Improving intonation, accent reduction

I need to improve the "impact" of my delivery. This was one of the development needs that my manager has in mind for me.

Thats true, even if you have stuff, and you are not able to convey it in a manner people are impressed, most of the hardwork goes waste..

My voice is monotonous - no up's and down's in the frequency.. It is a drone.. When you listen to me, you would feel that you are listening to a truck that speaks :)..

I also need to improve my accent [So that my US counterparts get me properly]

I need speech processing software to analyse, improve and monitor my voice.

I will keep this post updated with my progress.

I should be done by end of March [Thought it is a continuous improvement process :)]

btw.. Clipmarks is a good mozilla addon to mark the pages that you would like to store..

The best way to improve upon your speech is to be conscious of your speech.

Listen to good speakers[auditory training].
-> Knowledge@Wharton [Management podcasts], BBC and a whole lot of other podcast sites are good sources for materila to listen.

Record your speech [Impromptu speech, reading from a textbook, etc]
Anf then listen to it.. where are the places where you do not sound good, the places where you may be misunderstood, places where you stumble, etc

Note down the areas of improvement.

Practicing in from of the mirrir also helps. Pay special attention to lip movements [In my case, I do not flex my lips to the extent that is needed..]

And.. you need patience.. one cannot perfect it with a day/week etc.. it is a continuous process..

Gene Expression data analysis

Paper: Graph-based iterative Group Analysis enhances microarray interpretation

Gene Expression data analysis :
[from micro array data of a partcular cell state (during a particular phase in the cell cycle/diseased (brain tumor)/healthy) which we want to analyse]
microarray data only gives the magnitude of cDNA's of different genes

One needs to derive the relationships [cause -effect relationships]

• metabolic pathways
• signallin pathways
• protein interaction maps

Identifying subgraphs (that form a community? [PNAS art]subgraphs having high clustering coefficient )

bigraph - Graph with two types of nodes

Good information on the existing methods of Gene Expression Analysis [And gene expression data too]
http://smd.stanford.edu/cgi-bin/search/QuerySetup.pl

good presentation : http://genome-www5.stanford.edu/help/TUTORIALS/SMD_Analysis.ppt

Slide 6 : Factors for Measurement/Process errors
Data smoothened out using normalization : doping controls

Imp: Clustering algorithms
good example begins: slide 21

Heirarchical clustering/Self organising maps

gene Expression microarray data converted into n dimensional vector

x[i] = log(ratio)[i] i=1 to n

How close the two genes are is defined by the distance between those vectors
Metrics:

1. Euclidiean - the distance between the two vectors in space v-u v and u are ntruple vectors
2. Manhattan - http://mathworld.wolfram.com/TaxicabMetric.html
3. Pearson correlation coefficient : It measures the tendancy of both the variables to increase and decrease together.<-- This is also a part of datamining

• This can imply that the change in them is the effect of some other vector
• or both the vectors influence each other [infinite loop till saturation?]
• http://en.wikipedia.org/wiki/Pearson_product-moment_correlation_coefficient

4. Cosine Similarity? [this is used in document similarity] : It is the cosine of the angle between two vectors.

Cluster the expression data [patterns] based upon the similarity[ metrics given above]
Similar to Kruskal's Minimum spanning tree algorithm.

this can lead to erroneous results (why?)

SOM's (self organising maps) <-- This is also a part of datamining
This is a single layer feed forward network connected to a grid of 2D/3D vectors.

Why dont I use edge betweenness based algorithm? [PNAS: community structure in social and biological networks]

Tools:
PAJEK
SMD - Stanford dataset

Good links -

I would like to have a collection of links..
The links which I would like to read at a later point of time..
Bookmarking is one way..
It is a bit difficult to sift thru them.. especially if you have a lots of them..

This is my bundle of good links:
