exponential and double exponential smoothing with or without trends, Holt-Winters with seasonality and trends, autoregressive integrated moving average (ARIMA), digital filtering, etc.
Regardless of the concrete technique (including deep learning and recursive neural networks in AI), all time series forecasting methods are based on the use of the historical past data to extrapolate them into the future. The fundamental assumption of any forecasting technique (implicit or explicit) is that time series represents a stable pattern that can be identified and then extended into the future. If a pattern of the past data-points is not statistically stable, then no meaningful future prediction (forecasting) is possible regardless of the sophistication of the forecasting technique (DL or not).
It seems reasonable to assume that too ‘old’ data-points do not practically affect (correlated to) the most recent data-points, let alone the future data. The data-points that are strongly correlated to the newer ones can be used for making the forecast. The data-points that are weakly correlated to the newer ones (or not correlated at all) should not be included for forecasting; otherwise, the forecast will likely be skewed. Thus, the use of a large number of the available past data-points worth of several years of observations is not needed for making a meaningful forecast; in fact, the large number of the past data-points can be detrimental to producing a reasonably accurate forecast regardless of the used technique (deep learning or not). The problem of the optimal number of the past data points (training set size) of a time series should be the primary focus for industrial applicability of the forecasting rather than a forecasting technique (DL or not).

Relevant answer
Answer
Hi Kabir,
Your example dataset just shows satellite haplotypes differing by a single mutation from the reference. It's nothing you would tackle with simple pairwise similarity approaches. Biologically, interpreting these data is trivial: S0 is the ancestral genetic variant, S1–S21 are direct derivates of S0, they differ by one mutation from S0 and zero or two mutations from each other (a free-to-use haplotype network software is e.g. NETWORK: https://www.fluxus-engineering.com/sharenet.htm).
Since we usually have no information about how probable a mutation is at a given SNP site, we have no reason to make an a priori difference whether a mutation happened at the first, second, third etc. site when calculating pairwise distances to get "better" similarity measures. What we do when inferring trees is to use the Gamma distribution to model changing rates from site to site.
(Note that NETWORK allows you to reweight each site, in case you have such prior information. Usually reweighting is used to downweigh sites that appear to have high levels of homoplasy, random convergence.)
Regarding the higher mutation probabilty for transitions vs. transversions. All models used for phylogenetic tree inference under Maximum likelihood and Bayesian inference (see e.g. this list: http://www.iqtree.org/doc/Substitution-Models) can also be applied to calculating pairwise distances (implemented in a huge range of tree-inference softwares and R), with the consequence that the pairwise model-based distance between e.g. S0 and S1 (A<>G transition) would be smaller than between S0 and S2 (A<>T transversion), the latter equal to S0 and S4 (A<>T transversion at a different site). Note that RAxML, for instance, the main software to infer maximum likelihood trees these days and analyse extremely large SNP data sets (classic version: https://cme.h-its.org/exelixis/web/software/raxml/index.html; new version: https://github.com/amkozlov/raxml-ng/releases), can export model-based pairwise distances optimised during inferences that take into account not only differences between the substitution categories (A<>C, A<>G, etc.) but, in addition, model per site rate variation using the Gamma function.
So, I'm afraid, there nothing really to research here.
Cheers, Guido.

We know that reflectance is influenced both by solar angle and satellite viewing angle, namely BRDF effects (Bidirectional Reflectance Distribution Function). But few researchers conducted BRDF corrections for water quality remote sensing during model devlelopment and intercomparison between two sensors. Whether or not this issue should be considered? How much accuracy can be improved for water quality estimation if BRDF was corrected?
Relevant answer
Answer
I've done a lot of BRDF work related to vegetation in the past. I'm just starting a project that looks at water dynamics. The main directional issue I've seen over water is specular reflection, which is usually negligible for vegetation. It was an issue when we worked with POLDER data over northern Canada where a ~7km pixel is often a mixture of toundra and small water bodies. Wind will change the reflectance too, but I'm not sure if there is an obvious directionality of that effect.

Let p_{ij} denote the profit gained if parcel j is loaded onto truck i. If the parcel cannot be loaded onto that particular truck, we just set p_{ij} to zero. It looks like we just need to solve the following 0-1 linear program:
maximise
\sum_{i=1}^m \sum_{j=1}^k p_{ij} x_{ij}
subject to
\sum_{i=1}^m x_{ij} \le 1 (for all j)
\sum_{j=1}^k x_{ij} \le 1 (for all i)
x_{ij} \in \{0,1\} (for all i and all j).
If that's right, the problem is very easy. As stated by Przemysław and Helmut, it is equivalent to the linear assignment problem, which in turn is equivalent to maximum-weight bipartite matching.

