Assessment is an integral part of learning, and yet very little attention is paid to e-assessment when it comes to e-learning. A significant effort has been directed towards developing high quality question items that take advantage of the new medium, and yet there appears to be some resistance to embrace this new medium. There have been interesting developments in the field of e-assessment. Symbolic systems such as Maple T.A. have matured sufficiently and provide a range of question items. Another significant development is in the area of short answer question items that are assessed that are tolerant to spelling and grammatical mistakes. The advent of digital pens that capture audio and written content opens new possibilities. We can now begin to address diagrammatic reasoning more elegantly. In this paper, we make an attempt to review the state-of-play in e-assessment discussing its pros and cons. Starting with a review of technology landscape, we move on to a discussion of some of the perceived concerns for embracing e-assessment both as a diagnostic, formative and summative assessment tool. The paper concludes with a discussion on timely intelligent feedback which still remains a big challenge, and the opportunities that exists to mediate this issue

Understanding Deep Learning for Big Data: The complexity and scale of big data impose tremendous challenges for their analysis. Yet, big data also offer us great opportunities. Some nonlinear phenomena, features or relations, which are not clear or cannot be inferred reliably from small and medium data, now become clear and can be learned robustly from big data. Typically, the form of the nonlinearity is unknown to us, and needs to be learned from data as well. Being able to harness the nonlinear structures from big data could allow us to tackle problems which are impossible before or obtain results which are far better than previous state-of-the-arts. Nowadays, deep neural networks are the methods of choice when it comes to large scale nonlinear learning problems. What makes deep neural networks work? Is there any general principle for tackling high dimensional nonlinear problems which we can learn from deep neural works? Can we design competitive or better alternatives based on such knowledge? To make progress in these questions, my machine learning group performed both theoretical and experimental analysis on existing and new deep learning architectures, and investigate three crucial aspects on the usefulness of the fully connected layers, the advantage of the feature learning process, and the importance of the compositional structures. Our results point to some promising directions for future research, and provide guideline for building new deep learning models.

Typical approaches of solving classification problems require the collection of a dataset for each new class and retraining of the model. Metric learning allows you to train a model once and then easily add new classes with 5-10 reference images. So we’ll talk about metric learning based on YouScan experience: task, data, different losses and approaches, metrics we used, pitfalls and peculiarities, things that worked and didn’t.

These are the slides of my session and ModConf / Liferay DevCon 2016. It attempts to make it easy for any developer to get started with Machine Learning. It presents three exercises which I'm giving as homework (yup, homework, you missed it, right? ;) to the audience. The video for this session is now available at https://www.facebook.com/liferay/videos/vl.383534535315216/10154154247423108/?type=1 (starts at min 34)

Use linearity of expectation to devise an alternative method of proving the formula E[X] = np where X b(n, p). (Hint See Exercise 2.) Solution A binomial (n,p) random variable can be viewed as a sum of n independent bernoulli trials i. e rv s with distribution bernoulli(p) So if X~bin(n,p) then X=X1 +X2 +...Xn Where Xi ~ bernoulli(p) Hence E(Xi )=p hence E(X)=E (Xi )= E(Xi ) ( By linearity of expectation ) =np.

Underline the most correct choice Trial pits and trenches are the most expensive method of shallow soil exploration (True, False) Sinkholes in soils max be indicated by N: 0-2 SPT values (Ture, False) Milli Gal is a unit for (gravity, magnetic, electrical) surveys. In electromagnetic surveys sandstone shows (low, high) conductivity. Buried mine shafts are indicated by positive next to (+ve, -ve) magnetic anomalies. The most expensive drilling is (rock probing, coring, percussion drilling). You can get aerial photographs in Jordan from (NRA, RJGC, Water Authority) For road lines, site investigation boreholes should be ( Solution 1. Yes Trial pits and trenches are tho cheapest method of exploration in shallow deposits, since these can be used in all types of soils. In this method, pits are excavated at the site, exposing the sub- soil surface thoroughly. Soil samples are collected at various levels. The biggest advantage of this method is that soil strata can be inspected in their natural condition and samples (disturbed or undisturbed) can be conveniently taken. 2.no,sinkholes is indicated by depth 3.Gravity The SI derived unit for acceleration is the meter/square second. 1 meter/square second is equal to 100000 milligal. 4.low The electrical conductivity of rocks results from conduction through the bulk solution occupying the pores and from surface conduction occurring at the fluid/grain interface. The nature of the surface electrical conductivity of shaly and clean sands and sandstones is examined. Surface conduction is characterized by the specific surface conductance which is the sum of three contributions: (i) Conduction within the electrical diffuse layer, which makes a negligible contribution to the total specific surface conductance, (ii) Conduction in the Stern layer, which is shown to vary significantly with the salinity of the pore fluid at low salinities (106 to 103 mol 11), but becomes independent of salinity at higher salinities, (iii) A mechanism operating directly on the mineral surface, independent of salinity, and perhaps associated with proton transfer. At salinities higher than 103 mol 11 and at 25°C, the specific surface conductance of quartz and clays is equal to 8.9×109 S and 2.5×109 S respectively.

Two cards are randomly drawn with replacement from a well shuffled deck. What is the probability that at least one is a heart? (There are two ways to solve this problem.) Solution We can solve this problem using the binomial distribution p = .25 = probability of pulling a heart. Since the cards are replaced the probability of pulling a certain color does not change after the first card is drawn. n = 2 = total number of cards drawn x = number of hearts drawn P(X >= 1) = 1 - P(X < 1) = 1 - P(X <= 0) = 1 - P(X=0) =.

Solution (a) Given a=0.1, Z(0.05)=1.645 (from standard normal table) Lower limit = xbar-Z*s/vn = 14.3 -1.645*2.6/sqrt(200) =13.99757 Upper limit = xbar+Z*s/vn = 14.3 +1.645*2.6/sqrt(200) =14.60243 (b) Given a=0.02, Z(0.01) =2.33 Lower limit = xbar-Z*s/vn = 14.3 -2.33*2.6/sqrt(200) = 13.87163 Upper limit = xbar+Z*s/vn = 14.3 +2.33*2.6/sqrt(200) =14.72837.

True or false: Young lavas are generally good aquifers. Basalt is a good aggregate and valuable roadstone. Basalt is rich in quartz. Muscovite is more resistant to weathering than biotite. Larvikite is a dark coarse granite with distinct internal reflections. Dolomite is weaker than calcite. Chert is a volcanic rock. Travertine is a marine limestone. Hade angle is > 90 degree. Camber folds are tectonic compressive structures. Solution 1) True, Young lavas can be good aquifer. The lava contains mainly pores in them which can hold water. This young lava after cooling can have pores filled with water. 2) True, Basalt has good strengthm, are durable and have better thermal properties. Hence it is a good aggregate and roadstone. 3) True, Basalt has 50% of quartz in composition. 4) False, Muscovite is very thin as compared to Biotite. Hence it is very liable to weather compared to Biotite. 5) True. 6) False, Though the hardness of both the rocks are same i.e. 3. Dolomite is slightly harder and denser than calcite. 7) False, Chert is sedimentary rock i.e. they are sediments due to water around the rivers, lakes, sea, ice, wind etc. 8) True, It is a limestone usually deposited by mineral hot springs. 9) False, Hade angle is 90-Dip angle hence it should be less than 90 degree. 10) False. Camber folds are non structre folds hence they are not compressive structures..