I want to know what is the logic programming and how can combine the characteristics of the logic programming with the constraint satisfaction in any combinatorial problem 
Relevant answer
Answer
Hi Mai,
Very briefly, logic programming is a programming language paradigm which typically expresses properties of inputs and outputs using first-order clausal logics often with extra notations to control evaluation. Each clause specifies that if a finite number of conditions are satisfied then a conclusion is satisfied. Please see examples in the Wikipedia article and well-known texts such as W.F. Clocksin and C.S. Mellish, "Programming in Prolog", Third ed., Springer Verlag, 1987.
Generally, the method of evaluating programs is under-specified and these languages have been described as "declarative" for this reason, e.g. a program to sort lists often can just be read as a specification of a sorted list. This should be compared to imperative languages where each step of a sorting algorithm is encoded explicitly.
In these languages,  unifiability of first-order predicates is used during evaluation. In constraint logic programming, constraints are added to clauses and need to be solvable too.

David Wolfram

We assume that all the channels to be Rayleigh fading channels, including the residue interference channel. So the SINR at the relay should be
\gamma=|h_sr|^2*P_s/(|h_rr|^2*P_r+N0)
where h_sr and h_rr are the channel gains of the S->R and R->R links, respectively. and N0 is the variance of the AWGN. residue interference are independent with AWGN.
The confusion is here, in some paper I have read thar the average SINR can be calculated as
\bar{\gamma}=mean(|h_sr|^2*P_s) /mean(|h_rr|^2*P_r+N0)
but in my understanding, the average SINR should  be
mean(|h_sr|^2*P_s/(|h_sr|^2*P_s+N0))=mean(|h_sr|^2*P_s)*mean(1/(|h_sr|^2*P_s+N0))
the result will be different. I am a little confused about that.

How we can make the mutation part of an algorithm adaptive? Is there any code for that I can understand the difference?
Relevant answer
Answer
For example in simulated annealing the probability
depends on a parameter that mimics a temperature.
And this temperature drops in time (steps),
therefore the name annealing.
But you could also make the probability or
impact (size) of a mutation dependent on how far
you are off from a good solution.
Suppose you can measure the distance of the
state of your intermediate systems to the
desired solution as a number z between 0 and max,
then you can define p := z/max, and do the
mutation only if a random number r from [0.0, 1.0]
is greater than 1-p.
Likewise you can make the size of the effect
of a mutation dependent on p.

You have all the basics tool needed.  Which and which variant might work best four you depend on the application: classification, recognition, etc.  I think the best way is to create a setup where you can run multiple experiments using these different distances and you improve based on your findings (or stop when it's "good enough")

I'm developing a recommender system for movies using a matrix containing data of films found in DBpedia. However, my matrix contains a lot of missing information (e.g. some films does not contain the year attribute, others the writer etc). So my question is if is it possible to use an imputation algorithm taking into account the features of DBpedia, which is mainly built from a collaborative scenario and therefore prone to errors, and that my information is mainly textual (only the year attribute is numeric). My attributes are Name, Country, Directors, Producers, Starring, Writers, Year, and Subject.  The missing data is denoted with a question mark (?). I've also attached an example of my matrix with only 100 films (the full matrix contains around 101000 films).

Dear Christian
There are some data mining books which provide a section addressing the imputation of missing data. These range from very simple solutions (such as use the most frequent value or the average value) to other more complex. One example is "Data Mining: Concepts and Techniques", by J. Han, M. Kamber and J. Pei.
As an alternative, you can also examine the IMDb data, since it might be less prone to the problem of missing data. Check the below paper for more information:

Long time ago my project was a Greedy router for custom VLSI. On working at a company they used auto routing software, but it did not take detailed account of VLSI design rules (particularly in 3D). Experts would go over the routing & insert "dog-legs" where design rules would cause expansion of the routing. I used a simplified version of the design rule checker, to modify the routine & automatically insert the dog-legs, giving up to 20% reduction in silicon routing usage. That was year ago - I do not know what the state of the art is now.  Chip user manufacturing is a big cost - how many layers are they going to need on there board?  Rather than the academic algorithms, I would look at volume customer requirements first (unless you are working at semi-custom, low volume).

Hi RGaters,
Does anyone know how to modify the order in a sample to modify Kendall's tau value(s) ? Let me clarify what I am looking for. Consider that we have N realizations of K random variables. Each realizations of the group of K variables is independent from the other ones. Inside this realization, the K variables might be independent or not, we do not really care. They even can follow different distributions. The question is the following : from any sample (size N x K) that we call M, can I exchange the places of M[i_1,1] with M[i_2,1], M[i_3,2] with M[i_4,2] and so on, possibly coming back to the first column with an interative algorithm to finally obtain as a result a new (rearranged) sample M' where tau[1,2] = first wanted value, tau[1,3] = second wanted value, and so on, i.e. can I get rearranged data to get a desired tau-matrix. If yes, any algorithm to suggest ?

Hi René,
Thanks for your answer, however, I work in practice with 100 000 * 10 (it's true that I did not mentioned this above) matrices that I want to rearrange this sample to reach a target kendall's tau matrix (as close as possible). It is not the kendall's tau matrix that I want to rearrange, it is the data which lead to this kendall's tau matrix. That'd be too easy :)
Considering this, there is absolutely no way that I try every possible combinations and see which one to choose. I need some intelligent trick such as Cholesky method to get correlate variables.
So basically, it's not only about programming skills, it's also about applied mathematics.

In order to test any event detection algorithm, it is common practice to compute a confusion matrix, in order to get performance parameters (e.g. sensitivity, and specificity). 
It is well known that the confision matrix must be built (identifing and) counting the number of negatives/positives true/false detections, according to a pre-annotated dataset (Gold Standard).
Now, here is my question: how can i identify a true/false positive?
Let me show you a little example.
My algorith wants to detect QRS-Complex's peak, in order to get R-R intervals of a ECG recording. My pre-annotated dataset identify QRS complex not on QRS peak, but some samples before.
It is obvious that, testing my algorithm, i cannot identify a true positive detection "when my algorithm identify the same point as the gold standard", since there's always a time-shift between them. At the other side, all of my detections (because of the time-shift) would be identified as false positives (no time-coincidence with Gold Standard).
An easy solution would be to consider a "coincidence-window" around each point in the Gold Standard but, if i fix the problem with true/false positives, the problem with true/false negatives remains still unsolved.
Has anybody an idea? (Any reference would be great for me).
Thanks a lot.

If I remember correctly: If the process is stationary and the distribution of the random walk is parametric, then state-space methods for time series analysis can be appropriate to use.For example, the R package MARSS implements this. If the distribution of the random walk is non-parametric or the process is not stationary, then simulations need to be employed. Perhaps, particle filtering can be employed.

Hi all,
I am working with 3 others to solve a real life problem for an remote Australian company. The problem is electricians or mechanical fitter travel daily to repair or maintain assets. However they're not aware there could be another near by task they could also do that meats their skill set. So we developed an app to do so. Now i am working on developing a formula for optimization of the daily trip. 
I thought Hamiltonian circuit would be best because they have to return to base at the end of their shift. Also another constraint is they work 9 hours including travel time to and from base. 
Also some of the tasks can take up to 1 or 2 or 3 or 6 or more hours to complete and the travel time could be 2 hours or more. 
I thought they could go out and the jobs that take up the most amount of hours first and on their way back pick up shorter ones. 
Could anyone suggest anything i could do better or use?

Answer
This is a classic problem of the type "vehicle routing with time windows", and its importance has only grown over the years. There is a rather large body of work on this class of problems. I would first study papers discussing mathematical optimization models solved through the use of exact methods, as it is typically those papers that will illustrate what mathematical optimization is capable of, in terms of what you can model, how to model well, and how to efficiently solve these problems.
Look on the web for the paper "The vehicle routing problem: state of the art", by De Jaegere, Defraeye, and Van Nieuwenhuysen from 2014. They appear to have a rather good overview, with plenty of references on what we would call "exact" methods. I think those model-heavy papers are better to start looking at than those that focus on quickly obtaining any solution - I am one of those that like to stare at the mathematical model and try to work out when and why it works, and to try several (equivalent) varieties of the model(s) in order to perhaps find models that describe the same problem but might be solved more efficiently. With todays software and hardware we can solve pretty substantial problems in this class without resorting to heuristics.
